Begonias, such as this Skaugum Begonia, are well-suited to containers.
Growing in containers saves space, but it's also a smart alternative if you are restricted by too much shade, poor soil, too little time, limited mobility or a difficult climate. Container gardens can be much more productive than a regular garden while allowing you to avoid most pest and disease problems. Best of all, it brings your garden right up close, creating a sense of intimacy that you don't get in an ordinary backyard garden.
Almost anything can serve as a container for growing plants. In addition to terra cotta, plastic or pressed fiber pots, you can use recycled whiskey barrels, 5-gallon food buckets, bushel baskets, plastic tubs, wooden planter boxes, even old tires! Self-watering planters, which have built-in water reservoirs, are great innovations.
The size of container that you use should be determined by the plants you plan to grow. Begonias may get by in a 6-inch deep container, but don't try to grow a canna in a container that holds less than 3 gallons of soil. The general rule is to use the largest container possible, because the more soil there is, the more root space there will be—and the longer your plants can go between waterings.
Make sure the containers have drainage holes—on the sides rather than the bottom if possible—so excess water can drain and roots won't get waterlogged. For large pots with drainage holes on the bottom, elevate the pots on bricks or scraps of wood so that the water can escape.
In general, a 20-gallon pot should have four to six 3/4-inch holes; a 30-gallon pot should have at least eight 1-inch holes. You can put stones or bits of crockery in the bottom of the pot, but with a well-aerated soil mix, this is unnecessary and will only steal valuable root space.
Once you have chosen the right container, you are ready to pick a soil mix. Soil for container-grown plants should be light and friable, well drained and moisture-retentive. Garden soil is much too dense and can introduce disease and insect problems. Most container-grown plants are happiest in a soilless blend comprised of sphagnum moss, vermiculite or perlite, with the addition of finished compost.

It's easy to purchase a pre-mixed blend, but you can also create your own mixes, using the following recipes as a guide.
Organic Blend: 5 gallons finished compost, 1 gallon builder's sand, 1 gallon vermiculite or perlite, 1 cup granular-all purpose organic fertilizer.
Standard Blend (Cornell Mix): 1 bushel vermiculite, 1 bushel ground sphagnum moss, 8 tablespoons super phosphate, 8 tablespoons ground limestone, 2 cups bone meal.
Light Blend (for rooftops): 5 gallons ground sphagnum moss, 5 gallons vermiculite or perlite, 2 gallons compost, 1 cup granular all-purpose fertilizer.
Any soil mix will become compacted over time. If your containers seem water-logged and heavy, you may need to replace your soil mix at the start of a new growing season with a fresh mix.
If you go off to work in the morning without watering your windowboxes or patio containers, you are likely to come home to droopy, if not dead plants. When plants get too dry, their delicate feeder roots die and the plant must concentrate its energy on re-growing damaged roots rather than producing fruit or flowers.
That means unless you use self-watering planters or have a drip-irrigation system, you'll probably need to check on your plants daily, and maybe even twice a day if the weather is really hot. If you have more than a few planters, and especially if you travel, a drip-irrigation system is ideal.
Three Watering Innovations for Containers
Because most potting mixes provide few nutrients, your plants will be totally dependent on you for their food. Add granular organic fertilizer at planting time, then water weekly with half-strength, water-soluble fertilizer. Foliar feed with seaweed or fish emulsion for a quick pick-me-up if your plants look stressed or have been cut back.
Each week during the growing season, remove spent flowers and pinch back leggy stems. When necessary, replace tired plants with some fresh annuals, especially late-season favorites, such as ornamental kale and mums.
If you plan to overwinter some of your potted plants, they should be cut back and put in a cool location. Water sparingly and do not fertilize until spring. Once warm weather arrives, remove plants from their containers, tease away old soil, and repot the plants in a fresh soil blend.
Some sort of vertical support is a necessity for container-grown tomato plants, cucumbers, and flowering vines. Trellises can also add a beautiful vertical accent when covered with morning glories or sweet peas. Keep the scale of the trellis in proportion to the pot, and be sure to attach it securely using brackets or wires. Losing a mature tomato plant or flower-covered trellis to an August thunderstorm can be heartbreaking.
This planter has been layered with bulbs, which ensures a longer season of bloom.
If you are short on garden space or do not have access to a garden, you can still enjoy the beauty of spring-flowering bulbs. Most spring-flowering bulbs can be grown in a container as well as in the garden. To be successful requires some special attention, but the colorful spring results are well worth the effort. The one essential step is to expose the potted bulbs to at least 12 weeks of temperatures between 32 and 45 degrees F.
You can choose your own bulbs, or, to make things simple, you can use Dutch Gardens' Bulb Beds for Pots. The planting trays are made to fit a 10- to 12-in. pot.
Choosing a Container: The size of container that you use should be determined by the number of bulbs you want to plant. Regardless of the diameter of the pot, we recommend using a container that is at least 8 inches deep. Make sure the container has drainage holes—on the sides rather than the bottom if possible—so excess water can drain and roots won't get waterlogged. Self-watering pots are not recommended for growing spring-blooming bulbs.
Choosing a Potting Mix: Once you have chosen a container, you are ready to select a soil mix. Soil for container-grown plants should be light and friable, well drained and moisture-retentive. Garden soil is much too dense and can introduce disease and insect problems. Your bulbs will grow best in a soilless blend comprised of milled sphagnum moss and vermiculite or perlite, with the addition of some finished compost.
Drainage: When spring-blooming bulbs fail to flower, it's most often because the bulbs have been too wet during the winter. To ensure good drainage, we recommend lining the bottom of your container with an inch or two of stones or pieces of broken pots. Make sure that excess moisture can drain away so the pot is never in standing water.
Start by placing several inches of potting mix on top of the drainage material. Big bulbs, such as tulips and daffodils, should be planted 6 inches deep. Smaller bulbs, such as crocuses and muscari, need to be about 3 inches below the soil surface. Place enough soil on the bottom of your container to allow for the proper planting depth of your bulbs, taking into account that the finished soil surface should be about 1-inch below the top of the pot.
If you will be planting more than one type of bulb in the same container, plant the bulbs with the deepest planting requirement first (tulips and daffodils), followed by an inch of two of potting soil. Then add the bulbs that have shallower planting requirements (crocus and muscari). This planting technique, called layering, will provide you with a succession of blooms and give your container a very full look.
Watering: After planting, water the container thoroughly. Don't allow the soil to dry out completely during the winter. If you don't receive enough rain to moisten the soil or if you are storing the container in a covered area, such as a shed or garage, water the container regularly enough to maintain "barely moist" soil-about once a month.
Cold Protection & Cold Treatment: For proper flower formation, spring-blooming bulbs must be exposed to a minimum of 12 weeks of temperatures below 45 degrees F. If you are growing spring-blooming bulbs in containers, here are a few things to keep in mind:
Skilled designers combine plants and "hardscape" (stone, fencing, lighting and decorations), to create a beautiful garden.
Experienced gardeners have no problem deciding when to plant their peas, how deep to put their tulip bulbs, or how much to water their geraniums. But when it comes to garden design, even the most seasoned gardeners begin to sweat. We can spend weeks trying to find the perfect spot for a new shrub; spend an entire winter sketching plans for a new perennial garden; and agonize for years about how to reconfigure the front walk. Why do we find these decisions so paralyzing?
One reason may be that garden design is perceived as the work of experts: landscape architects, landscape designers, garden designers, and landscape contractors. Yet some of the most beautiful gardens in the world were not designed by experts. Sissinghurst, the home and gardens of Vita Sackville-West and Harold Nicolson, is a perfect example. So, too, are the gardens of Tasha Tudor and Thomas Jefferson. These gardens are the result of an attentive eye, a sensitive hand, and many years of experimentation—skills that are not the exclusive property of design professionals. Our goal in this article is to help you overcome the garden design jitters, and give you the confidence to finally remove that hedge of overgrown yews, install a flagstone path, or decide where to put a water garden.
Some gardeners wouldn't dream of planting anything without having a comprehensive design and planting plan for their entire yard. Others don't think about "designing" their gardens until several years down the road. And still other gardeners never develop a long-range or a short-range plan. They do their planning in the moment, poised with a shovel and a couple of homeless plants.
Which approach is right for you? It depends entirely on who you are and what you are comfortable with. If you have the confidence to forge ahead and follow your intuition, do so! If you feel the need to get some professional advice, then that's the best alternative for you. Both approaches are equally valid.
It is good to remember that there is no ultimate garden design for your property. There are as many different designs as there are gardeners. And even if you had a detailed plan that you executed perfectly, tomorrow would bring a new interest, a new challenge, and a whole new set of design decisions. The trees will mature and turn your sunny meadow into a shady glade. The weeping cherry that anchored your spring bulb garden will die and need to be replaced. You will tire of the cottage garden and develop a passion for dwarf conifers. In garden design there are no "right" decisions. What you have is a delightful (though sometimes unnerving) opportunity to express yourself. The hardest part may be trusting your own intuition, and allowing yourself to experiment as you evolve your own unique garden design.
One of the most valuable design tools is a site plan, or bird's-eye view of your yard. Seeing your garden on paper makes it much easier to identify underlying design elements such as traffic patterns, scale, and symmetry. A professional designer will give you a site plan that is precisely drawn to scale, but your own rough sketch or a survey map will be adequate for all but the most complex landscape designs. Once you have a plan to work from, you can start to indicate the positive and negative features of your yard (trees, shrubs, fences, outbuildings, pathways, views) and natural environmental factors such as light conditions and soil or drainage problems. Pathways and garden areas can be sketched right on the plan. If you enlarge sections of the plan, you can also use it to create your planting map.
Should you hire a professional landscaper or garden designer to help you with your site plan? If you have the means and desire to do so, it will probably be money well spent. Professional advice will always give you a valuable new perspective on your yard and gardens. You may follow their recommendations to the letter, or select only the elements that you find most appealing or most manageable. It is not necessary to contract for a full-scale site plan. Most designers will be very willing to focus their attention on a particular area (like the entryway). One well-conceived and well-executed feature may go a long way toward identifying a design style that you can then carry forward yourself.
What follows is a list of design principles that are common to all the creative arts, whether it be painting, music, literature, or garden design. Don't let them intimidate you. Just use them as tools to help you see.
Style. Every garden has a style or personality to it. Unless you have a very large yard that is divided into distinct areas or "rooms," it can be difficult to gracefully accommodate lots of different garden styles in one garden. Begin by thinking about whether you want your garden to have a formal or informal look. Consider your site, the style of your home, and your own personality. Though you don't have to be too rigorous about striving for a consistent style, you'll want to avoid a jumble of diverse and unrelated elements.
Flow. A garden is more pleasing if there is a logical progression from one area to the next. Think about how you would like someone to view and move through your garden. Paths are one way to connect some of the various parts to achieve a sense of order and cohesiveness. Focal points, such as a piece of sculpture, a distinctive tree, or a captivating view, can be used to draw the eye and pull us forward into a new space.
Scale. Scale is about proportions - how the sizes and shapes of things relate to each other. A 3 x 6-foot island bed floating in a half-acre sea of lawn will be seriously out of scale. The same will be true of a dwarf apple tree located in front of a two-story colonial house. Most scale problems are due to skimpiness, such as beds and paths that are too narrow, or plantings that are too small and tentative. If in doubt, err on the side of boldness and generosity.
Rhythm. By repeating plants and materials, you can produce a sense of rhythm, order, and predictability. Too much repetition is monotonous, but, as in music, variations on a theme are pleasing. You may want to repeat certain distinctive plant materials, such as the spearlike foliage of an ornamental grass or the velvety gray of lavender or santolina. Repeating splashes of color will also establish a rhythm in the garden and help to guide the eye. But don't be a slave to repetition. The best gardens always leave room for the unexpected—a giant pot of agapanthus, a whimsical birdhouse in a tangle of morning glories, or a blood-red rose tumbling over a stone wall.
Symmetry and balance. Humans seem to be naturally attracted to symmetry—toward creating perfectly balanced features. Our bodies are symmetrical, as are the cars we drive, the arrangement of windows in our homes, and often the shrubs that flank the front door. Used judiciously, perfect symmetry can be a powerfully appealing design technique. But when overused it can become stiff and boring. The natural landscape, which we also find visually pleasing, is not governed by symmetry. In nature, something more subtle is at work, something artists and designers refer to as balance. Balance is an essential factor in garden design. It refers to visual weight: a birch clump balanced by a large bed of hosta; a brick pathway balanced by a wide swath of lawn; orange Oriental poppies balanced by deep blue lupines. In these examples, the two elements are not identical in size, shape, or color, but there is a response from each side that balances the other. Successful garden design incorporates both symmetry and balance.
One thing great gardens share is a sense of place. Entering them is like entering a home—you are wrapped in a particular environment that is very different from the world outside. As in a home, the walls, roof, and floor help give a garden its unique character. When designing your own garden, you can use these aspects to create "rooms" in which plants are arranged in a context rather than floating in space.
Walls. English flower borders almost always have a background behind them. In England, this is usually a tall stone or brick wall or an evergreen hedge. The backdrop serves to stop your eye from roving and allows you to focus on the intended view. Most American gardeners don't make use of this very effective technique, and our gardens often get lost in the larger scene. Whenever possible, anchor your garden by placing something behind it: a structure, a fence, or a planting of shrubs. Remember to keep it simple. The objective is to direct the eye to the foreground, not create a competing element.
Roofs. Though there are plenty of very successful gardens that are totally exposed to the sky, most of us are naturally attracted to more sheltered, intimate spaces: a garden that's been carved out of a woodland or is nestled beneath an ancient apple tree. We are, for the same reason, drawn to arbors, bowers, allees, and pergolas. The roof need not cover your entire garden. Including the experience of enclosure somewhere in your garden—it can be as simple as an arbor at the entrance—will help to create that sense of being in a special environment set apart from the rest of the world.
Paths. Paths lead us through a garden and link one area to another. Paths in themselves are an age-old comfort, showing us the way we are to travel, assuring us of a progression that is safe and intentional. The paving material and the way the paths are laid out can help define the style of the garden. A meandering pathway made of flat stones spaced several inches apart will have an intimate, informal feel; a wide brick path suggests neatness and order; a broad path of closely mown lawn conveys grandeur and expansiveness. Paths also create edges that suggest where new plants or even entire gardens could be located.
Plants themselves can be important design elements, though few gardeners actually use them this way. The arching branches of a well-pruned cherry tree can frame an entire garden. The repetition of the spiky foliage of Japanese iris can be used to unify a long border. If you take the time to notice and experiment with the form, texture, and color of plants, you will discover a whole new palette of design elements with which to work. form. This is a three-dimensional consideration that takes into account the shapes and volumes of the plants in your garden.
A variety of different forms makes a garden interesting, but too much diversity can create visual confusion. Trees and shrubs often have characteristic forms that should be carefully combined to avoid clashing. Flowers, too, have characteristic shapes: the rounded heads of alliums, verbena, and globe thistle; the vertical spikes of delphinium, snapdragons, and veronica; the diaphanous look of baby's-breath and Queen Anne's lace; the strong architectural lines of a 5-foot martagon lily. You can experiment by grouping plants with the same form into a drift, or by repeating a pleasing composition of different forms several times.
Texture. Plants have a tactile quality that can be used as a valuable design tool. Think about how the glossy leaves of holly, magnolia, and roses contrast with the suede-like foliage of lamb's ears, heliotrope, and coleus. Or how the fat and fleshy leaves of a sedum differ from the needle-like foliage of rosemary or the quilted leaves of a blue-green hosta. Flowers also provide textural interest. They can be rich and velvety like a rose, or as thin and translucent as a poppy. Even tree bark contributes textural interest - especially during the winter months.
Color. Entire books have been written about using color as a design tool. You can approach color as a technician, using the color wheel to create harmonious combinations, or you can use your own eyes and emotions to guide you in creating the look and feel you want. Combining colors in new and interesting ways offers a lifetime of exciting possibilities.
As a general rule, red, orange and yellow are colors that jump out at you. They are lively and stimulating, and give the impression that they are closer to the eye than they actually are. If you plant too many hot-colored flowers, and don't balance them with cool-colored, less assertive plants, your garden will be a jumble of blaring trumpets. Green, blue, and violet are cool colors. In the garden these flowers create a more soothing, restful feeling, and tend to recede into the distance.
Visiting other people's gardens may be the best source of design inspiration. Take along a camera or sketch pad to capture features that you find particularly successful or appealing. Notice when some of the design techniques described above are being used. Don't be afraid to ask questions about what the gardener was trying to achieve.
Glossy picture books of gardens run a close second for design inspiration. They have the distinct advantage of being available for perusal year-round. Use sticky notes to mark images that capture your attention, then go back and review your choices to see where the similarities lie. Comparing and contrasting different types of gardens can be very useful in helping you decide what sort of look attracts you. If you are gravitating toward a theme garden (colonial, Japanese, Southwestern, English cottage), you'll find dozens of books that illustrate the design features and techniques that distinguish these styles.
Some garden design books include complete planting plans that are theme-oriented, or are specific to a certain type of site. They usually provide a site plan, a planting list, and an elevation drawing that shows what the garden will look like at eye level. You can follow the plan, or pick and choose the elements that appeal to you.
Creative gardeners read garden design books the way creative cooks read recipe books. Don't feel compelled to follow the garden design verbatim. You can lift ideas here and there, and combine them into your own unique expression.
Some purists believe that ornamentation—trellises, furniture, sculpture, and decorative planters—has no place in the garden. Others fill their gardens with so many decorative elements that it can be difficult to find the plants. Used judiciously, the furnishings and decorative features that you incorporate in your garden help give it style and character.
Decorative elements can be characterized as formal, informal, or somewhere in between. This has something to do with what the piece is (a whirligig versus a Japanese lantern), but also what the piece is made of. Fanciful wooden birdhouses and split-rail fencing have a casual, country feeling; whereas a bronze nude or a Grecian urn are more elegant and formal. When choosing decorative elements for your garden, the challenge is to select items that appeal to you, and that will also fit harmoniously with the style you are trying to achieve and any other decorative objects that you already own.

Gardeners usually consider shade a liability. It's true that a shady yard is not a good place for growing beefsteak tomatoes, roses and delphinium. But a shady garden can provide a type of pleasure no sunny garden can touch. Like the soothing comfort we feel beneath a shady tree on a hot summer day, a shade garden is restful to the eye and calls us to slow down and look more closely.
There are some other good reasons to be happy about gardening in the shade. Plants grow more slowly in shady conditions, reducing the need for dividing and pruning. Weeds also grow slower and are less of a problem. And a shady garden's combination of dense foliage, cooler soil and less wind, also keep watering chores to a minimum.
To be a successful shade gardener, there are three important factors to consider: amount of shade, soil conditions and plant choice.
First and most important, is to understand how much light your plants will actually be receiving. Determining whether you have partial, light, full or dense shade will allow you to match the right plants to your growing conditions.
Partial Shade: This is sometimes also called semi-shade or part shade. It means that the site receives full sun for several hours a day, but is in light or full shade for the rest of the day. If you have the choice, morning light, when air and soil temperatures are cooler, is preferable to afternoon light, which can be hot and drying.
Light Shade: This might also be called dappled shade. It refers to filtered light through a lacy covering of overhead leaves, or one that is lightly shaded by a high canopy of leaves. If your garden is in a tree-filled yard, one way to create this quality of light is to "limb up" selected trees, removing low branches and increasing the overall light levels.
Full Shade: Though not considered dark, a full-shade location is nearly always in shade. It is still open, with good air circulation, good soil and adequate moisture.
Dense Shade: When the ground is completely shaded by buildings or is under the thick shade of trees such as Norway maples and evergreens, little light reaches the soil surface. These are difficult growing conditions for all but a few types of plants.

Not realizing this Toad Lily (Tricyrtis formosana) was more unique than other lilies, I was anticipating an earlier bloom, and a larger flower. But how much more delighted I was when these finally emerged at the end of the summer! Thank you for offering such resilient and beautiful flowers!"
In nature, most shade-loving plants grow in the forest understory where the soil is airy, moist and rich in organic matter from many years of falling leaves. As a general rule, shade-loving garden plants will be happiest if you can provide them with these same soil conditions.
Tree roots can present a significant challenge to the shade gardener. A mature tree can easily drink several hundred gallons of water a day. Most of this moisture is drawn up by a web of fibrous feeder roots that lie just inches below the soil surface, leaving little water for plants growing at their feet. Many shade gardeners find dry soil to be a greater problem than limited light.
Fortunately, even the driest, stoniest, most infertile soil can be improved over time by a diligent gardener. If you are starting a new garden in a shady location, it's well worth spending time to prepare the soil. If you have the patience, begin that work a full year before anything gets planted. Start by removing any sod, or cover the area with black plastic to kill the grass. Spread a 6-inch layer of shredded leaves and compost over the area and then either dig that organic matter into the soil or cover it with a water-permeable tarp and let the soil microbes do the mixing. It's a good idea to check the soil pH as well. Most shade-loving plants prefer a neutral to slightly acid pH.
Once your new garden has been planted, mulch around the plants with shredded leaves or bark, and water regularly until the plants are well established. This extra attention may be required for a year or two, but once the plants' roots are firmly anchored and their foliage is shading the soil surface, most shade gardens will happily coexist with all but the thirstiest of trees.
Shade gardens are not about flashy colored flowers. Flowers are a bonus—not the main objective. A shade garden is all about the interplay of foliage in its various colors, shapes and textures. As you become familiar with the vast palette of shade-loving plants, you will be amazed and inspired by the beautiful combinations you can create.
Foliage colors range from golden yellow through hundreds of different greens and into blues and even burgundy. Leaves may be smaller than your thumbnail, or bigger than a beach ball. Textures range from felted to shiny, smooth to ribbed. Add a few flowers, and the possibilities are simply endless.
