Spring is a good time to begin growing and digging, although planning can take place before the snow melts. Gardeners spend most of the summer watering, weeding, and watching young plants grow. Fall is a good time to plant trees, shrubs, bulbs, and some perennials.
1. Get an idea. Is this going to be a vegetable garden? An herb garden? A flower garden? If you choose to grow flowers, do you want annuals, which you must replant each year but which give color most of the summer? Or do you prefer perennials, which have a shorter bloom time but come back year after year? You can mix any of the above—after all, it's your garden.
2. Pick a place. Almost all vegetables and most flowers need about six hours of full sun each day. Spend a day in your chosen spot and watch how the sun moves across the space. It might receive more sun than you think. But don't despair if your lot is largely sunless; many plants tolerate shade. Check plant tags or ask the staff at your local garden center to find out how much sun a plant requires.
3. Clear the ground. Get rid of the sod covering the area you plan to plant. If you want quick results, you can dig it out, but it's easier to smother it with newspaper. A layer of five sheets is usually thick enough. Spread a 3-inch (7.5 cm) layer of compost (or combination of potting soil and topsoil) on the newspaper and wait. It'll take about four months for the compost and paper to decompose.
If you don't want to wait or if the area is covered with weeds, you're better off digging the sod out.
4. Improve the soil. Invariably, soil needs a boost. The solution is simple: organic matter. Add a 2- to 3-inch (5 to 7.5 cm) layer of compost, decayed leaves, dry grass clippings, or old manure. If you dig soil, till the organic matter into the soil. If you decide not to dig or are working with an established bed you can't dig, leave the organic matter on the surface and it will work its way into the soil in a few months.
5. Dig or don't. Digging loosens the soil so roots can penetrate more easily. But digging when the soil is too wet or too dry can ruin its structure. Dig only when the soil is moist enough to form a loose ball in your fist, but dry enough to fall apart when you drop it. Use a spade or spading fork to gently turn the top 8 to 12 inches (20 to 30 cm) of soil, mixing in the organic matter from Step 4. In vegetable gardens and beds of annual flowers, turn the soil only once a year in the spring before you plant.
6. Pick your plants. Some people pore over catalogs for months; some people head to the garden center and buy what wows them. Either method works if you choose plants adapted to your climate, your soil, and the amount of sunlight in your garden. You can even surf the Internet for plants to purchase. Here are a few easy-to-grow plants for beginners:
- Annual: Cosmos, marigolds, Impatiens, Geraniums, Calendula, sunflowers, and Zinnias
- Perennials: Russian Sage, Lamb's Ears, Black-eyed Susans, Purple Coneflowers, Phlox, pansies, and daylilies
- Vegetables: lettuce, peppers, tomatoes, and cucumbers
7. Put them in the ground. Some plants, such as pansies and kale, tolerate cold, so you can plant them in autumn or late winter. Tomatoes and most annual flowers, on the other hand, are touchy about cold, so don't plant them until the danger of frost has passed in your area. Midspring and midautumn are good times to plant perennial flowers.
Some plants, such as lettuce and sunflowers, are easy to grow from seed. You can sow them directly in the garden. Be sure to read the seed packet for information about when to plant, how deep to plant, and how far apart to plant the seeds. If you're an adventurous beginner, you can get a head start on the growing season by sowing seeds indoors before the last frost date. You can buy containers or flats designed especially for seedlings, as well as seed-starting soil mixes (available at garden centers). Follow seed-packet instructions, and place the containers on a sunny windowsill or under artificial lights if you don't have window space. Be sure to keep the seeds and seedlings moist but not wet (or they may rot).
An easier method is to buy young plants, called set plants or transplants. Just dig a hole and plunk them in the ground.
8. Water. Seedlings should never dry out, so water daily while they are small. Taper off as the plants get larger. New transplants also need frequent watering—every other day or so—until their roots become established. After that, how often you need to water depends on your soil, how humid your climate is, and how often it rains. Plants are begging for water when they wilt slightly in the heat of the day. Water slowly and deeply, so the water soaks in instead of running off into the street. To minimize evaporation, water in the early morning.
9. Mulch. To help keep weeds out and water in, cover the soil with a couple of inches of mulch. All sorts of mulch are available, from pine needles to cocoa hulls to bark chips. For a vegetable garden or bed of annuals, choose a mulch that decomposes in a few months. For perennials, use a longer-lasting mulch, such as bark chips.
10. Keep it up. Your garden is on its way. Keep watering when needed, and pull weeds before they get big. Fertilize with a dry fertilizer about halfway through the season. If you use a liquid fertilizer, fertilize every month or so.
