The best advice for planning your first vegetable garden is to start small. Just be sure you locate your garden in a sunny spot where expansion is possible. As for actual size, it depends on what you want to grow. Here's what you can put in the following standard-size gardens: A 6 x 8 foot plot can support a couple tomato plants, maybe some bush beans, and some lettuce. A 10 x 18 foot plot can hold all that, plus a couple space-consuming squash plants and cucumbers, and maybe some carrots or beets. A 20 x 24 foot plot can hold all that, plus peppers, leeks, broccoli, turnips, and maybe some herbs. A 40 x 60 plot allows you more of everything, plus some bigger items, such as corn (corn isn't worth growing unless you can have a dozen or more plants because otherwise they don't pollinate or pollinate completely, and you end up harvesting gap-toothed ears) and asparagus or rhubarb. Sketch out your vegetable garden plan on paper before planting. Figure out how much space to allot to individual plants — and don't forget to allow for space between the rows, or paths, so you can tend the plants. (Mature sizes of various vegetable varieties are noted on seed packets and often in catalog descriptions.) Allow for succession planting: If something is harvested early in the summer, lettuce, say, or peas, you can then free up that space for another crop, such as carrots. Succession planting is a good trick, but to pull it off, you may need to do some research as well as some trial and error — and be willing to invest the time and effort. You could also plan for a constant vegetable harvest by intercropping, or interplanting. This method is simple: Just have two different plants share the same part of the garden in an alternating or checkerboard pattern. This setup can look rather nifty, but it has practical advantages as well. Smaller, faster-maturing plants can grow with larger, slower-growing ones and so you always have something to harvest. And plants that appreciate a little shade can grow in the shelter of taller ones (have pole beans next to lettuce or spinach, for example).

Don't be afraid to repot your orchids while caring for them. Despite their reputation, orchids are tough, and repotting helps them thrive. You'll know it time to repot orchids when Orchid roots are overflowing the pot The plant itself is going over the edge of the pot Potting material is getting soggy and drains poorly The ideal time to repot most orchids is when the plant starts new growth — usually right after it finishes flowering. Prepare the potting mix Choose a potting mix that suits your particular type of orchid. Whether you mix it yourself or buy it ready-made — it must be wetted before you use it. Otherwise, it'll never hold moisture properly and will always dry out. Here's how you prepare the orchid mix for potting: Pour the amount of potting material you intend to use into a bucket that has about twice the volume of the mix. Fill the bucket with hot water. Hot water penetrates the material better than cold water. Let the mixture soak overnight. The next day, pour out the mix into a colander or strainer. Rinse the mix thoroughly to wash out the dust that was in the mix. Now the mix is ready to use. Time to repot When you're ready to repot the orchid, spread out some newspaper over a work surface. Gather up a knife, scissors, new orchid pots (or old ones that are thoroughly cleaned), wooden stakes, and soft ties. Now, follow these steps: Remove the orchid from the pot. You may need to use a knife to circle the inside of the pot and loosen the roots. Remove the old, loose, rotted potting material and any soft, damaged, or dead roots. If the roots are healthy, firm, and filling the pot, put the orchid in a pot just one size larger than the one you removed it from, placing the older growth toward the back so the new lead or growth has plenty of room. If the roots are rotted and in poor condition, repot the plant in a container of the same or one size smaller than it was removed from. If you place a poorly rooted plant in a container that's too large, the growing material will stay too damp, which will result in root rot. Some orchid growers like to add a coarse material like broken clay pots or Styrofoam in the bottom of the pots to improve drainage. You don't have to do this if you're using shallow, azalea-type pots. Place the plant in the pot so it's at the same depth as it was originally. The new shoot should be level with the pot rim. Press the fresh potting material into the pot and around the orchid roots with your thumbs and forefingers. The orchid should be secure in the pot so it doesn't wiggle — otherwise, the new roots won't form properly. Place a wooden or bamboo stake in the center of the pot, and tie up the new and old leads with soft string or twist ties. When orchids are in bloom, the staking techniques will vary, depending on the type of orchid. Monopodial orchids are those with one growing point that always grows vertically, not sideways (such as phalaenopsis, angraecums, and vandas). The potting process for these orchids is similar to the process just outlined, except that the orchid should be placed in the center of the container, rather than toward the back.

Whether you're a novice or experienced gardener, embrace water-conservation methods even if you don't live in a water-restricted area. Conserve water as you garden, and you'll help save this precious resource and save some money, too. Keep these water-saving pointers in mind when tending to your garden: Grow plants that perform better under low water conditions: Some drought-resistant food crops you might try include herbs and hot peppers. For flowers and other ornamentals, consider native plants and wildflowers, ornamental grasses, and succulents. Plant closer together: Doing so allows you to conserve soil moisture and shade the ground, keeping it cool and moist. Consider the time of day that you water, especially if you use a sprinkler: You lose less water to evaporation (an important consideration in hot, dry climates) if sprinklers operate in the cool of the morning rather than during the heat of the afternoon. Watering in the morning also gives leaves a chance to dry off before evening; wet foliage is an ideal fungus-growing medium. Frequent, shallow waterings do more harm than good: They cause roots to develop mainly in the upper few inches of the soil, where they're susceptible to drying out. Instead, go for occasional, deep waterings. Deep waterings allow moisture to penetrate deeply into the soil. The roots will follow the water, and the plant will be deep rooted and less likely to be effected by dry conditions. You'll water less frequently; maybe deeply once per week. If your garden has heavy clay soil or is on a slope, and you find that water begins to run off before it penetrates 6 inches deep in the soil, try watering at intervals: Water for 10 to 15 minutes, let the water soak in for 15 to 20 minutes, and then water again. Try to use soaker hoses and drip irrigation to direct water to the plants and not waste it on pathways: Use a timer to turn on the system during cool parts of the day for only as long as needed. Collect rainwater from roofs and store it to be used in the garden: Rain barrels (often used with rain gardens) are becoming more widely available. In some areas you can even use gray water from your home in your yards. Check with your local water municipality for regulations on using gray water. Apply mulch, which helps retain moisture and keeps soil from drying out quickly.

Gardeners in northern regions deal with warm summers and cold winters. But there is work to do in your garden through most of the year. Here is a month-by-month guide that keeps you in the gardening frame of mind, even through the dreary months of winter. Winter January: Settle next to the fire with a stack of new seed catalogs. As you order seeds, think about where you want to plant new annuals and what color combinations you find appealing. February: Prepare a space for starting seeds. Clear an area in a sunny window or set up fluorescent lights for seedlings to sprout and grow. Buy seed-starting trays or use old trays that you’ve cleaned with a dilute bleach solution and rinsed well. Providing bottom heat maintains an even, warm soil temperature and improves germination. March: March through mid-April is seed-starting time in cold climates. Plan a seeding schedule — essential in short-season climates where you want to make every day count. Start by figuring when you want to move plants into the ground, and work backward to calculate the best time to sow the seeds indoors — four to eight weeks ahead of transplanting time, in most cases. Also see these month-by-month chores for gardeners in other U.S. regions: southern; Pacific Northwest; desert at extreme altitudes. Spring April: You still have time to sow seeds indoors for transplanting next month. If your last-frost date falls around Memorial Day, sow seeds for all annuals, except fast-growing, tender plants (cosmos and zinnias, for example), by mid-April. If you live in warmer areas with milder winters, you can start sowing seeds of hardy annuals directly into the ground a couple weeks before the last frost date in their region. If it’s still cold in April where you live, wait until next month to direct-sow seeds. If you plant nothing else, sow sweet pea seeds as soon as the ground can be worked. Depending on your region, late April or May is the time to lay out beds and prepare the soil. Adjust the soil pH based on soil tests done in the fall. Amend the soil with a 2- or 3-inch layer of organic matter and a complete fertilizer. May: Early May is generally the best time to plant hardy annuals (seeds or transplants) in most areas — 10 to 14 days before the last frost is usually safe. Check local garden centers for ready-to-plant, cool-season annuals. Look for stocky, green plants when shopping at garden centers. Avoid plants with dead lower leaves and brown, overcrowded roots, as well as plants that are already flowering. Start transplanting tender annuals, such as impatiens, lobelia, and petunias, into the ground when frost danger has passed, the soil and air have warmed up, and the nights are no longer cold. June: Continue planting tender annuals, and remember that newly planted seeds and transplants are vulnerable. Gardeners in cold, mountainous areas often wait until June 10 to plant the most tender plants, such as impatiens. Water if June is dry. Mulch to conserve water and slow weed growth. Pull off or pinch back fading blooms of cool-season annuals to extend their season of color. July: Plants require extra water and nutrients to keep them at their peak in hot, dry weather. Container-bound plants, particularly, suffer from heat stress and usually need daily watering if they’re located in the sun. Container gardens quickly deplete soil nutrients; feed window boxes and pots with a liquid fertilizer every couple weeks. Continue feeding annuals to promote steady growth for the remainder of the summer. Stake taller plants. Deadhead flowers regularly. In hot climates, cool-season annuals probably have peaked, so pull them out. August: In northern regions where the growing season is 90 to 110 days long, late July through early August is the garden’s peak. Continue to deadhead, water, and weed. Containers still need to be fertilized. Tidy beds and containers by pulling out plants that have passed their peak. Harvest flowers for drying and enjoy fresh-cut bouquets Autumn to Winter September: Be ready with row covers or blankets if an early frost is predicted and you still have tender plants in bloom. Use pots of asters, calendulas, and flowering kale to replace frosted or dying annuals. Collect seed pods, dried flowers, and grasses to make arrangements. October: Pull out dead plants and add them to your compost pile. Take soil samples in the fall to know how to amend soil next spring. Use the results of the soil tests to gauge any adjustments that you need to make in soil pH and fertility. November through December: Sharpen, clean, and oil your tools. Keep a record of any extra seed you have. Store the extra seed in an airtight container in a cool location; add packets of silica gel to absorb any moisture in the container. Build your own window boxes or trellises for next year. Build a cold frame for growing and hardening off your transplants. Seek inspiration for next year’s garden in books and magazines.

The Southwest deserts encompass mild-winter climates of the low-elevation deserts of Arizona and California. (The mountains of Arizona and New Mexico, as well as west Texas, have a more typical cold-winter, summer-only season for growing annuals.) Glory time for annuals is late winter and early spring in low-desert Arizona, primarily around Phoenix and Tucson, and California’s Coachella Valley. This calendar starts in September to reflect the true beginning of the planting season: If you live in a temperate, high-altitude climate, follow the calendar recommendations for Northern gardeners. September: Prepare planting beds. Midmonth or later, set out nursery transplants for winter and spring bloom — maybe even by Christmas. Provide temporary shade during the hottest weather. Early in the month, you still have time to start annual flower seeds in flats or pots to transplant into the ground later in the fall. If summer annuals are still going strong, keep them watered thoroughly and fertilize every two or four weeks. October: Continue to set out annuals for blooms before the end of the year. Water thoroughly after planting and provide temporary shade during extra-hot spells. Sow seeds of low-spreading annuals to cover bare spots in bulb beds. If your timing is good, everything will bloom all at once. Start regular feeding a few weeks after planting annuals. November: You still have time to plant for winter and spring bloom. Cooler weather encourages a new crop of aphids, plus slugs and snails. December: You still have time to plant seedlings. Watch your soil for signs of dryness, and water as needed. January: After the holidays, nurseries stock up with blooming annuals in small pots. Shop for color that you can use right away in pots or in gaps in planting beds. Watch for aphids and take steps to control them. Pull or hoe seasonal weeds, or mulch beds with a layer of organic matter to smother weeds and weed seeds. February: Cool-season annuals are peaking this month in the low desert. Maintain top performance by removing dead flowers, watering thoroughly, and feeding regularly. Start seeds of warm-season annuals indoors to transplant into the garden in four to six weeks. Prepare beds for spring planting. March: In the low desert, transplant warm-season annuals. Pinch back at planting time and snip off flowers to encourage bushier growth. A few weeks after planting, fertilize young annuals and begin a regular (bi-weekly or monthly) fertilizing schedule. April: Plant heat-loving annuals, such as marigolds and zinnias. Adjust the frequency of sprinkler systems as the weather heats up. May: Spring flowers are winding down. Pull them out and replace them with heat-lovers. Pinch tips of young annuals for bushier growth. June: This is your last chance to plant for summer blooms. Make sure that you choose from among the true heat-lovers: globe amaranth, salvia, and the most reliable of all, vinca rosea. July and August: Water and mulch. You don’t do any planting at this time of year. Feed summer annuals regularly. Remove faded flowers.

Insect and disease killers that come from plant extracts are called botanical pesticides or botanicals. Although derived from natural sources, botanicals are not necessarily safer or less toxic to non-pest insects, humans, and animals than synthetically derived pesticides. In fact, most botanicals are broad-spectrum insecticides, which kill both good and bad bugs indiscriminately. Some botanicals cause allergic reactions in people, others are highly toxic to fish and animals, and some may even cause cancer. All pesticides — including botanicals — should be used only as a last resort after thoroughly reading the label on the package. The pesticides in this section are listed from least to most toxic to humans. Hot pepper wax and powder: The chemical capsaicin causes the heat in hot peppers and it's the active ingredient in these useful botanical products. In low doses, such as found in ready-to-use sprays and dusts, hot pepper wax repels most common insect pests from vegetables and ornamental plants. It doesn't cause the fruit or vegetables to become spicy hot, but instead stays on the surface of the plant where it remains effective for up to three weeks. Stronger commercial formulations kill insects as well as repel them. Hot pepper wax is even reportedly effective in repelling rabbits and tree squirrels. Neem: This pesticide is made from the seeds of the tropical neem tree, Azadirachta indica, and it comes in two forms — azadirachtin solution and neem oil. Unlike the other botanical insecticides in this section, neem does not poison insects outright. Instead, when insects eat the active ingredient, it interrupts their ability to develop and grow to their next life stage or lay eggs. It also deters insects from feeding and is effective against aphids, thrips, fungus gnats, caterpillars, beetles, leafminers, and others. Amazingly, plants can absorb neem so that any insects that feed on them may be killed or deterred from feeding. Neem breaks down in the presence of sun and soil within a week or so. To discourage insects from eating your plants, spray neem before you see a large infestation. The product Safer BioNeem contains azadirachtin solution. Neem oil, the other seed extract, also works against some plant leaf diseases, such as black spot on roses, powdery mildew, and rust diseases. Mix the syrupy solution with a soapy emulsifier to help it spread and stick to the plants. The neem oil products called Rose Defense and Fruit & Vegetable Defense (from Green Light) control insects, mites, and leaf diseases. Pyrethrins: These insecticidal compounds occur naturally in the flowers of some species of chrysanthemum plants. The toxins penetrate the insects' nervous system, quickly causing paralysis. In high enough doses or in combination with other pesticides, the insects die. Powerful synthetic compounds that imitate the natural chrysanthemum compounds are called pyrethroids. Pyrethroids are not approved for use in organic farms and gardens. Also avoid any pyrethrins that list "piperonyl butoxoid" on the label. This additive is not approved for organic use. The compound breaks down rapidly when exposed to sun and air and becomes less effective if stored for longer than one year. Many commercial products contain pyrethrins. Although relatively harmless to humans, pyrethrins are very highly toxic to fish and bees and moderately toxic to birds. It kills both beneficial and pest insects. To keep bees safe, spray pyrethrins in the evening after bees have returned to their hives for the night and avoid spraying blooming plants. Ryania: This pesticide comes from the tropical Ryania speciosa plant. Although it controls fruit and codling moths, corn earworm, European corn borer, and citrus thrips, it is also moderately toxic to humans, fish, and birds. It is very toxic to dogs. Seek other botanical pesticides before considering ryania. Sabadilla: Made from the seeds of a tropical plant, sabadilla is a powerful broad-spectrum insect killer. It's especially useful for controlling thrips, aphids, flea beetles, and tarnished plant bugs, but it also kills bees and other beneficial insects, and some people have severe allergic reactions to the chemical. Use it only as a last resort.
