Where to Put Your Vegetable Garden
When deciding where to plant your vegetable garden, assess sun exposure, soil quality, and water access. Choosing a garden site that's best for growing vegetables is based on good old common sense, as these tips reveal:
Keep it close: Plant your garden where you'll walk by it daily so that you remember to care for it. Also, a vegetable garden is a place people like to gather, so keep it close to a pathway.
Make it easy to access: If you need to bring in soil, compost, mulch, or wood by truck or car, make sure your garden can be easily reached by a vehicle.
Have a water source close by: Hauling hose around to water the garden will cause extra work and frustration.
Keep it flat. You can garden on a slight slope, and, in fact, a south-facing one is ideal since it warms up faster in spring. However, too severe a slope could lead to erosion problems.

A sample yard with possible (and impossible) sites for a vegetable garden.
If you're a first-time gardener, 100 square feet is plenty of garden to take care of; start small and build on your success. However, if you want to produce food for storing and sharing, a 20-foot-x-30-foot plot (600 square feet total) is a great size.
Fruiting vegetables, such as tomatoes, peppers, beans, squash, melons, cucumbers, and eggplant, need at least 6 hours of direct sun a day for good yields. The amount of sun doesn't have to be continuous though. You can have 3 hours in the morning with some shade midday and then 3 more hours in the late afternoon.
If your little piece of heaven gets less than 6 hours of sun, you have some options:
Greens, such as lettuce, arugula, bok choy, and spinach, produce reasonably well in a partially shaded location where the sun shines directly on the plants for 3 to 4 hours a day.
Root crops, such as carrots, potatoes, and beets, need more light than leafy vegetables, but they may do well getting only 4 to 6 hours of sun a day.
A site that's sunny in midsummer may later be shaded by trees, buildings, and the longer shadows of late fall and early spring. If you live in a mild-winter climate, such as parts of the southeastern and southwestern United States where it's possible to grow vegetables nearly year-round, choose a spot that's sunny in winter as well as in summer.
You can have multiple vegetable garden plots around your yard matching the conditions with the vegetables you're growing. If your only sunny spot is a strip of ground along the front of the house, plant a row of peppers and tomatoes. If you have a perfect location near a backdoor, but it only gets morning sun, plant lettuce and greens in that plot.

Gardening Glossary
annuals
Plants that complete their entire life cycle within one growing season. The plant germinates from seed, grows and blooms, and then produces seed and dies.

Gardening Glossary
biennials
A plant that take two growing seasons to complete its life cycle. It germinates and grows leaves and stems in the first year; produces flowers and fruit (seed) in the second, and then dies.

Gardening Glossary
bolt

Gardening Glossary
cold frame
A wooden or concrete block box in which you can grow plants or hold dormant during the cold winter months.

Gardening Glossary
harden off
The process of acclimating plants grown indoors gradually to the brighter light and cooler temperatures of the outside world.

Gardening Glossary
hardiness
The ability of a plant to survive is called its hardiness.

Gardening Glossary
humus
A stable end product of organic-matter decomposition that's believed to increase microbial activity in soil, improve soil structure, and enhance the root development of plants.

Gardening Glossary
Bacillus thuringiensis Bt
An effective bacteria that attacks only the larvae of caterpillar family insects. It is safe to other insects, animals, and humans.

Gardening Glossary
macronutrients
Mineral nutrients that plants need in the largest quantities: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.

Gardening Glossary
mulch
Organic or inorganic material placed over the surface of soil, usually directly over the root zone of growing plants. Used to conserve moisture, kill weed seedlings, modify soil temperature, provide attractive covering to garden beds.

Gardening Glossary
organic matter
Once-living stuff like compost, sawdust, animal manure, ground bark, grass clippings, and leaf mold (composted tree leaves). Used to enrich soil and improve soil texture.

Gardening Glossary
perennials
Any plant with a life cycle of three or more years. Herbaceous (non-woody) perennials include flowering plants and herbs, mainly. Woody perennials include trees and shrubs. Longevity depends on the plant and growing conditions.

Gardening Glossary
pH
The measure of soil's acidity. Soil with low pH means it's too acidic; soil with high pH means it's alkaline. Most plants grow best in soil with a pH value between 6.5 and 7.2. Neutral soils measure 7.

Gardening Glossary
photosynthesis
The process through which plants take nutrients from the air and from the water in the soil to produce sugars that fuels the plant's growth.

Gardening Glossary
primary nutrients
Nitrogen, phosphorous, and potassium are the three nutrients plants need in the largest quantities.

Gardening Glossary
root crops
Plants with edible underground roots such as onions, carrots, beets, potatoes, turnips. Most root crops are cold-weather crops.

Gardening Glossary
self-blanching
A type of cauliflower with leaves that naturally curl over the head and exclude light. Requires cool temperatures for leaves to curl effectively.

Gardening Glossary
sets

Gardening Glossary
side-dressing
The act of adding a small amount of fertilizer around or "on the side" of plants after they're growing.

Gardening Glossary
succession planting
Planting small, 2-to-4-foot patches of plants every two weeks throughout the growing season so that you can harvest a crop over an extended period of time.

Gardening Glossary
thinning
The act of cutting the least robust seedlings in your garden to give the healthier plants more room to grow.

Gardening Glossary
vining crops
Crops that grow on vines, such as cucumbers, melons, pumpkins, and winter squash. They usually require support (staking, trellising, etc.) to keep them off the ground.
