The amount of fertilizer to apply to a garden depends on the natural fertility of the soil, the amount of organic matter present, the type of fertilizer used, and the crop being grown. The best way to determine fertilizer needs is to have the soil tested. Soil testing is available through your local Extension agent, through private labs, and with soil test kits which can be purchased from garden shops and catalogs.

Mulching is a practice adaptable to nearly all home gardens. To mulch is simply to cover the soil around plants with a protective material, organic or inorganic.

This publication will describe the common types of beans grown in Virginia's home gardens and how to grow each.

Sweet corn varieties differ significantly in time to maturity and in quality; yellow, white, bicolor, standard, and extra-sweet varieties are available. Most varieties planted are hybrids, which have been bred for greater vigor and higher yields. A continuous harvest can be planned by planting early, mid-season, and late-season varieties or by making successive plantings of the same variety every two weeks or when the last planting has three to four leaves (corn sown in early spring will take longer because of cool temperatures).

This publication provides guidance on growing cucumbers, melons, and squash in home gardens. It describes key cultivar types and outlines planting, spacing, fertilization, trellising, and pollination needs. Melons and squash are detailed by environmental preferences, cultural practices, and growth habits, including recommendations for black plastic mulch, transplanting, and managing pollinator activity. Common diseases, insect pests, and cultural problems are identified, along with strategies to reduce damage. Harvesting guidelines, storage conditions, and expected yields are included to help gardeners achieve high‑quality fruit across these warm‑season crops.

This publication provides comprehensive guidance on growing leafy green vegetables, including lettuce, spinach, cooking greens, and chard. It outlines environmental preferences, planting methods, spacing, and fertilization needs for each crop. Cultural practices emphasize cool‑season production, succession planting, proper watering, and mulching to maintain soil moisture and reduce disease. The guide details characteristics and harvest stages for crisphead, butterhead, romaine, and leaf lettuces, as well as strategies to prevent bolting and bitterness. Common diseases, insect pests, and cultural disorders are identified, along with recommended storage conditions and expected yields, helping gardeners achieve high‑quality, continuous harvests.

Onions are often grouped according to taste. The two main types of onions are strong flavored (American) and mild (often called European). Each has three distinct colors, yellow, white, and red. In general, the American onion produces bulbs of smaller size, denser texture, stronger flavor, and better keeping quality than European types. Globe varieties tend to keep longer in storage.

Tomatoes are valuable garden plants in that they require relatively little space for large production. Each standard tomato plant, properly cared for, yields 10 to 15 pounds or more of fruit.Diane Relf, Retired Extension Specialist, Horticulture, Virginia Tech Alan McDaniel, Extension Specialist, Horticulture, Virginia Tech Ronald Morse, Former Associate Professor, Horticulture, Virginia Tech Reviewed by John Freeborn, Assistant Master Gardener Coordinator, Horticulture, Virginia Tech
