Fertilizing your Vegetable Garden (6208)

Some crops require more of some nutrients than others do. Root crops require less nitrogen fertilization than leafy crops. Corn is a heavy feeder and may require nitrogen fertilization every four weeks. A general rule of thumb is that nitrogen is for leafy top growth; phosphorus is for root and fruit production; and potassium is for cold hardiness, disease resistance, and general durability.

Proper use of nutrients can control the rate and character of plant growth. Nitrogen is the most critical nutrient in this regard.

Banding is when narrow bands of fertilizer are applied in furrows 2 to 3 inches from the garden seeds, and 1 to 2 inches deeper than the seeds or plants that are to be planted. For plants widely spaced, such as tomatoes, fertilizers can be placed in a circle around each plant. Place the bands 4 inches from the plant base.

Side dressing is when dry fertilizer is applied next to the plants after the plants are up and growing. Scatter fertilizer on both sides of the row, 6 to 8 inches from the plants. Rake it into the soil and water thoroughly.
