I was asked the other day about fertilize schedules for vegetables. There is plenty of fertilize information but not all in one place so I decided to create a vegetable fertilizer chart. Once the vegetables are planted, it is weed and feed (hopefully not feed the weeds) time until harvest.
Definitions
Side-dress – apply fertilizer 6 inches or so from center of plant. If one plant is involved, apply around entire plant. If a row of plants are involved, apply in a straight line on both sides of the row.
Vegetable Fertilizer Table
Vegetable | Dosage | Amt per plant | Notes |
New Asparagus |
10-10-10 | 4 cups per 100 sq ft | Early Spring |
Established Asparagus |
10-10-10 | 4 cups per 100 sq ft | After harvest (June or July) |
Carrots | 10-10-10 | 2 TBL per 10 feet | Side-dress when 3 inches tall |
Cucumbers | 10-10-10 | 1 TBL | Side-dress when plants vines are 10 inches long and after flowers begin to bloom. Do not dig down with a hoe more than 1 inch because this will damage the shallow feeder roots. The main roots go down 5 feet. |
Green Beans | 0-10-10 | Side-dress. Generally do not need fertilizer in decent soil. Do not give fertilizer that contains nitrogen. | |
Lettuce | 10-0-0 or 10-10-10 | 1 cup per 10 feet | Side-dress when 2 to 3 inches high. |
Peppers | 5-10-10 | 1 tsp | When blossoms show |
Potatoes | 10-10-10 | 2 LB per 100 sq ft | Side-dress when flowers appear |
Pumpkins | 10-20-10 10-10-10 |
2 TBL | While vine is growing. Once fruit is set. |
Radishes | 10-10-10 | 1 cup per 10 ft | Work fertilizer in soil just before planting. |
Spinach | 10-10-10 | 1 cup per 100 sq. feet | Side-dress when 2 to 3 inches tall. |
Sweet Corn | 10-10-10 | 9 LB per 1000 sq ft | Side-dress when plant is 1 foot tall and when tassels appear. |
Tomatoes | 10-10-10 | 1 TBL | Side-dress 8 inches from plant in a circle every 3 weeks |
Zucchini | 10-20-10 or 10-20-20 | 1 TBL | They need higher phosphorus than nitrogen. Side-dress fertilize when fruits form. |
2 cups = 1 pound fertilizer, TBL = tablespoon, LB = pound
