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.
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|
|10-10-10||4 cups per 100 sq ft||Early Spring|
|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|
|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
