For many plants, fertilizing this time of year can have negative impacts. For example, late-summer fertilizer applications to trees and shrubs encourage new growth that may not harden-off prior to a freeze. Of course, there are always exceptions. The following plants benefit from late-summer feeding.
Fruits and Vegetables
- Blackberries benefit from a second application of fertilizer after harvest.
- Fertilize June-bearing strawberries late summer following renovation. Feed ever-bearing strawberries in small applications throughout the summer.
- Continue fertilizing vegetable crops as needed
- Continue fertilizing warm-season grasses as needed until mid-September.
