Fruit, Vegetable, and Herb Care

April

Young lettuce AprilPlant small transplants of asparagus, early potatoes, lettuce, radish, mustard, onions, peas, rhubarb, spinach, turnips, cauliflower, carrots, and all other cool-season crops as weather permits. Plant midseason potatoes in mid-April.

Plant strawberries and pinch off first-year flowers to develop strong root systems.

Later in the month, begin to harden off warm-season vegetable and flower transplants in a cold frame, or bring flats of small transplants outside to sunny, protected areas — but bring them back in at night.

If necessary, spray fruit trees with dormant oil for insect control. If apple scab was a problem last year with crabapple or apple trees, be ready to start spraying with an approved fungicide as soon as the leaf buds begin to swell and open. Spray routine will last until two weeks after petal drop. Wet weather will only aggravate the problem. Call Plant Information for exact timing and recommended fungicides.Fertilize fruit trees and brambles. If growing fruit trees for their fruit yields, begin a spray program for insects and disease. Call Plant Information for exact timing and approved chemicals.
