Question: We have the drip system for watering all the plants and trees and palm trees. We are planning on having the fertilizer system added to the drip system. We were wondering if it is okay for the palms or do they need their own special fertilizer and at only certain times of the year.
Fertilizer injectors originally were intended to be used when growing all one kind of plant or plants with similar requirements. Not all plants have the same requirements.
When applying fertilizer to plants irrigated with drip, applying the fertilizer just under the emitters or using fertilizer stakes just a few inches off the emitters will push the fertilizer toward growing roots.
Foliar applications of fertilizers also work extremely well when applied during the growing season. Apply lightly.
