I think my banana in my Sonroom is about ready to put out the fruit spike. Should I fertilize it now, or not, when I water?
I have no experience with banana trees. However, in general, when the plant begins to put on buds/flower it is time to fertilize. Then again once the actual fruit is well on the way. Generally, I get the Fertilizer that mixes with water for this.
I also sometimes when growing in pots, sprinkle the slow release fertilizer beads around the pot. Hope this helps.
