Q.Coconut Coir & Citrus Trees
Hi. I have 4 citrus trees already potted and planted that are 4 yrs old.(Meyer lemon, clementines,key limes and yellow outside white inside grapefruits) I am interested in using the coconut coir as mulch to be on top of the current soil they have now. Which kind/type should I buy? Would this work out well for my trees so water stays in the trees longer? Look forward to hearing from you
