Even in this drought I only watered them once a week, sometimes the ones on the palms don't get watered for weeks. They don't seem to care. Now I have to say that the one in the lathe house that gets a little more attention has 4 spikes that are 5' , the one in the back yard that gets a little more attention has 1 spike that is about 4' and the one in the front yard that hardly ever gets attention has 1 spike 3'. By attention I mean that they see fertilizer and a little more water.
