I'm going away just for 5 days in the beginning of May, not very hot around here at that time, basically in a couple of weeks. I got the GF up to speed on watering but it wouldn't surprise me if she misses a day or doesn't water anything till she comes home from work in the evening. I think everything can handle that except maybe the few things ( two JBPs) I have in pond baskets and one Chinese elm in a colander. They the only things I have right now that could dry out really quick. I set up this little deal where they could sit in water, only about an 1 1/2 inches on the bottom is in water. Could this harm the two JBPs and elm in just 5 days, It would give me piece of mind to know they're not drying out. I have them in it now for a test run but wasn't going to leave them in there for now.
