I use an app called Errands. All my orchids are listed in it by a table # and colored tag, i.e. (# 4 RED). So when I go away, I have a neighbor come for about an hour each day to water plants due that day. I either put what’s due each day in a spread sheet for the whole trip or in a word doc by day. She pulls them by table #, so she knows where to put them back and uses tap water. I paid her at first, now she enjoys it and does it for free. I give her an orchid gift every now and then.What do you all do for watering when you are away for extended times? I am planning a once in a life time family vacation that will last about 4 weeks. But I water every week and anything beyond that concerns me.
