My wife and I will be going on an extended trip at the end of May for 5+ weeks. We have 2 indoor Saguaro cacti and a Golden Barrel ranging from 5" to 16" high. I purchased the 16" Saguaro in a local pharmacy in 1985 in a two inch pot when I moved out here.
Could someone tell us if I soak them before we leave will they survive at a southern exposure window without watering or is there some sort of temporary irrigation I can set up? I generally water them once a week depending on the soil. They were re-potted last year in Miracle Grow Moisture Control Potting Mix. Any suggestions would be greatly appreciated. Thank you.
