HALLOOOOOO! Ti like fertilizer and mulch - they can withstand periods of dry. One thing they detest is flouride and other chemicals in 'city water'...so if you can save rainwater, all the better....or let the water sit out for 24/48 hours for the chemicals to flash off.....
I don't think you can water themtoo much....but they do respond well to fertilizer...and foliar is great!!!!
Hope this helps. Thanks for the call....
