watering mine in the winter is an all day job ....so an actual schedule works for me ....
during the winter months, while indoors they get watered once every 60 days ...in fact, have a watering coming up on April 19th
Once outdoors ....and night temps are steady upper 50's .... and day time highs in the 70's to 80's, plants get watered about every 10 to 14 days ....when day time temps hit the 90's then plants get watered once every 7 days .....
when day time temps hit the 100's then plants get watered once every 3 to 5 days
water in the morning ......avoid mid day or late in the day
any amount of rainfall ...is considerd a watering day (and a bonus because it is free)
