So I'm putting a few of my ladies in 15 gallon fabric pots outdoors, and I'm having a hard time telling when they are fully saturated. Do you water till it leaks out the sides, till it pours out? Do you wait for the droop to water again? This is new territory for me and I'm second guessing my decision to use fabric pots all together. I know many love them, so I'm hoping for some guidance.
