Bury smartpot ~halfway in the ground like some1 else mentioned.i need to water them everyday. I water untill I see run off. Then next day they are drooping. I give each pot 5-7 gallons of water. Plants are 6 feet tall topped 3 times and bushy. They are in 30 gallon smart pots. Is this normal? Temps are 90 degrees here always.
~or~
Buy larger smartpot, fill halfway with soil, lay 30gal inside +pack some soil around the 30gal.
Smartpots keep the roots from circling, but when roots get overpopulated they require more water.
Easiest to just bury it halfway in-ground so the water doesn't run-off immediately + roots can spread through the pot some.
You can find pics of some 12ft tall/12ft wide plants that are in ~150gal pots, for root-space comparison.
