I am repotting my plants on the south facing front porch. I live in SW FL My fiddle fig has roots coming out of the bottom of the pot. I got this or at Target and it has an attached tray for water, but I want to change it to one I can water till it runs out of the bottom and when finished put it back on the porch in a drip tray. Do I need to go up in diameter or height of the planter? TIA!
