Hello :) I bought a Best Boy tomato and put it in a big pot and put a cage to support it. Buuuttttt.....I didn't burry some of the stem (to help strengthen it). Is this ok? Should I get some potting mix and make a little hill around the base of the plant or just leave it? In about a week and a half I would say it's doubled in size so it's doing well. I also pinched some of the leaves and stems growing at the base of the plant. Thank you! :)
