My name is Josh and this is my first post. I recently bought a patio pickers box from Lowes and put it out on the patio of my third floor apartment. I planted six vegetable plants in this unit with organic potting mix. The box has a water tube that I pour water into every other day till it runs out of the overflow holes near the bottom along the sides. The patio seems to get sun in the afternoon towards the hotter part of the day.
My question is, do I need to put any dolomite or additional fertilizer in the soil? I want to stay completely organic so I am not sure if dolomite would be breaking this rule or not. Also, I was told to start watering daily when they get closer to full size and begin to produce veggies. I am new to this whole gardening thing so take it easy on me
