Before you buy anything
Almost every failed home garden fails for one of three reasons: the plant was wrong for the light, the pot did not drain, or the watering was frequent and shallow instead of occasional and deep. The six steps below are ordered to head off exactly those three, which is why reading your space comes before buying a single pot.
Give yourself a season. A balcony garden becomes convincing in about ten weeks — enough for greens to be cut twice, a chilli to set fruit and a tulsi to fill out. Start with five pots you can look after well rather than fifteen you cannot.
What it costs
A working five-pot kitchen garden — pots, coco peat, compost, coarse sand, seed and a watering can — comes to less than a month of buying the same herbs. After the first setup, the running cost is compost every six weeks and seed once a season; cuttings and saved seed bring even that down.
When something goes wrong
Yellow leaves usually mean too much water, not too little. Leggy, stretched growth means too little light. Holes and sticky leaves mean pests — deal with them the day you see them, with a jet of water first and a weekly neem spray after. The plant care questions further down this page cover the problems we are asked about most.
