No garden bed? Start with a container.

Choose the crop before the pot

A small herb and a fruiting tomato do not need the same root space. Read the variety guidance and choose a container large enough for the mature plant. Compact or patio varieties can help, but the label is not a replacement for checking the actual dimensions and support needs.

Check drainage and weight

Use a container intended for growing plants, with open drainage holes and suitable material for food gardening. Consider its weight once wet, especially on a balcony or roof. Confirm structural capacity with the property owner or a qualified professional where relevant. Put the pot in position before filling it.

Use a container growing mix

A quality potting mix is designed to balance water retention and air in a container. Soil dug from the yard may compact and drain poorly in a pot. Check whether the mix already contains fertilizer before adding any more, and follow the crop and product guidance rather than combining multiple feeds.

Build a checking habit

Container moisture can change quickly in sun and wind. Check the growing mix rather than following an unchanging weekly schedule. Water as needed and allow excess to drain. A saucer that stays full can keep roots too wet. Keep the container where you can inspect leaves, tie supports, and harvest without moving it each time.
