If you don’t have a garden, you almost certainly have windows. These are great places to grow things you can eat – and they can behave a little like greenhouses do too.
Depending on the size of your window ledge, you may be able to place some trays or troughs along the ledge, or perhaps affix some brackets with a trough or trays just underneath – as long as there is nothing like a radiator or similar in the way.
Do a search on ‘window gardens’, ‘what to grow in a window garden’, ‘setting up a window garden’, to get some ideas of what will be involved.
If your window box is outdoors, you may need to make sure that it is secured against wind or bad weather.
If the only windows you have available look abut a public pathway or road, growing food outside may not be the best plan for you – as your produce could disappear overnight when others who might be desperate can see – and easily reach – what you have grown.
