August can be a busy time on the allotment - there's lots of harvesting to do, including crops such as runner beans, potatoes and raspberries.


If you can't eat all of your crops at once, you can preserve them in a variety of ways and check out our selection of must-have kit for jam-making.

Depending on the weather, you may be doing lots of watering. In particularly dry periods, or during a drought or a hosepipe ban, you will need to think more carefully about water usage.

You might be going on holiday, and will need to prepare for time away from your plot.

Here are some allotment jobs for August.

Blossom end rot on tomato

Watch out for flea beetle on brassicas and related plants such as Swiss chard and rocket. The tiny holes they create don't affect the vigour of established plants but make the leaves less appealing to eat - cover plants with fleece. Also look out for blossom end rot on tomatoes, which is caused by irregular watering.
