Here are some gardening tasks to do in the UK during the month of August:

1. Watering: August can be a hot and dry month, so it’s important to water your plants regularly, especially newly planted ones. Watering in the early morning or late evening can help reduce water loss through evaporation.
2. Deadheading: Deadheading, or removing spent flowers, can encourage plants to produce more blooms and extend the flowering season.
3. Pruning: Prune back any summer-flowering shrubs or trees that have finished blooming. This will help maintain their shape and promote healthy growth.
4. Harvesting: Many fruits and vegetables will still be ready for harvesting in August, including tomatoes, courgettes, and cucumbers. Regular harvesting can encourage the plants to produce more.
5. Feeding: Applying a balanced fertilizer to your plants can help promote healthy growth and encourage blooming.
6. Sowing: August is a good time to sow seeds for autumn and winter crops, such as lettuce, spinach, and kale.
7. Planning: Start planning your autumn and winter garden, including ordering seeds, bulbs, and plants.
8. Weeding: Keep on top of weeds by regularly removing them from your garden beds and borders.

By completing these tasks in August, you can help ensure that your garden stays healthy and productive throughout the remainder of the growing season.
