We have some tips here on looking after your garden in a heatwave:
Most importantly, water your garden at the right time of day. The best time is first thing in the morning but if this isn’t possible then opt for early evening. Try to avoid watering in the middle of the day. Watering in the morning helps to prevent against your plant leaves being scalded in the hot sun. Potted plants will need even more water and may need to be watered twice a day during extreme heat, once in the morning and once in the evening. Aim the water for the soil around the plants and not the leaves themselves. Any new plants should be given particular attention to help them establish. A water butt is a great way to use water efficiently in your garden so if you don’t have one already it is definitely something to consider.
Adding bark or compost to your beds will provide a damp layer of insulation to lock in moisture and help to prevent soil from drying out.
If possible move your pots into the shade. You can also buy shade covers for your plants and beds from garden centres. When putting these down take care that they do block the sunlight but that they don’t reduce aeration.
Don’t cut your lawn quite as short during the really hot weather as the longer grass casts shadows that help the soil to retain moisture. Keep it around 3”. During a heatwave is not the time to add fertilisers to your lawn as the roots aren’t as able to absorb the nutrients as well so wait until the weather cools down to do this.
Leave your soil alone as disturbing it will only get rid of moisture.
Finally, look after yourself too. Grab a chair, a cold drink and enjoy the summer in your garden!
