August is the peak of summer making it one of the hottest months. While gardening in August, watering in the garden is a top priority. Using grey water or rainwater from a water butt is not only good for water conservation but also much better for plants.

What to do now
August is a busy time for gardeners. With the hot summer weather beating down on the garden, watering and maintenance are essential jobs. Watering potted plants and vegetable patches along with keeping ponds and bird baths topped up with water. Pruning, weeding and harvesting summer fruits and vegetables.
- Raise mower blades to help maintain moisture in the soil.
- Water lawns once a week to preserve water reserves.
- Lawns are prone to browning during summer but will green up again in Autumn.
- Mow summer meadows when the wildflowers have died back.
- Prepare areas which are due to be re-seeded or turfed in the Autumn.
Water lawns less frequently but deeply during august. If you live in an area with water restrictions, there are ways to keep your lawn healthy. Grass goes into a dormant state during times of drought and bounces back to life when the autumn rains come. If you don’t mind a slightly messy lawn, allow the grass to grow taller. Taller grass keeps the roots cool and helps to retain moisture in the soil. With this method, your lawn can be reduced to watering once a month.
