From proper cooling to mulching, here are some tips to protect your trees in the hot summer months.

1. Add a fresh layer of mulch

Spring is the ideal time to add a fresh layer of mulch for your trees and plants. However, if you didn’t get around to it then, make sure to tick this off in summer. Or, if you added mulch in spring, the hotter months may be a good time to do a quick check and add a top-up where needed. It is important to ensure that your mulch layer is not too thick – it should be just enough to prevent invasive pests and germs. 5-10cm is a good layer height.

Mulching has multiple benefits. It cuts down weed growth so your trees don’t have to fight for nutrients. It also helps stabilise soil temperature, and most importantly for summer, it helps retain the moisture.

2. Water your trees

Water is essential for trees (or any plant) to prosper. During the hotter months, especially when it is drier, watering trees is essential. Young or newly planted trees are the ones that benefit most from this activity.

When watering trees, deeper, less-frequent – perhaps once a week – watering is sufficient.

3. Inspect trees and tree trunks often

Drooping trees and wilting or yellowing leaves are the signs that your trees are not coping well with the heat and require special attention. This is particularly true for younger trees.

Whilst not summer related, make sure to check tree trunks, especially if they are rooted on well-trodden paths. It pays to create some sort of barrier for such trees so as to protect them from further damage, particularly by animals.

4. Fertilise

Make sure your trees have plenty of nutrition to support growth and fight off pests and diseases, all while surviving the stress of the hot summer sun. Trees growing in urban environments, including new developments, benefit from additional fertilisation.

Aerating the soil by making holes at regular intervals will not only improve absorption of the fertiliser but will also increase the flow of air and water.

5. Tree pruning

Tree pruning is best done during the dormant months. Summer is not ideal for active pruning of trees. However, if you see dead, diseased or damaged branches, they should be pruned for safety reasons as soon as possible, regardless of the season.
