How to look

after your tree

Once you’ve planted your tree, it’s very important to continue to look after it, especially as the UK’s weather patterns become more erratic.

Remember, the first five years of a tree’s life are crucial for its survival. Make sure you monitor your tree regularly, checking that the leaves look healthy in the spring and summer. And that the ground is mulched and watered regularly.

With our changing climate our weather is becoming less predictable. As weather patterns change, so too does the care advice. Getting to know your tree and what you expect from it is key.

Regular watering

Young trees need to be well watered for at least the first three years. Unless there has been heavy rainfall, this will mean watering weekly from April to the end of September. And even more regularly if it is very dry.

The best time to water a tree is early in the morning or in the evening when the sun is not as strong, so the water can soak into the soil without evaporating too quickly.

The amount of water depends on the size and type of tree. Generally, trees need one full watering can or five minutes with a hose per 2.5cm of trunk diameter at knee height.

Water your tree slowly and deeply, directing the water towards the base of the tree. Make sure that the water soaks into the soil to a depth of at least six inches. This encourages the tree’s roots to grow deeper, making it more resistant to drought. Avoid spraying the leaves as this can lead to fungal diseases.

Mulching and pruning

Keep your tree well mulched. Mulch is a loose layer of material added on top of the soil. It’s great for improving the soil, adding nutrients, keeping the weeds down and reducing the need for watering. Most organic matter will work well as a mulch, such as bark chippings, well-rotted horse manure or grass clippings.

You may need to add a layer of mulch several times in the first few years.

After your tree has been able to grow for a few years, it will need pruning to give it shape for the future. Formative pruning is also important for fruit trees to increase the yield of fruit. Specialist information and courses are available to teach you how to prune trees.
