We all know it needs some love and care at the planting stage and even some water for at least the first year. Once it is established and strong enough to look after itself, we generally come back to care for it only when it is starting to look a little poorly. But this is when a little ongoing maintenance can make the tree flourish, setting it up for decades to come.
One of the most important things for young trees is to reduce the competition around the roots for moisture and nutrients. This is particularly true for trees planted in grassed areas, as grass is a great competitor. Any weeds or grass around the tree should ideally be removed to at least 1m away from the trunk, and as an added benefit a biodegradable weed mat can be applied. They are made of natural materials and break down over a couple of years. The addition of a slow release fertiliser, often sold in pelleted form, will also help your plant get established quickly.
But don’t stop there — apply a good, thick layer of mulch such as wood or bark chips to help maintain moisture and suppress weeds for the future.
