    When your tree was young, you followed a strict watering schedule. However, as it matured, you more than likely abandoned that schedule. After all, mature trees can survive with the water they get when it rains, right? Not really.

    Do mature trees need watering? While the watering needs of fully grown trees are different, they still require deep watering from time to time.

    Read on to learn why mature trees need watering and how often you should water them.

    How To Tell Your Mature Tree Needs Water

    Mature trees have roots deep enough to survive Fairfax’s dry seasons. Sometimes, though, these seasons can go on for a bit too long. If it’s been months since it last rained, your tree will start crying out for supplemental moisture.

    Here’s how you can tell when to water your mature tree.

    Leaf Discoloration

    One of the tell-tale signs to look for is changes in leaf color. Your tree’s leaves could start browning at the edges and tips. They might also wilt or curl.

    Premature Leaf Drop

    In a bid to conserve water, your tree could shed its leaves prematurely. While such a sight can leave you concerned, it might be a good idea to try watering the tree before getting professional tree services in Fairfax, VA.

    Drought Stress

    Check for symptoms of drought stress, such as smaller leaves and slow leaf growth.

    Lack of Soil Moisture

    Sometimes, the soil your tree is growing in could tell you all you need to know. Is it dry, dusty, or cracked? If so, it’s time to water the tree.

    What To Keep in Mind When Watering Your Mature Tree

    Do mature trees need watering? Absolutely! To be sure, mature trees are self-sufficient, but periodical deep watering helps support their continued health.

    However, certified arborists recommend keeping a few things in mind if you are to properly water your mature trees.

    How Often To Water

    Your goal should be to encourage your tree’s roots to extend deep into the soil. Instead of giving it several light waterings, it’s better to give it a deep soak once a week. Doing so allows the water to seep into the soil, encouraging the tree’s roots to grow deeper down.

    Where To Water

    When watering, always aim at the perimeter of your tree’s canopy. Watering too close to the trunk doesn’t hydrate the tree as much as you think. In fact, it leaves your tree vulnerable to rot and fungal growth.

    Consider Mulching

    Place a three- or four-inch layer of mulch about an inch from the tree’s trunk. This will help keep your tree hydrated through long periods of drought.
