We all enjoy the summer days when we can stay outside from dawn until dusk, relishing in the summer sun. But with the summer sun can come dry, drought-like conditions. Drought causes extreme stress on trees with effects that can last throughout the rest of the year. It is important to make sure you provide proper tree service throughout droughts for reasons of both health and beauty. Especially in areas that focus on preserving the natural environment, like North Oaks, Minnesota. Find out more about how to prevent tree stress during dry periods using these tips.
It is important to understand the negative effects drought has on trees. One of the most obvious ways to spot drought is by observing the leaves. Deciduous trees, or shade trees that are experiencing stress from drought will have leaves that are wilted or have rolled edges. They may also fall from the tree prematurely or grow to a smaller size than usual. Conifer trees, such as pines or spruces, will have needles that are yellow or brown. Pest infestation can also become an issue for trees struggling through drought, as the trees have a weaker defense system to fight off attacks.
The amount of water required for a tree varies based on age and size. During a drought, trees should be watered every 7-10 days, between dusk and dawn. This better ensures the absorption of the moisture to the roots of the tree. Mature trees typically need watering less often, but during a drought, watering may be necessary to manage the moisture content. To properly reach the root system, water the areas covered by the tree canopy. Some coniferous trees will need watering beyond that area, so be sure to examine the special attention required by your trees.
Watering techniques can include drip irrigation (a system that drips water to the roots through a tubing series), soaker hoses (a hose that lays flat and emits water throughout its length, typically set to circle the tree’s trunk) and watering hoses with various attachments. For trees up to 7” in diameter, drip irrigation or a soft spray hose attachment are recommended. Trees that are 8-15” should be watered using a soaker hose or soft spray hose attachment. Larger trees best receive water through a hose with a flow attachment greater than that of a soft spray. Soil needles can also be used, regardless of the size of the tree.
