How Do Droughts Affect Trees?

In nature’s symphony, trees are like unsung heroes, standing tall and weaving their branches together in the web of life. But when droughts come, these majestic beings face a big problem that can affect entire ecosystems. Droughts seriously threaten the survival and well-being of trees.

Understanding Droughts and Why They Happen

Droughts can be meteorological, agricultural, or hydrological, depending on what causes the lack of water. Different things contribute to droughts, like climate change, changes in rainfall patterns, and shifts in temperature. These factors are connected and affect how often droughts happen, as well as how severe they are.

How Droughts Affect Trees on the Inside

Trees rely on a complex system of roots, stems, and leaves to transport water. During a drought, trees go through water stress, which means they change in important ways. The little openings on leaves called stomata, which help with breathing, close up to keep water from escaping.

However, this closing also stops the tree from taking in carbon dioxide, which is needed for photosynthesis and growth. Because of the lack of water, trees have to prioritize their essential functions, and this can change the way they grow and develop. If droughts go on for a long time, trees can even die because they can’t get enough water to survive.

Changes to the Look and Structure of Trees

As stated, droughts can cause significant changes in how trees look and grow. As water becomes scarce, trees might change their leaves and the shape of their canopy. Leaves can become smaller, thicker, or change color because of the lack of water. Droughts can also affect the density of the wood and make changes to the tree’s structure. That’s why it’s important to water your trees during a drought if possible.

Dangers of Xylem Embolism and Hydraulic Failure

During a drought, trees face a big risk called xylem embolism. This happens when air bubbles get in the pathways that carry water through the tree. The lack of water and increased tension can make these pathways break, which is called hydraulic failure.

When this happens, trees can’t transport water and nutrients properly, which makes the effects of the drought even worse. It’s hard for trees to recover from this kind of damage, and repeated droughts can make them weaker and less able to survive.

Harm to the Bark and Roots

Droughts make trees weak, which means their bark and roots are more likely to get damaged. When trees lose water, their tissues shrink and the bark may crack and split. This kind of damage creates openings that pests and diseases can use to attack the tree. Shallow roots are also at risk of dying, and this affects the tree’s ability to be stable in the ground and get enough water and nutrients.

Water Your Trees!

When you water your tree, make sure to give it a good soak so that the water reaches the roots. For house plants, water the pot until you see water coming out of the holes at the bottom. This way, the entire root system gets water. You can also use self-watering tools like watering spikes or pots that release water slowly. These methods keep the soil moist without overwatering.

For outdoor trees, in addition to watering, you can put a layer of organic mulch, like wood chips or straw, around the base of your tree or plants. This helps to keep the soil moist by stopping water from evaporating, keeps the roots cool, and prevents weeds. You can also try grouping plants with similar water needs together. This creates a small area with the right conditions for them, so you can water all of them together without over or under watering any.

Preventing Future Problems

Make sure the containers you use for your indoor plants have holes at the bottom for water to drain out. This helps prevent water from building up and causing root rot. Stick your finger about an inch into the soil to check if it’s dry before watering your plant. If the soil still feels moist, it’s best to wait before watering again.
