What is a drought?

A drought is a prolonged period of abnormally low rainfall, resulting in a shortage of water supply for both human and natural systems. It can lead to a deficiency in surface water, groundwater, and soil moisture, causing severe impacts on agriculture, ecosystems, and communities. Droughts can occur on various scales, ranging from local and regional areas.

When do droughts occur?

Droughts can occur at different times depending on the region and climate. In some areas, droughts are most common during certain seasons. It's important to note that the timing and duration of droughts can vary widely, and other factors such as climate patterns, geographical location, and weather conditions also influence when droughts are most common in specific areas. Droughts are not very common in central Mississippi, but have been occurring the over the last few weeks.

Which trees are most susceptible to droughts?

Some trees that are most susceptible to droughts include Dawn Redwood, Ash trees, Walnut trees, Ginkgo Biloba, Jacaranda, and Willows. It is worth noting that while these trees may be more susceptible to drought, there are also many factors that can affect a tree's ability to withstand drought conditions, such as soil type, location, and overall health of the tree.

How do droughts impact trees?

Drought can have various effects on trees, and the impact may differ depending on the tree species. Severe drought can potentially have a long-term impact on trees, even after the drought has ended. While some trees may survive and recover, others may experience lingering stress for years, even when soil moisture returns. Drought can indeed cause tree death, especially if the drought is severe and prolonged. During a drought, the low soil moisture content limits the tree's access to water, making it challenging for them to carry out vital processes.

What can I do?

• Determine moisture levels: Trees have deeper and more extensive root systems than turfgrass, so they require water to be supplied slowly and for longer durations compared to other plants. To conserve water and maintain healthy trees, wait until just before water stress occurs before watering.

• Mulch: Apply a layer of organic mulch, such as wood chips or tree bark, around the base of the tree. The mulch should be 3-4 inches deep and extend a sufficient distance, even up to the drip line of the tree. Keep the mulch 3-6 inches away from the trunk to prevent moisture buildup and potential rotting.

• Weed control: Control grass and weed growth around the tree by regularly mowing and cultivating the soil to a depth of 1 inch to prevent competition for water.

• Pruning: Prune dead or dying branches to reduce stress on the tree and promote its overall health. However, it is generally recommended to avoid extensive pruning during drought conditions as it may further stress the tree.
