Caring For Your Trees In A Drought (St. Louis, MO)
As a homeowner, you probably have a strong desire to maintain healthy and vibrant trees on your property. They are after all one of your property’s greatest assets. If you are in the St. Louis metro area like we are you are probably used to experiencing the hot and arid conditions that summertime often brings. Drought stress during the height of summer can pose a significant threat to the well-being of your trees. In this post, we will provide you with some tips and best practices you can utilize in caring for your trees to give them their best chance to weather the drought stress they often experience in our region.
Tips & Best Practices to Implement:
Mulching: Mulching is a fundamental practice for conserving soil moisture and protecting tree roots from extreme temperatures. Apply a layer of organic mulch, such as wood chips or shredded bark, around the base of your trees, extending it at least 3 to 4 feet from the trunk. This helps to retain moisture, regulate soil temperature, and suppress weed growth. Keep the mulch layer approximately 2 to 4 inches thick, ensuring it does not cover the root flare (base of the trunk where it meets the ground).
Watering Deeply: Watering deeply is crucial for promoting healthy root development and resilience to drought conditions. Provide slow, deep watering to ensure the water reaches the root zone. Use a soaker hose or drip irrigation system placed within the drip line (the entire ground area directly underneath the crown, or canopy of the tree), where the majority of the active roots are located. Water the tree thoroughly, allowing the soil to absorb moisture and minimize runoff.
Watering Frequency: Establish a watering schedule that takes into account the specific needs of your trees and the prevailing weather conditions. As a general rule, deep watering once a week is often sufficient for established trees during periods of normal rainfall. However, during prolonged dry spells or drought conditions, more frequent watering may be necessary. Monitor the soil moisture level and adjust the watering frequency accordingly.
Timing is Key: Watering at the right time of day is crucial for maximizing water absorption and minimizing evaporation. Water your trees early in the morning or late in the evening when temperatures are cooler and evaporation rates are lower. This allows the soil to absorb moisture more effectively and reduces water loss due to evaporation. Avoid watering during the hottest parts of the day.
Proper Irrigation Techniques: Use efficient irrigation techniques to ensure water reaches the tree's root zone effectively. Avoid overhead sprinklers, as they can result in significant water loss through evaporation. Instead, use methods such as soaker hoses, drip irrigation, or targeted watering with a hose to deliver water directly to the soil around the tree's base.
Monitor Soil Moisture: Regularly monitor the soil moisture level around your trees. Use a soil moisture probe, or simply insert a screwdriver into the ground near the root zone. If the soil feels dry to a depth of 6 inches or more, it's an indication that watering is needed. Adjust your watering practices based on the moisture level, ensuring you provide adequate moisture without overwatering.
Proper watering practices are essential for protecting your trees from drought stress and maintaining their health in the St. Louis area. By implementing these tips and best practices, including mulching, deep watering, monitoring soil moisture, timing, and employing efficient irrigation techniques, you can significantly reduce the impact of drought on your trees. Remember, healthy and resilient trees not only enhance the beauty of your property but also provide numerous environmental benefits for you and your community.
