How to Water Trees in 100+ Heat in The Summer Time

How Often Should I Water Trees in 100+ Heat?

If you are living in most of the areas of the U.S. this time of year, like myself you are experiencing brutal heat during July and August.  I think this year is worse than I can remember, but could just be I'm getting old and not as resilient. LOL.  I am getting a lot of calls regarding watering trees, so thought I would put something together that might help.  And while I recognize there's a huge difference between Maine and Arizona...cactus

like trees need water to survive, perhaps just not as much!  Also, Liquid Soil Aerator is one of the best things you can do to help prepare your trees to survive the heat and drought.  At the end of this article I have included more info about the subject and here's my two cents!

As temperatures soar above 100 degrees, it's essential to take extra care of your trees. Proper watering is crucial to ensure their health and survival during extreme heat. But how often should you water your trees in such scorching conditions? In this blog post, we'll explore the factors that influence tree water requirements and provide you with six key tips to help you determine the right watering frequency.

Factors Influencing Tree Watering Needs

Before delving into how often you should water your trees in 100+ heat, it's essential to understand the factors that influence their water requirements. These factors include:

  1. Tree Species: Different tree species have varying water needs. Some trees are more drought-tolerant and require less frequent watering, while others need a consistently moist environment.

  2. Tree Age and Size: Younger trees typically require more frequent watering than mature ones. Additionally, larger trees have deeper roots and can access water from lower soil layers, reducing their water needs.

  3. Soil Type and Condition: Soil composition affects water retention and drainage. Sandy soils drain quickly, necessitating more frequent watering, while clay soils retain moisture better and may require less frequent watering.

  4. Weather Conditions: Extreme heat, wind, and low humidity accelerate water evaporation from the soil, increasing tree water needs. On the other hand, cooler temperatures and higher humidity can reduce the frequency of watering.

  5. Mulching: Applying a layer of organic mulch around the base of trees helps retain soil moisture, reducing the need for frequent watering.

  6. Tree Health: Stressed or diseased trees may have compromised root systems, affecting their ability to absorb water effectively. Such trees may require more attention and regular watering.

Determining the Watering Frequency

Now that we understand the factors influencing tree watering needs, let's delve into the six key tips to help you determine the right watering frequency for your trees in 100+ heat:

  1. Know Your Tree Species: Research and understand the specific water requirements of the tree species in your garden. Native trees are usually better adapted to local climate conditions and may require less watering.

  2. Check Soil Moisture: Regularly monitor the moisture level of the soil around your trees. Insert a finger or a soil moisture meter into the soil to determine if it's dry or moist. Water when the top few inches of soil are dry.  Use tree bags when you can.

  3. Water Deeply: When watering, aim to saturate the root zone thoroughly. Slow, deep watering encourages roots to grow deeper, making them more resilient to drought conditions. Apply water directly to the base of the tree, avoiding foliage.

  4. Use Proper Irrigation Techniques: Drip irrigation systems or soaker hoses are ideal for efficient and targeted watering. These methods minimize water loss through evaporation and ensure water reaches the tree's root zone effectively.

  5. Water Early or Late: Time your watering sessions for early morning or evening when temperatures are lower, and evaporation rates are reduced. Avoid watering during the hottest part of the day, as this may result in water loss without providing adequate hydration. And use a deep water feeder if you have huge trees that need lots of water.

What Can Liquid Soil Aerator Do for Trees During Hot Summer Heat?

During the scorching summer heat, trees face numerous challenges to their survival and health. One of the key issues they encounter is compacted soil, which hinders root growth and reduces nutrient and water absorption. To combat this problem, many gardeners and arborists turn to liquid soil aerators. In this article, we will explore what liquid soil aerators are, how they benefit trees during hot summer heat, and why they are a valuable tool in tree care.

Understanding Liquid Soil Aerators

are soil treatment products designed to improve soil structure and increase aeration. They contain a combination of natural ingredients, such as humic acid, seaweed extracts, and other organic compounds. These ingredients work together to break up compacted soil, enhance microbial activity, and promote root development.

Benefits of Liquid Soil Aerators for Trees in Hot Summer Heat

  1. Improved Water Absorption: Compacted soil impedes water penetration, making it difficult for tree roots to access moisture. Liquid soil aerators help loosen the soil, allowing water to infiltrate more easily. This can be especially beneficial during hot summer months when water evaporates quickly.

  2. Enhanced Nutrient Availability: Compact soil limits nutrient availability to tree roots. By improving soil structure, liquid soil aerators create a more favorable environment for nutrient uptake. Trees can better absorb essential nutrients, promoting overall health and resilience.

  3. Increased Root Growth: Compact soil restricts root growth and can lead to shallow root systems. Liquid soil aerators help break up the soil, allowing roots to penetrate deeper into the ground. Deeper roots provide better stability and access to water and nutrients, making trees more resilient during periods of heat stress.

  4. Promotion of Soil Microbes: Liquid soil aerators contain organic compounds that stimulate microbial activity in the soil. Beneficial soil microbes contribute to nutrient cycling, decomposition of organic matter, and overall soil health. By promoting microbial growth, liquid soil aerators create a symbiotic relationship that benefits both trees and the soil ecosystem.

  5. Improved Drainage: In areas with poor drainage, excess water can accumulate around tree roots, leading to root rot and other moisture-related issues. Liquid soil aerators can help improve soil porosity, allowing excess water to drain properly. This prevents waterlogging and ensures that trees receive adequate oxygen, which is crucial for their survival.

  6. Long-Term Soil Health: Using liquid soil aerators regularly can have cumulative benefits for soil health. Over time, the loosened soil structure and increased microbial activity lead to improved soil fertility, better water retention, and enhanced overall growing conditions for trees.

How to Use Liquid Soil Aerators

To use liquid soil aerators effectively, follow these general guidelines:


  1. Read and Follow Instructions: Read the product label carefully and follow the manufacturer's instructions regarding application rates and frequency.

  2. Apply at the Right Time: Apply liquid soil aerators during cooler parts of the day, such as early morning or late evening, to minimize evaporation. Avoid applying during periods of drought or extreme heat when the effectiveness may be reduced.

  3. Water-In After Application: After applying the liquid soil aerator, water the soil thoroughly to help distribute the product and ensure it reaches the root zone.

  4. Repeat Applications: For best results, repeat the application according to the product instructions. Regular applications will gradually improve soil structure and provide ongoing benefits to tree health.


Liquid soil aerators are valuable tools for tree care, particularly during hot summer heat when compacted soil can be a significant challenge. By using liquid soil aerators, you can improve water absorption, enhance nutrient availability, promote root growth, stimulate soil microbial activity, and improve overall soil health. These benefits contribute to the health, resilience, and long-term survival of trees. When using liquid soil aerators, always follow the product instructions and consult with local arborists or gardening experts for specific recommendations in your region.
