As summer heats up in Northern and Central Wisconsin, keeping your trees and landscapes healthy requires some extra attention. Here are some essential summer watering tips to keep your trees, including Red Maple, Balsam Fir, and Eastern Hemlock, vibrant and resilient.

Understanding Your Trees’ Water Needs

Each tree species has unique water requirements, and understanding these can help you tailor your watering schedule. In Wisconsin, common trees such as the White Spruce, Red Oak, and Paper Birch each have specific needs.

“Understanding the specific water needs of different tree species is crucial for their health and growth. For example, Balsam Firs require consistent moisture, while Red Oaks are more drought-tolerant. Our Legacy-Trees have a variety of different moisture requirements, and we can help choose the best one for your property.” says Ted Foley, owner and certified arborist at Foley’s Tree Service, LLC.

Here’s a simplified look at the watering needs of some of the most common trees in Wisconsin:

  • Balsam Fir (Abies balsamea): Thrives in cool, moist environments. Ensure consistent moisture.
  • Eastern Hemlock (Tsuga canadensis): Needs regular watering, especially during dry spells.
  • White Spruce (Picea glauca): Requires moderate watering; avoid waterlogging.
  • Red Oak (Quercus rubra): Deep watering is essential; soak the soil thoroughly.
  • Red Maple (Acer rubrum): Keep soil consistently moist but not saturated.
  • Northern White Cedar (Thuja occidentalis): Regular watering helps, particularly in sandy soils.
  • Tamarack (Larix laricina): Prefers wet soils; increase watering in dry periods.

Best Practices for Summer Watering

  1. Water Early or Late: Watering your trees early in the morning or late in the evening minimizes evaporation and allows trees to absorb moisture more effectively. This is especially important during Wisconsin’s hot summer days.
  2. Deep Watering: Ensure that water penetrates deep into the soil, reaching the tree’s root zone. Shallow watering can cause roots to grow near the surface, making trees more vulnerable to drought. Aim for a slow, deep soaking.
  3. Mulching: Apply a layer of mulch around the base of your trees to help retain moisture, suppress weeds, and regulate soil temperature. Foley’s Tree Service offers bulk mulch sales for water retention. Mulch should be spread 2-4 inches deep, and kept away from the trunk to prevent rot.
  4. Check Soil Moisture: Regularly check the soil moisture around your trees. 
  5. Adjust for Weather: During dry spells or heat waves, increase your watering frequency. Conversely, reduce watering after heavy rains to prevent waterlogging, which can damage roots.

Special Considerations for Different Tree Types

  • Young Trees: Newly planted or young trees need more frequent watering as they establish their root systems. Water these trees 2-3 times per week during their first growing season.
  • Mature Trees: Established trees generally need less frequent watering but benefit from deep soaking. Water mature trees every 2-4 weeks, depending on weather conditions and soil type.
  • Drought-Tolerant Trees: Species like Red Oak and White Spruce are relatively drought-tolerant but still require adequate water during prolonged dry periods. Monitor these trees closely and adjust watering as needed.

“Young trees are especially vulnerable to drought stress. Consistent, deep watering is essential during the first year to help them establish strong root systems,” explains Michael Hooper, a certified arborist at Foley’s Tree Service.

Tree Watering Tips

  • Adequately watered trees will have green grass or vegetation in the radius surrounding the trees.
  • Irrigated lawns should not require further watering.
  • Overhead sprinkler systems watering 30 minutes every other day are preferred after 5 or more days of no rain for trees with no irrigation.
  • Avoid placing irrigation hose at the base of the tree as this will cause oversaturation in the root system.

Signs of Under-Watering and Over-Watering

Overwatered trees typically show signs such as yellowing leaves, soft or mushy stems, and root rot. You may also notice that the leaves are wilting or dropping prematurely.

“Overwatering can be just as harmful as underwatering. It’s important to monitor soil moisture and ensure proper drainage to prevent root rot and other issues,” states Ted Foley

  • Under-Watering: Look for wilted, yellowing leaves, and dry, brittle branches. If the soil is dry several inches below the surface, increase your watering frequency.
  • Over-Watering: Symptoms include yellow leaves, root rot, and fungus growth around the base. Ensure the soil drains well and avoid watering if the soil is already moist.

Environmental Benefits of Proper Watering

Proper watering practices not only keep your trees healthy but also contribute to the environment. Healthy trees provide shade, improve air quality, and support local wildlife. By maintaining your trees, you’re enhancing the natural beauty and ecological balance of Northern and Central Wisconsin.

FAQ: Summer Watering Tips for Trees and Landscapes

How often should I water my trees in summer? Water deeply once a week, adjusting for weather conditions and soil moisture levels. Young trees and newly planted trees require more frequent watering—typically 2-3 times per week—until their roots are established. Mature trees generally need deep watering every 2-4 weeks. Additionally, consider the specific needs of your tree species. For instance, Red Oaks and White Spruces are relatively drought-tolerant, while Balsam Firs and Eastern Hemlocks require more consistent moisture.

What is the best time of day to water my garden? Early morning is the best time to water your garden. Watering in the morning reduces evaporation and allows plants to absorb water before the heat of the day sets in. This helps maximize water use efficiency and keeps your plants hydrated throughout the day.

How can I tell if my trees are overwatered? Overwatered trees typically show signs such as yellowing leaves, soft or mushy stems, and root rot. You may also notice that the leaves are wilting or dropping prematurely. Check the soil moisture by feeling it; if it feels consistently soggy or has a musty smell, it’s a sign of overwatering. Ensure your soil has proper drainage and adjust your watering schedule accordingly.

Are there drought-tolerant plants suitable for Wisconsin? Yes, there are several drought-tolerant plants well-suited for Wisconsin’s climate. Species like Red Oak, White Pine, and certain ornamental grasses such as Little Bluestem and Prairie Dropseed can thrive with minimal watering. These plants are adapted to withstand dry conditions and are excellent choices for sustainable landscaping.

Should I mulch around my trees? Yes, mulching is highly beneficial for your trees. Mulch helps retain soil moisture, suppresses weeds, and improves soil health by adding organic matter. Apply a layer of mulch 2-4 inches deep around the base of your trees, but keep it a few inches away from the trunk to prevent rot and pest problems.
