Organic Mulching Techniques for Denver Landscapes
Mulching is a landscaping technique that uses organic or inorganic materials to cover the areas around a tree or plant’s base. There are a number of different reasons to do this, and the materials you choose can greatly benefit the soil. Here, in the Denver area, we experience a very dry, arid climate, and many plants suffer from a lack of moisture. Mulching can help protect your plants from drought-like conditions so they continue to thrive throughout the year.
Why is Mulching Important in Denver?
Mulching is an important component of any landscape, but especially in places where the soil needs a boost. In Denver, the air is dry and cool, leaving little moisture in the soil for plants to soak up. Mulch helps to retain moisture so that plant roots get a chance to access it, even when the weather is dry. Mulch also keeps the soil from getting too hot in the winter and too cold through the summer months. It acts as a layer of insulation for a plant’s delicate roots, so the plant can thrive—even during extreme temperatures.
The Correct Mulching Technique
Mulch comes in a variety of organic and inorganic materials. Although gravel and landscaping fabric have their place, it’s always best to choose organic materials for your landscape. Most homeowners opt for shredded or chipped tree materials, which can be spread across the surface of your soil. Other options include grass clippings, leaves, pine needles, and straw.
When mulching your landscape, it’s important to follow the right technique. Improper mulching can damage your plants and trees, leading to disease, infestation, and even tree death. Start by spreading mulch around the base of your plants, and make sure the layer is two to four inches deep. If you’re mulching around trees, spread the material around the base of the trunk and out to the drip line, if possible. Avoid creating a “volcano,” where mulch is piled up around the tree’s trunk. Instead, leave some space where the trunk meets the earth, so the root flare is exposed.
What Plants Should Be Mulched?
Ideally, homeowners should always mulch around the bases of trees and shrubs. Many other perennial plants, like hostas, and especially clematis, can also benefit from a layer of mulch. Clematis is notorious for loving the sun, but its roots prefer a cool place to grow. Mulching provides a thermal and water-retaining place for roots to grow, and it prevents many weeds from taking over your landscaping space.
Some plants that trail or spread may not benefit from mulching. Added mulch may make it more difficult for the plant to grow.
How Much Mulch Should You Use?
In most cases, it’s best to spread mulch in a layer that is two to four inches thick around the base of your plants. The width should reach out to the drip line of your plant or tree, if possible. This protects the roots from extreme temperatures and retains moisture for the roots.
How Often Should You Re-Mulch?
Mulch breaks down over time, leaving nutrients to soak into your soil. Expect to re-mulch every year or every other year to keep an even layer around your landscape. Check the mulch each year to determine whether you need to add more.
