Basic kits exist, but professional soil engineers provide in-depth analysis and construction recommendations.

A light layer of mulch can help protect a tree, retain moisture, and keep the soil healthy. However, it’s important to avoid over-mulching or piling the mulch up around the trunk of a tree, a practice notoriously called “volcano mulching.” That piled mulch can increase the chances of rot and disease on the tree trunk as well as overwhelming the soil, which needs access to a certain amount of air. Topped trees have it hard enough: mulch sparingly while they heal.

Costs depend on waste volume, service frequency, and additional options like bulk pickups.

Colored mulch can be bad for plants in that it robs them of nitrogen as it depletes the soil to break itself down. With this in mind, it’s a good idea to test your soil to check the nitrogen levels. If the nitrogen levels are low, use fertilizer with extra nitrogen or switch to regular mulch.

Another downside of colored mulch is if it’s heavily contaminated, it can contaminate the soil and damage your plants. To avoid this, look for the MSC certification logo on the mulch bag before purchasing.
