Why You Should Mulch Underneath Trees

If you’ve noticed that most people tend to mulch underneath their trees, you might be wondering if this is a purely aesthetic preference, or is there some other reason? And maybe you’re tempted to skip mulching under your trees, because it seems like an extra, unnecessary step. But actually, this practice is not just done for appearances, and there are several good reasons that you should go ahead and add mulch at the bottom of your trees. In fact, there are six very good reasons!

Mulch will stop erosion and help retain moisture. Adding a layer of mulch around the base of your trees will stop the soil from eroding away in those spots. It will also help to retain vital moisture in the soil. This is extra important in our climate, since Southern California experiences frequent droughts.

Mulch will keep nutrients in your soil. When you reduce water runoff and erosion, you also prevent nutrients from washing away. Adding mulch to the base of your trees will help to trap more nitrogen, potassium, and phosphorus to feed your tree.

Mulch insulates the tree’s roots in winter, and keeps them cool in summer. A more stable temperature prevents damage to the tree’s roots, and of course we worry about high heat here in our climate. Mulching under your tree can reduce heat from the sun and lower the temperature of the soil.

Mulch fights weeds. Without weeds at the base of your tree, you won’t have to weedeat there or apply harsh chemicals. And because you won’t be weedeating in that spot, you can protect the trunk of your tree from potential damage by the equipment.

Mulch increases your tree’s growth rate. Since your tree is protected from various risk factors, well nourished, and thoroughly watered, it can grow much more healthfully. It might surprise you that simply adding mulch can potentially double your tree’s growth rate! That’s important if you’ve planted a young tree and want to get it established quickly.
