ALAMO – An easy way to promote the health of the trees on your property is to apply mulch. Mulch offers several benefits:
• It insulates the soil, which minimizes sun and wind evaporation following irrigation.
• It keeps weeds down, so your tree has less competition for water and other resources.
• As mulch decomposes, the bacterial activity creates additional nutrients for the tree’s root system.
• It looks nice, which enhances the aesthetic value of your landscape.
However, to get all the benefits of mulch, you need to apply it correctly. Mulch should be applied in a 4- to 6-inch layer around the tree’s outer root area. Don’t put mulch up against the tree’s base, as the fungi and bacteria it creates can have a negative effect on the tree’s epidermis. Since mulch decomposes over time, it should be reapplied annually.
