There are two basic kinds of mulch: organic and inorganic. Organic mulch includes materials such as chopped leaves, straw, grass clippings, compost, wood chips, shredded bark, sawdust, pine straw, and even paper. Inorganic mulch includes black plastic and geotextiles.
There are times when trees need to be removed. There are many reasons for this like preventing property damage due to branches or roots, problems with pests or disease, or if the tree is endangering other plants or flowers in your green space.
