Why mulch? Because mulching improves water retention, optimizes soil temperature, and reduces general stress on plants and plant roots. Mulch also keeps weeds out and prevents soil compaction. Finally, mulch adds to the quality of the soil as it decomposes. In this article, we\u2019re exploring all things mulch, from proper mulching technique to types of mulch to common mistakes to avoid.<\/p>\n
How to Mulch Your Tree<\/strong><\/p>\n Clear away grass around your tree within a 3 to 10 foot area, depending on the tree size. Add natural mulch to this cleared area, about 2 to 4 inches deep, but ensure mulch does not touch the trunk of the tree. If mulch is piled up around the tree trunk, it will limit the tree\u2019s ability to take in oxygen and nutrients. Consult Portland arborists<\/a> to learn more about proper tree mulching practices and general best practices for Portland tree care.<\/p>\n Mulching Mistakes to Avoid<\/strong><\/p>\n Mulching is a very important aspect of caring for your trees and plants, but acting without enough information may result in unfortunate mistakes. Mitigate these risks by following our recommendations on what not <\/em><\/strong>to do when mulching:<\/p>\n Choosing the Best Mulch for Your Trees<\/strong><\/p>\n Mulch is a blanket term that contains a wide variety of products, each with their own unique form and specialty. The two main categories are organic and inorganic mulch. Organic mulch decomposes and provides additional nutrients to the soil. While organic mulch has to be replenished more often, it is often preferred for its nutritional benefits. Inorganic mulch provides good surface drainage, discourages soil splash onto plants, and daunts moss. Inorganic mulch does not decompose and thus does not need to be replaced as often.<\/p>\n Common organic mulch includes<\/em>: Common inorganic mulch includes<\/em>: Of course, Portland arborists<\/a> will have the best information on Portland tree care.

Don\u2019t over-mulch. <\/em>Too much mulch can cause plants to become stressed in harsh weather conditions. The standard recommended mulching depth is 3 inches.<\/li>\n
\u2022 Farm manure, which is good for shrubs and roses and is useful for nutrients;
\u2022 Composted bark, which is good around trees and shrubs, particularly acid-loving plants, and is quite nutritious;
\u2022 Wood chips that decompose slowly and take nitrogen from the soil;
\u2022 Garden compost that prevents weed seeds from germinating and supplies gradual nutrients;
\u2022 Composted straw, which may contain weed seeds and is low in nutrients, but can also be useful;
\u2022\u00a0Mushroom compost, which supplies some nutrients and decays slowly, but is not recommended for use around acid-loving plants.<\/p>\n
\u2022 Gravel, which is good for drought tolerant plants;
\u2022 Cobbles and pebbles, which are an attractive way to mulch;
\u2022 Coarse grit and stone chips, which can be ideal for small plants such as succulents in raised beds;
\u2022 Black plastic sheeting, which can suppress weeds and is often laid around new trees and shrubs. Geotextile membranes are often useful to retain moisture and suppress weeds around newly planted trees and shrubs.<\/p>\n
