Should Old Mulch Be Removed?

The upcoming spring season excites gardeners and begs the question, should old mulch be removed? Mulch applied last fall has undoubtedly protected your soil from cooler temperatures, but will your old mulch protect your new young seedlings from harm? Depending on the type of mulch, you may not have to worry about replacing last year’s ground cover. 

Gardeners have countless mulch options, from discarded wood chips to crushed stones. Thankfully, many mulches may require only minor adjustments in lieu of complete replacement this spring. This blog post outlines the importance of mulching and answers the question, should old mulch be removed?

Understanding Mulching

Mulching has been an essential agricultural practice since ancient times. The first written evidence of mulching occurred in China during 500 BC, underscoring the value and effectiveness of refreshing garden mulch. Thanks to the widespread availability of various types of mulch and organic matter, farmers and gardeners have plenty of ways to protect their trees and shrubs from fluctuating temperatures, diseases, and insect infestations. 

Some of the most popular types of mulch include the following: 

  • Wood chips
  • Sawdust 
  • Gravel
  • Straw
  • Pine needles 
  • Cottonseed
  • Buckwheat 

A fresh layer of mulch helps retain soil moisture, protect fragile growing plants from weeds, and add essential minerals to your soil. Gardeners can add mulch twice a year, once in mid-spring and again in late fall, to protect plots from harsh UV rays and freezing temperatures. But, as temperatures rise and Larkspurs bloom, you may ask yourself, should old mulch be removed? 

Removing Old Mulch 

Generally, you do not have to remove last year’s mulch from your landscape. In fact, your soil may benefit from your mulch’s decomposition. However, old or neglected mulch can harm your trees, shrubs, flower beds, and gardens. 

Armed with helpful information, you can answer the question, should old mulch be removed? Look out for the following signs of concerning mulch: 

Fungal Infections 

Fungal infections common in trees, such as Apple Scab Disease and Fire Blight, can also affect wood-based mulches. Certain fungal infections feed on decomposing wood mulches and easily spread to nearby flowers, plants, and shrubs. Fungal infections first appear yellow, orange, and red and become powdery white as summer progresses. 

Insect Infestations 

If you notice abundant insects crawling through your garden, you may have to remove old layers of mulch. Wood-boring insects feed on organic matter and use rotted wood to build nests, reproduce, and seek moisture. Research your area’s rules and regulations regarding safely removing infected mulches. 

Improper Mulch Application 

Mulch applied too closely to shallow roots and young seedlings can stifle plant growth. When asking yourself, “Should old mulch be removed?” inspect your garden for tightly packed mulch. Densely packed mulch prevents photosynthesis by blocking water and sunlight from reaching nutrient-deficient root systems.
