Mulching is among the commonest gardening practices, but so many landscapers and gardeners do all of it mistaken.
You may not suppose there might be a “mistaken approach” to mulch, however there positively is. Mulch not solely beautifies your backyard and suppresses weeds, it additionally interacts with the soil and serves as a house for helpful bugs and organisms. When finished appropriately, it helps to construct and shield soil and assist vegetation.
What mulch does on your backyard (moreover make it look fairly).
Once you apply a wood-based mulch resembling pine bark, cedar chips, or wooden chips to your backyard beds (no panorama cloth beneath!), the mulch interacts with the soil. It promotes gasoline trade on the floor and slows and aids water penetration, which reduces erosion. Mulch additionally slows evaporation and reduces soil compaction, as foot visitors doesn’t come into direct contact with the soil. Over numerous seasons, the wooden mulch slowly breaks down with the assistance of fungi on the soil floor, offering a kind of composting.
However not like composting, the breakdown of mulch is much like how new soil is made in a forest. In woodlands, wooden and leaves that fall from timber and vegetation sit on the soil floor and really slowly deteriorate. Whereas doing so, this so-called duff layer helps the varied ecosystem close to the soil’s floor and ultimately turns into the humic acids that feed vegetation. And it’s the identical in your backyard – consider mulch as future soil.
Mulch is not only for adornment
Sadly, many householders view mulch as strictly ornamental and that’s why inorganic merchandise like dyed, shredded rubber “mulch” proliferate. These merchandise do little to assist your backyard or its vegetation, and a few may even develop into an environmental hazard. Inorganic mulches like rubber by no means utterly break down and ultimately have to be faraway from gardens and shipped to a landfill. That’s clearly not nice for the ecosystem (this doesn’t embrace inorganic mulches like stone – see under).
Mulch volcanoes could kill your timber.

Mulch volcanoes are completely the mistaken method to mulch round timber. The mulch traps moisture towards the bark and impacts the tree’s long-term well being.
Simply say no to mulch volcanoes! Inexperienced landscapers are infamous for this tree-killing apply. Not solely does piling mulch across the base of a tree promote bark decay, nevertheless it additionally makes a positive residence for mice, voles, and different small rodents. If that wasn’t purpose sufficient to cease making mulch volcanoes, the tree’s roots will develop into the mulch, which suggests you’ll have roots rising above the soil line. That is very, very dangerous for the tree’s long-term well being and will kill it.
Mulch ought to all the time be a number of inches away from the tree trunk and by no means up towards it, a lot much less protecting the bottom of the tree. Mulch isn’t wanted after the primary season when the tree has taken root, and after that time it’s strictly ornamental. And don’t fear about grass rising below a tree – it won’t intrude with the tree’s uptake of moisture and vitamins. Tree roots develop deep within the soil, far under the grasses roots.
