The Importance of Mulching: How to Protect Your Trees This Spring | Why Mulching Matters When It Comes to Protecting Your Trees
Spring is upon us – and when it comes to nature, this season is the best time for renewal, regrowth, and re-examining the ways to support your trees. In this article, we’ll take a look at the importance of mulching, as well as some options when it comes to choosing the right mulch.
Spring offers endless opportunities for gardeners. The months following winter can be decisive when it comes to giving the fauna in your garden the resources it needs in order to thrive.
And, when it comes to your trees, one of the most important ways of supporting them during spring is through proper mulching.
What is Mulching?
Put simply: Mulching is the practice of covering the soil around plants/trees with a layer of material (organic or inorganic) such as mulch, compost, bark, or even rocks.
The reason this is done is because ‘mulching’ acts as a kind of protective blanket over the roots, shielding them from temperature changes, helping them retain their moisture, and improving the overall health of the soil.
When done right, mulch can significantly enhance the growth and longevity of your trees – and the springtime period is crucial!
Let’s take a closer look:
Why Mulching Matters for Your Trees?
There’s a tendency among some novice gardeners to think that trees – sturdy as they are – will always look after themselves. However, individuals can offer various ways to help their trees get optimal growth – as well as help their gardens look super neat.
Here’s why mulching matters for tree health:
Mulching Retains Soil Moisture
No matter where you live in the world, your climate will fluctuate from season to season. This can pose risks to the trees in your garden.
As we head into spring and summer, one of the big challenges faced by trees is maintaining consistent soil moisture (the word ‘consistent’ is key here, as consistency is something all trees need). Essentially, mulch acts as a barrier, reducing water evaporation from the soil. This means your trees stay hydrated for longer, reducing your need to tinker with a watering schedule – and giving your trees that much-needed consistency.
Mulching Regulates Soil Temperature
Again, climate and temperature changes can lead to stress on tree roots. But mulching helps mitigate these problems. A layer of mulch insulates the soil, keeping it cooler in the summer and warmer in the winter.
Mulching Suppresses Weeds
Weeds are wily competitors when it comes to all the essential things that a tree needs – such as nutrients and water. The benefit of mulch is that it blocks sunlight from reaching weeds (or their seeds), preventing germination. On top of this meaning that your trees have more nutrients, it also means that you’ll spend less time weeding.
Improves Soil Quality
This one is a very straightforward benefit: organic mulches, like wood chips or even compost, gradually break down and enrich the soil with nutrients. In the long run, they’ll keep your soil quality high.
How Do I Choose the Right Mulch for My Trees?
So far, we’ve mentioned different mulches that you might use around your soil. But you’re probably wondering which one is the best – or which is the right one for your particular tree.
It’s fair to say that not all mulches are created equal. The best type depends on your trees and soil conditions (and it’s worth contacting a tree health expert if you’re ever uncertain). Here are some common options when it comes to mulch:
Organic Mulches
Wood Chips/Bark: We’ve already mentioned wood chips; they’re excellent for moisture retention and weed suppression. They also break down slowly, adding organic matter to the soil and improving its quality.
Compost: Similarly, compost is nutrient-rich and great for improving soil fertility. But it’s worth adding that compost is best used in combination with other mulches.
Leaf Mould: Decomposed leaves can help improve soil structure and retain moisture. This mulch is particularly Ideal for woodland gardens.
Inorganic Mulches
Gravel/Stones: While stony mulch won’t improve soil health, it is useful in very dry climates. It is a low-maintenance option and is also good for stopping weeds from sprouting.
Rubber Mulch: Again, this is a low-maintenance option. Rubber is long-lasting, but it doesn’t add nutrients so will not help with soil health.
If, after reading this, you’re under the impression that organic mulches are the better choice most of the time – then you’d be right! For most trees, organic mulches are the best choice because they improve soil health and have other nutritious benefits.
Final Thoughts: Common Mistakes to Avoid
Now that you’re a mulching expert, here are a few tips to remember as you go over your options:
Be careful not to use too much mulch: Excessive mulch – of any kind – can lead to root rot and oxygen deprivation.
Don’t place mulch directly against a tree trunk!: This is a VERY common mistake. While you might be tempted to pile your mulch high against the tree trunk, this can actually invite pests and diseases – as well as contribute to tree rot and deprivation (mentioned above).
