Five Mulching Mistakes (Plus The Right Way To Do It) (2024)

Posted On by Douglass Delano

There’s nothing better than big fresh mounds of mulch, right? Mulch makes everything better.

But watch the mounds. And don’t spread it too thick. Or too thin.

Is there more to mulch than you think?

Maybe.

Let’s take a look at the top mulching mistakes to avoid.

Bonus: we’ll tell you how to do it right.

Mistake Number 1: Too Much Mulch

If mulch is so great, even more is better, right?

Nope.

Our Level Green Landscaping crews spread one to two inches of mulch in the spring to help beds retain moisture, deter pesky weeds and keep the landscape looking polished.

Five Mulching Mistakes (Plus The Right Way To Do It) (1)

But piling it on too thick is one of the mulching mistakes a lot of people make.

Use more than a couple inches and your soil will become soggy, encouraging plant diseases. Too much mulch will suffocate your plants’ roots. Just like you, they need air to breathe.

Stick to a nice even layer of one to two inches thick.

Mistake Number 2: Not Enough Mulch

If you don't add enough mulch, it won't keep weeds from pushing their way through. It won’t keep your soil nice and moist and help you conserve water.

Basically, it won’t be doing its job.

Mulch is organic, so as time passes, you’ll notice it will settle and look thin. That means it’s breaking down, enriching your soil and making it more fertile.

It’s still hard at work, boosting your landscape, but when it’s thin, it doesn’t look so great anymore.

So don't try to stretch your hard-working mulch an extra season. Plan to replace it every spring. Some of our customers add an extra layer in fall, too, to ensure that great fresh mulch look year round.

Mistake Number 3: Mulch Volcanoes

Yes, this sounds sort of cool, but it’s among the big mulching mistakes.

We understand how this happens. People think if mulch is so great, they really want to pile it on, mounding it right up against the tree.

The base of your tree needs to breathe. Its roots need to access oxygen. Stifle it with a big mound of mulch and it can get mildew and root rot.

These mulch volcanoes trap moisture against the tree bark, encouraging disease. Damaging insects will burrow in and hang out there.

Keep mulch two or three inches away from the trunks of your trees to keep them happy and healthy.

Mistake Number 4: The Wrong Mulch

Maybe your neighbor is bragging about the free mulch he got from his municipality when they shredded old Christmas trees, or the bargain load he picked up at the hardware store.

All mulches are not created equal. The free stuff can contain pesticides, weed seeds or insects.

Our favorite mulch here at Level Green is double shredded hardwood bark mulch. We go the extra step to use dyed dark brown mulch. The added color helps it stay nice and dark longer, without fading as quickly.

It costs a bit more, but our customers appreciate the rich, dark look throughout the year. It contrasts nicely with your green and colorful plants, adding to your property’s appeal.

This is our top pick, but if you prefer black or red hardwood mulch, we can happily set you up.

If your property includes a playground, we recommend mulch designed specifically for play surfaces — either clean wood with smooth edges or recycled tire mulch.

Mistake Number 5: Not Using Mulch

If you’ve hung out here with us at all, you know the great benefits of mulch. Still, if you’re trying to save a few bucks, it’s tempting to skip it.

Please don’t. We can’t say enough about the benefits of the stuff.

First, a fresh carpet of rich brown mulch looks fantastic, unifying your landscaping and giving the whole place a fresh, clean appearance.

But it does wonders for the health of your soil and plants, too.

A nice layer of mulch helps your soil retain moisture, so you won't have to water as much. Moist roots are happy roots.

It keeps those pesky weeds at bay by blocking the sunlight they need to sprout.

Mulch protects your plants' roots — both from the scorching sun and winter’s chill.

Leaving bare soil on your property will cause erosion and sediment runoff.Mulch prevents rain from washing away your precious landscape soil.

It’s Not Too Soon To Ponder Mulch

We spread mulch twice a year, in the spring and the fall.

We start preparing planting beds at the end of February, clearing out winter’s debris, neatening edges, cutting back ornamental grasses and perennials.

Then we spread one to two inches of mulch to make everything neat and tidy.

Mulch time will be here before you know it.

However, this isn't necessary because mulch will decompose over time and you can just add a new layer on top of the old one! However, you don't want your mulch layer to exceed 3 inches in thickness. So, you can remove some of the old layer if necessary to keep the mulch at the right amount.

What month is the best time to mulch? ›

In general, mid- to late-spring is mulching season; this is when the soil is warming up from the freezing temperatures it experienced all winter. Mulching too early will slow down the warming process, which the soil needs to do its job.

Mulch can kill whole trees if it's packed in excess quantities against a tree's trunk – a practice known as “volcano mulching”. Water after applying mulch. Smooth the mulch, then soak the beds to settle it in.

Is it better to mulch or not to mulch? ›

Mulch can be a positive addition to any garden. It helps preserve moisture, protects tree roots, and can help keep emerging weeds at bay by depriving them of sunlight. 1 Some mulches are also pre-treated with herbicides or insecticides to deter weeds or insects (check labels to be sure).

What color mulch for a yellow house? ›

Red mulch is especially well-suited to a palette of gold and warm tones. Black mulch around green foliage, such as hosta and sweet potato vine, makes the colors stand out. For gray and contemporary homes, use black mulch.

Does mulch attract termites? ›

The presence of mulch in your yard might not mean you're going to get termites, but it does mean that you're increasing your risk. The best way to decrease the risk of termites in mulch is to maintain a long-term termite prevention and control with a pest management professional.

Should you remove old mulch each year? ›

So, should you remove old mulch? Expert green thumbs contend that getting rid of last year's mulch is completely unnecessary. Mulch gradually breaks down, adding beneficial nutrients and other organic matter to the soil. Removing pre-existing mulch every year only ends up to be extra work and a needless expense.

What should I put down before mulching? ›

If you're mulching around a tree, you can remove the grass or simply put down a layer of black-and-white newspaper, thoroughly water it down and then cover it with your mulch. Add mulch to a depth of 2 to 4 inches. Leave a few inches around the trunk free of mulch.

Why are my plants dying after mulching? ›

Mulches used improperly can have a detrimental effect if: – They make contact with the stem, trunk or crown of the plant causing disease and rot. – They're applied too heavily and keep oxygen from reaching the roots. (1.5 – 2.5″ is usually plenty for perennials, 3″ for trees.)

What is the problem with mulching? ›

Over-mulching can create an anaerobic (low or no oxygen) environment that allows fungal diseases to develop in plant stems and roots (some are toxic to humans). Mulching at the too early in the spring can create water logged soils that may kill drought tolerant plants.

When should you mulch and when not? ›

Spring is the best time to apply mulch because the soil is warming up from winter and will need additional nutrients to jump-start from the plant's hibernation. Mulch does not need to be applied in fall because natural organic material like leaves and twigs will cover areas of the ground.
