What may become a problem when mulching?

Disease. Most fungal and bacterial diseases require moisture to spread and reproduce. Trunk diseases gain a foothold into the moist, decaying bark tissue under the mulch. Once established, the disease organisms ultimately invade the inner bark, starving the plant, and finally kill the plant.

Can you put new mulch over old mulch?

Mulch gradually breaks down, adding beneficial nutrients and other organic matter to the soil. ... However, if you're down to an inch, top off the old layer with an additional inch of new mulch to keep it at its optimum level. Sometimes, mulch can knit together and start to mat–shredded hardwood in particular.

Can you put too much mulch around plants?

Yes, too much mulch can kill plants, especially if piled up too close to the base of the plants. Mulch that is too thick can suffocate roots, overheat soil in hot sunny weather, and encourage diseases due to excess moisture.

How do you get mulch to stay in place?

The only way to keep mulch completely in the flower bed or garden is to edge it with something high enough to hold in the mulch in place during a storm. Some ideas include: Landscape Edging: Wood, metal, plastic, or stone edging can help keep mulch in its place.

What's the difference between mulch and wood chips?

Depending upon the source, the wood chips may contain bits of bark and leaves. Wood-chip mulch tends to contain larger chunks than shredded mulch; the pieces range, on average, from 1 to 5 inches long and up to 3 inches across. ... Wood chips also absorb moisture and tend to break down more slowly than shredded mulches.

What was the problem with the mulch this year?

But the biggest problem we see today is too much mulch. When added year after year, mulch can actually harm plants by creating a layer that doesn't decompose and doesn't allow root growth. The soil becomes so matted that nutrients and water can't penetrate to the roots, and the plants will suffer.

Should I remove old mulch before adding new mulch?

For an annual bed, remove old mulch before you till the soil and add compost. If you're applying mulch to a perennial bed, you might be tempted to just add a new layer of mulch on top, but this can cause rot, nutrient starvation, and plant death. Remove as much of the old layers as possible before you add more.

Should you mulch in the spring or fall?

But you can apply fall mulch just like you do in spring, adding enough to refresh what's broken down. Many landscaping professionals actually practice—and prefer—fall mulching. Fall mulch works like spring mulch to retain soil moisture, suppress weed growth and protect bare soil from erosion.

What do you do with old mulch in flower beds?

But what if the old mulch has, in fact, decomposed appreciably over the course of the winter? In that case, work it into the ground as organic matter so that it can serve as a soil amendment, along with the compost. Then acquire a load of new mulch as a replacement.

Will black mulch kill my plants?

This dyed wood mulch does not break down to enrich the soil as good mulch should. Instead it leaches the dye along with the possible contaminants (chromium, copper, arsenic and others) into the soil harming or even killing beneficial soil bacteria, insects, earthworms and sometimes the plants themselves.

What happens if you use too much mulch?

The same moisture that is held in with the proper amount of mulch grows exponentially when too much mulch is installed. This will make the soil waterlogged and encourage harmful diseases in plants. Those weeds that are suppressed? If there's not enough mulch installed then those weeds will just sneak right on through.

Will putting mulch around a tree kill it?

That's right, mulching, or incorrect mulching, can kill your trees. ... This is not a good way to mulch around trees as it causes too much moisture to build up around the root ball. This can lead to fungus, rot and decay and ultimately lead to the trees death.
