Why Mulching Your Garden Beds is Worth It Every Year

Mulching is one of those things that looks simple but makes a real difference if you do it right. Most people think of it as a cosmetic thing — and it does make your beds look sharp — but it's actually doing a lot of work underneath the surface.

What Mulch Actually Does

A good layer of mulch slows down weed growth by blocking light from reaching the soil. It holds moisture in during dry stretches so your plants aren't stressed between waterings. It regulates soil temperature, which matters more than people think during Ontario's spring and fall swings. And over time, organic mulch breaks down and improves the soil it's sitting on.

How Much Do You Need

Two to three inches is the target. Less than that and weeds push through without much trouble. More than four inches and you start suffocating plant roots and trapping moisture against stems, which causes rot.

A cubic yard covers roughly 100 square feet at the right depth. For most residential beds in the Orangeville area, one to two yards gets the job done.

Which Type to Use

**Black or brown dyed mulch** is the most popular choice for front yards. The colour lasts longer than natural options and gives beds a clean, finished look that holds up through the season.

**Cedar mulch** has a natural look and a pleasant smell. It weathers to silver-grey over time — some people like that, some don't. It also has mild insect-repelling properties.

**Hardwood bark** is chunkier and heavier, which makes it a good choice for slopes or spots that get wind. It breaks down more slowly than finer mulches.

The Mistakes That Undo the Work

Piling mulch against tree trunks is probably the most common one. It traps moisture at the base and causes rot over time. Keep it pulled back a few inches from any trunk or stem.

Not edging the beds before you mulch is another one. Without a clean edge, the mulch migrates onto the lawn within a few weeks and the whole thing looks messy.

Most beds also need a top-up every spring. Mulch compacts and breaks down over winter and a thin layer doesn't do much.

When to Do It

Spring is the most common time — after your cleanup but before the heat arrives. Getting it down in May locks moisture in heading into summer. A fall application also works well for protecting plant roots through winter.
