Mulch does more than just make your landscape look neat and polished—it plays a big role in keeping your plants healthy and your garden low-maintenance. Whether you’re refreshing beds or starting from scratch, here’s what you need to know.
Why Mulch Matters
Mulch is one of the easiest ways to improve your landscape while protecting your plants at the same time. It helps:
- Retain moisture so soil doesn’t dry out as quickly
- Regulate temperature by keeping soil cooler in summer and insulated in winter
- Reduce weeds by blocking sunlight and making them easier to pull
- Prevent erosion from wind and rain
- Improve soil health as it breaks down over time
It’s also key for helping new trees, shrubs and plants get established successfully.
A Simple Way to Upgrade Your Landscape
Fresh mulch instantly makes any yard look cleaner and more professional. Those crisp, well-defined beds you notice in great-looking landscapes? Mulch is usually the secret.
Plus, it makes maintenance easier—especially when it comes to weeds. In loose, mulched soil, weeds are much easier to remove compared to compacted ground.
How Much Mulch Do You Need?
Figuring out how much mulch to buy is easier than it sounds.
First, calculate your square footage:
- Rectangle or square: length × width
- Triangle: (base × height) ÷ 2
- Circle: 3.14 × radius²
Then, use these formulas:
- For bagged mulch (cubic feet):
Square footage × depth (in inches) ÷ 12 - For bulk mulch (cubic yards):
Square footage × depth (in inches) ÷ 324
Tip: One cubic yard covers about 324 square feet at 1 inch deep.
Taking a few minutes to calculate helps you avoid buying too much or not enough.
Mulching Tips for Best Results
- Apply 2–3 inches of mulch in new beds
- Refresh existing beds with 1–2 inches each spring
- Use about 2 inches to protect perennials in winter
- Don’t pile mulch against plant stems or tree trunks, it can lead to pests and disease
A Small Step with Big Impact
Mulching is one of the simplest ways to boost your landscape’s health and appearance. With the right amount and proper application, you’ll enjoy fewer weeds, healthier plants and a yard that looks great all season long.
