How to Mulch

How to Mulch
You’ll want to start mulching at the right time of year and follow some simple steps for the best results. First, measure and calculate the area you need to cover and the amount required. Next, evenly spread 2-3 inches over beds and gardens. Then, thoroughly water the mulch to help it adhere and settle in place.

Finally, consider color-enhancing treatments to make the mulch appearance last longer if desired. Following these basic mulching guidelines will help you reap all the benefits mulch has to offer in protecting and enriching your landscape.

Step 1: Measure

Measuring accurate depth keeps moisture locked in like a snug blanket. Grab a ruler and take several depth checks to find the sweet spot – 2 to 3 inches deep. Rake it smooth and even. The right tools make proper mulching a breeze to retain moisture.

Step 2: Spread the Mulch

Spreadin’ the mulch 2-3 inches deep around plants after the last frost insulates their roots and reduces summer weeds before they emerge.

  • Rake to maintain depth
  • Replenish annually
  • Prevent erosion
  • Promote drainage
  • Avoid suffocation

Spreadin’ mulch protects plant roots, reduces weeds, and retains moisture through the growin’ season.

Step 3: Water

After spreading the mulch, give it a good soak with the hose so it settles in nicely around the plants.

Water thoroughly Until saturated Helps it set
Moisten roots And surrounding soil Prevent drying out
Activates microbes To feed plants And break down mulch

Keep the bed moist while plants establish in the mulch. Proper watering now prevents problems later.

Step 4: Make the Color Last

To really extend your garden’s color into fall, lay down mulch in mid- to late spring like a warm blanket, tucking your plants in before the winter’s chill arrives. Before the colors fade, give the mulch a good raking and shampoo to freshen it up.

How Much Mulch to Use

How Much Mulch to Use
After discussing when to apply mulch, it’s equally important to know how much mulch to use for the healthiest plants. Applied too thin, mulch gets spotty and allows weeds to poke through. Too deep, and mulch can prevent water and air from reaching plant roots.

More tips:

  • For trees, mulch 3-4 feet out from trunks. Avoid mulch touching bark.
  • Annual beds need just 1-2 inches of mulch to allow new sprouts to emerge.
  • If weeds peek through, add another thin layer. Rake mulch smooth before topping off.
  • Try compost or shredded leaves as natural, free mulch alternatives.
  • Lay cardboard or landscape fabric before mulching to block weeds for good.

Proper mulch depth makes the difference between just getting by and getting the most from your garden.

Dos and Don’ts When Using Landscape Mulch

Dos and Don
You can keep your plants healthy and your yard looking great by laying down a couple of inches of mulch around them in early fall, before the ground freezes up. The mulch will act like a cozy blanket, protecting those roots from the cold winter winds and locking moisture into the soil so your plants thrive next spring.

When spreading mulch, make sure you’ve got the proper tools – a rake and shovel will make quick work of it. Focus on areas around trees, shrubs, and garden beds. And remember: less is more. Just a 2-3 inch layer suffices; any deeper could encourage pests like slugs. Keep it pulled back a few inches from plant stems and trunks, so they can breathe.

And never pile mulch against the house. That creates a highway for insects right into your home.

When done right, mulching cuts down on watering and weeding. So take the time to prep your beds, lay your mulch, and you’ll reap the rewards with healthier plants next season.
