GOLDEN VALLEY, Minn. - Do you need mulch for your yard but you don't know where to start?

Heidi Heiland of Heidi's Lifestyle Gardens joined KARE 11 News @ 4 to share tips on what, when, why and how to mulch!


WHEN TO MULCH - Mulching should not be performed until June when the ground warms up. If you apply mulch in early spring, you are simply trapping the cold temperatures into the ground. It is also advised to weed the area before applying mulch. Do not simply sweep your weeds under the rug of mulch!

HOW TO MULCH - Typically 1-4 inches of mulch is applied depending on what is being mulched and the type of mulch used. Be careful not to bury perennials too deeply and do not create mulch "volcanoes" around your trees (the latter could encourage stem girdling roots which can spell demise for the tree).

Here is a link to a landscape calculator to help you estimate how much you might need.

BENEFITS OF MULCHING - Include suppression of weeds, retention of moisture. An added benefit for one year mulches is that as they break down they improve soil structure.

GREEN MULCH - To be truly ecologically friendly, consider selecting mulch that is a bi-product, newspaper, leaves, straw, etc.


One year Mulches:

- Cocoa Bean

- Mini Pine Bark Nuggets

- Compost/Humus

Two – Three Year Mulches:

-Shredded/Chipped Bark

- Pine Needle

Lifetime Mulches:

- Rock

- Rubber

Mulch to Avoid- Why kill a tree to grow a flower is a great article to explain how you can save a cypress forest.

Heidi says avoid Cypress mulch. Manufacturers are defoliating forests to obtain this natural resource.
