Use and Application of Mulch


- helps suppress weeds and makes them easier to remove

- protects soil from compaction and erosion due to rain

- protects sensitive plants against cold damage

* Add mulch to beds if needed. More than 2" total depth of mulch is not recommended

* Compost is a mulch containing significant amounts of decomposed organic matter

* Compost, leaves, and moss, are effective soil builders

* Leaves provide good cover for bare-dirt beds and slopes

* Leaves left in beds can be raked up if they become unacceptably unsightly after at least some of the mass breaks down; or, till them back into the bed in the spring, or add more mulch later over the leaves.

* Keep mulch away from trunks of shrubs and trees.


* For garden area's and closely planted beds, Compost is a good mulch to improve soil quality and provide organic nutrients.

* Cedar Grove compost is a good product.
It can be initially odorous and mucky during winter and early spring.

* Compost of variable quality is usually available at landscape materials outlets. Check for excessive sand and sawdust in mix.

* For open bed area's, play area's, trails;

* Arbor chips work well - they can be applied more thickly than other mulches, but may be more time consuming to apply, and variable in quality

* play chips can also be used as mulch but it will have a different appearance and color you may not prefer

* "Beauty Carpet" was attractive and conformed to play area specs. I am not sure if it was a compost, or if it is still available. Similar products may now be available.

* Coarse bark mulch will last quite a bit longer than finer bark

* Cedar chip mulch is sometimes available, - you may try Issaquah lumber in Seattle. Shredded cedar mulch is generally available, and i think it is a good product.

* wood chip mulch, especially dyed products, should be certified not to contain shredded pallets before using it.

Respectfully, don
