Question
Hi!
I have a large yard and need to start using a permanent, hard, non-biodegradable mulch for lower maintenance. I do not have the time to replenish traditional wood mulch every year. I can get pea stone locally at a good price but on the south and west, full sun, it will reflect the sun and have solar gain (releasing heat towards house in evening). Shade is limited due to concrete drive and approachment.

So, is there such a thing as hard mulch that would NOT reflect the sun and it's heat towards house on the south & west? I plan to use the pea stone on the east and north side of home as well as the outer flower/shrub beds.

Thank you for your time and if you have any suggestions!

Pat,

You will definately have heat load problems using the stone on the south and west.  

I believe the benefits of organic mulch materials always outweigh any drawbacks when compared to stone.  Organic mulch keeps the soil cooler, maintains soil moisture much better than stone, and does not look as sterile.  

Contrary to popular belief you do not have to re-mulch every year, if you use the correct materials.  Most wood mulches are just that wood.  Wood decomposes very quickly.  Bark mulches are much more desirable.  But there are big differences in hard and softwood bark.  Always choose pine, cedar, or cypress.  These last for several years.  I use cypress.  Typically each year I add 10 bags to areas in the spring.  It took 200 2 sq.ft. bags to do my yard.  Cypress also has some insectical properties that may help repel termites and ants.

If you are absolutely against bark mulch then there is a product that has been on the market for a couple of years.  It is shredded tires that looks like bark mulch, is dyed to look like bark mulch, and is almost indestructable.  Look for a dealer in your area.

Good luck in the garden.
