Shrubs and other plantings stand out
so much more
when framed by a fresh, even layer of pine straw, wood mulch, or
stones.
Professional landscapers and homeowners make an important decision twice yearly, usually during the spring and the autumn, about which product to select for arranging around shrubs, trees, and plantings.
I realized there are pros and cons to each of the materials available.
So, I offer to you this rundown on factors to consider.
I’ll begin with this one, my favorite.
I like the way it looks, it’s longevity, and, importantly, it’s
free
!
I have many pine trees and begin collecting it off the lawn during the fall. It rains down from the trees from October to February.
If I don’t escrow some for use now
and
for later (stored in piles behind the tool house or in large leaf bags), our lawn service mows over it in the spring, and it disappears into a finely chopped dust across the grass.
Another positive aspect of the pine straw is that it usually doesn’t wash away during heavy rains.
It keeps the soil from drying out during hot weather and inhibits some weed growth. In winter weather, it insulates the soil and roots of plants from the harsh, drying effect of winds, ice, and snow.
I like that I don’t have to remove last season’s straw before adding more to the surface.
Pine straw is acidic, which benefits gardening favorites such as camellias, azaleas, magnolias, boxwoods, hollies, junipers, and hydrangeas.
Shredded hardwood or pine wood mulch is the favorite of many homeowners.
Some say they switched from
pine straw to wood mulch because they liked the color and texture better.
I recall a funny incident at my mother’s home after I’d added yellow flowers and about 10 bags of the deep brown, almost black hardwood mulch to the beds closest to her front and back doors, where I thought the colorful contrast would make a beautiful impact.
After a week, Mom said it was no longer as pretty because the mulch had lost its deep shade of brown, and she remarked that its odor had been terrible!
I explained that as the mulch’s surface dries out, it becomes a shade of lighter brown.
I promised her that the strong scent would soon subside, and it did.
After that, we used pine straw contributed by her trees for the mulch. (Side note:
It DOES stink, but you get used to it for the first few weeks of the odor, which lessens greatly.
Wood mulch is so attractive that it never bothers me anymore!)
I feel about the same about gravel as I do about wood nuggets.
I’m not a rock person, but I wouldn’t totally
discount the benefits because they do have their place in lovely landscapes.
They can be an asset in high foot-traffic areas.
I like them around flat stepping stones.
I really admire large stones as a groundcover or liner in areas which are prone to drain and wash out during rains.
They prevent further dirt erosion, don’t wash away, and usually stay where you put them.
I see stone groundcovers often in commercial landscapes.
The rocks look kind of hot during the summer, and I wondered if they build up heat and dry out the stems and leaves of nearby plants.
Maybe they’re better as companions to shrubs than near flowers.
Stones appear to conserve soil moisture (until it gets really hot in direct sunlight) and prevent weed growth, if they’re applied thickly enough.
Our son and daughter, who live in Nevada, have front yard plantings that are set off in small white gravel, and it works very well with their drought-hardy shrubs in that hot, arid climate.
As you can surmise, mulch selection is a matter of personal preference.
Each material has its advantages and disadvantages.
A helpful tip to remember is that
before
you spread any type of mulch, take the time to amend your soil with things to keep plants nourished during the growing season, like compost, and a little store-bought fertilizer.
Some people like to add black plastic or landscaping fabric to the ground before piling mulch on top.
Their good intention is to suffocate weeds, but plastic doesn’t allow the plant roots to breathe and receive much water.
If you use the plastic, punch holes in it.
Unfortunately, the holes will allow in weed and grass seeds along with the rain you really need.
Finally, make sure mulching materials are not touching plant stems, trunks, or the wood on your home.
Besides trapping damaging moisture, this promotes insect infestations, including those we fear the most – termites!
