I am doing an article for my club newsletter on using pine cones and
needles as mulch. I need some help.
One web site stated that pine needles don't attract termites. Is this
true of pine cones?
One web site stated that pine needles also make a good barrier against
According to Texas A&M University, pine needle mulch also prevents
soil-borne diseases. Why?
One web site stated that it's the pine pitch which is acidic and not
necessarily the needles or pine cones. Once the needles turn brown the pitch
has dissipated. Is this true? I actually want acidic cones. Our soil and
water is alkaline.
Pine cones and needles can be put in between irises but not on the
rhizomes. Is this true? Anything I should worry about? (we usually don't have
to worry about snow and sub-zero temps so we do not cover irises in the
winter in southern NM)
Flammable? Can you use them next to the house? I don't see much resin on
my pine cones. Are needles and pine cones any more flammable than regular
bark mulch? Does it depend upon how fresh they are?
The advantages include:
. Insulates tender roots from temperature extremes.
. Protects against digging cats and dogs.
. Keeps soil moist longer (I live in the desert).
. Encourages water infiltration into the soil and reduces runoff.
. Eliminates erosion caused by rain-splash impact and high winds.
. Protects against soil compaction by reducing the rain impacting
directly on the surface.
. Can help make the soil more acid.
. Provides some nutrients slowly over time.
. Pine needles stay put and will not erode.
. Does not have to be removed. Just add more.
. Better than putting it in the land fill.
Any more advantages?
