If it isn't the effing needles, it's the effing sharp seeds or the
effing sap on parked cars.

The City won't take out "healthy" trees. Whoever was the
"forester" that put them in, could be 100 years? (I wasn't there
g) didn't know much about species.

(Ex: He put in a variety of Ficus that has GIANT above-ground
roots that wreck sidewalks and trip people.

ID'd as Indian Laurel Fig, Ficus nitida
Scientific Name: Ficus retusa ssp. nitida (Th.) Miq.
Synonym: Ficus microcarpa var. nitida)

Back to subject: Those effing needles obscure plantings and
clutter up my arrangements.
They do not compost well, or at all, so I gave up and just rake
them out and put in
yard waste bin..

This is a huge PITA, so I wonder if I can just apply small nugget
mulch right on top of needles. Would presence of needles under
mulch interfere with function of mulch: to help conserve water in
our drought, as well as aesthetics.

Tree supposedly originated in OZ. Hope somebody has an educated
opinion on whether it's safe to mulch over needles.

I had an opoportunity once to receive a pickup load of pine
needles. I jumped at the opportunity, and they make great long
lasting mulch, that does an excellent job of keeping weeds down. I
imagine yours would do similarly.

Interesting! Trying to connect this in my mind with my experience
in composting.
Needles never DID compost. Is this good or bad for my objective of
mulching over needles? Sorry for sounding opaque g


It's good if you don't want to have to keep adding mulch. If you
goal is to add nutrients to the soil, the needles could slow that
down a bit, but I wouldn't expect much slowdown because the added
mulch will speed up the composting of the needles by keeping them
more moist.

Thanks; that helps clear my so-called mind. Goal is NOT to add
nutrients to soil.
Goal is to escape nuisance job of clearing needles before applying
compost.

Will go ahead & apply compost over needles. Fate of the Universe
hangs not in balance.
However -- eternally curious -- will leave a control area as is,
namely, remove needles before applying compost, to observe results.

Could there be a PhD dissertation in this?

Definately in this case. By the "Piled Higher and Deeper" definition.
