I save coffee grounds from OP (along with my tea leaves) for roses and
other decorative plants. He says banana peels are also good for
roses.

Trying to save myself misdirected effort, what is NG opinion:

Need to scratch in and water coffee grounds? Or bury? Or just leave
on surface?

Yes, Hypatia , glad to help.
You can use as mulch. The only reason to bury it would be to jump-start
very bad soil for a garden. Usually, you will bury nitrogen sources,
because the proteins breakdown releasing ammonia, which is a gas that
will dissolve into water.

When apply -- in rose's annual cycle.
Ideally, just before it pushes in the spring, when it will need the
nutrients the most. But they aren't like nitrogen, that will encourage
plants to waste energy pushing green foliage while they should be
resting. Or do your's bloom all year round in Santa Monica?

Need to cut up or grind up banana peels? Same q. as above.
Only if your in a rush.

Same q, when apply.
Anytime. Their nutrients aren't going anywhere, unless aided by a
squirrel, or a bird.

TIA for opinion(s)
Nichts zu danken.
