Hello,

Another pick up from Bobby. This pyra has shorter, fatter leaves and also some kind of grey/white fluff that seems to be present on the leaves. Almost like dust. It has been completely watered off then comes back next day so I think it is part of the leaves or something. It is a different species of pyracantha. Haven't seen the berries so may not find out till next year. Online research says it looks like "Orange glow". Suggestions welcome.

Another one to just grow for now, will assess during winter although it won't drop leaves so will be more difficult!
I'd like to fill in a bit of space around the roots, in its pot. Especially considering it has a layer of moss on it, but not too much as to hide those gnarly roots.

The white fluff you describe sounds like it might be a fungus. Try a commercial anti-fungal spray, or dilute peroxide.

Yeah I can see how it sounds but I don’t believe it’s anything harmful. Bobby would have noticed if so, I believe :). Either way, they’ll get a fungicide spray tonight or tomorrow as part of my usual rotation. Got a pesticide spray this morning.
But thanks for suggestion, without having seen and touched the leaves myself, I’d have suggested something bad too, based on my description :)

Well, what we will see.. only problem with evergreens, never see them naked! Thanks :)



Thanks, yes good looking pot.
I defoliate so I can get in and wire, and set structure, they do shed leaves eventually anyway.

Hmm I’ve never thought of defoliating my pyra. Defoliating during winter, no affect on health?
Like defoliating a maple for example, in summer, would impact its health.
But as it’s winter I guess this can be done, regardless of its health?

A treatment may be in order. I don't think it's a horrible thing just needs treated.

ah ok see what you mean, i actually thought that was some sort of salt or calcium deposits from watering above. seems to rub off by massaging a leaf with finger n thumb. if its a fungus then rose clear is fine, the fungicide one.

I would not defoliate any tree if it were in poor health. But I do defoliate my pyracantha late winter and wire. Just keep in mind that my winter protection scheme is very skewed towards safety. I'm sure you could defoliate in spring and it'd be just as effective.

this is my other Pyra, i havnt even bothered to spray mine, as i say just looks like a little water has dried on the leaves and left a white residue. trees are extremely healthy.
here you can see a before n after ive rubbed the same patch of leaves between my fingertips....
no harm in using a bit of rose clear as preventitive measure

I wouldn’t in spring, just if I can get away with it in winter it’d help a lot.. but I’d rather build up a familiarity with a tree first before I make assumptions about its health.

If there’s the option to do something which depends on it’s health, and I can’t 100% guarantee it’s health (at least based on my own conclusion), I’d rather wait a year.
It’s early days so not too ramified. I’m sure I’ll be ok this year to get a good look :)

Yeah I thought the same Bobby but when it then came next day + these posts, it made me rethink.
I’ve sprayed with fungicide yesterday anyway, so will see how it is in a week or so. In 2 weeks it’s due next spray which will be rose clear.
Good learning experience on a more harmless fungus :).
Thanks all

I've rinsed off the fungus...and waited for it to dry then treated. Seemed to help remove the issue quicker. I seen it on my exposed root crabapple.

Yeah I was in a bit of a rush last night, I had watered everything then applied fungicide when all was still wet.
I might apply rose clear (different fungicide) to just the new trees, when dry.

You water at night? I try not to... because of fungal issues seem more revalent when watering later in the day.

You can kinda see the fuzziness on the leaves.
This first pic I rubbed off the first half of the leaf.

Could so easily be mistaken for dust or sawdust or just maybe even calcium build up.

I water when I can. I do it daily but sometimes I'm not home till late.
Id prefer not to think what you say is true or else it would ruin my life :)
