Botritis ???

[prodigal gardener]

I have some sort of greyish fluffy stuff on some of the plants in my greenhouse I think it might be Botritis (not sure of the spelling!) when I touch the leaves it sort of flys off all over the place and I'm thinking thats probably not good ??
How do I get rid of it?

Hello Karlslass - Try to remove any yukky plant debris from your greenhouse as the Botrytis will just spread.
If you don't mind using sprays a systemic fungicide could be used ( I wouldn't use it on edible things though).
Do you have heating in your greenhouse?
Sometimes if the air isn't moving about it can cause problems - on mild days try to ventilate your greenhouse .
Hope this helps - Pam

Thanks Pam, Been out today and had a good old fashioned clean up in the gh. I do have heating but its not cold enough really so I've not bothered with it yet this year. I have thrown out the worst affected plants (a couple of pelargonums) pots and all ! I have left the windows and door open today as it is quite mild here if very damp. Heres hoping I have nipped it in the bud

I hope so
Just being nosey but what plants are you overwintering in your greenhouse?

[prodigal gardener]

Erm..... couple of Fuschias in small hanging plastic pots, Nectarine tree, Olive tree, couple of small Acacia (?) trees. Got some Calendula which got too leggy in the house. various lillys, Karls bonsai trees, an aspidistra from Mum thats in the ugliest pot you have ever seen ! Couple of Margurite type things and I have some succulents in a little glass case. No pelargonums now cos I binned em! Oh and some sweet pea's I planted and cant bear to put outside in case they die!!

If it helps I always get some botrytis on my overwintered plants in the G/H. I tend to be quite laid back about it now. I remove the affected leaves (and any other dead growth) regularly and the plants are usually OK in the Spring.

Geraniums are the worst affected but they survive to give me cuttings for next year.

The advice you've been given is sound tho'. Cold damp still air encourages it. I ventilate my G/H whenever possible (occasionally, when I'm particularly forgetful, overnight with the heater on!) I don't recommend that tho!!

Botrytis Grey Mould affects Plants if conditions are cool humid and still increase ventilation and mist also reduce watering, if on compost remove top part and replace, if plants are not too badly effected you can remove some of the bad leaves if bad get rid of the plant.
Hope this helps Karen

Hope you have not lost too many plants

It is usually a case of keeping watch, taking off affected leaves, sometimes a stem, if the plants were quite strong when they went in they usually grow away in Spring.

I have to keep a regular check in the GH and PK. As had been said ventilation is key, I took this advise some time ago and it has helped tremendously. I have the window open and the door by about 2" all the time, other than if it's blowing a gale or we have a run of several days below 0, then the door is shut but the window remains open, I do have bubblewrap in the roof so that keep some of the warmth in.

Check as often as you can for any leaves that fall or young plants that die off. I check at least every couple of days and just go round looking and removing bits as and when. Also don't have plants to tightly packed in, they all need thier bit of space so air can circulate around them.
