Black spots on leaves

Does anyone else have this same problem?

On walking around the garden today leaves of most of my shrubs have black spots.

Think it must be to do with all this rain we are getting,it has rained for weeks now.

 

hi kath ive got the same thing but only in the garden my pots are all right

mary :confused:

 

Scotkat try 2 month up hear in the north west, ive got the same problem with my roses.

 

Same problem on my shrubs, horrible isn't it

 

:( When all should look so lush and green ,these black spots are even on my hydrangea and it is in full bloom of blue flowers ,I feel like cutting all back to base.

Sad to see garden like this.

 

Hydrangeas often get black spots on the leaves without there being any fungal cause.
As for the other shrubs, well blame the Clean Air Acts which got rid of all the sulphur in the air which killed off a lot of the fungal spores (and people too!).

 

Agree with you Pal, we don`t even have a decent fungicide to use anymore ( Tumbleblite ). David.

 

Cheshunt compound is a decent fungicide a few more on this site.

I sometimes get leaf spot on my yuccas and chamaerops humilis which is caused by too much water and have to cut off infected leaves and spray with a fungicide. But in this weather I think most plants are getting affected, just far too much rain which we cant do much about, unless we all buy huge gazebos to cover our gardens!! hehe :confused:

 

Walnut, have you tried that Systhane Fungus Fighter, I have, It states its for all ornamental plants and fruit.
It leaves everthing looking like its been dosed in grease and it stinks, (I think) like chip fat, must be a by-product of the fish and chip industry. :D
Dithane is not so bad but it leaves white spots on every leaf, but at least it dont stink.
Nimrod T was my favourite along with Benlate.

 

Not tried Systhane Pete I will give that one a miss, Benlate is good.

 

Merrymeet one and all, Have any of you heard of NEEM OIL? I use it for blackspot plus other things in the garden. I buy it from the internet and its biodigradeable too. Have a look on this website:

www.theneemteam.co.uk

They are based in Wales.

Neem Oil works for me and i have allsorts of plants and herbs.

Goodluck

 

Willow 13, I have heard of neem oil in the past but was informed at the time that it could not be sold for use on garden plants as it has not been cleared as a pesticide in the UK.
Has this been changed then?

Walnut, Benlate WAS good< you cant get it anymore I dont think.

 

No Pete you can't get it any more it was banned in 1997 caused birth defects in pregnant women.

 

you can try a spray bottle with ur dish soap to spry on ur plants it will help
