Help please

Hello i overwintered evening primrose in my greenhouse, I sowed them late last year now I've noticed an orange powery substance on the leaves. Is it dangerous to the new flower seedings I've growing there

 

Hi Kerrygirl , if it's a powdery substance it's probably Fuchsia Rust.
Evening Primroses are a member of the Fuchsia family and the disease is readily spread between them as Evening Primrose is the main carrier. You need to dispose of any plant infected , especially if you have any Fuchsias. Other members are Clarkia and Godetia.
Personally I don't grow any Evening Primrose as I grow Fuchsias, Clarkia and Godetia.

 

Thank you KFF for replying I will try to get something for them, thanks again

 

Hello KFF, sorry for the short reply earlier. I have 26 plants, I better dump all of them. They are all infected. I'm just getting used to my greenhouse. Is it possible to get a list of plants that dont carry a fungus

 

Don't panic!!Terms that folk use can sometimes be a bit confusing. No Kerry, I'm not have a go at you. Actually my eldest daught is named Kerry.
Now then. Evening primrose is an outdoor plant, so your reference to growing it in the GH, I you refer to young plants you have raised from seed.

Having discovered whatever it is. Don't panic. Provide the roots are good, then simply cut down the top growth. This will have a similar affect to pinching out. The wasted material should be burned. A general spay/douching of a fungicide will help to get rid of left over infection. Hope this helps.

PS. For fuchsia growers. Rosebay Willow herb is probably your worst enemy.

 

Hi mike thanks for replying but unfortunately I did panic, i dumped them all today, broke my heart but thought i had to

 

Thank you JWK, yes thats an option

 

Hi @kerrygirl what a shame...don't be so quick to dump.. as this year alone as learnt me a lesson with GC members advice on how to protect the plants with these bad winters.

Plus you'll always get members step forward with different opinions ..then it's how you react to the sound advice they given

 

I hear you Gail 68 thank you
