Evergreen Jasmin - Red spots

Hi Guys,

I planted a jasmin in a large pot a couple of months ago, apart from a brief attack of aphids it has been doing well and starting to cover my trellis. Now I jhave noticed lots of red spots on the leaves and the new leaves ar a bit yellow. I assume it is too wet, but I am not sure what to do in this weather (I am in the North of England)

Any ideas?

 

Hi Ellie, if these spots are raised and are also showing underneath the leaves then the odds are that your Jasmine has rust. This can be treated with a systemic fungicide. It will not make the
spots go away but will kill the fungus, and more importantly, the spores. David.

 

Hi David,

Thank you for your reply

They are not raised and don't look like a disease, but more a change in pigment. The plant is close to flowering and I am wondering if it is some sort of difficiency caused by too much water? I did notice on Sunday, a few in the nursery where I purchased it from had the same red spots

Cheers EGW

 

I think your right that its a watering problem. Some plants will develop dark red pigment in the leaves when under stress - and the yellowing of the new leaves sounds like the roots are in difficulty.

Ideally with a waterlogged plant, the sooner the sodden compost is removed, and it planted in dry, well drained compost the better, but from the sound of it this may not be possible, so

Stop any watering, protect the plant from rain, and if you can raise the container on bricks to allow the wet to drain away. Or even tip it on its side

Keep you fingers crossed.

Thanks fran! I am hoping dry weather for a few days will do it good. Stupidly I plastic lined my pots (iwth drainage obviously) and planted them up with moisture retaining compost and mulch on the top to protect from drying out. Obviously wasn't expecting the wettest month on record! It is in a large tub and is trained into the trellis so I am not sure if it would be possible to repot - I also have some bedding plants in the pot so it would be a real hassle. I hope I don't lose it as it is about to flower soon
