Hello Sally,

I do hope that Lee picks up on your question as he only does organic.

As far as I can recall rust is fungal and is caused by the foliage sitting there with to much moisture present.

Therefore my thoughts are, remove the affected stems and get rid of, don't compost.

Water your roses at soil level, and just mist the foliage doing this in the morning, thinking about it, if one waters in the evening, leaving water on the leaves, and then one gets a heavy dew, there's a lot of water sat on the plant over night.

Worth a try please let the forum know how you get on.

I sure Lee will have the definitive answer.

Hi Sally,

Thanks for your question on rust prevention on garden roses. Rust can be a real pain as it reduces the ability of the rose to photosynthesise weakening the plan. It's a fungal disease that spreads through rain and wind. Nipping it in the bud early doors in the best method.

Removal of the infected leaves is vital and disposing of them as Bob says without composting. Watering from the base can help and make sure there's sufficient airflow. Often rust comes from wet shady spots where airflow is poor.

A good liquid feed once the leaves have been removed with something like Comfrey tea will help give the rose a boost to hopefully recover. Rust usually isn't fatal just slows, prevents and deteriorates the roses flowering potential that's all!
