Having a bad season with my snaps..they all get rust disease after one bloom or even before it blooms. Is there anything I can do to prevent or cure the problem. I love my snaps :)
Unfortunately, many are very susceptible. That's why I stopped growing them when I lived in SoCal.
If you use fungicide, be aware that the key is to spray often enough to protect new growth. Nothing, short of removing the affected leaves, will get rid of the disease you see.
I've tried growing snaps (from seed) that claim to be rust resistant. They still get rust, although maybe later than otherwise.
when the snaps get rust, does it inhibit flowering..on the dark leafed ones, you can't tell it has rust unless you look underneath...should I yank all of them out? or do you think they may still bloom a little?
I don't know- mine just up and die from it so I have not planted them for years.
Hollyhocks and snapdragons get it the worst in my garden, and they are two of my favorite flowers. The snapdragons that I grow from seed seem to do better than the six-packs from HD.
KNOCK ON WOOD .... my cluster of Snapdragons were salvaged from LOWES bargain rack....leggy and needing water .... they are going gangbusters with no sign of rust ... hope that continues, as snapdragons are a trip down memory lane for me.
Rust is a drag. I had to throw away a Pelargonium that was covered in it. It had just started to bloom again too. Hopefully none of my others get it.
