hippeastrums and rust
| | |
Posted by annie_____ RELAX! It’s QLD (My Page) on Wed, Apr 19, 06 at 4:36
I've got several dozen hippeastrums which have been ruined by what I believe is rust. The leaves develop red streaks which eventually kill the leaf.
Is there a cure?
or should I just bite the bullet and toss the lot out? (which I have to tell you is really going to hurt!!)
I actually want to change that garden over to an all-rose garden.
So....do I go out buy some bullets?

Stagonospora curtisii, "Red Spot" "Red Blight". It won't often kill them but can disfigure the leaves, make flowers contorted, weaken flower stems. There is no actual cure, there are some controls but it would take several pages to tell you.
They won't infect your roses, so take a deep breath and deal with it later.
Meanwhile your bulbs will be starting to go dormant soon anyway, so cut off all the affected material now and dispose of in the garbage. |

No No bullets can leave messy results . As the other posting says , it can be very disfiguring for the plant, ( but seldom fatal) and therefore disheartening for the gardener . My experience with it has tended to show that it affects leaves that have somehow suffered some trauma ; eg, snail/slug damage , cracking or bruising from wind damage, people or pets brushing against the leaves etc. I include spraying my hippies, when I spray my roses for blackspot and powdery mildew, with [ I have just taken the torch and trekked out to the shed to find the stuff to try and make sure I could get the spelling right, and yep someone's shifted my stuff, so here goes as a guess] triforine? and it works well.
My mum, just before she died in the late 90's, was an avid collector and breeder of hippies, and by the time she died, she had a few thousand of the things. This is some of what she used to do... when repotting or splitting up clumps, the bulbs used to get a soak in a bucketful of Mancozeb solution; they were potted in a mix of 2/3 chook manure to 1/3 potting mix and had regular top ups with a pelleted chook manure like Dynamic Lifter and were liquid fertilized with a potash rich fertilizer like Phostrogen. She always said that they were really gross feeders, and if they were really healthy, they were less susceptible to the fungal damage. They also used to get watered (she did it with a watering can) with a fungicide that started with a Z ( can't remember) or one called Fongarid and also a bluish coloured one that looked like it was copper based. This she said had the added advantage of discouraging snails and slugs, they don't like the copper apparently.
Don't give up, they will fit in with the roses and their spray and feeding regimes... good luck ... Rosalie |

| I never thought of leaving the hippies there with the roses. I rather thought the hippies liked being a bit dry? |

Annie if they were growing in my raised garden bed of roses it would be dry.
As now the only wet part is around the stakes my standards are tied too.
Guess who watering them and he says "Why waste water" ....Cheers..MM. |
