hey all, hope your winters are going well! i've been quietly tending to my growing little collection, and for the most part, things are going well. for instance, my d. coccicaulis are fat, dewy, and flowering themselves silly: my capensis (of course) are going nuts as well. here's the latest photo of the *army* i am creating: some of my sundews, however, aren't doing so well. here are a few shots of d. tokaiensis and d. spathulata: i repotted the first two a few months ago, and the last one are plants i've grown from seed. all of them are more or less dew-less and just don't seem to be thriving (although the first tokaiensis there is still throwing up flower stalks all over the place). the weird thing is, all of these plants are under the EXACT same conditions -- same soil, same light, same watering schedule, etc. any thoughts as to why some of my plants are doing so well and some of them aren't? i thought maybe they didn't like being repotted very much, but it's been months now and that seems like a long time for them to be set back like that. i just don't know what else could be wrong. anyone?

My spathulatas also seem to cycle back and forth. They always come back though. And if they don't it's so easy to propagate them it doesn't matter. Just grow new ones.

definately damaged! I find when I transplant, the dew is gone, but any new leaves since should have dew... By any chance was this a new bag of soil? Otherwise start looking for some kind of mite or thrip.. Sib

The first picture of the d. tokaiensis shows the surface of the soil covered in a white substance....I'd buy some Safer's Defender and spray the affected plants once/week till its gone. I've used it on my cephs in the past (not needed now as got rid of the problem). It's called powdery mildew i believe.

thanks for the advice everyone. i think i posted about the white crap before and someone told me it was nothing to worry about and wouldn't bother my plants, so i kind of stopped paying attention to it i wondered whether the plants' condition was just a cyclical thing like lloyd/insectivore suggested, but i was worried something more damaging was going on. i'll try to get some safer's defender and see what happens. do i just use it as directed, or does it need to be diluted or anything? insectivore -- i thought you'd enjoy seeing the coccicaulis since those are the same plants you sent me last may. they have sure grown, haven't they! i am so proud of all their fat globs of dew.

so, i haven't had time to get to canadian tire. obviously something is wrong though because i think my plants are getting worse. i am going to pick up a new bag of peat and some safer's defender and try to start fresh.
how many people have used safer's defender on their sundews? i think a few people on here have mentioned it being hard on the plants. should i use it as directed on the bottle or do i need to do anything differently for them? does anyone recommend any other products like this that i should pick up while i'm at the store?
thanks, danielle

Sundews don't like stuff on them. It sets them back, although they do recover.

canadian tire did not have safer's defender. i did pick up some "green earth garden sulphur" fungicide and "no-damp" fungicide. i am not sure which, if either of these is more appropriate to use on my sundews. the first is sulphur-based, which i would assume makes it similar to the safer's defender. the second has "oxine benzoate" as an active ingredient and seems to be mostly aimed towards seedlings, but i seem to remember the name being mentioned on here so i thought i'd pick some of it up too.
should i try the garden sulphur? would i be correct in assuming it works the same as safer's defender? should i return the no-damp or is it something i might also find a use for?
any help would be appreciated. thanks so much. danielle

The No-Damp has its uses. I think the solvent in it might really ruin the sundews for a while. Try 1/10 the recommended strength of the sulphur on one, out of the way leaf and observe it for a few days.

i have set up two "test" trays of the affected plants, one using sulphur and one using neem (which i've heard is an effective fungicide). i am a little unsure about the mixing ratios/methods of application/frequency of application, but i am winging it i guess. set it up on march 11, so far nothing has changed really. the problem seems to be getting worse/spreading though. my coccicaulis are starting to dry out around the edges (i have since isolated everything that looks affected, but it's probably a little too late). i am worried that all my plants are going to die. i would repot them and try with brand new clean pots and fresh peat, but i am worried that even the act of repotting them in their fragile state would be enough to do them in
