Cape Sundews dying?
I have two sundews that are not doing so well all of a sudden.
Initially, my young, and newly obtained, Cape Sundew Alba started having ever so slight wilting on some of it's leaves -- just the tips, and only for it's newest few leaves. It created a flower stalk for the first time right before this happened -- and It also stopped making dew at about that time.
It has new leaves coming in, but, they are coming in very, very slowly. In fact, they might have stopped growing alltogether.
Initially I thought this was just a problem with that particular sundew. It is in a very small (3") pot with a 4" "deep" saucer, and I am watering it with the tray method, and an occasional bit of water directly into the pot.
It flowered before/during all this, but about halfway through the chain of flowers they stopped opening.
However, the same thing is now happening to my first CP, my year old Cape Sundew. It has lost all dew on every single leaf. It has no new leaves coming in, and I noticed a baby leaf that was dark black -- it had died before it had grown much more than 1/8th an inch. And a few of it's leaves have turned black and brown on their tips.
It has also flowered recently, in fact, it has a stalk still up with new flowers, however, they seem to be opening slower than before -- before I'd see 1 or 2 a day open, this one has had this same stalk sitting there for quite some time now.
I not-too-recently (about a month ago) switched it to a new 5.5" pot and gave it a deep dish saucer, which is how I've been watering it.
In short, it's the exact same symptoms and setup now as the other plant.
A few oddities -- the bigger sundew's saucer water turned yellow-brown, but I flushed the water through the soil in the pot instead of just filling up the saucer like normal. At the same time, I noticed a thin, oil-like film over about 1/4th of the water in the saucer -- I have since switched saucers and used a clean rag with a tiny amount of hydrogen peroxide to clean off the pot sides before refilling.
Other changes in their environment coincided with the repotting and switch to saucers -- I got a few more plants which required I move some things around -- so the big sundew was moved about 6" away from the main window. The smaller sundew was moved up 1 shelf level, but should be getting the same amount of sun.
Does this sound like a sunlight problem? Or perhaps contaminated water? Or maybe even some form of pest? Could it just not like the "wet feet" in it's current setup?
The temperatures lately here have been dropping into the 50-60 range and have been hovering around the 80-100 range during the day. In theory, I could put them outside but when I did that before, the Alba sundew hated it and lost all it's dew, rather quickly -- although that might have been a combination of the 30-40 degree nights and acclimation the last time I tried it.
