I've been growing a Cape Sundew I bought online for the past month and it was doing really well at first. It was very tiny when I received it bare root, so I planted it in some peat moss perlite mix, put it on a water tray, and put it outside. It took a few days to acclimate, but then started to grow like crazy, some of the older leaves dying off and new ones sprouting like mad. The new leaves that came out started developing a lot of healthy looking dew, and everything looked good!
However, for the past two weeks its just been overcast and raining almost every day, and the plant isn't really growing as much any more. The "new" leaves it grew that became big have stopped producing sundew and are starting to turn reddish. The newest big leaf it grew was producing a lot of dew and looked nice and healthy, but now has two small holes in it!
I just leave it in a tray of like an inch of distilled water (rainwater nowadays since it rains everyday), and I empty the tray out of water since it keeps on raining nonstop.
Am I doing anything wrong, or do I just need for the sun to come out again? Should I stick it indoors or something when its raining, is it getting overwatered?
