Its been hot lately and the sun is also changing I have noticed. I am wondering if this is sunburn. These traps were very healthy now recently the sawtooth looks fried and the wacky had traps turning yellow and then black and you can easily pull em off the plant. I water a little everyday not too much just enough to keep the sphagnum moist. I noticed the cups are hot when i touch them. they get sun from about 8:30 am to 4:30 pm. I do not leave in standing water because the directions that came with them said not to. I noticed alot of my traps have kind of stalled on the growing with the heat. Normal?
they are sun burnt but there really is not much you can do now. all the new growth will be acclimated to the intense sun. also if its really hot out say 90 plus degrees, i soak my plants until the water poors out the bottom. the roots stay cooler i find. dont worry about root rot when its very hot and with all that sun which is almost 2 hours more then i give mine they will dry up fast enough so thats a non issue. if its in the50s and 60s with clouds for days on end then just barley moist is fine. i see you live in Delaware co pa. i live in southern Montgomery co pa so not that far away. the next week will be 90 plus and i plan of soaking the crap out of my plants every morning. the last thing you want is the moss to dry out almost completely which will over heat the roots and the plant could burn very quickly which could kill the plant.
