i bought these plants and set them out. they did really well for about 2 weeks then they just stopped growing. now they appear to be dying. i haven,t seen any bugs on or around them. here is a picture of what they look like. they started wilting like they needed water but the ground was wet. it had been raining. they started wilting a little before it rained and just got worse. i have never seen this before the leaves are turning brown, and getting crisp. the white on them is poison i put out thinking maybe bugs were killing them but i dont think that is the problem
