I bought my Bettina Ivy last Sunday. I think the big mistake was that I brought it home on a very cold evening, it was about 14F and I didn't put it in any bag or box to protect it from the cold. When I noticed on Monday that the tips of some of the leaves were dry, I thought it was due to cold burn. I checked Google and some resources mentioned watering the plant to help it. I did so and sprayed it a little with neem oil solution to prevent fungus gnats. Since Monday, every day I have found more and more leaves with dry tips or completely withered. Please help me save him!
