I just purchased a Bald cypress from the Bonsai show last weekend. I brought it home Sunday, it was very dry, I’ve been watering it every morning. By evening the soil is moist. I’m guessing it hasn’t been repotted in years. Today I noticed the foliage is drying out and falling off. I’m concerned that all the foliage will be gone in a week or less at this rate. I have it in 50% shade. What can I do help it?
