Ask The Plant Expert: Ok, so it's winter, and I put my one-year-old avocado tree inside to prevent it from freezing, but some of its leaves have crunched up and the tips of some leaves are brown. What's wrong with it? What should I do? Any ideas? - Cassy Flower Shop Network Plant Expert Reply: Cassy, It looks like an environmental factor and not a disease problem. When you move a plant indoors during the winter humidity becomes a problem. The heating system in most houses decrease the moisture level in the air. So, you need to increase the humidity around the plant. You can do this by misting the air around the plant with lukewarm water once a day. Your plant may need a little more light as well. If you can move it closer to a light source, I recommend doing so. Hope this information was helpful. Please let me know if I can help with anything else.
