Help! Why Is My Avocado Tree Dying During Winter?

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

Avocado Tree - leaves turning brown

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.

    Hi, I’m sorry, but I have no idea how to ask questions on this website. I have an avocado tree as well and she’s about one years old. I brought her inside for the winter and she got an infection of aphids and it killed all of her leaves and she was left with just the stick. Then she began growing more leaves, but they began to die and I have no idea why, because I got rid of the aphids. Then, she started turning black and it’s slowly spreading down to her trunk, and while this is happening, she began trying to grow more leaves, but they died once again. I’ve tried everything: Ash, Moisture, fertilizer, flushing(my cat pooped in it twice), and nothing’s working. Is she too far gone? Or is there any hope left for my once beautiful and flourishing tree? Please help, Cory

  2. Cory,

    Depends. Since I can’t see the plant, I am going to many an assumption that the pant is probably too far gone. However, you might give one last thing a try – cut the stem back to the green part. Then wait and see if the plant continues to put new leaves on. In the meantime, don’t do anything but give it water when needed. Good Luck.
