Hi, is the tree indoors right now? As far as I know, citrus will grow larger (even huge) leaves when it is not receiving optimal lighting; aka “winter leaves.” Nothing is wrong, your tree is just adjusting to lower levels of light :)

Hi Kelley,

Well, it is outside now but it was indoors for about 1 month due to weather. I am in Las Vegas and our winters can be mild but we did experience a cold spell. Plus we recently moved and the backyard doesn't get 8 hours of sun, due to trees. We will be moving the end of the year, so hopefully it will do ok before that. It will only be getting about 4 hours of direct sunlight. Thanks so much for your help!

Very common on grapefruit trees. Nothing to concern yourself with.

Thank you, Silica!! This little tree is very special to me so I worry about everything. :) I give it worm castings occasionally from my worm bin, so I was worried it was getting too much!
