Hello, I’ve got a problem with my 1year avocado plant. He never had growth problem, since 2 months ago. In september I put my avo plant inside to protect her from cold, I reduced irrigation to 1 time a week, but after 2 months, her leaves started being brown. I checked her roots seeing the were white and strong,, so I decided to reduce more the amount of water. After 20 days the plant didn’t show progresses, but also the upper leaves has become being brown. I spotted some mosquito near the ground( don’t know if it means something).

What can I do to save my plant?! :(

Please answer me if you know!

Thanks, Beatrice.
