My small avocado tree dying!
Hello everyone, I live in Broward county, South Florida.
I bought 10 months ago a 4 feet tall Miguel Persea Americana Avocado tree (HomeDepot) and I planted it in my backyard (Full sun exposure). It kept the same leaves, no new growth until about 3 months ago, it lost all its leaves and about 6 weeks ago it began to bud again, getting many leaves growing out of the green stalk.
Unfortunately, since a month ago I started noticing that the top buds were dying, and now at least 30% of the top buds/leaves are dying. I believe I saw a bit of grayish dust on the buds. I dag around the roots to see if maybe I was watering too much but it seems to be fine and the roots seem to be healthy.
Does anyone knows how to stop it from dying? Any ideas? On the same part of my backyard I have a Cogshall mango, a Muscadine grape, a Guava tree and
a Honey Bell orange that are doing well, same watering practice, etc.
Thank you in advance.
