Hi ,

I have very little gardening experience , and none in growing citrus .

I have a lime tree i planted about 3 years ago , it has never flowered or produced any fruit . I have noticed over past 2 years maybe that the leaves are being eaten off , i dont believe they are falling off . Entire branches are being stripped as in photos .

Ive researched miner leaf bugs and have 2 leaves that appear to have them , but only 2 . There are these fly things on bottom of leaves , i took this photo about 8 am . I have no idea what i am really

talking about LOL but do need help please

Hi Floridalime and welcome to NGA!

I'm no expert but your tree looks like it's infested with Asian Citrus Psyllid and it also looks like you might have Citrus Greening aka Huanglongbing disease as well. If you have other citrus plants that are not affected, you need to dig this guy up and destroy it immediately. No fix and no cure.

Here is a link that describes both the Asian Citrus Psyllid and Citrus Greening .. it's about California Citrus but applies to Florida as well.

"The Universe speaks in many languages, but only one voice. It speaks in the language of hope; It speaks in the language of trust; It speaks in the language of strength, and the language of compassion. It is the language of the heart and the language of the soul. But always, it is the same voice. It is the voice of our ancestors, speaking through us, And the voice of our inheritors, waiting to be born. It is the small, still voice that says: We are one. No matter the blood; No matter the skin; No matter the world; No matter the star; We are one. No matter the pain; No matter the darkness; No matter the loss; No matter the fear; We are one. Here, gathered together in common cause. we agree to recognize this singular truth, and this singular rule: That we must be kind to one another, because each voice enriches us and ennobles us, and each voice lost diminishes us. We are the voice of the Universe, the soul of creation, the fire that will light the way to a better future. We are one."

I agree they are citrus psyllids, and the tree does look to be infected with Citrus Greening disease - that yellow mottling of the leaves is a sign. Sadly, there's no need to dig the tree up and destroy it now. Most citrus trees in Florida are infected by now, and since the disease is transmitted by the psyllids, it's next to impossible to stop anyway. The only fix in Florida is to develop varieties of citrus that are resistant. In other states where the disease is not as widespread, removing infected trees may still help somewhat. But not here.

Spraying the tree with a soapy water solution will at least kill off the psyllids that are on there. Use about 3 teaspoons of dish soap per gallon of water and spray the whole tree, with special care to get up underneath the leaves. I've kept a kumquat tree alive for 3 years so far, spraying it once a year with a solution of dissolved aspirin. I even harvested a couple of kumquats this year. I also spray it with the soapy water solution about once a month. Fertilize 3 times per year, spring, summer and early fall with a fertilizer specific to citrus.
