Comments (8)Marco, if you want to spray for CLM, you'll want to combine Volck oil (which is one of the hort oils) and Spinosad. Spray every 3 weeks during your CLM season. Or, you can use Bayer Advanced Fruit Tree & Vegetable Insect Control about 2 weeks before CLM hits, then treat again in 6 months. Can't speak to Citrus Canker, but it does look like what I see in photos when I search for it. I've included a link below, and I would contact your local ag agent for a positive ID. And, I believe you are referring to Citrus Greening disease, or Huonglongbing (HLB). Being in Florida, again, contact your local ag agent for a positive ID, since it is so prevalent in Florida. It does not look like HLB to me, but chlorosis of some kind (iron, zinc, manganese), which would mean apply more citrus fertilizer and make sure it has a full complement of micros as well as your NPK macros. Cheleated micros make them available to your tree to take up. You can find cheleated micronutrients or minerals at your better garden center. Patty S.

Comments (7)Rob, Mrtexas is correct, classic sign of freeze damage to the bark and possibly the cambium. It won't necessarily show up until the affected areas begin to swell with more fluid and begins to expand, as your weather warms up. So, I would suspect the damage was done, and as your weather heats up, the cracks are expanding. I would check with your local extension office about how to protect young fruit trees from frost damage. If you can preserve the trunk above the graft line, even trees that have lost their entire canopy can come back, as long as the trunk is undamaged. To protect the tender trunks now in the summer, you will want to paint your trunks and exposed branches with regular flat, white latex house paint diluted in 1/2 with water. That will help to reduce sunscald as well as protect from boring insects. Patty S.

Comments (1)Letting citrus bear when young is a bad idea, the trees just don't have the reserves in case there is a problem. Some will cite university studies that state the opposite but that is foolish. Homeowners seldom give the trees the expert planting and care that trained horticulture experts do. I'm in Florida also and some parts of the state have been dry like here but other spots have been drenched. What has it been like where you live? Have you fertilized the tree? How deep did you plant the tree? With citrus you should be able to just see the tops of the roots at the trunk. Is the tree mulched? When you planted the tree did you just put it in the sand or did you amend the soil? Amending the soil and heavy rains that last for days is a recipe for disaster and is why on our sand the soil should not be amended. Just need some more details....See MoreHoneybell problems
Comments (3)Cathy, load up photos for us to see. Be sure to include close up photos (clear ones) of the leaves and the fruit. Cut the fruit in half and snap a pic of the halved fruit as well. You can add photos by using the "Image file to upload (optional):" field in the response section (just look above where you type, you'll see that field and the "Browse" button). I also answered your private email to me, but you're much better off responding to the forum than to me, privately. We do have several Florida forum members, and they are probably better equipped to answer your specific questions than I am, being that I live in California, and our disease pressures and growing conditions are somewhat different.
