Hi. I'm new. Just bought a Eureka lemon and Calamondin tree from Walmart. Similar situation to rudell. They've got the ISD treatmnet tags and are apparently from Florida (from what I have read here). The problem is that the tops of the leaves are coated with a green powder (looks alot like powdery mildew but is bright green). Comes off easily when wiped with damp cloth. From what I've read about citrus greening, the leaves themselves discolor right? Should I be concerned? Anyone have a clue what it is? I will try to post pics if I can figure it out. Thanks!
O.K. I took some photos. First and second one is the powdery stuff, third one is some leaf discoloration after I fully remove the green stuff (should I worry about greening? or is it just the plant was in wrong conditions?) and fourth is a the shell of some bug and the web that was attached under one of the leaves. Any advice on any of these would be awesome! Thanks!
Could be a variety of issues, depending on your source's reputation... however remove the problem areas with a shower of luke warm, soapy water, allow some into the soil, but do not drown the root system.... wipe or remove obvious trouble spots, and hopefully you will have corrected the plants affliction. Keep away from heated air ducts. Bright light source is vital. They should be just fine. If the problem returns, notify your source.
Your tree is fine, and does not have a problem. Due to the quarentine, and the various citrus problems Florida is experiencing, all new trees must be grown inside a screened structure. This is to prevent the tree from becoming infected with canker or greening. As a further percaution, the tree it is foliar sprayed as required by the USDA. Also, the supplier sprays an antidesiccant on the leaves to lower the tree's transpiration rate. This helps greatly, keeping the tree from drying out while in transportation, and retail. You can either do nothing, or since you have such a small tree, you can clean off the leaves, to give the tree a fresh clean look if you wish. - Millet (1,449)
The substance, whatever it is, is quite common on trees from that grower. I wiped it off using a hand towel and some warm water.
Hi Cynthia...don't panick I also wiped the leaves one by one..(good thing it wasn't a big tree) with wet cloth and sprayed with a drop of dishsoad in a spray bottle..it'll go away...wish WalMart would get more ..my ponderosa is doing so well ..I want more lemon trees. keep us posted ..
rudell -I agree -this citrus tree thing is intriguing! I've had a calamondin tree for almost two years now and the kids and I love eating the tiny oranges that are constantly coming so I am soooo looking forward to lemons!
