Oak with holes in leaves
Comments (9)Here is a link to a better photo: http://s306.photobucket.com/albums/nn245/ixodid/examples/?action=view&current=oakleaves.jpg Just as a follow-up, here is what I found out: It is the damage done by the oak leaf shothole leafminer. This small fly makes a series of feeding punctures in the leaves while they are very small, then the female will lay an egg and the larva will make a little blotch mine at the tip. The mine damage often drops off as the leaf expands and the holes get larger. No control is recommended as the health of the oak trees does not seem to be affected. I would suspect that one of the neonicotinoids (Merit, Arena, or Safari) would eliminate this little fly if applied (by soil drench or injection) before bud break of the oaks.

Comments (27)Lol!!! Toni, I meant all the leaves are falling off!! I didn't have this problem last year. The only difference is that I have kept the room a little cooler especially at night this winter than last, but just as much light and sun. Of course when my plant room was warmer last year, I had more bugs...Go figure. Now I have to choose. Could it be that it should be warmer in this room so the soil is warm enough to take up nitrogyn and other nutrients with all the lights on? Is yellow veining followed by leaf drop a symptom of not enough light or warmth? That lemon meyer tree has even lost a few branches now. I stuck it right under a grow light and put the thermostat higher yesterday and now lets see what happens. I am going to keep the nights higher than 65 at night, and pay a higher heating bill for that poor plant. I hope it makes it. It is a toss up between a cooler room and lack of pests along with poor growth and higher humidity, or more warmer room temps, more possible pests and more work at humidity and keeping pests away, but better growth... Boy do I wish I could leave them out all year instead this. I can't wait to stick them outside already, especially this problamic tree, my lemon meyer.....:-(...See MoreNew Trees dropping leaves
Comments (3)Rouxtroux, It's quite normal for trees of the same species planted at same time to grow at different rates, color at different times in fall, leaf out in spring later or earlier than another. Plus newly planted trees will adapt to their new soil in slightly different ways so I wouldn't worry about the variations. I'm not familiar with the Blanchard Magnolia...you might call your nursery. Newly planted trees and shrubs need a good watering once a week for the first year or two. If it doesn't rain, water well. I'm assuming you have them planted in good well drained soil. They should be fine. This forum isn't very busy...you might want to post on the Trees forum which has some awesome tree experts which give friendly help. Good luck with your new trees. josh Here is a link that might be useful: Tree Forum...See MoreMeyer lemon problems:pale leaves, dropping leaves
Comments (95)Amanda, it looks to me like that tree is a gonner. You’ve put too much stress on an already stressed, under watered, under fed tree. I’m afraid it will see its demise indoors. If it were me, I would take the winter and do some research on root stocks and how they effect the growth habits of the citrus tree you want to grow. Then I’d go to my local nursery like Armstrong’s or wherever you normally go in LA and find a new tree that is grafted to said rootstock that you researched in January and plant said tree in Late January early February into the ground. Late winter early spring is the perfect time of year to plant citrus trees In ground. Then I’d water it consistently and deeply the first year and fertilize it lightly monthly. That’s it. The more care and worry you give to your trees the worse off they end up being from over care. You see, in ground trees are very different than potted trees. They need a lot LESS care, you have to let them do what they’re going to do and address issues only if they arise. Not every tree is going to look perfect or have deep green leaves or bear fruit the first 1-2 years, it takes patience. Rest assured though, you live in LA, it’s basically the perfect climate to grow citrus in so if you have patience and keep an eye on your tree it will reward you with a bounty eventually.
