Something's eating my citrus leaves...PLEASE HELP!!!

I have a Meyer's Lemon and a Blood orange in large pots. I just got them this past spring and don't want to lose them. Besides looking a sickly pale green, something is eating the leaves. What should I so? What's eating them how should I get them a pretty green color again. They will probably overwinter on my covered patio so I know I can't feed them anything with a high nitrogen number and I have no clue as what to use to kill whatever's eating the leaves. I'll try to get pictures tomorrow. I appreciate any help I can get.

Yellow leaves are usually due to overwatering or underwatering. Could also be lack of light, or a iron deficiency.

A photo would help identify the pest, I have a couple of grasshopper or grasshopper-type things that snuck into the greenhouse when I brought the plants in, and they have munched on some leaves. Check the plants over thoroughly and give them a good shake, and see if anything jumps or flies off.

Going to need pictures to figure it out.

Both of those will take some cold and need sunlight so if your not going under 32 I would leave them out in your sunniest spot. Both of those will take under freezing temps but why push your luck with young ones.

The leaves should be a dark green so yes you do have a problem and most likely a mineral problem if they have been getting full sun.

I vote for grasshoppers too. I think they just sit there and eat what they can reach which looks about like a half circle. I've never seen one in the act but that's all I see on my Meyers this year. They never eat the whole leaf and aren't a serious problem so far.

It's been raining for the past two days or I would have gotten pictures. Hopefully tomorrow!

Probably grasshopper since it is late in the year to be orange dogs or snails. Grasshoppers will even chew on the fruit peal.
I had an infestation of them chewing on my mustard and turnips a couple of weeks ago. Insects have trouble moving when the temp gets near 40 degrees so in the morning would be a good time to take a close look around the foliage.

Okay...here're the pictures. Another is following. It finally stopped raining and the patio is a mess. I'm in the process of making a green house on the patio for the winter so everything is messy right now. Can anyone tell what I should do about my citrus trees? I'm new at this and don't want to lose them.

Thanks for any help!

Here's a broader view.

Grasshopper or katydid.

Thanks Oldude. But this article talks about orchards. I only have a 3 trees in pots. How do I take care of them? I have some neem oil, will that do? I've moved the pots where they were from the back yard deck to the edge of my covered patio. The last time I had a Meyers Lemon, it did the same thing and died. I don't want it to happen again this time.

That photo before last looks just like mine. It never gets worse than that and I just ignore it. The temps we're expecting by the weekend should put a stop to them.

Thanks everyone...NOW...what do I do to get the color back. They're so pale. I know it shouldn't be anything with a high nitrogen content this time of year. Any recommendations?

I guess we got caught up in what was eating your trees and forgot to address the other issue. Do you plan to keep these trees in containers? If you are going to over winter and protect them from freezes then you can add fertilizer. The cautions of fall fertilizer and horticultural oil are directed toward in ground trees. Fertilizer promotes new growth and oil makes citrus more sensitive to cold but if you are going to protect these trees then go ahead and pamper them.
If you intend to keep them in containers permanently then we can help you with suggestions on fertilizer, micronutrients and potting material.
When you moved the plants did you place them in an area that has less sunlight? They really don’t respond well to quick changes in sunlight. It is also normal for citrus to shed a few leaves in the fall and this is especially true for lemons.

That about sums it up. Only thing I have to add is those pots look to small if you plan on keeping them in pots. I would re-pot about now. Those pots are only 1/2 full from the looks of it so you have very little soil in there.

I do plan on repotting them to larger pots. I don't know if I'll keep them in pots if I'm going to have this much trouble with them, I may plant them out but my DH is the problem...When he cuts grass, he doesn't like to cut around things but I may put my foot down this time. I have a raised bed I may be able to put them in..

When I moved them, I placed them on the edge of a covered patio for several days. They are now under the covered patio which I have made a greenhouse out of for the winter. It's snowing here so it fairly cold for us here in zone 8b. This is rare for us especially since it has snowed here two years in a row. Should I leave them under the patio or should I bring them out when the weather gets better?

Citrus always needs sun. Under our normal winter temps, they'd be fine in an area sheltered from north winds. Those small ones might best be covered with an old blanket if the temps get much lower than 30 or if temps stay low for many hours.

Pine straw or bark makes excellent mulch to keep the lawn mowers and weed wackers away from fruit trees. That should keep hubby happy and the trees do much better through dry periods. They do not need a raised bed unless your other locations are water logged.

The forecast has been lowered from 32 to 29 here just in the past couple hours and it's drizzling. The weather is getting so crazy that I guess we better try to prepare for anything.
