Will you also post a picture of the under side of the leaves?

Thanks for your reply. I have added 3 pictures. 2 of them are of the underside of the leaves. The other picture is of a branch that has lost all of it's leaves except the last one.

Can you also post a close up of your new growth?

From the looks of the bottom pic, I can tell you that the mix you are using is not at all what I would use, even there...If you have gnats, then your mix is holding too much water. In fact, if the roots are suffocating form a mix that has collapsed all around the fine haired roots and holding salt deposits, then your tree is going to drop its leaves, the leaves are going to distort, and it will be susceptible to mites.....The tip of the branch on the left is dying back...Not a good sign.

Are you going to re-pot into a much better durable mix that allows the roots to breathe?

Thanks mikerno. This is my first meyer lemon and I am a beginner. Can you tell me what you mean by new growth?

I noticed that the soil has been retaining the water as my moisture meter is reading wet.

Yes I will re-pot, and I plan on using this soil mix:

Mikerno, do you think that when i purchase the new soil will arrive with gnats or other pest in them?

I don't understand the question Dave?

Do you mean that when you purchased the tree it might of had gnats?

Or do you mean that when you bought the soil if it had gnats?

Usually mixes sold in bags from stores or nurseries, unless you dug it from your yard or used decaying mulch, sell sterilized mixes..They usually treat them for pests before hand..The most probable way you got the gnats are from an environment that you are creating for gnats to thrive in, the same environment that trees decline in...

Dave, funny thing, I never saw that link till just now..It never showed up the last time I was here...Strange..

Yes, Limeinqueens is certainly right about meyers loosing their leaves in a move, but loosing branches is beyond that...I would fix the mix issue in a jiffy)

Thanks a lot for your advice. I am gonna research both the gritty mix and the 5-1-1. Since I need to re-pot because my soil is wrong, do you suggest that I shake or remove much of the old soil from the roots when I replant? When I was videos on re-potting, they seem to transfer much of the soil but I'm concerned that it will also carry the problem to the new pot.

I wasn't able to find the 5-1-1 online. Do you have a suggestion on where to get this?

You can get the 1.1. on line on E-bay..The 5.1.1 is easy to make..

Yes, I'd do a complete bare root washing all the old soil off the roots and start from scratch...)

Thanks for the details, Sorry but I am just learning. I found the reptibark online but this one seems to be more for reptiles. I couldn't find any reference to use this in potting soil. See pic. Is this what I should use?

Yep it's reptile bedding. That's the right product. Chips sold at garden centers are too big. This is perfect. If you search this forum you'll find lots of references to using it as the base for citrus soil. Figs like it too :)

Excellent. I will find this. Thanks

Thank you for all of your help. I re potted my lemon tree in the 5-1-1 mix last night. I watered it right afterward. This morning I checked the moisture and it read dry. Should it have been read moist?

Question: Should I add more water today to get it to moist?

With the 5-1-1 mix, how often do you water?

Did you pre-moisten, and mix all ingredients together well before potting?

The first time I made the 511 mix, I did not saturate the mix before hand and was forced to water twice a day for a few days to saturate the bark. I found and learned from others the bark with repel water otherwise.

Yes, I did pre-moisten and mix, but I didn't over flood it.

I would say that I have 4 gallons of mix and I added 1/2 gallon of water, then mixed it.

I have successfully re-potted my lemon using the 5-1-1 mix. It does drain much faster.

I watered the lemon about 3 days ago and it registered moist. Today (3 days later) it is registering dry so I watered it ago until it registered moist again.

Does this watering sound right? This would mean that I am watering about twice a week.
