David,
The thing you have to focus on is this is a MEYER lemon, which has special needs and "sensitivities". Lucky for you there are lots of people here with lots of experiences... good and bad, from which you can learn; the majority of them are container growers, so you have come to the right place. BTW, if it is possible to plant your tree inground, it is a LOT more forgiving than in container.

My motto: If life gives you lemons, pray they are Meyers.

Most likely, David. Re-pot right away and use a better draining potting medium. If you search for "gritty mix" or "511 mix" on this forum, you'll find recipes for making your own, well draining potting mix. Once you re-pot, you can try fertilizing in about 3 weeks with 1/2 strength Foliage Pro by Dyna Gro. That should help perk your plant up. Once you start seeing flush, you know you've turned the corner. Continue watering only when the tree needs it, and I would water every time with 1/2 strength fertilizer. If you've let the roots dry out, then only water with plain water, and you can then come back in a couple of days, and water with 1/2 strength fertilizer. Just remember, never apply fertilizer to bone dry roots.

What does "seeing flush" mean?

I have one message for re-pot right away and one for waiting, I'm uncertain what to do.

Flush = cycle of new growth.

My best advice... wait a bit until the flowers are finished; you could re-pot now; but it will only add more stress to the tree; and it REALLY does not need more stress now.

You could trust me on this; I have a fair amount of experience with Meyers.

Just remember, never apply fertilizer to bone dry roots.

Thanks Patty. I did not know that and that will help me in the future.

Hello Patty,

I am a "lurker" on this site and yours, MikeMeyer's and JohnMerr's advice is spot on. Thank you all so much for helping us out with our little trees. Sometimes, I even copy and paste your comments in a word doc!.

I think that the plant should be removed from the container with no drainage immediately. In lieu of going through the process of making your own potting medium, you could simply improve a good commercial mix by adding a substantial percentage of petlite. I belueve it to be imperative that the tree be transplanted now, no waiting.

You cannot water properly nor fertilize in this container. The roots do not have access to oxygen, without which they will die. Keeping this plant in the same container for another day is too long.

A good fertilization practice for container plants is to water thoroughly and allow the excess to drain away.....then water again lightly with soluble fertilizer added.
