Why are the leaves turning yellow on the Meyer improved lemon we planted on the south side of our home last spring 2015? We have had a lot of rain the last couple of months. I'm not sure what the fertilizer recommendation for these trees is, I prefer to use organic when possible.

Espoma makes a citrus fertilizer. As for growing them, I can't offer advice since I haven't quite developed the knack for my potted Meyer lemon.

Is it only the older leaves that are turning yellow? or are all the leaves turning yellow? Older leaves can turn yellow and fall off as they are no longer needed when there is plenty of new growth.

I have a couple of new lime trees in Arizona. Mine are having the older leaves turn yellow and drop. The new growth is fine, so I'm betting your lemon is ok.

You didn't mention where you live (state or country) but the yellow leaves on your Meyer Lemon (Citrus x limon 'Improved Meyer') could be from too much moisture from the excessive rain; especially if the soil is staying saturated and not draining well.

It's good you mentioned that, Lin. We had our watering set for too much, and we cut it down by more than half. I'll be interested to see if that stops the yellow leaves.

Thank you all for replying. I am thinking, like most of you: too much water. We live 30 min south of cows town Dallas Tx. That is why I planted them in the S side of our brick home. I will find the fertilizer that was mentioned and cross my fingers. Sincerely SJChoate.
