Z You don't describe the fate of your previous Meyer lemons, so forgive me if my advice is too basic. First, I don't think you've allowed enough time to reach any conclusions about the grafted tree other than when purchased it was in its dormant phase, and two months ago it emerged out of that phase. If all goes well, you'll probably see another flush of growth later this spring. The cutting-derived tree sounds like it may have experienced some relocation shock or some kind of cultivation-related problem (overly dry air, too much fertilizer, a poor root-to-leaf ratio, dry pockets in the soil, etc.). However, that said, my Meyer Lemon, which may be a grafted tree, though I'm not at all certain, which I've had for 25 years, drops many of its older leaves every fall like clockwork as soon as I bring it inside for the winter (my other trees drop their older leaves too, but the Meyer is more extreme in its behavior). The Meyer lemon also always looks more bedraggled than the other citrus trees: it has a sparser canopy of leaves, and its coarse growth pattern is unsightly compared to the relatively petite branching patterns of my Key Lime, Calamondin, and seed grown orange. The Meyer Lemon is closest to my Ponderosa lemon in its appearance, which I suppose makes sense! You may also want to cut back on the fertilization schedule when the trees are not actively growing. I've grown containerized citrus for over 30 years, and I don't usually fertilize them when they are dormant. When they are flowering and actively growing, I fertilize every two or three weeks at most, and I cut the recommended amount of fertilizer in half (I've used Peters' blend for acid-loving plants, though it is now marketed under the Jack's Classic label). If a tree is struggling, giving it a sizable dose of nitrogen every other watering is probably causing it more stress than less. This is possibly even more so in the case of a rooted cutting, which may not have a root system that is completely up to the task of supporting new growth and flowers.

I would give it a shot... But what I do is cut all the leaves in half before trying to root them. I rub the ends of mine in rooting powder and stick them in a place I know where they will be warm, hydrated, humid, and lots of light....100% success rate will happen if you do your proceedure correctly.... Good luck and let us now if you root any...I love rooting cuttings since they give fruit and flower within days of rooting.... Mike

Just wanted to give everyone an update. I am very happy with how my Meyer Lemon cutting has grown since the pics (repot) above in March. I really do like these pots a lot. I have been watering every 3 days, I give the cutting 1 tbsp foliage pro / gal once a week, and just try to give it as much sun as possible. Seems to be doing very well.

Per Johns advice YEARS AGO, I planted my cutting and air layers deeper then normal, and roots have grown all the way up the stalk to the base of the soil. I did use a 5-2-1 mix and let it dry in between waterings to a lightly moist state.
