I believe you are safe. If Citrange leaves are trifoliate then you are safe and I would do nothing as I have on all my trees in the past. They all have done very wll except my seed grown kumquats. yours is grafted. Steve

If you opened this thread, I will add the evolution of my fukushu kumquat grafted on rio red grefruit seedling in 2014. It is now in 15-20L airpot, with generic potting soil amended with perlite, keramzit and bark. It is in the new location for 2 months, and this week flowered nicely. New little branches grew from the vertical stem (the last watersprout), growth that stopped now (right after full moon).

No, just been change, you still holds the other one. Vlad might get jealous, but I know you get his approval. He is a good guy.

Nice going. The Fukushu kumquat grows very well on its own roots. Plant some seeds an graft mature wood to your seedling. Steve
