Steve, all are very nice!

Why do you use 'flying dragon stock'?

I am never sure of what stock my trees are on and I wonder if it makes a difference between survival, good growth, or death in my colder region?

The number 1 reason, the seeds were free and I had 3 grafting size FD seedling left. FD and Poncirus trifoliata are the best rootstocks for Meiwa and Fukushu. FD & PT Are great for cooler climate and also produce the best quality citrus. Seville sour is the top rootstock flavor in citrus and is the choice for those that do not have Trsiteza virus.

Most nurseries graft to the easiest rootstock whether they are compatible or not. they want their trees up and out fast.

This is a Fukushu kumquat grafted to each of 2 trunks onto PT which is grafted to sour orange Kumquats and Sour orange are incompatible. It is grown in the same bucket light my older Fukushu on flying dragon shown above post.

I've found Flying Dragon a slow grower. It seems to slow down growth of the scion a bit, compared to when it's grafted onto a PT hybrid like citrumelo or citrange. But scion growth is also influenced by the size of the rootstock.

I am hoping this slower growth will make for closer leaf nodes with more flowers per canopy volume.
