Welcome to the forum. We are happy to have you as a member. There is a difference for fertilizing a plant that is growing in a container , and one growing in the ground. Plants growing in the ground do fairly well when using organic fertilizers. That is because the soil has plenty micro organism to break down organic fertilizers into usable elements that the roots can use and absorb. However. in container culture this is not so, because there is not enough organism to break your fertilizer elements into usable elements that the tree can absorb.. Your container trees will do much better using a commercial fertilizer. Your previous growing method is much of the reason that some of your seedlings died. I wish you and your tree well. For kumquats, varieties, only Nagami does not come true.
