I am looking for some fertilizer to feed the trees in fall to promote root growth. What is a good product to use for low nitrogen fertilizers that is readily available?
Low nitrogen fertlizer is unnecessary.

Don't sweat the low N stuff...
Our work has shown that fertilizer composition has no effect on cold
hardiness. Fertilization may prolong the growing season, hence may increase
early frost damage.
The safest fertilizer for end-of-season supplementation is a complete (NPK)
fertilizer.
All trees germinate, grow, bloom, then grow again, bloom again and then again for years with the same non optimal mineral nutrition.
Why should it be different in a pot ?
