They say that kumquat trees can't be grown from seed because they have week roots. I have 2 seed grown kumquat trees, 1 meiwa &1 nagami. The only thin week about the roots is they grow very little and are to small for the tree above them and the tree doer not grow but a 1/2 inch at a time. Is this what we look for in bonsai characteristics.

Nagami kumquat with short gangly roots

Roots will take year to reach their container wall. Should I just trim off the tip of the branches.

Has any one used a kumquat tree for an on own roots kumquat bonsai.

Thanks
