Hello

These are my bonsai trees, a dawn redwood (metasoquia) Azalea (Rhododendron), loropetalum (chinese fringe flower), chinese maple (acer) and a cherry blossom (prunus)

I'd like to get an advice on when to repot the dawn redwood forest because a very small amount of roots are coming out of the pot (barely visible in the pic) right now is the 4th of May so it would be like late spring, I read it's supposed to be done early spring but the roots coming out of the pot are my main concern

If you can also drop some advice on how to take care of the, I have some books which I am reading but never bad to ask for extra advice.

Thanks and have a great day
