Trees, Shrubs and Conifers: why does flowering quince only bloom at the bottom, 1 by smitful

I have several Flowering Quince that I grow as bonsai Trees. They are kept outside year round, and the pots are covered with mulch during the winter to protect the roots from freezing. While the flowers form on wood one year old or older, some blooms on this “Texas Scarlet Clump Style bonsai” are at the ends of the branches because the new growth has been trimmed off. This photo was taken in February, and was a welcomed sign that spring was around the corner.
