I bought a pear tree that is supposed to have 5 different kinds of pears. It has been out three years and is doing good except it has never bloomed. It also has long thorns on it. It is a dwarf tree but is probably 7-8 ft tall. Why no blooms?
Fruit trees will forgo flowering while it gets a root system established. Once it has extra energy to spare, it will start flowering. To help it get established quicker. pound some holes a foot or so deep out around the tree away from the trunk about as far as the outermost branch tips and fill the holes 3/4 full with Espoma Bio-tone food. If the tree is getting less than 8 hours of direct sun per day, it will struggle to thrive, flower and produce fruit. The more full sun, the better.
