Espalier apple tree...what to do??
I'm new so I hope this is the correct forum.
I really wanted an apple tree for the backyard but my only option was an espalier due to space restrictions. The only espalier I could find was one grafted with six varieties...
It is still rather short (about 5ft) and I have enough space to let it grow larger. If I want more vertical growth, will I have to source and find material to graft on?
Also, is there a way to determine if the main trunk is rootstock, or a named variety?
