Graft line and trunk question
Hi, I have what seems to be a dwarf navel orange tree (not sure, makes good fruit). It has been in the ground for at least 4.5 years. The trunk has some bare wood on it that doesn't look so good and I was wondering what is was from and how I can help it.
Also, I was wondering where the graft line is on this tree so I can be sure I remove any suckers from the rootstock. Are there any suckers in the pics? All the leaves look similar, but I am new to this.
Lastly, am I ok to slightly trim back some gangly branches? I am not too concerned with appearance, but some branches are on the ground and others are just way outside the canopy.
