My dad has this terrible tree setup, I think it's 2 different trees, a lemon tree covered by a taller bushy tree. I don't have full control here, I can't cut these down/tear them out, but I am charged with the task of picking the lemons. Every lemon, before it freezes tonight. The lower, deeper lemons were so far into this big overgrown tree with giant thorns, and it's so thick and low to the ground I'd have to crawl on my belly in the mud to get to half the lemons in this horrible setup, so I started cutting some of the lower branches away from the ground. I realize this isn't the season to be doing this but I'm told I have to handle it now some way or the other.
Obviously I want to be able to get to the lemons, cut the branches off of that stairway, and make the result look somewhat good. Could someone identify these trees so I can lookup what they're supposed to look like after pruning, and any other info that can help me create a decent result out of this scenario.
Edit: I'm told they're grafted. I have a vague understanding about grafting. Looks like the bush died down, came back and the plant went up high but the lemon part only grew down low. I don't know if there is a great solution here, in this case. If the answer is "Meh, it's hopeless," then just say that.
