Meyer Lemon/Mexican Lime Espalier
I have 2 large brick areas that run along the south side of my house where I have all the raised bed gardens. I have been trying to figure out what edible I could espalier in these spots, when it occurred to me that I would prefer to not bring the lemon and lime trees inside with the evil cat all winter. We're here all the time and could cover them in frosts, but the area is completely protected from north winds, and there's another house 10 feet away... I think it's an ideal area to attempt something like this.
Have any of you seen an espalier done with citrus? I've never done one with anything, and I'm not sure where to start. Should I let it adjust to life in the ground first before pruning it back, or do you think it's tough enough to take it all at once?
