Lemon tree's branches are snapping under weight of fruit
I'm a renter, and am not sure of the type of lemon tree I'm dealing with. The first year, the tree went from 6 ft tall to about 15 ft. It had almost no fruit that first year, just growth. Now it has been giving much more fruit last season and now this new batch has exploded. I have pruned a few lemons, and a handful have fallen off on their own... but the branches are still snapping down. They seem to still be alive, as the leaves are still green and the Fruit continues to grow, but the tree doesn't look very pretty.
I will attach a few pics...
Thanks in advance for any advise.
