Sometimes if a plant is stressed and thinks it is going to die soon, it will fruit like crazy. It's hard to know if that's the case when plants do that, or if they are just super healthy, the exact opposite. However, if you are concerned about the plant using too much energy for the fruits, you could always take them off, or take all but one off? I did that yesterday with my little olive tree, it had hundreds of "olives" (about a millimeter or two), I also found out yesterday that it had thrips. I sprayed for that, so hopefully it will be fine but it made me wonder if that is why it fruited so crazily. In past years there was never any fruit. Anyway, we will see if it survives and what happens next spring/summer too.
