(03/28) This Mikan orange tree is starting to produce buds. I bought this tree last year and estimate it is about three years old. It was grafted, which is why it is producing early. It is still small so only expect 10-15 Mikan oranges, but that's fine.
I had another Mikan tree that produced for a few years, but it got infected with bark beetles and died; however, before it died I was able to take a graft. The graft survived, but was growing quite slowly. I surrounded it with Peppermint plants and it suddenly started to grow. I suspect the mint keeps the soil moist allowing the root system to strengthen.
