Over the winter, all of the trees in my greenhouse flushed massively. Most also bloomed heavily, except the kumquats. These put out little to no blooms and didn't set any fruit. They easily doubled their canopy size, though. This spring I also purchased some new 3yr kumquat trees that arrived with little to no fruit set. Can I expect another round of blooming this spring/summer or do I likely need to wait until next year?
The three kumquats I had since last year all had fruit (10-30 each) that I ate over the winter so they are definitely large enough. All old & new trees are 3-4yr grafted trees from FourWinds. Varieties are Meiwa, Marumi, Changshou/Fukushu, and Nordman Seedless. All of my other citrus trees set plenty of fruit at the same time in the same environment
