We bought two kumquat trees on impulse on my husband’s birthday in April. Somehow I misplaced the tag that came with them and only noted at the time that they were kumquat in the genus Fortunella.

Each is only 2 ft tall. I planted them near the garden hose so I can water them frequently until they are more established. There is mulch around each to keep the soil moist and to reduce weeds in the area. They are on the east side of the house in full sun from 7:00 AM – 4: PM when the shadow of the house finally provides shade. I realized a few days ago that one of them had a flower, and by today there were a several flowers on the same tree. The other one has no flowers yet. The flowers are tiny, about a half an inch in diameter. Although the flowers are tiny, there is so much in my yard that is new and just getting established, that it is a relief and a joy to see the flowers.

This IFAS summary includes a description of kumquat fruit of the 4 varieties grown in Florida. Once I have fruit on the trees, I should be able to determine what variety they are based on the fruit.

Apparently kumquat have a number of disease possibilities, so I will have to watch for potential problems. This crop/pest management information should help to diagnose and to determine treatment if they develop any problems.

Added Note (5/24/10): I found the tag and notes on the kumquat trees. They are the Fortunella margarita hybrid known as the Nagami Centennial variety. They are cold hardy and will have egg-shaped bright-orange fruits. See University of California Riverside website for additional photos and details.
