Of all the citrus that ripen about now in winter and early spring, oranges, lemons, limes, grapefruits and mandarin oranges (or mandarins or tangerines) are the most familiar. (A tangerine is merely a mandarin that was developed in the Americas.) Kumquats, blood oranges, sour oranges, citrons and many of the odd citrus hybrids that are less common are becoming more popular as their fruit becomes more available in markets, and their trees become available in nurseries. Except for the very popular ‘Meyer’ lemon, which is actually a hybrid of an orange and a lemon, the most popular citrus hybrid is likely the ‘Minneola’ tangelo, which is a hybrid of a grapefruit and a mandarin orange. Other tangelos remain somewhat rare.
Like all citrus, ‘Minneola’ tangelo has appealingly glossy evergreen foliage and fragrant flowers. They can be grown in containers if their roots are dug, pruned and planted again every five years or so. They like regular watering, good drainage and mulch. Aphids, mites or scale can become problematic. Suckers from below the graft should be rubbed off as they appear. (The graft union can be identified by the change in bark texture and color on the main trunk just a few inches above the roots.)
‘Minneola’ tangelo trees get a bit larger than mandarin orange trees, but not as large or quite as full as grapefruit trees. The bright reddish orange fruit has all the flavor of mandarin oranges, and is just as easy to peel, but unlike the majority of mandarin oranges, has few seeds, and can be left on the tree through spring. The fruit is a bit smaller than that of ‘Valencia’ orange, and has a distended bump where the stem is attached. Flavor develops best in warmer parts of the garden, particularly after warm summers.
