Fruit contain many seeds when grown in a mixed block. It produces poorly in solid blocks because it is self-incompatible. It produces a medium-sized tangerine-like fruit that is not easy to peel. Orlando Tangelo is a Dancy tangerine and Duncan grapefruit cross. They may be harvested just before Christmas. Navel trees seem to be fairly cold hardy and should be under consideration for North Florida. There have been no reported problems with Alternaria or citrus scab. Minneola is very susceptible to Alternaria fungus, and a rigorous spray program is required for commercial production. It appears to be less cold hardy than LB8-9 (Sugar Belle ®) and has a later maturation (late December to January). Minneola Honeybell: Minneola is an older cultivar that produces an attractive, medium-large, bell-shaped fruit. Early Pride should be supplied with microsprinkler irrigation for freeze protection. It is not cold hardy, and should only be considered for the best sites that are sheltered from north winds. Early Pride appears to be somewhat resistant to Alternaria and citrus scab. It produces a high-quality, medium-sized fruit with good flavor that is easy to peel. The fruit-maturing period is September and October, a time when little other fresh-market citrus is available in North Florida. Other important traits include cold hardiness and seedless varieties that are uniformly small to moderate in size, attractive, sweet, and easy to peel.Įarly Pride is a low-seeded Fallglo-like fruit. Researchers are particularly interested in early-maturing mandarins that would be available on the market from November to January. The citrus varieties that mature before Christmas have the best chance for success in North Florida since citrus fruit will freeze in response to prolonged temperatures of 25 to 27 F. To reduce wind speed during freeze events, it is highly advisable to select a location that is protected by woodlands or other barriers on the north quadrant of the grove. Nevertheless, low-lying areas that can serve as frost pockets should be avoided, if possible. In North Florida, microsprinkler irrigation for cold protection is imperative, especially for the non-satsuma varieties. ![]() Satsuma did not sustain any significant cold injury. The last 10 years have experienced temperatures as low as 15 F, and Navel, Minneola Honeybell and Valencia have not experienced damage other than tip burn. The coldest temperatures recorded in Quincy for the winters of 2015–2016, 2016–20–2108 were 26, 26 and 20 F, respectively. To avoid peel tearing, satsumas must be clipped to be harvested and should be handled with care because they are more prone to bruising than most other types of citrus.Ĭurrently, there is an urgent need to diversify fresh-market citrus in North Florida to include varieties that mature from September through December.Īt the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center in Quincy, many varieties and numbered selections have been under evaluation for up to 13 years. They mature and are harvested during a four-week period centered in mid-November. When properly cold acclimated, satsumas are cold hardy down to about 12 to 14 F. In 2017, the acreage of citrus by county in North Florida was as follows: Gadsden, 120 Jackson, 31 Jefferson, 30 Taylor, 34 Madison, 30 and Suwannee, 20. Satsumas are the most cold-hardy commercial citrus and account for a great majority of the new commercial citrus acreage in North Florida. The relatively mild winter temperatures during the last three decades and the development of microsprinkler irrigation in the early 1990s to reduce the effects of freeze (Figure 2) have led to a resurgence of interest in cold-hardy citrus in North Florida. A young citrus reset covered in ice from microsprinkler irrigation helps reduce cold injury to the tree.
