Pomegranate — Sebastian, Florida

Pomegranates grow in Sebastian as a dooryard shrub or small tree, since UF/IFAS places the plant in Florida hardiness zones 7 to 11, but summer rain on the Treasure Coast makes clean, full-size fruit the hard part.

UF/IFAS Gardening Solutions describes pomegranate as an attractive deciduous shrub that grows 6 to 12 feet tall, or as a tree that may reach 20 feet when trained to one trunk. It is self-pollinating, so a single plant in a Sebastian Highlands backyard can set fruit, and it fruits better in full sun than in shade. Pomegranate plants 80 to 100 years old have been found in the Panhandle, and Gardening Solutions notes the trees have been grown as dooryard plants in Florida for decades.

Survival and harvest are different questions. UF/IFAS MG056 states that Florida's wet season, together with hot weather, reduces fruit quality through disease pressure, especially for late-season varieties such as Wonderful, and that the economic potential for commercial pomegranates in Florida is currently unknown. Sebastian sits in that same humid summer pattern, which is why cultivar choice decides most of the result.

On cold, the other weather question for Sebastian growers, MG056 calls the pomegranate more cold-hardy than citrus, notes that cultivars vary in frost tolerance and that temperatures down to 12°F may in some cases severely injure dormant trees, and shows late freeze damage at 28°F to a non-dormant tree in Cross City, far to the north, in March 2018.

Sebastian's summer rains carry the fungal spores that rot pomegranate fruit, and UF/IFAS reports that anthracnose alone can destroy up to 100% of a crop before it matures in Florida.

For a Sebastian pomegranate, UF/IFAS EP643 explains that Colletotrichum spores are waterborne and typically start infections at the beginning of the rainy season, which runs from late May to June through September in Florida. The publication describes sunken lesions that can rot the fruit inside and out.

A second pathogen adds leaf damage to Sebastian plantings. A 2018 review in the Proceedings of the Florida State Horticultural Society by UF/IFAS Gulf Coast scientists reports that fungal diseases caused by Cercospora punicae and Colletotrichum appear to be the most problematic in the southeastern United States, and that rain splashes help disperse spores. Gardening Solutions names leaf blotch and fruit spot as the diseases often seen on Florida trees, with infected leaves falling early.

Timing is the practical lever in Sebastian. MG056 says Florida research needs to focus on earlier varieties that can be harvested in July and August to reduce disease pressure, and it notes that the late-ripening Wonderful might not be the suitable cultivar for Florida. MG056 names anthracnose the most destructive pomegranate disease observed in Florida and says at least three sprays per year of neutral copper fungicide can reduce its impact.

In UF/IFAS trials, Azadi held up best against anthracnose fruit rot, followed by Arakta, Christina, Eversweet, Fleishman and Jimmy Roppe, the best documented choices for a Sebastian yard.

For Sebastian buyers, EP643 is the key reference: it reports a test of 35 cultivars in 2021 and 27 in 2022 at the UF/IFAS Gulf Coast Research and Education Center, where no fungicides were applied. Azadi was the only cultivar rated highly resistant. Christina and Jimmy Roppe come from Florida and Georgia, and Eversweet and Fleishman from California. At the other end, Kazake, Eve and Al-Sirin-Nar had the most fruit rot at the end of the 2022 evaluation. The field trial ran under natural disease pressure in central Florida.

Another UF/IFAS list reads differently. Gardening Solutions names Girkanets, Kazake, Wonderful, Al-sirin-nar and Medovyi Vahsha as varieties that have performed well in Florida and calls Christine and Salavatski popular home-garden cultivars. The EP643 trial measured anthracnose only, so a Sebastian grower comparing nursery tags against both lists will find Kazake and Al-Sirin-Nar rated well for general performance and poorly for fruit rot.

A Sebastian pomegranate goes in during February or March, in full sun, in well-drained soil with a pH between 5.5 and 7.0, and needs water every 7 to 10 days in dry spells.

Soil is the first check. MG056 says pomegranates are adapted to soils from pure sand to heavy clay, but yields are usually low on sands and growth on alkaline soils is poor, with optimum growth at pH 5.5 to 7.0. The Indian River County Master Gardener Program lists soil pH tests among its volunteer services, and its Sebastian clinic meets at the North IRC Library, 1001 Sebastian Blvd. (CR 512), on Wednesdays from 10 a.m. to noon.

Water needs match citrus. MG056 puts the requirement at about 50 to 60 inches per year, with irrigation every 7 to 10 days when there is no significant rain, and warns that sudden changes in watering lead to fruit splitting a few weeks before harvest. The plant is tolerant of some flooding, an advantage on low Sebastian lots that hold water after a summer storm.

Spacing and shape on a Sebastian lot follow the same publication. MG056 recommends planting in early spring, February to March, spacing dooryard trees like orchard trees at 10 to 16 feet apart, and 6 to 9 feet apart for a hedge. Trees are easily propagated in winter from hardwood cuttings, which in Florida should be taken in January or February, and seed-propagated plants do not come true to type. MG056 adds that light, annual pruning of established trees encourages good quality fruit, and that sprouts and suckers should be removed as they appear.

The City of Sebastian fertilizer ordinance exempts trees grown for their edible fruit, so a fruiting pomegranate in Sebastian is outside the June 1 to September 30 blackout that covers lawns and ornamental beds.

City Code Sec. 50-5 defines its prohibited application period as June 1 through September 30, plus any flood, tropical storm or hurricane watch or warning covering part of Sebastian. Its exemption list ends with vegetable gardens and trees grown for their edible fruit. A dwarf pomegranate planted only for its flowers in a Sebastian foundation bed is a landscape plant, and the exemption does not name ornamental plantings.

More fertilizer is not better for young Sebastian plants. MG056 reports that severe fruit drop during the juvenile period of 3 to 5 years is not uncommon and is aggravated by over-fertilization and excess irrigation. Insects are a smaller issue: MG056 says scale and mites occasionally attack the plant but do little damage, sulfur dust in early June controls mites, and a 3% oil spray in winter, when the leaves are off, controls scale. Tree borers can infest and kill trees.

Named, cutting-grown cultivars such as Christina, Eversweet or Fleishman are the plants to look for, and the Wednesday Master Gardener clinic in Sebastian is where volunteers diagnose plant problems on an existing plant.

The Master Gardener program's Extension office at 7961 58th Avenue in Vero Beach also runs a plant clinic Monday through Friday, and the program phone is (772) 226-4324. The program lists diagnosing plant problems and performing soil pH tests among its volunteer services, so a spotted leaf and a damaged fruit from a Sebastian plant are worth bringing along.
