Papayas — Sebastian, Florida

In Sebastian, as everywhere in Florida, only female and bisexual papaya plants bear good fruit, so growers start two or three plants and keep the productive ones.

Papaya seedlings in a Sebastian yard come in three sexes. UF/IFAS EDIS MG054 describes male plants with small tubular flowers on long stalks, female plants with large flowers and a large ovary along the trunk, and bisexual plants with perfect flowers, and says fruit is normally produced only from female and bisexual plants (UF/IFAS EDIS). Female plants bear medium to large round fruit with a large seed cavity, bisexual plants bear elongated fruit with a smaller cavity, and male plants give at most a few poor, pear-shaped fruit.

Nursery plants improve the odds. UF/IFAS Gardening Solutions says most papaya plants sold in nurseries are female or bisexual, that female plants need a male nearby for pollination, and that bisexual plants can self-pollinate (UF/IFAS Gardening Solutions). For a Sebastian Highlands lot with room for only one papaya, a bisexual plant is the practical choice.

Variety names are few. MG054 lists 'Red Lady', 'Maradol', 'Tainung No. 1' and various Solo types as important papaya varieties in the U.S., and notes that seed is not commonly sold in small amounts. Gardening Solutions adds that Solo types tend to be more susceptible to papaya ringspot virus and that dwarf-like varieties, easier to cover or move before a Treasure Coast cold night, are hard to find.

Papaya in Sebastian lives at the cool edge of its range, where any winter dip below 59 degrees F interrupts flowering, a frost can kill it, and summer storm winds can snap a plant heavy with fruit.

The zone map frames it. Gardening Solutions places papaya in USDA Hardiness Zones 9B through 11 and says Florida papayas are short lived, rarely reaching ten years old (UF/IFAS Gardening Solutions). MG054 gives the working range: plants grow and fruit best at 70 to 90 degrees F, root growth slows when soil temperatures drop below 60 degrees F, and temperatures below 59 degrees F may inhibit flowering or produce misshapen fruit (UF/IFAS EDIS). In practice, a Sebastian papaya sets most of its crop in the warm months.

Wind is the other limit. MG054 says papaya plants are susceptible to wind damage, will not establish well in continuously windy areas, and are very susceptible to toppling when carrying a large amount of developing fruit. A spot on the lee side of a house in the Sebastian Highlands is therefore a better home than an open lot facing the Indian River Lagoon off Indian River Drive.

Salt and wet ground hurt too. Gardening Solutions lists salt spray among the conditions that reduce a papaya harvest and says papaya will not thrive in boggy soils, calling for a mound of native soil where flooding is common. That rules out the lowest corners of many Indian River County lots and the most exposed spots east of US 1 near the water.

A Sebastian papaya is started from seed or a potted plant, set out in spring at 6 to 12 inches tall in full sun, and planted in a group of two or three about 7 to 12 feet apart.

Seed is easy to save. MG054 describes pressing seeds from a ripe fruit against a colander to break the sac that inhibits germination, rinsing and drying them, then sowing 2 to 4 seeds per 1-gallon container (UF/IFAS EDIS). Germination takes 2 to 3 weeks, the strongest seedling is kept, and plants go into the ground once 6 to 12 inches tall. Gardening Solutions suggests starting plants in containers during winter and moving them out in spring (UF/IFAS Gardening Solutions), which keeps a young Sebastian plant out of winter cold.

Spacing protects the harvest. MG054 says papaya plants belong in full sun at least 7 to 10 ft from other plants, buildings and power lines, and that planting 2 to 3 papayas 7 to 12 ft apart helps ensure at least one is fruitful. Papayas are not pruned, because the main growing point is at the top. Papaya plants and other fruit for Sebastian yards appear among the fruit trees on Digital Towns Market.

Papaya ringspot virus is the disease most likely to end a Sebastian papaya, while the papaya fruit fly ruins individual fruit and nematodes weaken the roots.

The virus sets the replanting clock for Sebastian growers. MG054 calls papaya ringspot virus the most important disease of papaya in Florida, with early yellow mottling and vein clearing on leaves, distorted leaf lobes, dark green streaks on stems, and dark circles or C-shaped markings on the fruit (UF/IFAS EDIS). It advises removing all plants with symptoms and, because of the virus, replanting papayas every 18 to 24 months. Seed from small, pear-shaped Solo-type fruit tends to be more susceptible than seed from larger oval market fruit.

The fruit fly looks like a wasp. MG054 says the papaya fruit fly lays eggs through the peel into the fruit cavity, where larvae feed and ruin the fruit, and that the easiest control is a paper bag or paint strainer cloth over each small fruit until harvest, a cheap fix for any Sebastian backyard plant.

Smaller pests add up. Papaya webworm, papaya whitefly and two-spotted mites attack fruit and leaves, and root-knot and reniform nematodes make plants more likely to topple, per MG054. Gardening Solutions notes nematodes are particularly difficult to manage and suggests a container where they are known (UF/IFAS Gardening Solutions). Master Gardener volunteers with UF/IFAS Extension Indian River County diagnose plant problems, including at a Wednesday clinic in Sebastian at the north county library on Sebastian Boulevard (UF/IFAS Extension).

Sebastian papayas take small, frequent feedings, daily or every-other-day water in hot weather on sandy soil, and harvest once a tenth to a third of the peel turns yellow.

The feeding schedule is tight. MG054 says young plants should be fertilized every 14 days with a quarter pound of complete fertilizer, and plants about 7 to 8 months old with 1 to 2 lb every other month (UF/IFAS EDIS). On well drained sandy soils, the kind found on many Sebastian lots, it calls for watering every other day or every day during hot, dry weather, and less often in late fall and winter.

County and city rules shape summer feeding. Indian River County's ordinance bars fertilizer from June 1 to September 30 and within ten feet of any water body or seawall, exempting vegetable gardens and trees grown for their edible fruit, and it applies in unincorporated areas (Indian River County). Inside Sebastian city limits, the City Fertilizer Ordinance linked from the city's Florida Landscaping page governs (City of Sebastian).

Harvest comes with the first color. MG054 says fruit may be picked when yellow covers one tenth to one third of the peel, though more color on the tree raises sugar content, and that ripe fruit keeps 4 to 7 days. Green fruit can be harvested and used as a vegetable, so a Sebastian plant carrying more fruit than a household can eat still has a use for it.
