How to Grow Avocados in the Florida Panhandle: The Avocado Guild
Most people assume avocados stop somewhere south of Orlando. They don't. Cold-hardy avocados grow and fruit here on the Forgotten Coast if you pick the right variety and give the tree some help. At the nursery we do that with an avocado guild: one tree surrounded by a small community of plants that feed it, mulch it and protect it.
Quick answer: can you grow avocados in the Florida Panhandle? Yes. Choose a grafted, cold-hardy variety such as Fantastic, Winter Mexican or Mexicola Grande. Plant it in your warmest sunny spot, cover it on hard-freeze nights for its first few winters, and surround it with companion plants that build the soil.
Pick an avocado that can take our winters
Port St. Joe (ZIP 32456) sits in USDA Zones 9a and 9b. Winter lows usually bottom out between 20°F and 30°F. Hass, the grocery-store avocado, is damaged in that range. Mexican-type avocados handle it much better.
Fantastic Avocado: our top pick for the guild. Takes brief dips into the low 20s once established.
Winter Mexican Avocado: the other cold-hardy workhorse, with similar tolerance.
Mexicola Grande Avocado: a Mexican type with thin, dark skin and rich flavor.
Buy grafted. A grafted tree usually fruits in 2 to 3 years. A seedling can take 7 to 9. At maturity, a grafted tree can produce 50 to 200 pounds a year.
What is a plant guild?
A guild is a group of plants that support one central plant. Each member has a job: fixing nitrogen, pulling up minerals, covering bare soil, drawing pollinators or confusing pests. Together they cut down on fertilizer, watering and weeding.
The five companion plants
Pigeon pea (Cajanus cajan). Fixes nitrogen. Cut it back and drop the stems as mulch. Where: 3 plants on the north and east sides, 4 ft from the trunk.
Comfrey (Symphytum officinale). Deep roots pull up calcium, potassium and phosphorus. Chopped leaves become mineral-rich mulch. Where: 2 to 3 plants near the drip line on the south and west sides, at least 3 ft from the trunk.
Perennial peanut (Arachis glabrata). Living mulch. Covers the ground, fixes nitrogen, keeps soil cool and moist. Never needs mowing. Where: fills the whole 10-ft circle, plugs 6 in apart.
Lemongrass (Cymbopogon citratus). Aromatic border that can help confuse pests like aphids and whiteflies. Stalks go in the kitchen or on the mulch pile. Where: 3 to 4 clumps in a ring 8 to 10 ft from the trunk.
Passion fruit (Passiflora edulis). Adds a fruit layer that climbs instead of spreading. Its flowers draw pollinators. Where: 1 to 2 vines on a 6-ft trellis on the north side.
Step by step: planting your avocado guild
Week 1: prepare the bed. Mow or smother the grass in a 10-ft circle. Spread 4 to 6 inches of wood chip mulch.
Week 1: plant the avocado in the center. Dig wide and shallow and backfill with the native soil, no amendments. Avocados hate standing water, so if the spot puddles after summer storms, plant on a low mound.
Weeks 1 to 2: plant perennial peanut across the whole circle.
Week 2: plant 3 pigeon peas on the north and east sides. They'll reach 6 to 10 ft.
Week 2: plant 2 to 3 comfrey on the south and west sides.
Week 3: plant 3 to 4 lemongrass clumps around the outer edge.
Weeks 3 to 4: put up a 6-ft trellis on the north side and plant 1 to 2 passion fruit vines at its base.
Ongoing: water and watch. Water deeply twice a week for the first month. Chop and drop the pigeon pea and comfrey every few months.
Care through the year
Spring (Feb to Apr): Cut pigeon pea back to 12 inches. Chop comfrey and lay it around the tree. Top up the wood chips. When the avocado blooms, water a little less to encourage flowering.
Summer (May to Aug): Water deeply twice a week during dry spells. Harvest passion fruit as it ripens. Divide lemongrass to widen the border.
Fall (Sep to Nov): Water less as it cools. Add a final layer of compost. If lows below 28°F are forecast, cover young avocados with frost cloth.
Winter (Dec to Jan): Pigeon pea may die back; leave the roots in the ground to feed the soil. The avocado's growth slows, so hold fertilizer until spring.
Common questions
How long until a grafted avocado fruits?
Usually 2 to 3 years after planting.
Do I need two avocado trees?
No. One tree can fruit on its own. A second variety nearby can improve fruit set.
When should I plant?
Spring gives the tree the longest run before its first winter. If you plant in fall, plan to cover it on freezing nights for its first winter or two.
Do you ship avocado trees?
No. Pick up at the nursery or get local delivery (details below).
