Tree · Persea americana

The grocery pit on toothpicks is a fun kid project but rarely fruits — for real avocados buy a grafted 'Mexicola' and grow it in a pot you drag inside. Cold-hardy Mexican types push the frontier to zone 8.

Growing

Light, water, soil, propagation and the season’s jobs.

How to grow avocado: light, water & soil

LightFull Sun
WaterModerate — deep soak then dry; root rot is the killer
SoilLoose, fast-draining, slightly acid · pH 6.0 - 6.5
FertilizerCitrus/avocado feed 3-4x in season; zinc + iron matter
PruningAfter harvest — Tip-prune potted trees to stay bushy; stake young trunks.
Spacing20+ ft; container 5-8 ft

What avocado is grown for

✓ Commonly eatenSafe for people; leaves/bark/pit are dangerous to BIRDS, horses and livestock (persin). For dogs and cats the real risks are GI upset, pancreatitis from the fat, and choking on the pit — not persin poisoning

Harvesting & storing avocado

Fruit holds ON the tree for months — 'store on the tree', pick as needed; softens only after picking.

Edibility, identification, and traditional-use notes here are general reference — not medical or veterinary advice, and not a claim that any plant treats or prevents anything. Medicinal ratings record how strongly a plant features in herbal tradition, nothing more. Never eat or dose a plant you have not positively identified. More on how to use this library.

Best avocado varieties & cultivars

9 on file

Named varieties of avocado differ in winter-chill needs, ripening time, hardiness, and whether they set fruit on their own — pick one that fits your climate.

Hass · Hass Avocado

Partly self-fertile
RipensSpring through summer (Apr-Sep in CA)Zones9-11Diseasesusceptible to Phytophthora root rotSizestandard 15-30 ft (prune to keep smaller)
Pollinationflower type A (best yield with a type B nearby)

rich, nutty, high-oil; skin turns black when ripe — The industry standard for flavor, but tender (damaged below ~30F), so it needs a nearly frost-free spot.

Fuerte

Partly self-fertile
RipensNov-Apr (winter-spring)Zones9-11Diseasesusceptible to Phytophthora root rotSizestandard, large spreading 20-30 ft
Pollinationflower type B (classic pollinizer for Hass)

smooth, buttery, mild; green pear-shaped fruit — A hardier (to ~28F) green-skin classic and the traditional type-B partner planted alongside Hass.

Bacon

Partly self-fertile
RipensNov-Mar (fall-winter)Zones8-11Diseasesusceptible to Phytophthora root rotSizestandard, upright 15-25 ft
Pollinationflower type B (pairs with type A like Hass)

light, watery, mild flavor; thin green skin — One of the more cold-tolerant grafted varieties (to ~25-28F), making it a good pollinizer and backyard tree for cooler-winter areas.

Zutano

Partly self-fertile
RipensOct-Jan (fall-early winter)Zones8-11Diseasesusceptible to Phytophthora root rotSizestandard, upright 15-25 ft
Pollinationflower type B (widely used to pollinize Hass)

light, watery, low-oil; thin green skin — Grown mostly as a reliable, cold-tolerant (to ~24-28F) type-B pollinizer rather than for its fairly bland fruit.

Mexicola Grande · Mexicola

Partly self-fertile
RipensAug-Oct (late summer-fall)Zones8-11Diseasesusceptible to Phytophthora root rotSizestandard, vigorous 20-30 ft
Pollinationflower type A (fruits well alone; add a type B to boost set)

rich, nutty, anise-tinged; small fruit with thin black skin and large seed — A pure-Mexican variety hardy to about 18-20F, one of the best choices for pushing avocados into cooler climates.

Partly self-fertile
RipensAug-Oct (late summer-fall)Zones8-11Diseasesusceptible to Phytophthora root rotSizecompact standard, semi-dwarf 10-15 ft
Pollinationflower type A (self-fruitful; benefits from a type B)

rich, classic Mexican-avocado flavor; medium green-purple fruit — Among the most cold-hardy avocados (to roughly 15F) on a naturally compact tree, ideal for Gulf Coast and marginal yards.

Partly self-fertile
RipensJul-Sep (summer-early fall)Zones8-11Diseasesusceptible to Phytophthora root rotSizestandard, upright and narrow 15-25 ft
Pollinationflower type B (pairs with cold-hardy type A varieties)

rich, nutty; distinctive thin purple-black skin — A cold-hardy (to ~18F) type-B tree that gives Gulf-South growers a pollinizer partner for Mexican type-A avocados.

Reed

Partly self-fertile
RipensJul-Oct (summer-fall)Zones9-11Diseasesusceptible to Phytophthora root rotSizestandard but upright and columnar 15-20 ft
Pollinationflower type A (sets well alone; type B improves yield)

rich, buttery, high quality; large round green fruit — Its upright, space-saving habit and summer-ripening large fruit make it a favorite single-tree pick for warm-winter yards.

good, mild-to-rich; medium green pear-shaped fruit — The only genuine dwarf avocado, well-suited to containers and small gardens, though frost-tender to about 30F.

Avocado needs a pollination partner — plant two genetically distinct trees (two different cultivars, or a cultivar plus a seedling).

VIII

Questions

Avocado questions, answered straight.

Why isn't my avocado fruiting?

Most often: it has no genetically distinct partner nearby. Avocado is only partly self-fertile, so a lone plant sets a light crop at best — type a + type b flowering for best set (one tree fruits lightly alone). Plant a second, unrelated one nearby; two different cultivars, or a cultivar plus a seedling, is the classic pairing.

Is avocado safe for kids and pets?

Avocado is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. One caveat on this one: Safe for people; leaves/bark/pit are dangerous to BIRDS, horses and livestock (persin). For dogs and cats the real risks are GI upset, pancreatitis from the fat, and choking on the pit — not persin poisoning. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.

When do you harvest avocado?

Fruit holds ON the tree for months — 'store on the tree', pick as needed; softens only after picking.

How do you propagate avocado?

Grafted, or from cuttings/layering (seed won't come true).
