Botanical illustration of Avocado

Everyone sprouts the pit on toothpicks; almost nobody eats an avocado from it. The honest path to homegrown guacamole is a grafted Avocado — 'Mexicola' and other hardy Mexican types — and a curious quirk sweetens the deal: the fruit stores on the tree for months, softening only after you pick.

In a big pot it plays glossy patio tropical all summer and bright-window houseplant all winter, with the classic pit-on-toothpicks still worth doing as kid science on the side. Fruit set improves with a partner tree — and keep it away from pet birds. Start the ambition now.

What each band means

  • Bloom — flowers open — pollinators working, frost on blossoms is the danger.
  • Prune — shape it now — cuts heal cleanly and structure is visible.

These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.

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.

Avocado · Varieties & cultivars

Best avocado varieties & cultivars

There are far more than these — the ones below are the named varieties of avocado people actually plant.

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.

9 varieties

Hass

Also known as Hass Avocado

Partly self-fertile

Ripens
Spring through summer (Apr-Sep in CA)
Zones
9-11
Disease
susceptible to Phytophthora root rot
Size
standard 15-30 ft (prune to keep smaller)
Pollination
flower 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.

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).
