The Hass avocado is the most popular avocado variety in the world, making up most of the commercial production. It originated as a seedling grown by Rudolph Hass, a postman in La Habra Heights, California, in the 1920s, and was patented in 1935. Hass also appears in the family tree of several other popular varieties, including Pinkerton and Esther. It forms a vigorous, spreading tree that can grow quite large, but can be kept to a manageable size with light pruning after harvest.
Hass is known for its thick, bumpy skin, creamy texture, and the changing of its skin colour from green to purple/black as it ripens. It is considered a "high-fat" avocado, meaning it has a higher fat content than some other varieties. The Hass avocado is also known for its rich, nutty flavour and is often used in guacamole, sandwiches, and other dishes. Fruit is medium sized, commonly 200 to 300 g each. Hass has a long fruiting season, starting in spring, through summer and into early autumn.

Our trees are grafted and will begin flowering in spring. Hass is an A flowering type. Avocado trees in our climate are self fertile, but produce more fruit if 2 are planted near each other with opposing flower types. In this case, best planted near a B type, like Fuerte, Bacon, Hashimoto, Zutano or Ettinger, or any other B type tree.
Avocado care guide
Just arrived? Keep your tree in a sheltered, semi-shaded spot for 2–4 weeks before planting. See our acclimation guide.
1. Drainage is everything
More avocados die from wet roots (Phytophthora root rot) than anything else. Plant on a mound 40–60 cm high (go higher on heavy clay) using a free-draining mix. Never dig a hole into clay; it fills with water like a bucket. Keep the graft union above the soil.
2. Water the root ball, not the calendar
For the first year, the root ball dries out faster than the soil around it. Check 5 cm down and water deeply only when it's dry. In summer that's usually once or twice a week, more often on sandy soil or in a heatwave. In winter, you'll barely need to water.
3. Mulch thick, but keep it off the trunk
Put 10–15 cm of coarse wood chip or bark out to the drip line, with a 10 cm gap around the trunk. Avocado feeder roots are shallow, so don't dig or plant anything around the base, and keep lawn well away.
4. Feed little and often
Give small feeds of a balanced fertiliser (one with zinc and boron) in spring, summer and early autumn. Don't feed in winter. Spread it at the drip line, keep it 40 cm from the trunk, and water it in.
5. Stake and tie it properly
Young avocados need firm support against the wind from the day you plant. Put in two big, sturdy stakes, one on each side of the tree. Tie soft strips of woollen cloth across between the two stakes, looping them around the trunk, at two heights. This holds the tree firmly in the middle, and the soft cloth won't rub or cut into the bark.

6. Shelter young trees for 2–3 years
A windbreak around a young tree really helps it grow faster. We wrap clear plastic around four tall stakes to make a sleeve around each young tree. Leave the sleeve open at the top and keep it a little below the top of the tree, so the trunk and lower branches are sheltered while the top still gets plenty of sun and air. Windbreak cloth also works well in exposed spots.

Open at the top and sitting just below the top of the tree, so the trunk is sheltered while the top still gets sun and air.
Use frost cloth when frost is forecast (young trees are damaged around -1 to -2°C). Paint exposed trunks with white water-based paint diluted 50:50 to prevent sunburn.
7. Let the tree grow before it fruits
Pick off any fruit in the first 1–2 years so the tree puts its energy into branches and roots. Only prune to remove dead wood or keep the tree in shape.
What's normal (don't panic)
- Old leaves dropping in spring: normal. Avocados shed old leaves as they flower and push new growth.
- Brown, crispy leaf tips: usually salt or fertiliser burn, or dry roots. Flush with a deep watering and ease off on feeding.
- Most flowers and tiny fruit dropping: normal. Avocados produce thousands of flowers and set only a few.
- Yellowing leaves and wilting in wet soil: a root rot warning sign. Stop watering and check drainage.
