Pinkerton Avocado is a highly productive, cold-hardy cultivar prized for its large, pear-shaped fruit with exceptionally high oil content and rich, nutty flavor. A Guatemalan-type avocado, it is known for its distinctive long neck, small seed, and thick, pebbly green skin that ripens to a dark greenish-purple . The tree is vigorous, upright, and bears heavy crops from late fall through spring, making it a valuable addition to home orchards in mild climates. With good cold tolerance (down to 28-30°F) and self-pollinating A-type flowers, it is one of the more reliable and rewarding avocado varieties for home growers.

Knowing how we measure the size?

When browsing our plants, you may notice size terms such as Gallon, Multi, or Stand. These describe how a plant is grown, containerized, or structured at the time of sale — not just its height. Understanding these terms will help you choose the right plant for your space and expectations.

🌱 Gallon Size (Container Size)

Gallon refers to the size of the nursery container the plant is currently growing in (e.g. 1 Gallon, 5 Gallon, 15 Gallon).

A larger gallon size generally means:
- A more established root system
- A sturdier plant
- Faster visual impact after planting
Example:
- 5 Gallon: Ideal for residential gardens, easy to handle, good balance of value and maturity
- 15 Gallon: More mature, provides quicker results in the landscape

Note: Gallon size does not guarantee a specific height, as growth varies by species.

🌳 Multi (Multi-Trunk / Multi-Branch Form)

Multi indicates the plant has multiple trunks or main stems growing from the base.

Commonly used for:
- Ornamental trees
- Feature plants
- Japanese maples, olives, crepe myrtles, etc.
Why choose Multi:
- Fuller, more sculptural appearance
- Strong visual presence even at younger ages
- Popular for design-focused landscapes

🌲 Stand (Single-Trunk / Standard Form)

Stand (short for Standard) refers to a single, dominant trunk with a raised or naturally formed canopy.

Commonly used for:
- Shade trees
- Street trees
- Orchard and structural plantings
Why choose Stand:
- Clean, classic tree form
- Easier clearance for walkways and lawns
- Preferred for long-term structure and uniformity

🌿 Choosing the Right Size

If you want instant impact → larger Gallon, Multi form
If you want long-term structure → Stand form
If you want flexibility and value → mid-size Gallon containers

If you’re unsure which size or form fits your project, our team is happy to help you select the best option based on your space, timeline, and design goals.

Q: How does 'Pinkerton' compare to 'Hass' avocado?
A: 'Pinkerton' fruit is larger, more elongated, and has a thinner, more pebbly skin than 'Hass'. Its flavor is similarly rich and buttery, with high oil content, though some describe it as slightly sweeter. 'Pinkerton' is more cold-tolerant, produces heavier crops, and has a longer harvest season (November-April) . 'Hass' remains the standard for commercial production, but 'Pinkerton' is an excellent choice for home orchards.

Q: How much cold can it tolerate?
A: Mature 'Pinkerton' trees can tolerate brief temperatures down to 28-30°F (-2 to -1°C) . Young trees are more sensitive and require protection from frost. It is best suited for USDA zones 9-11 but can be grown in warmer parts of zone 8 with careful site selection and winter protection .

Q: Is it self-pollinating?
A: Yes, 'Pinkerton' has Type A flowers and is self-fertile, meaning a single tree will produce fruit. However, planting with a Type B variety (such as 'Bacon', 'Fuerte', or 'Zutano') can significantly increase yields due to cross-pollination .

Q: When is the fruit ready to harvest?
A: 'Pinkerton' fruit typically matures from November through April . Unlike some varieties, the fruit holds well on the tree, allowing for harvest over several months. The fruit is ready when the skin begins to darken slightly and yields to gentle pressure. It does not ripen fully on the tree; pick when mature and allow to ripen at room temperature .

Q: How should I fertilize and care for it?
A: Fertilize in spring and summer with a balanced citrus/avocado fertilizer containing nitrogen, phosphorus, potassium, and micronutrients like zinc . Avocados have shallow root systems; mulch around the base (keeping mulch away from the trunk) to retain moisture and regulate soil temperature. Water deeply but infrequently, allowing the soil to dry slightly between waterings .
