Fruits, Nuts & Perennial Crop CalendarsAvocado Calendar by Region
Avocados are grown in several very different climates, so a single calendar does not exist. What stays constant is how the tree flowers, how fruit matures and how frost is handled.
Key points
- Avocado timing depends on region and variety, so use local guides.
- Frost sensitivity drives site choice and protection.
- Avocados ripen after picking, but only if mature.
- Check quarantine rules before moving trees or fruit.
Why does avocado timing vary so much by region?
Avocado types come from different races, and each suits a different climate. Some tolerate more cold than others, and tropical types do better in humid, frost-free areas. California, Florida and Hawaii each grow different varieties, and maturity seasons differ among them.
For that reason, this guide avoids calendar dates. For local timing, use the University of California Agriculture and Natural Resources, University of Florida IFAS or University of Hawaii CTAHR guides for your region.
A grower in a cool coastal area and one in a humid tropical area may both grow avocados but follow very different schedules. Ask a local grower or adviser about the varieties that have done well near you.
What is the A and B flower type system?
Avocado flowers open twice, first as one sex and then the other, on a daily rhythm that differs between two groups called type A and type B. Trees of one type often benefit from a nearby tree of the other type for better pollination, though many varieties set fruit alone.
Check your variety and ask extension whether a second tree improves fruit set locally. Bees and other insects are the main pollinators, so protect them during bloom.
How does frost affect avocados?
Avocados are frost sensitive, especially young trees, and different varieties tolerate different cold. A freeze can damage leaves, flowers and fruit, and a severe one can kill branches or trees. Site selection and protection are the key tools.
Plant on slopes where cold air drains away, avoid frost pockets, and protect young trees in their first winters. Ask extension about local practices, and check forecasts from the National Weather Service.
Consider a windbreak and a site with good sun exposure, because wind damage and cold both reduce fruit. Wind can also knock fruit from trees.
- Avoid low frost pockets
- Protect young trees in early winters
- Check forecasts when cold fronts approach
When do avocados bloom, set and mature?
Trees bloom heavily, but only a small share of flowers become fruit. Fruit develops over many months, and some varieties hold mature fruit on the tree for a long period. That holding ability lets growers spread harvest over weeks or months.
Maturity differs from ripeness. A mature avocado will soften and ripen after picking, while an immature one will shrivel without ripening. Extension offices publish maturity tests for local varieties.
Keep notes on bloom dates, fruit set and mature fruit tests. These records help you decide how long to leave fruit on the tree and when to pick.
How do you know avocados are mature enough to pick?
Fruit color may not change on the tree, so color is a poor guide in many varieties. Growers rely on measures published for each variety, and home growers can ask extension for the simplest local test. A common practice is picking one fruit, letting it sit at room temperature and noting whether it softens evenly.
If it shrivels or turns bitter, the crop is not ready. Wait a couple of weeks and test again, using fruit from different parts of the tree.
Avoid picking all fruit at once. Pick what you can use over a few weeks if your variety holds well on the tree, and check with extension on how long that is safe.
How should you water, feed and prune?
Avocados have shallow roots and dislike waterlogged soil. Good drainage and mulch are important, and watering should be steady but not constant. Salt in irrigation water can harm trees, and some regions have water quality concerns.
Feed by soil test and local advice, since nutrient management rules vary by state. Prune lightly to open the canopy and remove dead wood, and avoid heavy cuts that expose bark to sunburn.
Mulch deeply, but keep it a few inches from the trunk. A layer of leaf mulch builds soil life and helps avocados' shallow roots.
What pests, diseases and regulations matter?
Root rot, fruit pests and some quarantine issues affect avocado growers in several regions. Movement of plants and fruit may be restricted, so contact your state department of agriculture before buying or moving trees.
This guide gives no product names or rates. Follow your extension guide, apply only labeled products as directed, observe pre-harvest intervals and protect pollinators.
Ask your state department of agriculture whether any regulated pests exist in your area before buying trees or sharing fruit.
