Pick almonds when the green hulls split open and the shells inside are dry and mature—not simply when the nuts reach full size. In most climates, harvest falls in late summer or early autumn, but timing varies by variety, weather, and location. A few checks on the tree help you avoid immature kernels, mold, and losses to pests. You’ll need a way to collect the nuts and a dry place to finish drying them after harvest.
What You’ll Need
- A clean tarp, sheet, or shallow collection bins to catch fallen almonds.
- A basket or ventilated container for gathered nuts.
- Gloves and, if needed, a long-handled pole for gently shaking reachable branches.
- A dry, shaded, well-ventilated place with screens or trays for drying.
- A nutcracker or small tool for checking a sample shell and kernel.
Step-by-Step
- Learn your variety’s usual harvest window. Note the variety and its typical harvest timing for your region, then use that as a rough guide, not a fixed date. Almonds ripen at different times depending on variety, local temperatures, rainfall, and tree health. In many Northern Hemisphere growing areas, harvest is from August through October; Southern Hemisphere timing is generally around February through April. Local extension services or an experienced nearby grower can offer a more precise estimate.
- Watch for hulls beginning to split. The green, fleshy hull around the hard shell usually opens along its seam as the nut matures. Look for hulls that are drying, turning tan or brown, and separating from the shell. Check several parts of the tree: nuts on the outside and upper branches may mature before those in shaded areas. A few open hulls are an early signal to start checking, not necessarily a sign the whole crop is ready.
- Check a representative sample. Take several nuts from different branches and positions. The hull should come away readily, and the hard shell should feel firm and developed. Crack a few shells: mature kernels are full-sized, firm, and have the color and flavor typical of the variety. If kernels are soft, watery, shriveled, or poorly filled, leave the remaining nuts on the tree and check again in several days.
- Look for natural drop, but don’t rely on it alone. Mature almonds often fall as hulls open and dry. A number of sound nuts on the ground can signal that harvest is close. However, fallen nuts may be old, worm-damaged, or wet, so inspect them rather than treating every ground nut as a good one. Pick up sound fallen almonds promptly, especially before rain or wildlife can damage them.
- Choose a dry harvest day. Avoid picking in rain or when the nuts, foliage, or ground are wet. Damp hulls and shells are more likely to mold during drying. If rain is forecast and many hulls are already open, harvesting before it arrives may be preferable; move the crop straight into a dry, airy place.
- Collect the crop gently. Spread a clean tarp beneath the tree. Shake branches carefully by hand or with a pole so ripe nuts fall onto the tarp; avoid striking or breaking limbs. Work in sections and gather nuts from the tarp and ground into ventilated containers. Do not leave a deep pile of fresh almonds in a closed bucket or plastic bag, where heat and moisture can build up.
- Separate damaged or questionable nuts. Remove leaves and twigs, then discard nuts with mold, insect holes, rancid or musty odors, or visibly damaged kernels. Keep nuts that fell onto dirty or contaminated ground separate from clean harvest. Do not taste moldy nuts to judge whether they are safe.
- Dry the almonds promptly. Spread the nuts in a single layer on screens or trays in a dry, shaded, well-ventilated area. Turn or stir them periodically and protect them from rain, dew, birds, and rodents. If hulls are still attached, remove them when they loosen easily; don’t store wet, hulled nuts in a heap. Drying time varies with humidity and airflow, so judge by dryness rather than a set number of days. The kernels should be crisp, not pliable, and shells should be dry before storage.
- Store only fully dry almonds. Keep dried almonds in clean, airtight containers in a cool, dark place, and label them with the harvest date. For longer storage, refrigerate or freeze them in well-sealed packaging to slow rancidity. Check stored nuts periodically for moisture, insects, or off odors; discard any that develop mold or a musty smell.
Common Mistakes
- Harvesting by calendar alone: A typical month is only a starting point. Confirm maturity by hull splitting and by checking kernels.
- Picking when only a few hulls have opened: Early nuts may be ready while shaded or later-ripening nuts still need time. Sample across the tree and harvest in stages if maturity is uneven.
- Waiting until every nut falls: Nuts left on the ground can be lost to insects, animals, rain, or decay. Collect ripe fallen nuts promptly and shake the tree when most of the crop is ready.
- Drying in direct sun or in a pile: Excess heat can harm quality, while poor airflow traps moisture. Use a single layer in shade with good ventilation.
- Sealing nuts before they are dry: Trapped moisture encourages mold. Make sure shells and kernels are thoroughly dry before packing them for storage.
Tips
- Check a few nuts every two or three days as the crop approaches maturity; increase checks after a warm, dry spell.
- Use a tarp to collect nuts cleanly and to make it easier to see whether the tree is still dropping many sound almonds.
- Harvest in batches if exposed branches are ready before shaded ones. This reduces the chance of leaving ripe nuts too long or taking immature ones.
- Keep notes on hull-splitting dates and harvest dates by variety. Your own records become more useful than a general calendar over time.
- If you are unsure about drying, crack a sample after it has dried. A crisp kernel is a better sign of readiness for storage than a dry-looking hull alone.
Troubleshooting
- Hulls are still closed but the usual harvest month has arrived: Wait and check again. A cool season or a later variety may delay ripening. Do not force open the hulls as a shortcut; check sample kernels for maturity.
- Hulls are splitting but kernels look underdeveloped: Leave those nuts on the tree if weather and pest conditions allow, then sample again in a few days. Different nuts on one tree can mature at different rates.
- Almonds are falling before you are ready: Put a tarp under the tree, collect sound nuts frequently, and inspect for insect damage. If most hulls have split, shake remaining ripe nuts rather than waiting for all of them to drop.
- Rain arrives during harvest: Collect any ripe nuts promptly and spread them out indoors or under a dry, ventilated shelter. Remove visibly moldy nuts and do not seal the rest until fully dry.
- Kernels become moldy or smell musty: Do not eat them. Discard affected nuts, inspect the rest of the batch, and improve drying and storage conditions. If mold is widespread, discard the entire questionable batch.
- Some nuts are shriveled or empty: Separate and discard them. Poor filling can result from pests, pollination problems, water stress, or other growing conditions; it is not corrected by further drying.
Frequently Asked Questions
What month are almonds usually ready to pick?
In many Northern Hemisphere regions, almonds ripen from late summer into early autumn, often August through October. The exact timing depends on variety and local conditions, so check the nuts rather than relying on the month.
Can I pick almonds before their hulls split?
Usually, it is better to wait until hulls begin opening and sample kernels are firm and fully developed. A closed hull alone does not prove a nut is immature, but harvest signs should be checked carefully before picking early.
Should I wait for almonds to fall from the tree?
No. Natural drop is a useful maturity clue, but waiting for every nut to fall can expose the crop to pests, animals, and weather. Collect fallen nuts promptly and shake the tree when most of the crop is ready.
How can I tell if almonds are dry enough to store?
There is no reliable single drying time because humidity and airflow differ. The shells should be dry, and kernels should be crisp rather than soft or pliable. Dry them in a ventilated single layer and check a sample before sealing the crop.
Can almonds ripen after picking?
They do not continue normal ripening off the tree. Drying removes moisture from harvested nuts, but it will not make an immature, poorly filled kernel mature. Confirm kernel development before collecting the crop.
What should I do with almonds that have mold?
Discard moldy nuts and any with musty odors; do not taste them. Inspect nearby nuts and the storage area, and make sure sound almonds are fully dry before storing.
