Pollination: Almond trees require cross-pollination for fruit set. Plant at least two different almond varieties or provide compatible pollinators nearby to ensure adequate pollination.
Harvesting: Almond nuts typically mature in late summer or early fall. Harvest nuts when the hulls split open and the shells begin to harden. Allow nuts to dry in a warm, well-ventilated area before storage or consumption.
By following these guidelines for growing and caring for almond plants, you can enjoy a bountiful harvest of delicious nuts year after year.
3 Steps for Propagating Almond Plant
Seed Propagation:
- Collect ripe almond seeds from mature fruits in the fall.
- Remove the outer hull from the seeds and rinse them thoroughly.
- Place the seeds in a container filled with moist sand or peat moss and store them in a cool, dark place for stratification. This mimics the natural winter conditions required to break seed dormancy.
- After 3-4 months of cold stratification, sow the seeds in well-draining potting soil or directly into the ground in late winter or early spring.
- Keep the soil consistently moist but not waterlogged.
- Germination usually occurs within 4-6 weeks. Once seedlings have developed several true leaves, transplant them to larger pots or their permanent growing location.
Grafting:
- Select a healthy almond rootstock suitable for your growing conditions. Common rootstocks include peach (Prunus persica) or plum (Prunus domestica) varieties.
- Collect scion wood from a desired almond cultivar during the dormant season. Scion wood should be approximately pencil-thick and have several buds.
- Prepare the rootstock by making a diagonal cut about 1 inch above the soil line. Make a matching diagonal cut on the scion wood.
- Join the scion wood to the rootstock using a compatible grafting technique such as whip-and-tongue or cleft grafting.
- Secure the graft union with grafting tape or rubber bands, ensuring good contact between the scion and rootstock.
- Keep the grafted plant in a warm, humid environment until new growth appears.
- Once the graft has successfully taken, gradually expose the plant to outdoor conditions and provide regular care.
Budding:
- Select a healthy almond rootstock and prepare it by removing any side shoots or branches.
- Collect dormant budwood from a desired almond cultivar, ensuring that the buds are plump and healthy.
- Make a T-shaped incision in the rootstock bark, carefully lifting the bark to expose the cambium layer.
- Insert a bud shield from the budwood into the incision, ensuring that the bud is positioned against the cambium layer.
- Secure the bud with budding tape or rubber bands, leaving the bud itself exposed.
- Keep the budded plant in a warm, humid environment until the bud begins to grow.
- Once the bud has successfully taken and grown into a new shoot, remove any competing shoots from the rootstock.
8 Benefits of Almond Plant
