Establishment (Years 1-2)
2 yearsYoung tree develops primary scaffold branches and root system; minimal flowering; growth appears slower than other almond varieties
Keep soil consistently moist but not waterlogged; protect from frost; stake for support; prune to develop open vase structure; do not allow fruiting
Vegetative Growth (Years 2-3)
1-2 yearsTree continues branch development; foliage is dense and green; early flowers may appear but remain sparse
Continue structural pruning; maintain consistent irrigation; monitor for nutrient deficiencies (zinc, boron); apply dormant oil spray in winter
Flowering (Late Winter to Early Spring)
2-4 weeksDelicate pink to white blossoms appear in late February to March; blooms require pollinator activity; flowers last 2-3 weeks
Ensure compatible pollinator variety nearby (e.g., Butte, Nonpareil, or Padre); protect from late frosts; avoid heavy pruning during flowering; provide bee habitat
Fruit Development (Spring to Mid-Summer)
3-4 monthsSmall green drupes develop inside fuzzy hulls; nuts grow steadily from April through July; tree canopy provides dappled shade to developing nuts
Thin fruit if oversetting (crowding reduces nut quality); maintain deep irrigation (3-4 inches per week); monitor for pests; apply sulfur for fungal diseases if needed
Ripening & Harvest (August to September)
6-8 weeksHulls begin splitting and drying; kernels harden; color transitions from green to brown; nuts are ready to harvest when hulls split open
Reduce watering in late summer to concentrate flavors; harvest by shaking tree onto tarps when hulls naturally split; dry nuts at 100-110°F for 1-2 weeks; shell and store in cool, dry place

Harvest Tips
Marcona almonds typically begin producing in year 3-4 and reach full production by year 7-8. Harvest in late August through September when hulls naturally split open (indicating kernel maturity). Shake the tree using a trunk shaker onto tarps or catch cloths. Collect nuts promptly and dry at 100-110°F with good air circulation for 10-14 days until moisture content drops to 6-7%. Shell after drying to reveal premium kernels. Proper drying is critical for flavor development—inferior drying produces inferior taste.
Fun Facts
- 🌱 Marcona almonds originate from Tarragona in Catalonia, Spain, where they have been cultivated for centuries and remain a protected regional specialty with geographical indication status.
- 🌱 Marcona almonds produce larger kernels with thinner shells compared to common almonds—the kernels are so tender they can be eaten raw without skinning, unlike most other almond varieties.
- 🌱 A mature Marcona almond tree can be productive for 30-50 years, with some heritage Spanish orchards still producing premium nuts after 80+ years, making it an excellent long-term landscape investment.
