Cracking the Code: Propagating the Chilean Hazelnut (Gevuina avellana)
The Chilean Hazelnut, or Gevuina avellana, isn’t your typical hazelnut. This evergreen beauty, native to the rainforests of Chile and Argentina, offers more than just delicious nuts – it boasts handsome, glossy foliage and a graceful weeping habit that can add year-round intrigue to your landscape.
If you’re intrigued by this unique tree and want to try your hand at propagation, you’re in luck! While a bit more involved than simply planting a seed, successfully growing Chilean Hazelnuts from scratch is a rewarding endeavor.
Two Paths to Chilean Hazelnut Propagation:
-
Seed Propagation – The Adventure Route:
-
Gather your supplies: Ripe Chilean Hazelnut seeds (look for fallen nuts with intact shells), a seed tray or small pots, seed-starting mix, and water.
-
Break the dormancy: Chilean Hazelnut seeds require a period of cold stratification to germinate. Place the seeds between moist paper towels inside a sealed plastic bag and store them in your refrigerator (around 4°C or 40°F) for 6-8 weeks.
-
Time to sow: After stratification, plant the seeds about an inch deep in your prepared seed tray or pots filled with the seed-starting mix.
- Patience is key: Germination can take anywhere from a few weeks to a few months. Keep the soil consistently moist but not waterlogged. Place the tray in a warm, bright location, but out of direct sunlight.

-
Cuttings – The Shortcut:
-
Choose wisely: Take semi-hardwood cuttings (slightly firm but not brittle) from healthy, mature trees in late summer or early fall. Cuttings should be about 4-6 inches long and taken from the current year’s growth.
-
Prepare the cuttings: Remove the lower leaves from the cutting, leaving 2-3 leaves at the top. Dip the cut end in rooting hormone powder (optional, but recommended).
-
Pot them up: Plant the prepared cuttings in a well-draining potting mix. Water thoroughly.
-
Create a humid environment: Cover the pot with a clear plastic bag or use a propagation dome to maintain high humidity. Place the pot in a bright location, but out of direct sunlight.
- Rooting success: In about 6-8 weeks, gently tug on the cuttings – resistance means roots are forming!
-
Nurturing Your Chilean Hazelnut Saplings:
Whether you chose the seed or cutting route, once your young trees have developed a good root system (usually after a year), it’s time to transplant them into larger pots or directly into the ground. Choose a spot with well-drained soil and either full sun or partial shade.
Reap the Rewards:
Propagating your own Chilean Hazelnuts might take patience, but the reward is well worth it. Imagine the satisfaction of seeing your very own tree, grown from seed or cutting, flourishing in your garden. And who knows, you might even be lucky enough to harvest some delicious, homegrown Chilean Hazelnuts in a few years!
