Product Description

Compact, Hardy Hazelnut Tree

The Theta Filbert Hazelnut Tree, an Oregon State University introduction, is stacked with positive features. From its compact and attractive shape to its flavorful, medium-sized sized nuts, it’s the perfect piece for yards of all sizes and styles.  

And speaking of size, the Theta Filbert Hazelnut only grows to be about 8-10 feet tall, meaning it’ll conveniently fit into smaller landscape spaces. Its manageable habit means there’s no need to worry about it taking over your yard.

But don’t fret - its smaller size doesn’t detract from its impressive beauty! With large, thick green leaves and striking, long, yellow catkins making an appearance in late fall, this stunning tree delights with growth nearly all year long.

Plus, it’s boldly flavored, buttery, healthful nuts will be ready to harvest in September, just in time for delicious fall recipes! Add them to baked goods and desserts, breakfast dishes and salads, or eat them by the handfuls.

What’s more is that the Theta Filbert Hazelnut is tolerant of heat and humidity and resistant to pests and diseases, including Eastern Filbert Blight for an all-around low-maintenance variety.

Add the perfectly-sized, highly rewarding Theta Filbert Hazelnut Tree to your landscape to enjoy its good looks and heavenly hazelnuts!

NOTE: This product cannot ship to Oregon.

Planting & Care

1. Planting: These trees can tolerate partial shade but prefer around 6 hours of sunlight daily. Avoid planting your tree in areas of your yard that are prone to flooding...well-drained soil is best.

Dig a hole that’s just as deep as the root ball, and three times as wide. Make sure that your tree is straight and that the root collar is level with the surrounding ground. Backfill your hole and gently tamp the soil down as you go to eliminate air pockets. Finally, water and then mulch the area to deter competing growth and to preserve soil moisture.

2. Watering: Feel your soil every few days. Once it feels like it’s close to drying out about 3 inches down, give your tree a slow drink of water by holding a hose to its base and counting to 30 seconds.

3. Fertilizing: We suggest waiting two to three years before fertilizing. To give your tree a boost, feed with well-balanced organic fertilizer, like formula 10-10-10, in the late winter or early spring.

4. Pruning: The best time to prune is in the late winter or early spring when your tree is still dormant. Be sure to remove any dead or broken branches, as well as crisscrossing or rubbing branches.

*Note: Nut production is maximized in growing zones 6 and above. If you live in a hotter zone, you may see smaller nut harvests.
