Conveniently-Sized Hazelnut Can Produce in 1 Year

Why Theta Filbert Hazelnut Trees?

It's a classic tree, now grown for optimal benefits. Not only can it produce fruit in its first season, under optimal conditions, but it's also carefree. What else makes the Theta Filbert a must-have?

  • It's a beautiful tree with large, thick green leaves.
  • It's resistant to pests and diseases, including Eastern Filbert Blight and tolerant of heat and humidity.
  • And it's conveniently-sized, topping out at 8 to 10 feet in height.

Experts at Oregon State University set out to engineer the perfect Hazelnut Tree, and the result was the Theta Filbert. Aside from the numerous qualities of the tree itself, the hazelnuts are some of the best we've seen. Gorgeous, glistening, copper-colored hazelnuts abound. Created to produce high yields, the Theta's nuts fill their husks in great numbers. What's more, the Theta's flowers will pollinate and help increase production in your Jefferson Filbert Trees as well.

Pollination Info

Theta Filbert Hazelnut Pollination

Theta Filbert Hazelnuts are not self-fertile. You will need to plant another variety to achieve fruiting. Below are the most effective pollinators we have chosen for your area...

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.
