Convenient Sized Hazelnut Tree

Theta Filbert has a lot going for it

Here's Why:

  • Beautiful tree with large, thick green leaves
  • Resistant to pests and diseases including Eastern Filbert Blight
  • Tolerant of heat, sun and humidity
  • Convenient sized tree topping out at 10 feet

Is this the Perfect Nut Tree?

When the experts at Oregon State University set out to engineer the perfect Hazelnut tree, the result was the Theta Filbert. Conveniently sized for ease of harvesting, resistant to Filbert Blight and tolerant of harsh conditions, the Theta seems to have it all. Covering the tree are thick, green cabbage-like leaves. 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.

The Quintessential Hazelnut Has Arrived

One look at a Theta Filbert hazelnut and you can see that this is a nut of the highest quality. But one taste and you'll know it's among the best available hazelnuts in the world. As September rolls in, you'll be ready to harvest scores of medium sized nuts, each appearing as perfect as the other. The flavor is rich, buttery and exactly how you'd imagine the ideal hazelnut to taste. Your family will enjoy them fresh off the tree or used to create a diversity of culinary treats for many seasons to come.

Theta (Hazelnut) Trees require a pollinator to produce nuts. For best results, pair with the Jefferson Filbert (Hazelnut.)

With all these incredible benefits, ordering the Theta Filbert hazelnut tree just makes sense. Don't delay.

Planting & Care



It's Easy to Plant & Care for Your Theta Filbert Hazelnut


Theta Filbert Hazelnut Planting Diretions

The Theta Filbert Hazelnut (corylus avellana 'Theta') is a cold hardy, dwarf variety hazelnut tree that produces some of the richest, buttery flavored nuts that most consider the idea hazelnut. This full to partial sun loving tree is commonly planted in USDA growing zones 5-8 and is best planted with a cross pollinator as hazelnut trees are not self-fertile. The nuts are conveniently sized to make for ease in harvesting them when the time comes. Their foliage is a thick, cabbage-like green that really make those blooms pop when they emerge! One of the best qualities of the Theta is its ability to naturally resist disease, including the infamous “Eastern Filbert Blight.” The dwarf maturity of 8-10 feet tall and 6-8 feet wide also makes it easy to grow in small spaces.

Seasonal information: Hazelnut trees are tough trees that can be planted all year, as long as the ground isn’t frozen. If you plant your tree during the summer, especially during a heat wave of drought then give your tree extra water. The best time to plant is in the fall, six weeks before the first frost so your tree can get rooted into the ground before winter, or in the spring six weeks after the final frost, giving it time to become established before summer heat sets in. Keep in mind that planting during the summer still gives your tree enough time to get rooted in before the winter.

Location: When deciding where to plant your Hazelnut trees look for an area that receives full sunlight, because this is where hazelnuts will grow best. These nutty trees can tolerate partial shade, and you’ll still receive an abundant harvest year after year if your tree gets at least six hours of sunlight a day. Avoid planting your tree in areas of your yard that are prone to flooding or that collects standing water or large puddles for extended periods of time.

Planting Instructions:
1) Once you have the perfect location scouted out, dig a hole that’s just as deep as the root ball, and three times as wide.
2) Next, take a shovel or pitchfork and scrape around the sides of the hole to loosen the dirt up. Remove any debris like grass, dirt clumps, or rocks from the hole, and place your tree in it.
3) Make sure that your tree is straight and that the root collar is level with the surrounding ground.
4) Slowly back fill your hole and gently tamp the soil down as you go to eliminate air pockets.
5) Once the planting process is complete give your tree a long slow drink of water and then mulch the area to deter competing growth and to preserve soil moisture.

Watering: Keep the soil for your hazelnut tree moist, not over saturated. Feel your soil every few days, once it feels like it’s close to drying out give your tree a slow drink of water by holding a hose to its base and counting to 30 seconds.

Fertilizer: Hazelnut trees don’t require fertilizer often. We suggest waiting two to three years before fertilizing them. To give your tree a boost for healthy growth in the summer feed it some well-balanced organic fertilizer like formula 10-10-10 in the late winter or early spring.

Pollination: Hazelnut trees are not self-pollinating. They will need to cross pollinate with another variety in order to produce nuts. The Jefferson Filbert Hazelnut and the Theta Filbert Hazelnut make excellent pollination partners for each other.

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, damaged, or broken branches. Look for any crisscrossing or rubbing branches, prune them before they break on their own. When thinning your tree out to allow more air flow and sunlight to the center of your tree be sure to plan ahead and look at your tree to decide what to prune before starting, this will ensure that you don’t over prune your tree. Look for branches sticking straight upwards, these are non-fruit bearing branches that can easily be removed. Before pruning make sure that you have a sharp and sterile pair of hand pruners or loppers.

Weed Control: Weeds will compete with young trees for nutrients, so if you see any within 2 to 3 feet of the base of your tree it would be best to remove them. Remove them by taking a firm grasp on them and then pull them upwards out of the ground in a twisting motion. By spreading a layer of mulch around your tree that’s 2 to 3 inches thick it will prevent weeds from growing, and help the soil retain moisture.

Dwarf size. Choose hazelnut over almond because it is anticipated to produce nuts sooner.
