It is important to pick up the nuts every day so that the weevil does not escape and go into the soil. Once in the soil, they will dig down and overwinter, re-appearing in the spring to lay eggs in your hazelnuts.
Hazelnut is susceptible to a fungus known as Eastern Filbert Blight, which has decimated orchards in the Pacific Northwest. Infected branches will wither, and trees will lose leaves. Later, bumps form on twigs that rupture fungal spores in August or July. Eventually, the bush will die. To spot, keep an eye out for cankers on the branches. You can control the fungus with an anti-fungal application four times a year. These days, there are so many cultivars that are immune to the fungus that we recommend you start out with one to save yourself any trouble in the future.
Hazelnuts are also susceptible to filbertworm, which acts similar to the nut weevil, boring a hole into the shell of the nut. This can be controlled in a similar way. Hazelnut mosaic can cause leaf yellowing and may reduce yields. Thermotherapy is the most effective way to treat the virus.
Hazelnuts are attacked by insects called Filbert or Hazelnut aphids. They are medium to small insects that feed on the leaves and husks of the plant, reducing the fill and size of the nut. Heavy infestations need to be treated using an insecticidal spray or by introducing Trioxys pallidus, a parasitic wasp that controls aphids. Tent caterpillars impact hazelnuts and many other trees in the Pacific Northwest.
You can spot them by the large egg masses on twigs. You can remove the masses or spray them off using a strong stream of water. Rake up and dispose of any egg masses. Like many nut trees, hazelnuts can also be attacked by root rot, powdery mildew, bacterial blight, and cankers. There are hundreds of hazelnut cultivars, so when you decide on what to grow, consider the pests in your area and select a variety that is resistant.
Nitrogen-fixing plants like crimson clover or white clover, or plants that attract pollinators and improve soil like comfrey make good companions for growing hazelnuts. Primrose, coriander, currant, asparagus, and garlic also make good companion plants for a hazelnut.
Hazelnuts start producing three to five years after planting. Nuts are usually harvested in August and September, or as late as October depending on your agricultural zone and variety. As the leaves and burrs start to turn color, you can begin to harvest. Keep in mind that hungry animals may make off with your bounty if you let them fall.
Otherwise, the nuts are easy to shuck from the burr. Simply shake the tree. Mature plants yield about one to two gallons of nuts per bush or up to 20 pounds. The nuts need to dry for several days before storing. You can lay them out on a tarp in sunny weather or on a rack inside. You can store them in the freezer for up to six months. Roasting hazelnuts are easy. Just lay them out still in the shell, in a single layer on a baking sheet.
Roast at degrees for thirty minutes. I stir them up a little about halfway through. Roasted nuts can store up to two years. Now for the best part of growing hazelnuts: cooking them. Hazelnuts can be eaten raw or cooked. Like most nuts, hazelnuts are healthy for you. They are rich in many essential nutrients including 14 grams of protein per serving. Hazelnuts are rich in B vitamins and also have high amounts of thiamine B1 Niacin B3.
Hazelnuts have heart-healthy omega-6 and omega-9 fatty acids. They are high in fiber and antioxidants particularly proanthocyanidins which have been shown in studies to fight cancer. I think hazelnuts are great for breakfast. They are a nutritious start to the day and make my sweet tooth happy.
I like to mix them with fruit and add them to oatmeal. For Sunday breakfast when I usually make something fancy for my family, I like to top off pancakes with roasted hazelnuts or pralines. If you are a southerner, you know all about pralines. Stir until dissolved. Stir the mixture constantly until everything is melted and has turned a caramel color. Toss in your hazelnuts and bring to a soft boil. Stir occasionally. Once the syrup has reduced, scoop out the nuts and place them on parchment paper to dry.
Hazelnuts are a nice plant for landscaping. They have a pleasant shape and have showy catkins in the spring. The leaves are a dark, rich green and serrated and they have pretty red and orange fall foliage. Another advantage of the hazelnut is they are great for hedgerows because they form a dense screen without growing too high or wide. They can also handle wind, so they make a good windbreak.
Hazelnut wood has a long history of use for fencing, walking sticks, fishing rods, and baskets. The long, malleable branches are perfect for coppicing in wattle fences and thatching spars. They were traditionally used for fences in Europe and early America. Leaves from a hazelnut bush make good fertilizer. Use the leaves as mulch to help suppress weeds and make plants to thrive.
Oil from the hazelnut can lower cholesterol and is a powerful antioxidant. This can be seen in an over-the-top exaggerated form in the amazing cultivar Corylus avellana 'Contorta,' also known as most commonly known as Harry Lauder's Walking Stick.
The common hazel is a relatively carefree plant. One important thing to note is that depending on your intended use, you will need to invest in two trees, a male and a female, if you want to produce nuts.
Hazels are monoecious and not self-pollinating. If you want a self-pollinating hazel, there are hybrid varieties available. Male and female trees are readily available online from specialty retailers specializing in fruit and nut trees. You may or may not end up with bit of shell litter under your trees if you have multiple trees, which might bother you.
If it does, you may need to clean up the shell refuse that your friendly critters left under the trees. Shells aren't the only thing they release: hazelnut trees are prolific pollinators. Placing a hazel in a location that receives full sun most of the day will give you the best yield of flowers and nuts if that is what you are trying to achieve. It will tolerate part shade as well, but you will see a decrease in flower production. The hazel tree is very adaptable, but it is best to avoid densely packed soils, clays, or rocky soils.
Its preference would be to grow in sandy loams that drain rather well. Keeping your hazel tree watered is important to ensure profuse flower and nut production. It will not tolerate drought and will need supplemental watering to remain a viable producer if you look forward to it fruiting during dry periods. Water it using the same standard rule to establish 10 gallons per inch of trunk diameter after planting.
Using this method will keep your hazel green and blossoming in even the driest of weather. Hazels are great at existing in temperate areas. There are a number of insects that also enjoy eating hazelnuts. Keep your eye out for these common pests to reduce damage to your crop. The larvae overwinter in the soil, emerging as moths in spring and laying eggs on hazelnut husks. The young larvae that emerge then enter and feed on the developing nuts, tunneling their way through and completely destroying the kernels.
Try incorporating lots of flowering perennials like dill , daisies, and marigolds to encourage the presence of beneficial insects and reduce pests. Large-scale growers often use mating disruption pheromones to reduce the population of acorn moths in their orchards.
The adult beetles munch on buds and leaves in the spring, damaging foliage, and lay their eggs in the developing nuts in early summer. The infected nuts do not drop, and often end up being harvested along with the healthy remainder of the crop, at best creating a nuisance for harvesting, and at worst effectively ruining the crop. One way to remove weevils naturally is to place tarps under the trees during the late summer after a rainstorm, and shake each tree until the adult weevils fall to the ground.
They will remain still for a few minutes after falling, at which point they can be collected in a bucket of soapy water and disposed of. The diseases that tend to plague filberts are those that thrive in wet soils. You can do a lot to mitigate disease risk by planting your trees in places that are not waterlogged, with well-draining soil.
The fungus Anisogramma anomala causes cankers to form on branches and blossoms, leading to rapid wilting and dieback of foliage and branches.
Cankers appear as dark, raised lumps on infected plant tissue. Remove and dispose of branches with cankers. You can learn more about Eastern filbert blight in our guide here. Leaves infected with this fungus will become discolored and drop, followed by branch die-off and the eventual death of the entire plant. Yellow mushrooms may also appear at the base of the plant. Once this disease takes hold, plants need to be removed and disposed of. The best way to prevent armillaria is to plant resistant rootstock.
Caused by the bacterium Xanthomonas campestris pv. This is a particularly problematic disease in the Pacific Northwest. Remove and dispose of diseased branches. Bacterial canker, caused by Pseudomonas avellanae , is a particular problem in European hazelnuts.
New growth withers, and buds and leaves die, remaining attached to the tree after healthy leaves drop in the fall. Cankers can also be seen, appearing as gray areas on the bark. When the plant is mature enough for the first harvest, the nuts will drop from the branches as they ripen in the autumn. See our complete guide for harvesting hazelnuts here.
Dry the nuts by laying them on trays and putting them in a warm place out of the sun for a few weeks, turning the nuts every couple of days. Once they are fully dry, scrape off the papery husks. You can shell them or store them in the shells. In the shell, they will keep at room temperature for several months.
Eat shelled nuts within a few weeks or refrigerate them for up to a year. Whether roasted on an open fire, toasted and served atop a salad, or crushed and sprinkled over a decadent chocolate cake, having a stock of homegrown hazelnuts around the kitchen sure opens up some interesting culinary possibilities!
