Hazel - Corylus spp, |
When we speak of Hazel we are generally referring to two species, Corylus avellana and Corylus maxima. The two species produce slightly different shape nuts and take different growth forms. Corylus avellana produces Hazelnuts and Corylus maxima produce Filberts. There are 14–18 species in the Corylus genus but many of the European cultivars we have nowadays are Corylus avellana, Corylus maxima or the result of hybrids between these two species. This post we will focus solely on these popular nut producing species.

The leafy bracts that envelope the nuts are the easiest way of telling the species apart. |
During this post, we'll take a close look at these versatile plants, including how and where to grow them, growing them in polycultures, how they can be used in agroforestry systems, coppicing hazel, and we'll look at some of my favorite hardy productive and disease-resistant cultivars that we are offering from our Bionursery.

Overview
Latin name - Corylus avellana, Corylus maxima
Common name - Hazel, Hazelnut, Cobnut, Filbert, Spanish Nut, Pontic Nut, Lombardy Nut.
Common name - Hazel, Hazelnut, Cobnut, Filbert, Spanish Nut, Pontic Nut, Lombardy Nut.
Family- Betulaceae
History - Pollen counts reveal that Corylus avellana was the first of the temperate deciduous forest trees to immigrate, establish itself and then become abundant in the post-glacial period. Humans have been enjoying hazels since prehistoric times and it is thought by some that hazelnuts provided a staple source of food before the days of wheat. Evidence of large-scale Mesolithic nut processing, some 9,000 years old, was found in Scotland and Hazels have been used extensively across the temperate zone throughout all civilizations.

Corylus avellana - Common Hazel |
Description - Corylus avellana - Grows as a small tree or large shrub commonly reaching heights of 5 m with a 5 m spread, but sometimes can reach twice that height and takes a tree-like form. The leaves, that open in late April and May and fall in November, are almost circular with double toothed edges and a short pointed tip. The leafy bracts are shorter than the nut.
Description - Corylus maxima - Grows as a large shrub 6 m high with a 5 m spread. Resembling C.avellana but with young grey twigs, glandular and bristly leaves that are wider, longer catkins and leafy bracts that are tubular and closed twice the length of the nut. The nuts are also longer than C. avellana
Both species are monoecious. The male flowers are encased in catkins that brighten up the landscape in the winter. The female flowers are tiny red tassels that emerge from buds on the stems.
Sexual Reproduction - As mentioned above the plants are monoecious, producing male and female flowers on the same plant. The male flowers are held in catkins that form during the previous summer and open in the dead of winter and flower through to early spring. There are around 240 male flowers in each catkin and these produce the pollen. Give the catkins a flick in late February to see a small cloud of pollen erupt. Contrary to the wonderful spectacle of the male flowers, female flowers are almost invisible unless you are actively looking for them. They are tiny individual flowers, visible only as red styles protruding from a green bud-like structure on the same branches as the male flowers.
A wind-pollinated plant, the pollen from the catkins blows to reach the female flowers. If successfully pollinated and fertilized the female flower will grow to become 1- 4 nuts C. avellana or 1 - 6 nuts C.maxima.
Growing Range - Corylus avellana is native to western Asia, North Africa and most of Europe, from the British Isles eastwards to Russia and the Caucasus, and from central Scandinavia southwards to Turkey. Corylus avellana is native to the Balkans and Asia Minor but is widely naturalized elsewhere.
Both species are pioneer plants found in a range of habitats. As a component of ancient forests, they prefer moist lowland soil and are often found growing in the shade of deciduous trees, especially oak. They can be found in hedges, meadows, and pastures, on the banks of streams, waste places, abandoned plantings, the edges of woods, on steep slopes and by paths and roadsides. Hazel grows naturally up to altitudes of 700 m
Hazelnut-producing regions of the world are all close to large bodies of water, which moderate the climate. About 70% of the world’s hazelnut production comes from the black sea region of northern Turkey. Italy produces about 20% of world production. Spain, France, Georgia, Azerbaijan, and the United States produce most of the rest.
Hardiness USDA - Corylus avellana – Zone 4-8
Corylus maxima – Zone 5-8
Ecology - Hazel flowers are an important source of pollen for bees and other pollinators. The pollen-bearing catkins can be available to pollinators from as early as late January - late March. Hazel leaves are used as food plants by the larvae of various species of Lepidoptera. The nuts are used by dormice to fatten up for hibernation and in spring the leaves are a good source of food for caterpillars, which dormice also eat. Hazelnuts are also eaten by woodpeckers, nuthatches, tits, wood pigeons, jays and a number of small mammals.
Where to Plant
Climatic limitations - Both species crop best in areas with cool, moist summers and mild cool winters or in maritime climates. Areas with high summer temperatures are not ideal although good cultivar selection can improve results. Areas with extreme winter cold can also be problematic. The shoots of the plants are hardy to -29 C (-20 F) although winter temperatures below -10 C (-13 F) during the flowering period may damage the male flowers reducing the likelihood of fruit set that year.
The plants will not grow well in tropical climates and require a winter chilling period of 800 - 1200 hrs below 7 C (45 F) which is similar to apples.
Soil - Hazel tolerates a wide variety of soils from calcareous to acid, loam to clay and prefers soil that's well-drained and fairly low in nutrients; overly rich soil gives plenty of leaf growth at the expense of flowers and nuts. Hazels will not grow well in waterlogged and peaty soils. Shallow soils will restrict the growth and height of hazel.
Location - If growing for nut production in cold climates you should avoid planting in frost pockets, and in hot climates avoid windy sites. Hazelnut trees also cannot tolerate excessive heat or a long dry season. A sheltered area with a reliable source of irrigation is essential in hot climates.
Pollination - Hazels are wind-pollinated. As mentioned above cold weather (-10 C and under) during the flowering time can destroy flowers and reduce fruit set. Heavy rain during the time where pollen is being released can also suppress the amount of pollen carried in the air and moist conditions destroy pollen viability.
The plants are in theory self-fertile meaning the pollen from the male flowers can pollinate and fertilize the female flowers on the same plant. However, the blossoming times of the male and female flowers on the same plant do not always coincide and for this reason, it is recommended to plant 2 or more different cultivars to increase the likelihood of pollination occurring. Wild-growing hazel nearby will serve as good pollinating agents for most cultivars and there are many cultivars that work well together to ensure fuller cropping. There are some cultivars that absolutely require pollinating partners so research your cultivars well A good rule of thumb for how many pollinator plants you need to support your main cropping cultivar is 1 to 18. On sites where wet weather is common during the flowering period, this can be increased. The pollinating partner should be a maximum of 45 m away and upwind from the main cropping plants.
Pollen is released from the male flowers in bursts across a 4- 6 week period in January - March. Interestingly, the pollen germinates as soon as it reaches a receptive flower but the fertilization process does not take place for another 4-5 months in June. Once fertilized the female flowers develop into nuts very rapidly with 90% growth occurring within 4 - 6 weeks.
Fertility, Irrigation, and Care
Fertility - On good soils, hazel will not need fertilizers. On poor soils, planting out with 30 L of compost (applied to the surface) and mulching well with straw and repeating this each spring for 4- 5 years will provide a good boost to growth. Planting nitrogen fixing companions can also be very effective.
Irrigation - In cooler climates such as the UK irrigation is not necessary. In warmer climes with hot summers and long periods without rain, applying 30 L of water per tree every 3-4 weeks without rain and mulching well is very effective.
Weeding - Mulching plants with a 10 -20 cm deep mulch each spring and pulling weeds that start to grow through in the summer is good practice especially when the plants are young.
Pruning - When planting out single stemmed whips it's good practice to prune the top down to 45 cm to encourage lower branching (a practice known as formative pruning). Hazel plants often sucker (send up many shoots from the base of the plant. Suckering growth should be removed to keep the stems clear and the crown less congested. Beyond formative pruning and removing suckers we don't prune our Hazels but there is a tradition, as with most fruit trees, to prune in order to achieve an open centered goblet shaped bush.

A classic pruning example practiced in commercial hazel orchards |
If you are going to prune than it's important to know that female flowers (that will form the nuts) are produced from buds on growth from the previous season's growth. For optimal nut production, you should aim to have plenty of previous years stems at least 15-25 cm long.
I read an interesting comment regarding a traditional pruning method used to increase nut production called 'brutting'. This involves prompting more of the trees' energy to go into flower bud production, by snapping, but not breaking off, the tips of the new year shoots' six or seven leaf groups from the join with the trunk or branch, at the end of the growing season. I'll be trying this on a few of our plants this year.
Harvesting - The nuts are fully ripe when the husks begin to yellow and can be picked by hand. Nuts will naturally drop over a 4-6 week period. It's important to not pick before they are ripe as they will shrivel and do not keep well.

Layering and Stooling |
Propagation - We have grown hundreds of hazels from locally gathered seed and this is a very easy and reliable method to propagate these plants. Most of our seedling stock we use for coppice plants and hedging plants. For nut production, we use cultivars as they generally fruit within the 3rd and 4th year after planting and you know what kind of nut you will end up with.
Seedlings can take up to 6 or 7 years to produce nuts and you never know what they will be like. Saying that we have some great nut producing seedlings that we propagated from local plants. They appear to be more resistant to the winter cold and have been providing a reliable crop each year even after bitter cold late winters.
Another great way to propagate hazel, including cultivars that are grown on their own roots, is by stooling and layering. Stooling involves heaping soil at the base of the plant, leaving it for 12 months and then dividing the rooted stems. Layering is burying the stems in the soil for 12 months and cutting them off the main plant once the stem has rooted. Hazels that are grafted onto their own roots will send up suckers. The suckers can be dug out in the winter and planted on. The suckers can be a nuisance and will need cutting back to promote better production. Corylus colurna - Turkish hazel is often used as a rootstock as these are non-suckering and have a deeper rooting habit. Cultivars on Corylus colurna rootstocks are often very vigorous.
Potential Problems
Excessive Heat: Hazelnut trees cannot tolerate excessive heat or a long dry season. They are especially sensitive to drying in windy conditions.
Cold injury: Although a very hardy plant, when growing for nut production the trees are vulnerable during the flowering period in early - late winter. Temperatures below -10 C (-13 F) during the flowering period will damage the male flowers and destroy the pollen reducing the likelihood of fruit set that year. Because not all catkins elongate at the same time, crop damage usually is minimal if there is only a brief cold spell.
Insect/Pest: Grey squirrels are a major pest of hazels. Nut weevils - Balaninus nucum can destroy the maturing nuts. Beetles lay eggs in the immature nuts. The eggs hatch into maggots that eat the maturing nut and bore out of the shell to pupate in the soil where they overwinter before hatching, mating and laying more eggs in the next crop. Clearing up the fallen nuts is a good way to control this pest. Running chicken under the hazels in September can also disturb the pupae in the soil.

Nut Weevils - Balaninus nucum Photo from - https://www.flickr.com/photos/eric-dutoit/5956692789 |
Disease: In the US this species is affected by Eastern Filbert Blight (EFB), which is caused by the fungus Anisogramma anomola and is fatal to trees. However, EFB can be controlled by a variety of management strategies and does not present a major threat to the species as a whole.
Bacterial Blight - Xanthomonas campestris pv. corylina causes leaf spotting, dieback of branches and in worst cases death. Trees under stress are most susceptible.
Suckering - Hazels can sucker profusely and the suckers need to be cut back to allow an open crown and avoid congestion. There are cultivars that do not sucker, generally those grown on the Corylus colurna rootstocks.
Allergies: The pollen of hazel species are often the cause of allergies in late winter or early spring.

Hazel Uses
Wood - Hazel is almost as well known for coppicing as it is for its nuts. The poles from coppice (known as 'wands') are long and flexible and have traditionally been used for wattle fencing, thatching spars, walking sticks, fishing rods, basketry, pea and bean sticks and firewood. The wood is soft and easy to split but not very durable (See Hazel Coppice below).
![]() |
Adding value to the coppice material |
Oil - The nut oil is used as edible oil and contains 65% of a non-drying oil that can be used in paints, cosmetics, etc.
Animal Fodder - The twigs can be used to feed rabbits and goats all year around and the leaves are very palatable to cattle.
Leaves - Leaves contain on average 2.2% N. 0.7% K and 0.12% P and when applied as mulch make a great fertilizer. The plant has the potential to be grown as a chop and drop component in a polyculture system.
Hedging - Hazel makes a great hedge taking well to trimming and providing a dense screen. Nut production is not as high as when grown as free-standing plants but some nuts can be harvested from the hedge. The plants are also tolerant of wind and a 2 or 3-row windbreak can be set up where alternate rows are coppiced on a 7-year cycle.
Bee Fodder - Hazel is an excellent source of early forage for bees providing a source of pollen from February through to March. We include hazel in our Early Polleniser Polyculture, a polyculture dedicated to providing an early source of pollen/nectar to a wide diversity of pollinating insects. By the way you can now buy this entire polyculture (and others) from our online store here.

Medicinal uses - The leaves are used in allopathy: their effect is to stimulate circulation and bile production, and they are used for liver and gall disorders. Hazelnuts are rich in protein, monounsaturated fat, vitamin E, manganese, and numerous other essential nutrients.
Other uses - The finely ground seeds are used as an ingredient of face masks in cosmetics.
Hazelnut Yields
Hazelnut trees can produce a few nuts when they are 2 or 3 years old, but they are not considered commercially productive until 4 years of age and reach peak production from years 10 - 15. Mature orchards can produce 1 -3 metric tons per ha. An orchard can remain productive for about 40–50 years if managed well and kept free of disease.
Yield per mature tree | Yield per acre 4050 m2 | Yield per Ha 10000 m2 | |
Average Production | 3-5 kg | 880-1760 lbs | 1-2 tonnes |
Max Production | 11 kg | 2640 lbs | 3 tonnes |

Example of Coppice - http://www.greenwaytreecare.co.uk/images/Coppicing2.jpg |
Hazel Coppice
Hazel coppice has been practiced extensively in the past and still provides an excellent source of valuable wood especially if you are adding value with wood crafting.
Contrary to what you may expect, coppicing the hazel can extend the life of the plant considerably with some well-managed coppices being centuries old.
Hazel can be grown on various coppice cycles for a supply of poles ('Wands') that are used for a variety of purposes as listed above. A 7 - 10-year rotation is often practiced and is planted out at a rate of 1500 - 2000 plants per ha (spacing is 2.2 - 2.6 m between plants).
In the 7th - 10th year the shoots should be 4-5m long and can be cut at any point during the year apart from August but is usually carried out in the winter. If you cut the coppice in the summer, leaves from the wood make an excellent cattle feed or mulch. Regrowth will quickly reestablish and is vulnerable to browsing from wild and domestic animals. After the first few coppice cycles, regrowth will be fast but after 15 years it will decline. If a hazel coppice is not well managed i.e cut at regular intervals for 40+ years it will die back.
How much wood can be harvested? - A site with 1500 plants per ha can yield 20 tonnes of dry wood or 40 m3 of wood per ha per cycle.
Hazel coppices are often combined with standard trees to make a two-story forest. Sweet Chestnut is a classic combination in the South of England. Oak is also very commonly grown with hazel at a rate of 30 - 100 standard trees per Ha. Too many standard trees will shade out the hazel.

Hazel Polycultures
Hazels are excellent plants for use in polycultures. They are tolerant of shade so suitable in the understorey, are not very nutrient demanding or competitive and are relatively compact and easy to manage. They tolerate pruning very well and can be used for chop and drop plants grown between fruit trees or in hedgerows. If nut production is sought after they should be given a prime position but can still accommodate a range of productive and useful plants around them.
We have used hazel in various polycultures including living hedges, main crop contour plantings, and habitat polycultures.
Here's an example of a design with hazel planted in a polyculture hedge.
We'll be planting out Hazel in our new trial garden - Ataraxia, where we are growing it along with asparagus, currants, wild garlic and various bulbs in 1.5 m wide beds.

Here's a shortlist of ground cover and bulbous plants that we observe growing well with hazel.

Agroforestry Potential Of Hazels
There is great potential for hazels in agroforestry systems. Traditionally, in Europe, hazels were grown in a silvopasture system with sheep grazing the pasture beneath the trees, this has an added benefit of controlling suckering growth. Hazel has also been grown with vines and in Kentish orchards, gooseberries and currants were traditionally interplanted with young hazel.
I've included hazel in a few agroforestry designs the most recent being a 30 ha pastured poultry system where we're using hazel amongst mulberry planted on contour.
Being shade-tolerant the trees are good candidates for use in an understorey. In deep shade, the plants will not produce a significant yield of nuts but they can be used for coppicing or mulch production. In partial shade, they can still produce good yields.

Hazelnut cultivars - Hardy and Resistant to Major Pests and Diseases
There are hundreds of hazel cultivars throughout the world, not to mention the hybrids, American and Chinese species or the Trazels, Filazels, and Hazelberts (perhaps a topic for another post).
Most cultivars belong to Corylus maxima but there are many Corylus avellana and many grafted onto Corylus colurna rootstock. When selecting cultivars for your garden there a few things to consider.
- flowering times - to avoid cold damage in the winter choose a late-flowering cultivar
- suckering behavior - to avoid pruning work or perhaps if growing for mulch or biomass this could be desirable
- size and vigor - to select the right size plant for your garden
- pollinator partners - to facilitate larger and more reliable yields
Below you can find profiles of some excellent cultivars that we have on offer at our Bionursery.
We are currently offering cultivars at €5.3 per tree with a 10% discount for orders over 20 trees. We also have 2nd year Hazel seedlings for hedgerows, biomass, pollinating partners, etc for €4.5 per plant.

In Jilin, China, hazelnuts are an important cash crop. Grown in the mountains well above 700 m, they tolerate winter temperatures to -35C. I'm not sure which variety, though....
ReplyDeletegreat info , tx
DeleteI found this very interesting and educational im am moving soon to a zone that ican grow this in i currently live in central Florida i don't believe it would do well or grow at all. Thank you for the info love continuing my education.
ReplyDeletethank you, good luck with your move and hazel growing :)
DeleteGrowing 5 varieties of C. avellana as a hedge at 1000m in the Blue Mountains west of Sydney. Cool winters
ReplyDelete-2 degrees the coldest; hot summers with frequent mists. 800 mls rain annually but I irrigate if a dry spell. A few nuts last year, Ennis is the best. No disease problems. Overcrowding of the 6 plants probably reduces sunlight access, and I am working out how to prune to allow each one more space. I practiced brutting the last 2 years (late December, southern hemisphere), catkins already forming. Hope more nuts this year, they are so beautiful. Thank you for your detailed article.
Thanks for sharing your experience.
ReplyDeleteI was wondering if a red Majestic contorted Hazel would be a good pollinating partner for an American Hazel. I live in zone 6
ReplyDeleteInteresting that it is also a bee fodder. I have never realized that bees were foraging on wind pollinated plats as well, but now it makes much more sense that salix trees seem to be alive with all the bumble bees in early spring!
ReplyDeleteI just ordered a Red Dragon Contorted Hazelnut (Corylus avellana cv. 'Red Dragon') What other variety of hazelnut can I plant with it as a co-pollinator that stays relatively small?
ReplyDeleteHi Therese. I'm not familiar with Corylus avellana cv. 'Red Dragon' but Ata baba has a long flowering period and stays relatively small.
ReplyDeleteI'm in the mountains of Central Portugal with an evolving food forest in a northeast-facing valley and have C. avellana planted in several locations, some predating my arrival 13 years ago and some I planted. Apples do well here so my assessment of the microbiome was that I ought to be able to grow hazels successfully, even though summers can be hot. Unfortunately the plants are just sold as "hazel" with no cultivar identification. Not one has ever produced any nuts. I'm guessing this is likely to be a pollination problem, but not sure how I can rectify it with no possibility of identifying different cultivars from local suppliers. Do you have any suggestions? Do you ship outside Bulgaria?
ReplyDeleteHi, do the hazels produce catkins in the autumn that are apparent on the trees during Winter?
DeleteYes we ship to Portugal and all over Europe.
Your comment is interesting: I'm also established (in a way) in the mountainous area of central Portugal (S. da Estrela) and I also have an old hazelnut hedge, whose variety I'm also unaware of (they've been there for over 20 years). Mine, however, bear fruit, although they are not cared for. I can, if you like, give you some seedlings ('forks' as they say here) to see if they pollinate your hazelnut trees. And I would be interested as well in the website author's answer to your question about the possibility of importing some varieties from Bulgaria. Let's wait to see the author's response. Good luck!
ReplyDeleteJoão Miranda
Could be that hazel's Quinta do Vale are describing are coppice regrowth that has not reached sexual maturity yet.
DeleteYes we ship to Portugal and all over Europe.
