![]() After a year, the suckers should have rooted into this while attached to the mother tree. Heap good soil around the base of the young stems in early summer. Plants are prepared by cutting them down to promote lots of new stems, but if there are a number of young suckers, this may not be necessary. However, cultivars will not come true from seed and are usually propagated by layering. ![]() Plant 1in (2.5cm) deep into pots of good seed compost (there is plenty available on Amazon (opens in new tab)) in fall and place in a cold, airy and covered place where they will not get too wet. The simplest and cheapest method of introducing hazelnuts to your plot is by sowing seeds, preferably from local trees acclimatized to their surroundings.

During the first couple of years, cut leading shoots by half to develop a dense framework. In winter, shorten long stems by half and remove suckers, holding in mind the intended shape of an open-centered plant with around five well-placed leaders. During summer, remove unwanted lower laterals and shorten the rest by a third. To grow trees on a short stem, prune the leader to 18-36in (45-90cm) in the winter after planting. Regularly coppiced plants provide good, straight stems perfect as climbing plant supports, especially for pole beans. Light floods into their space and new growth soon appears. This means taking a saw to overgrown plants while they are dormant and cutting all the stems almost to ground level – within 5-7.5cm (2-2½in) from the ground, says the RHS (opens in new tab). Once every five to ten years or so, you can coppice the entire tree. This process can encourage nut production. 'Allow the younger thinner stems to remain,' they add. Once your hazel is five years old, the Nature Hills Nursery (opens in new tab) website recommends regular renewal pruning by removing a third of the oldest, fattest stems right down to the ground every three to four years. We like the look of this Corona model, available on Amazon (opens in new tab). Most gardeners reduce the number of stems by thinning them down to around eight branches from mid-winter to early spring using loppers and a folding pruning hand saw. Leaving hazels to develop a multi-stemmed thicket is an option, but they respond well to pruning.

In our large garden, we have a small ‘wilderness’ where trees have been left to regenerate naturally and shade out brambles. Many plots now have a corner that has been rewilded, where a regularly coppiced hazel will yield plenty of plant supports. The European hazel is similarly useful in UK gardens, where they don’t suffer from major pests or diseases. The dappled shade cast by their leaves will suit a ground cover of woodland plants and spring bulbs. ![]() If you have the space, plant a nuttery with several hazels set at least 12ft (3.6m) apart and pruned for shapeliness. With its wavy-margined, heart-shaped leaves turning yellow, orange and burgundy in fall spring show of catkins and frilly nut cases, the American native hazelnut suits wildlife-friendly gardens and makes an excellent hedging plant.
