Corylus avellana 'Contorta'
- Position: full sun or partial shade
- Soil: fertile, well-drained, preferably chalky soil
- Rate of growth: slow-growing
- Flowering period: February to March
- Hardiness: fully hardy
In February and March, the bizarrely contorted stems of this small hazel are draped with golden-yellow catkins. The leaves, which are mid-green and twisted, appear later. This corkscrew hazel is ideal for the middle of a sunny border, where its winter outline can be fully appreciated, or planted in large containers. The twisted stems, much-valued by flower-arrangers, also provide a curious and unusual focal point for an oriental-style garden.
- Garden care: Cut out dead, diseased and damaged wood in March and apply a 5-7cm (2-3in) mulch of well-rotted organic matter around the base of the plant.

Q:What is the root spread of this plant. The soil is rather heavy but fertileAsked on 17/5/2015 by Bee walk from Deeping St James Lincs
Root systems tend to be more compact in heavier soils, however as a very general rule, the root system of a plant will roughly mirror the size of the top growth.Answered on 29/5/2015 by Helen from crocus
Q:how to treat whitefly on contorta avellanaAsked on 13/7/2014 by magnolia from n ireland
Aphids are a common pest but they can be treated in several ways.
The organic path is trying to encourage natural predators into your garden, -ladybirds, lacewings and hoverflies. We sell various ladybird and lacewing 'homes' to try and encourage them into your garden.
Then there is the biological control, where you can buy the live ladybirds or lacewing larvae to eat the aphids. I have attached a link below to this.
Or alternatively it is the chemical route which is spraying with a suitable contact or systemic insecticide.

Q:Hi what size of pot should i plant my hazel contorta in pleaseAsked on 14/11/2013 by wendy from west lothian
These are not the fastest growers, but they do get reasonably big over time. With this in mind, you have two options. You can either pot it up in stages every couple of years (a 30cm pot would be a good starting point), or you can pot it straight into its permanent home, which should be at least 60 x 60cm.Answered on 15/11/2013 by Helen from Crocus
Q:Plant advice for 2 new beds please
Hello, I need some help to decide which plants to put into two new areas please:- 1: A semi-circle flash bed at the front of the house, size approx 2m x 0.80m and 0.80m deep. I thought about the 3 following options for a small tree/bush in the middle:- a) Magnolia soulangeana, but I was worried about the size that it could grow to and possible problems with roots etc . Will it stay small if the size of the container is used to restrict it? b) Witch Hazel (Hamamelis intermediana 'Diane'). Will it spread too much? I think this is very pretty. c) Corylus avellana 'contorta' Then I also need to think about ground cover plants to help suppress weeds. I am only interested in fully hardy, easy to look after plants, could be with some flowers or coloured leaves. 2:- A thin path between neighbours (approx 2m x 0.40). My idea is to plant bamboo. I would love a modern thin run of bamboo with ground cover. My worry is which bamboos to use. I love the yellow, like Phyllostychys aureocaulis (Golden Grove) but not sure if it is strong enough as it could be exposed to some wind. I bought from you a couple of years ago the Phyllostychys aureosulcata 'Spectabilis' which I planted in pots but it died this year. I see on your website some other bamboos but I don't like them as much as their canes seems less exposed and have a lot more foliage. But possibly these would be a better alternative... ...? For the ground cover I as thinking of Ophiopogen nigrescen. Do you think these plants will be suitable, or have you any other suggestions? Thank you for your help, GaliaAsked on 15/2/2010 by e moran
A:Hello Galia, All of the taller shrubs you mentioned for the semi-circular bed will get quite large, but their growth will be restricted (both in height and spread) if they are kept in a pot where their roots are restricted. For groundcover you could opt for any of the following:- Bergenia http://www.crocus.co.uk/search/_/search.bergenia/ Helleborus http://www.crocus.co.uk/search/_/search.helleborus/ Heuchera http://www.crocus.co.uk/search/_/search.heuchera/ Epimedium http://www.crocus.co.uk/search/_/search.epimedium/ Geranium http://www.crocus.co.uk/search/_/search.geranium/ Erica http://www.crocus.co.uk/search/_/search.erica/ As for the bamboos, even the most well behaved one (Fargesia murieliae) will spread to around 1.5m across so you should keep this in mind when planting it in such a confined space. Perhaps a better option would be one of our hedging plants, which can be cut back hard against the wall. Taxus http://www.crocus.co.uk/plants/_/shrubs/trees/hedging/conifer/bigger-trees/best-in-very-large-gardens-parks/taxus-baccata-/classid.6230/ or Ligustrum http://www.crocus.co.uk/plants/_/shrubs/hedging/ligustrum-ovalifolium-/classid.4093/ would be good options. I hope this helps. Helen Plant DoctorAnswered on 16/2/2010 by Crocus Helpdesk
Q:Winter flowering shrubs and climbers to plant with new hedge
Hello, I have newly planted a hedge (made up from Hornbeam, Rosa rugosa, Blackthorn, Cornus, Hawthorn and Hazel) about 50ft long. I have been told that if I was to plant amongst the hedge some winter flowering Clematis such as 'Wisley Cream' it would give some nice colour these bleak winter months when the hedge is bare of foliage. The hedge is south facing and although the ground is ???good??? heavy Cambridgeshire clay the hedge has been planted in a trench back filled with leaf mulch, chipped wood and spent peat. Although I have said about in-planting Clematis in the hedge, I am open to other plant suggestions if you have any. Regards TerryAsked on 31/12/2009 by Terry Allum
A:Hello Terry, If you click on the following link it will take you to all our winter flowering climbers - of which the Jasminum is tougher and more like a shrub. http://www.crocus.co.uk/plants/_/climbers/plcid.15/vid.204/ Alternatively, this link will take you to all our winter flowering shrubs. http://www.crocus.co.uk/plants/_/shrubs/plcid.1/vid.204/ I hope this helps.

Q:How do I prune my contorted hazel?
We inherited a contorted hazelnut tree from the previous owners of our house. While it is beautiful, its growing pretty rapidly and there's no light underneath. Can you give me some pruning tips please?Asked on 30/8/2005 by Vicky Navagh
A:If you want to re-vamp your hazel, then you can cut back all the stems to within 2 or 3 buds from the base in early spring. Alternatively, if you dont want to take such drastic action, you can cut back some stems to relieve congestion and leave some remaining, and then remove any lower branches that are creating a tangle back to the main trunk. This should also be tackled in early spring.Answered on 31/8/2005 by Crocus
The garden is at its most dormant right now, so it’s a good time to catch up on any pruning missed or forgotten since the autumn. If the weather isn’t favourable, you can leave it for a week or two, but make sure all winter pruning is completed before theRead full article
