About this plant
This extraordinary plant presents a tangled mass of shoots and branches in a bewildering maze, yet produces straight rather than bendy catkins. It is very much a plant that stands alone, much more attractive in its bare branched state in the winter months. When covered in summer foliage the plant is less distinctive, in fact, it's a plant to love or hate. The original plant was discovered in a hedgerow near Gloucester in 1863. Try planting this behind herbaceous plants that are cut to the ground for the winter months, but which can make quite sizeable specimens in the summer garden when the hazel just looks less spectacular.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Spring - early · Planting
Prune annually or for reducing size
The plant can either be generally pruned by removing dead or damaged growth and misplaced or crossing branches. When it becomes too large, or if a smaller plant is required, take the plant back to about 3 buds from its base.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
