About this plant
This makes a medium sized tree. It is quite slow growing and is bell-shaped for many years. Eventually it develops a very broad and rounded shape. It has shiny, oblong, dark green leaves that have yellow autumnal tints. The highlight of the tree's season is spring when it produces masses of long, slender, yellow catkins that dangle from its bare branches. In summer it bears fruits that are held in pendulous bunches, looking like the fruits of the hop (Humulus lupulus) and this gives rise to its popular name 'Hop Hornbeam'.

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-Autumn · Planting
Prune to maintain young trees
While it is still possible to safely reach up and into the tree, remove dead or damaged foliage, and crossing or misplaced branches in early spring while the plant is still dormant.
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.
