Plant description
A compact and award-winning deciduous hazel or cobnut tree with heart-shaped leaves that transition from dark purple in spring to green in summer and mature to maroon in autumn. 'Rote Zellernuss' bears pink catkins in late winter and early spring that attract early pollinators, and produces round, medium-sized, red to purple filbert nuts in a smooth hard wooden shell, which can be eaten fresh or used in baking and desserts. This superb variety is self-sterile so requires a pollinating partner such as 'Purple Filbert'.

How to care for cobnut Rotblättrige Zellernuss:
When planting cobnut or filbert, improve the soil with well-rotted compost or a soil conditioner and add mycorrhizal fungi to encourage strong root establishment. Support taller young plants with a cane or stake until they are established, and water generously around the base, especially in the first season.
Bare-root plants should be planted out as soon as they arrive. If this is not possible, they can be heeled in temporarily (covering their roots with soil) or potted up. Before planting, soak the rootball in a bucket of water for half an hour and make sure to incorporate lots of well-rotted garden compost in the planting hole.
These trees crop reliably on chalky soils and are best trained as a goblet-shaped bush for good fruiting. Keep a 60cm (2ft) radius around the base clear of weeds or grass, and apply a 5-7cm (2-3in) mulch of well-rotted organic matter each spring to conserve moisture and feed the soil.
Prune in March by removing dead, diseased or damaged wood, and thin out overcrowded stems if needed to maintain the open goblet framework. Light summer pruning can also help check vigorous growth and encourage nut production. For the best harvest, plant more than one cultivar nearby to ensure cross-pollination, as this greatly improves both yield and nut size.
Protect developing nuts from squirrels, who can strip trees before they are ready, by netting individual branches, using tree guards, or harvesting early once the husks begin to loosen.

Please note:
This tree is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.
