This calendar is not divided into four seasons but into ten phases. The hazel has both female and male flowers, with only the male forming the conspicuous catkins.

Plant a hazelnut bush

If you want to plant a hazelnut bush in the garden, you get a very undemanding and uncomplicated plant. The sunnier the location, the richer the nut harvest will be. Hazelnut bushes are so-called external pollinators. That is, at least two bushes should be planted so that the flowers are pollinated and fruits grow. The shrub does not make any special demands on the garden soil, but waterlogging should be avoided. The fast-growing hazelnut is suitable both as a single plant and as a hedge plant. The best time to plant is in autumn.

Hazelnuts ripen from September

Animals like squirrels are happy to have hazelnuts in the garden.

The fruits of the hazelnut ripen from around September. They then turn brown and fall to the ground. After removing the shell, the seeds inside can be eaten.
