When to prune beech trees?
- Botanical name
- Fagus sylvatica
- Family
- Fagaceae
Beech trees are pruned from July to August. They are planted from October to February.
Beech trees are woody perennials. The edible parts are the leaves and seeds.
A cut in the second half of summer leaves the beech one last flush of leaves, and those stay on dried until spring, so the hedge screens the view in winter as well. The first cut comes in the third year, then one every year. The hedge is kept wider at the base than at the top, so that light reaches the lower branches too.
Beech plants for a hedge are set out bare rooted while the plant is dormant. Planting waits as long as the ground is waterlogged. A beech on its own grows into a forest tree and needs far more room than a plant in a hedge.
Beech seed is edible only after cooking. Raw or unripe mast contains trimethylamine and oxalic acid and causes vomiting and stomach pain, and it is dangerous above all to children and dogs. Cooking is a condition for the young leaves as well.

Pests and diseases
Listed here is every problem for which the sources name this plant as a host. The problems are not listed in order of how common they are.
- Signs
- The plant dies suddenly, often in mid season and without any decline beforehand. Peel the bark at ground level and under it there is a white or cream sheet of fungal tissue, thin as the skin of a mushroom. In the soil there are black or brown strands like bootlaces. In late summer and autumn tufts of honey brown mushrooms with a whitish ring on the stalk appear by the stumps or over dead roots.
- Prevention
- The fungus spreads through the soil with its strands, from a few centimetres to a good hand's width below the surface, and infects the roots of a living plant when it touches them. So do not leave stumps and dead roots in the ground. No plant is completely resistant, but privet, lilac, viburnum, weigela, forsythia, butterfly bush, rhododendron, thuja and walnut are particularly susceptible.
- What to do
- There are no products. The only thing that works is digging out and removing every infected root and stump, which takes away the food without which the strands in the soil do not grow. A vertical barrier of rubber or thick plastic sheet, buried about half a metre deep and standing a few centimetres above ground, stops the spread into an unaffected part of the garden.
