What else to prune in those months? September
Southern marsh-orchid: how to prune it?
- Leave the spent spikes until the capsules are brown and open.
- Then mow short and remove the cuttings, to keep the soil poor.
- Mark the plants with a stick so you do not mow them by mistake.
- Pull up young willow, alder and brambles before they start to cast shade.
How much to cut, and how often?
- One pruning period a year: September.
What does it mean for wildlife?
- As a native plant, it feeds more insects than a non-native species.
Caution: Do not mow over the plants in May–August: you would lose that year’s flowers and seed, and the plant could not properly build up its tuber for the following year.
