It’s time to prune deciduous, ornamental grasses such as this one:
Calamagrostis acutiflora Karl Foerster (feather reed grass)
This is one of my favourites because of it’s tall, slim shape ( think of it as a bit of a supermodel), it’s useful in many different types of gardens so long as it has a sunny position in well drained soil.
Simply cut back the old growth to reveal the new, fresh green shoots which will eventually grow to about 1.5 metres ( 5 feet) high in the spring and early summer. It will only spread to about 50 cm ( 20 inches ) across, making it perfect for small areas where some height is needed. It looks a bit self-conscious on it’s own, so plant in groups of 3, 5 or 7 depending on the size of your garden.
It produces fine seed-heads towards the end of the summer and the whole plant turns a straw-blonde colour, giving a soft, billowy presence to the border.
Leave the foliage in place during the winter, cut back in February and off it goes again … simple.
