After mild wet winters and in heavy soils rich in clay, creeping buttercup spreads widely using runners in the same way as strawberry plants will do at the end of the fruiting season. It is difficult to eradicate from amongst permanent plantings in borders and in the fruit garden.
Dig out all plants complete with root and all runners; do not compost the roots or runners as these will continue to grow and spread in your compost heap. Your bonfire heap is your friend in curing this plant.
If you have buttercups in fruit beds, you need to remove them completely using a trowel.
This weed’s presence often indicates the need for improvements to soil structure and drainage. By digging in compost, well rotted manure and other organic material over the winter you will improve the soil structure which will help to cure the conditions that creeping buttercups so enjoy. Better soil structure may well improve the drainage too.
But it may well take more than one winter to achieve the soil structure improvements. Do not expect instant results – time and patience, more compost, well rotted manure and other organic material will win through though.
