Bedding plants like verbenas root easily from cuttings. They can be placed in a tray on the windowsill with a clear polythene bag as a cover or kept in a propagator in the greenhouse. These cuttings are known as softwood cuttings, as they’re taken from the soft new growth at the tips of shoots.
Softwood cuttings develop roots quickly and easily so it’s well worth taking some to make more of your favourite plants. Once they’ve formed a good flush of roots at the base, simply pot them into individual pots to grow on and use as free bedding plants the following year.
