Arabis spread by forming carpets, made up of small rosettes. Taking cuttings from these rosettes is a cheap way of propagating plants that grow naturally in this way.
Insert them into good quality multi-purpose compost, with some horticultural grit or perlite added. Use a sharp knife or secateurs to prepare the cuttings as rock plants are prone to fungal infection if bruised. It's also a good time to take cuttings from alpines, such as gentians.
While rock garden plants should never be left standing in water, cuttings can’t be allowed to dry out, so check and water them carefully. Keep the cuttings at around 10°-15°C, out of direct sunlight. Cover to keep in moisture, with a cloche or cold frame lid, but ventilate the plants frequently. Remove any cuttings that are dying back promptly so as not to spread any infection.
