How to Propagate Seaside Daisy

This step by step guide with pictures shows how to propagate seaside daisy from plants in your home garden to create mass plantings and save money.

Seaside daisy (Erigeron Karvinskianus) is a perennial spreading ground cover which flowers during most of the year. The dainty white flowers turn to pink over time and make a romantic display under rose bushes, along borders or in pots.

Caring for Seaside Daisy Plants

These daisies are hardy plants which grow in a wide range of conditions from coastal as the name suggests to inland temperate areas. They will tolerate frost and require little water once established.

During warm weather and especially during drought conditions it is a good idea to water your seaside daisies once every few days to keep them looking their best.

An application of either slow release fertilizer or liquid fertilizer will also result in quicker growth.

Apply an inch of mulch after planting to keep down weeds and prevent water loss. Once the daisy grows it will create a thick mass of leaves and flowers which is effective at keeping down weeds naturally.

Seaside daisies will benefit from a prune back during the winter months to keep them looking their best. Fully grown plants can be cut back by ¼ to ½ of the plant.

Propagating Seaside Daisy Plants

There are two ways to propagate seaside daisies. The first is the easiest way which is simply waiting for more plants to germinate under the existing plant. The second way is to take cuttings.

Transplanting New Plants

After one years growth gently lift the edges of the plant then look for new plants which have taken root.

Water the new plants well then use a trowel to lift the plant keeping as much of the soil around the roots as possible. Plant directly in their new position then water well to prevent transplant shock.

  2. Take the Cutting

    Find an older stem on your seaside daisy. They will be tan to brown in color. Cut towards the base of the stem at an angle then cut off the top at an angle so the cutting will be 2 to 4 inches (5 to 10cm) long.

  4. Keep Moist

    Place the pot in a saucer of water which will keep the cutting moist. Once you see new growth, let the pot dry between watering so the roots are not waterlogged.

  5. New Growth Appears

    New growth will appear from the base of the plant with the stem drying off. The seaside daisy can be potted up or planted direct in the garden once you have plenty of new growth.
