Here in zone 7a, our Montauk daisies (also known as Nippon daisy) tend to get pretty leggy by mid-June.  If left untrimmed we would still get a pretty, but sparse, flush of blooms in early fall.  Although some people prune them by mowing the plants down, but we prefer to prune them by hand so that we can root up the cuttings.

When To Prune Montauk Daisy

Montauk daisies can be pruned both in the early spring and again in late summer.  We prefer to prune them once in late June, which gives them 2 months to fill out before the September bloom.  This also allows the rooted cuttings to get established in the soil before the onset of winter.

The plant will begin to develop new shoots within a week or so after pruning.

How Much To Prune

Trim Montauk daisy down to approximately 12 inches.  Older stems tend to get woody, and leaving a portion of the woody stem unpruned will provide a strong supportive base for the new plant shoots.

How To Propagate and Root Montauk Daisy Cuttings

Montauk Nippon Daisy Cutting Propagation

After you have pruned your plants, trim your cuttings back to about 8 to 10 inches.  Strip off all the lower leaves, leaving about 5 to 7 of the top leaves intact.

You can plant your cuttings in a sandy soil mixture, but because we have so many cuttings we just set them in a container of water.

Montauk Nippon Daisy Cuttings Propagation In Water

Keep your daisy cuttings in a cool location and out of direct sunlight until they begin rooting.  We keep our cuttings indoors on a counter under a window that provides filtered sunlight.

Change the water every couple of days. It takes 3 to 5 days for the stems of the daisy cuttings to callus, after which it will begin the process of developing roots.
