How to Transplant a Crocosmia


Crocosmia have long leaves and produce beautiful flowers in red, orange, or yellow. Hummingbirds love crocosmia blossoms, but few garden pests do, making this an easy plant to grow. Crocosmia generally blooms late in the season, adding a bright touch of color to a garden which may have started to fade as the growing season is winding down. Crocosmias grow well in U.S. Department of Agriculture hardiness zones 6 through 10, though they should have mulch to protect them during the winter in zones 6 and 7. Crocosmia should be transplanted in early spring, after the danger of frost is passed but before new growth begins.

Step 1

Use a spade or sharp trowel to divide an existing crocosmia. Dig straight down approximately 6 inches through a portion of an existing plant and then shove your spade or trowel under the portion you wish to move and gently lift up, taking as much of the roots and the bulbs (technically corms) with the plant as possible.

Step 2

Place the piece of crocosmia that you have dug up into a pail and cover with a damp newspaper.

Step 3

Choose an area that receives at least four hours of sun during the day, especially in the afternoon, and is well drained to receive the crocosmia transplants.

Step 4

Spread 2 inches of organic manure over the area to receive the crocosmia. Work the manure into the soil at least 6 inches deep, loosening the soil and breaking up dirt clods. Rake the area smooth, then use your trowel to dig holes 6 inches deep and slightly wider than the root ball of the crocosmia. Place your crocosmia into the hole and gently press your soil mixture around it, planting your crocosmia the same depth as it was originally growing.

Step 5

Water well, making the soil damp but not soggy. Keep the soil damp but not soggy until you see signs of new growth. This should only take a week to 10 days, as crocosmia take well to transplanting. Water as needed once established.
