How to Clone Phlox


Phlox is a herbaceous perennial flowering plant that thrives in sun to partial shade. Tall garden phlox will grow 2 to 3 feet in height and bloom in fragrant, many-hued flowers. If you are looking for plants for a butterfly garden, consider phlox because it is a host plant for several types of butterflies. Hummingbirds flock to the plant as well. Phlox is hardy to USDA zones 3 to 9. Take cuttings from new growth in the spring to clone phlox.

Step 1

Cut a 4- to 6-inch piece from the tip of a phlox stem. Remove all but the top two leaves from the stem.

Step 2

Add equal parts of perlite and sand, combined and moistened, to the nursery pot. Use your finger to create a hole in the soil for the cutting.

Step 3

Insert the cut end of the stem into the rooting hormone, and stick the cutting into the planting hole, packing the planting medium around it. Make sure that at least one leaf node (the bump on the stem where a leaf joined it) is buried.

Step 4

Place the potted cutting in the plastic bag and seal it. Leave the cutting in a well-lit area, out of direct sunlight, until the cutting roots. This should occur within six to eight weeks. Remove the pot from the bag when the plant has rooted.
