Propagation of Euthamia graminifolia (L.) Nutt. var. hirtipes (Fern.) C.& J. Taylor
Euthamia graminifolia (L.) Nutt. var. hirtipes (Fern.) C.& J. Taylor, commonly known as hairy goldenrod, is a herbaceous perennial plant that is native to North America. This plant is valued for its beautiful yellow flowers which bloom in the late summer and fall.
Propagation by Seed
The easiest way to propagate Euthamia graminifolia (L.) Nutt. var. hirtipes (Fern.) C.& J. Taylor is by seed. The seeds of this plant can be collected in late summer or fall when they have turned brown. After collection, the seeds can be stored in a dry place until planting time.
To plant the seeds, start by preparing a well-draining seed-starting mix in a tray or pot. Sprinkle the seeds thinly on top of the mix, cover them lightly with more mix, and press them down gently. Water the seeds gently, and maintain moist soil until the seeds germinate in 2-3 weeks. Once the seedlings grow big enough to handle, they can be transplanted into individual pots filled with regular potting soil.
Propagation by Division
Euthamia graminifolia (L.) Nutt. var. hirtipes (Fern.) C.& J. Taylor can also be propagated by division. This method is best done in the spring or early fall when the plant is not in full bloom. To do this, carefully dig up the plant and separate the clumps into smaller sections. Each section should have some roots and several stems.
After division, plant each section in a prepared hole in a well-draining soil mix. You should space the holes 1-2 feet apart to give each plant enough space to grow. Water the newly planted divisions thoroughly and keep the soil evenly moist until new growth appears.
Propagation by Cuttings
Euthamia graminifolia (L.) Nutt. var. hirtipes (Fern.) C.& J. Taylor can also be propagated by stem cuttings during the summer months. Take several 6-inch cuttings from the tip of the plant, and remove the lower leaves from each cutting. Dip each cutting in rooting hormone (optional) and plant it in a pot filled with a well-draining soil mixture. Water the cuttings thoroughly and keep the soil evenly moist until new growth appears.
To encourage root growth and prevent water loss, enclose the pot in a plastic bag. Keep the pot in a warm, bright location, but out of direct sunlight. Check regularly for new growth and remove the plastic bag once new growth appears. Once the cuttings have rooted, they can be transplanted into individual pots filled with regular potting soil.
