You can boost growth and produce more reliable yield by using a rooting hormone. This is optional step, plant do root without any supplement, if provide good condition.

Keep in mind to snip the flowers if they have grown from their cutting, to increase root and leaves development. This is not essential if your plant is already established in the garden.

Varieties 

All varieties of Silver ragworts are best for gardening. Some are very fine, while others are only slightly lobed.

  • Variety like “Cirrus”  has broad leaves with scalloping on the edges.
  • and “Silverado” is the fern-like foliage popular in many gardens.
  • Whereas, “Silver Lace” has very fine foliage, as the name implies.

As I earlier mentioned, this species is not good for growing from seed. It might show unexpected results.

Instead, it is better to find plants at your local nursery or garden center. But if you want to give it a try, I will recommend the Silver dust cultivar.

From division

The ideal time to grow from the division is in the fall season when the dusty miller gets dry. By division, you’re able to grow multiple identical plants of the same cultivar.

This is not true with propagation from seeds. Nowadays most plants are cultivars or hybrids if you try to regrow from their seeds. It will not grow identical to the parent plant.

Here, how to do division or propagation from stem cutting:

  • First, make a spot to plant stem cutting. Rub the soil to make it smooth, where you have decided to grow. 
  • Root out dry dusty miller from the soil, do this with your hand (gardener gloves on the hand).
  • Split the stems and make different stem cuttings. Take a shear and cut the bottom end of the stem cutting. 
  • Cut till a white-colored tissue gets visible. Make these stem-cutting stands in the soil by using your hands.
  • Sprinkle some nitrogen-rich fertilizer on the surface of the soil, this will help stem to grow roots quickly.
  • After some time, spray water on the soil to make it moist.
  • The stem cutting will start rooting in 2 weeks and after a month they get well established.
  • You also grow them in pots by division method.

To avoid root rot, the soil must be drained well. You need to water the plant regularly until its root develops.

  • If you try to transplant from wet soil then roots might get damaged. 
  • The soil gets soggy than water that swole the roots and makes it soft.

The plant blooms in hot and dry conditions, where most of the troublemakers or pests don’t come.

This is why it can be used as a background plant for low-growing, creeping annual plants, such as wave petunias.

Though, if you see the leaves getting wrinkly, curled, stunted in growth, or even abandoning the stems entirely, check for these tiny suckers. A little spray of insecticides should take care of them.
