Water & Humidity

Dusty miller plants prefer well-draining soil that is kept slightly moist but not waterlogged. It's best to water the plant when the top inch of soil feels dry to the touch.

Water deeply, allowing the water to soak through the soil and drain out the bottom of the pot. Avoid getting water on the leaves, as this can encourage fungal diseases.

As for humidity, dusty miller plants don't require high humidity levels and can tolerate dry indoor air. However, if you live in a dry climate, you can mist the plant occasionally to increase humidity levels.

Dusty miller plants are not heavy feeders and can do well without fertilizer. However, if you want to promote healthy growth and vibrant foliage, you can fertilize the plant once a month during the growing season (spring and summer) with a balanced, water-soluble fertilizer.

Be sure to follow the instructions on the fertilizer package and avoid over-fertilizing, as this can damage the plant.

Dusty miller plants don't require frequent repotting and can do well in the same pot for several years. However, if the plant becomes root-bound or the soil is depleted of nutrients, it's time to repot.

It's best to repot the plant in the spring, just before the growing season begins. Choose a pot that is one size larger than the current pot, and fill it with fresh potting soil.

Gently remove the plant from the old pot, loosen the roots, and place it in the new pot. Water the plant well and place it in a spot that receives plenty of light.


Dusty miller plants can be propagated by stem cuttings or by division. Stem cuttings are the easiest and quickest method of propagation.

Simply take a stem cutting that is about 4-6 inches long, remove the bottom leaves, and place the cutting in a pot filled with moist potting soil. Keep the soil moist and place the pot in a spot that receives indirect light. The cutting should root within a few weeks.

Division is another method of propagation that involves separating the plant into smaller sections and repotting them individually. This method is best done in the spring, just before the growing season begins.

Dusty miller plants don't require a lot of pruning, but you can trim them back to encourage bushier growth and prevent them from becoming too leggy.

You can also pinch off any yellow or dead leaves to keep the plant looking tidy. It's best to do any pruning in the spring, before the plant starts to grow actively.

To prune, use a sharp, clean pair of scissors or pruning shears and make clean cuts just above a leaf node.
