Dusty Miller

This plant should not be over watered; only when the top layer of soil feels completely dry should it be watered. When watering Dusty Miller, do not saturate the ground. Allow the excess water to drain away and avoid setting the pot in a dish that catches dripping water. One of the most common causes of death in Dusty Miller is root rot, so it should not be planted in areas where the soil is very moist for extended periods of time.

Dusty Miller does best in full sun to partial shade, meaning four to six hours of direct light is preferred. When grown indoors, it should be placed in front of a sheer curtain in a well-lit area to allow the most amount of sunlight possible. If grown outdoors in a mostly shaded area, it will be more susceptible to diseases due to dampness and will require more frequent watering.

Dusty Miller is very tolerant of both heat and cold, although it prefers temperatures above 50 degrees Fahrenheit (10 Celsius). In cooler climates, it can be sensitive to cold, dry air and should be protected from drafts. When temperatures reach below 40 degrees Fahrenheit (4.4 Celsius), it should be brought indoors in a container.

Dusty Miller prefers dry humidity and is susceptible to dampness that can damage the foliage. To reduce the chance of fungal diseases, it should be kept at 45 to 65% humidity day and night. It should never be misted or placed in a heated room.

Dusty Miller prefers well-draining, light soils with a slightly acidic pH of 5.5-7. Soils that are too heavy can lead to root rot and should be avoided. As normal, add some organic matter such as peat, compost, or manure to the potting soil to improve its drainage. A soil that is too sandy can easily compact and the plant will suffer.

Dusty Miller does not require frequent fertilization, although it can benefit from it when grown in particularly nutrient-deficient soils. Use a balanced all-purpose fertilizer and dilute it according to the directions on the back of the package. Avoid fertilizer burn, which can cause yellowing and discoloration of the foliage.

Dusty Miller is not often plagued by pests. However, common ones include mealybugs, aphids, and spider mites. Mealybugs can be found sucking the sap from the roots of the plants, while aphids and spider mites are found on the foliage. All three of these pests can be eliminated with a combination of insecticides, regular removal of their eggs, and judicious pruning. Be sure to read and follow directions on the insecticide or pesticide you choose.

Dusty Miller should be repotted when its root system has grown too large for the current pot. It is usually necessary to repot the plant every one to two years, depending on the amount of growth. When repotting, remove the plant from its current container and divide the rootball. Transfer the plant and its rootball into a new container with fresh, well-draining potting soil and replant it. Make sure that the soil is damp before it is placed in the new container.

Dusty Miller should be pruned frequently to keep it neat and healthy. Pruning requires removing dead and dying foliage, as well as trimming the plants to the desired shape. Prune away any areas that appear to be diseased or otherwise unhealthy. Prune frequently to ensure that the plants will remain healthy and compact. If the plants become too large, or are overgrowing, they should be divided and transplanted.

Mulching helps retain moisture around the plant and can provide nutrients to the soil over time. For Dusty Miller, a light mulch of straw or leaf litter is recommended. Keep mulch away from the stems to reduce the chances of rotting.

Dusty Miller can be propagated easily by cuttings in the early spring. Take cuttings from the tips of the plant, making sure to get at least 6 inches of stem. Dip the cuttings in rooting hormone then place in the potting soil. Keep the potting soil moist and in a bright, indirect light. In a few short weeks, the cuttings should have rooted and taken to the soil.

Dusty Miller does not require any additional support or training. Its stems are weak and cannot support the weight of heavy flowers. However, they can be staked and tied loosely if desired.

Dusty Miller does not require any sort of rest period and can be grown year round. It should be kept in a cool, dry place when not actively growing and given adequate light when not planted outside. If indoors, do not place in a heated room.

Dusty Miller is toxic to cats and dogs if ingested. If eaten, it can cause numerous health issues, including vomiting and loss of appetite. To avoid this, keep pets and children away from the plants and make sure to dispose of dead foliage properly.
