The answer to this question depends on the context. In some cases, silver dust may return every year. For example, if silver dust is produced by certain types of trees, it is possible that it will return every year as the trees naturally shed their leaves.
In addition, if silver dust is produced by particulate emissions such as fires or industrial activities, then it may also recur year after year.
In other cases, silver dust may not return every year. For instance, silver dust that is derived from mining activities may not return year after year if it has already been mined away. Similarly, silver dust that’s produced by natural phenomena like volcanic eruptions may also not return year after year if the volcano is dormant.
Overall, the answer to this question will depend on the context and the sources of silver dust.

How do you prune a dusty miller after winter?
Pruning a dusty miller plant (Centaurea cineraria) after winter is essential for keeping it healthy and attractive. Pruning helps maintain the shape of the plant, encourages more branches and flowers, and prevents disease and pests.
Dusty millers should be pruned once a year at the end of winter to promote new growth.
First, use bypass shears to remove any dead, dying, or injured stems from the plant. This will help the plant get rid of unhealthy growth, create air circulation within the plant, and promote healthier branching and growth.
Be sure to cut the stems close to the base or branch of the bush as new branches will grow from these areas.
Next, cut back any other overgrown or out-of-shape branches. To help maintain an even-looking shape to the bush, use a stepladder and start by trimming the top part of the bush. Work your way down the sides and keep the sides of the bush slightly lower than the center.
If a branch is too large or dense, use loppers to make long, clean cuts just above a node or leaf. Continue to prune as necessary until you achieve the desired shape.
Be sure to disinfect your tools with rubbing alcohol between cuts to help prevent the spread of diseases.
After pruning, apply a balanced fertilizer to help promote strong, healthy growth. Follow the fertilizer instructions for the correct concentration and amount. Finally, water the plant frequently to keep the soil consistently moist until it’s established.
How often should I water my dusty miller?
