How to Dust Your Garden Plants


Everyday air pollutants, road dust, long stretches of drought and construction dust can quickly begin to diminish the beauty of garden plants. More importantly, heavy dust accumulation can also block out some of the available sunlight from reaching and being absorbed by plant leaves. Rinsing with the hose can often be the answer, but is not an effective choice for every plant--particularly if it needs to be done frequently.

Step 1

Run a new, inexpensive and dry natural-bristle paintbrush over the leaves of velvety textured plants, such as geraniums, gerberas and lambs ear. Brush dust off of the heads of delicate flowers that cannot be hosed off, such as roses, hydrangea, gerberas, gardenias and dahlias.

Step 2

Rinse the dust off of shrubs, trees and hedging with the garden hose, using an attachment with a heavy-rain or equivalent setting. Rinse until the dist is displaced and the plants look refreshed.

Step 3

Water over the heads of delicate annuals, perennials, bulb flowers, and other bedding and container-grown plants with the hose attachment set on a light-rain or heavy-mist setting. This may take a bit longer to wash all of the dust away but will reduce the chance of harming the plants.
