What is powdery mildew?
Powdery Mildew is a fungal disease that’s common in plants exposed to humid environments with low light exposure. Overcrowding plants in your garden can increase the likelihood of this disease as well. Plant leaves infected with powdery mildew will gradually turn yellow, die, and fall off. The disease can also spread to the stems of the plant. This disease has been more prevalent this year due to the environmental conditions created by smoke from the wildfires in Canada.

Perennial plants such as Aster, Hollyhock, Bee Balm, Phlox, Columbine, Joe Pye Weed, Coreopsis, Delphinium, Geranium, Lupine, Rudbeckia, Salvia, Veronica, Yarrow, and Heliopsis can be prone to contract this disease.

Slugs are most active after dark, between the hours of dusk and dawn. If you are gardening during the day, chances are you won’t see them. In the light of day slugs hide in damp places such as under stones, ground cover, planters, and even burrow into the soil to avoid dehydrating.
What common plants do slugs attack and eat?
Slugs are known for eating basil, beans, cabbage, dahlia, delphinium, hosta, lettuce, marigold, and strawberries just to name a few.
What does slug damage look like?
If you see rounded smooth holes that are more often in the center of your leaves than the edges this is most likely slug or snail damage. You may also see evidence of their slime trails on the plants as well as on the top of the soil.
