Planting Tips & Trends

What is Downy Mildew?

Impatiens downy mildew is a foliar disease that is capable of complete plant devastation.  Although sporadic back in 2004, today the disease seems wide spread and here to stay, at least for some years to come.

How does it spread?

Water splashing spores off an infected plant can spread the disease, but perhaps the most alarming method is the wind.  Air currents can carry the infected spores for hundreds of miles, until they finally settle in a flowerbed somewhere.  Which means if your plants are located in an area that receives wind your impatiens can get downy mildew.  Plant these flowers with caution.

Early Symptoms:

Light-green yellowing or stippling of leaves

Subtle gray markings on upper leave surface

Downward curling of infected leaves

White downy-like fungal growth on underside of leaves.

Advanced Symptoms:

Leaf and flower drop resulting in bare, leafless stems

Infected stems become soft and plant collapse under cool, wet conditions.

Once a plant is infected it can not be saved. Remove any infected plants and discard to help prevent spreading.

Recommended alternatives that love the shade:

Pruning encourages the plant to expend its energy on producing new blooms instead of going to seed (and ending its life cycle/going into dormancy). For delicate stem plants such as pansies, nasturtium, and alyssum you can simply pinch off the dead flower at its base using your fingers.For harder stalk plants such as sunflowers or …
