why does my parsley have a white powder on it?

Question

I'm growing parsley indoors, and it's been doing very well. Just in the last few weeks, there's a white powder on the leaves and it's spreading. Did I over feed it? (I use Miracle Grow) Is it from other plants in the conservatory? Very new to gardening and appreciate any advice.

Answer 1

Mildew or spots from foliar fertilizing/spritzing.

If mildew, you need better air circulation in the growing area, it's too wet or your daily temperature changes are too great.......only about 10-15 degrees between day and night ....if possible. If the plants are in pots, you can wash mildew spores off the plants, truck them to the sink and rub with fingers. The mildew is actually within the upper cell layers of the leaves. You might want to remove those. Wash your hands! Of course the spores are throughout the growing area.......so will take some clean up (weak chlorine bleach) for pot outsides, benches, etc) and really improving the air circulation.

Fungicides will help curtail spead but do nothing for infected plants.

If water spots from misting.....stop. the spots rub off.

Answer 2

Are you sure your parsley wasn't smuggled from Columbia
