My dill seems to have a whitish coating most of it. It looks almost powdery and gives it a pale bluish hue.

    Looks like it needs watering, apart from the mildew - there is a connection between dryness at the root and susceptibility to powdery mildew.

  • I damaged this plant a week or so ago. This photo is just after I cut the damaged sections off. More than half the plant. I tried to get it to stop overhanging the pot and support it in a more upright position and heard several cracks as I did so. :( As for watering, this is the driest they have been in a long time. You helped me with my mould problem 3 or so months ago telling me my plants need more space for air flow to dry out a little (fungus problem in my oregano). That did work, but we have had a mild/wet/overcast winter here which took a long time to have the damp go away. Commented Sep 26, 2016 at 9:31

Taking your other question into account as well, you have an infestation of powdery mildew in your garden - and your dill is almost covered with it.

As we are talking about edible plants, I strongly suggest you spray with dilluted milk before grabbing a "chemical" fungicide.

We have a bunch of questions and answers on the topic, the poster here has a similar problem, and our search site gives this list.

  • I thought it might be that. I just got rid of it from my rosemary plants. But it's on a few plants now. Commented Sep 26, 2016 at 8:58
