Recognizing Downy Mildew
One thing I’ve learned through my years of gardening, is that the key to dealing with plant diseases like Downy Mildew is to catch them early. Look out for yellowing leaves often accompanied by a fluffy white growth – this unhealthy duo screams Downy Mildew!
Prevention is better than cure
A principle that's never failed me when combatting plant diseases is this wonderful adage: 'Prevention is better than cure.' For Downy Mildew, this means controlling and spacing out your plantings. Why, you ask?
Well, Downy Mildew thrives in damp, crowded environments. By ensuring good air circulation, you can help prevent an outbreak before it even begins. Increase the sun’s exposure to your plants and keep the leaves as dry as possible during watering. Watering in the early part of the day also helps to quickly dry out any excess moisture before fungi can take hold.

Diagnose the issue
Before you begin spearheading your offensive against Downy Mildew, make sure you’re actually dealing with Downy Mildew and not something similar. Anything that can resemble it, like powdery mildew, requires a completely different approach. Know thy enemy, as they say.
Treating Downy Mildew
If you’ve already spotted an outbreak on your plants, then grabbing a fungicide is your best bet. I’d recommend investing in something high quality and organic. Nothing beats the peace of mind knowing you're doing your bit to treat your plants and the environment right.
You should see a notable reduction in the disease once you treat affected plants with the fungicide. Keep a watch on the treated plants and continue the treatment till you see complete recovery.
A gardener’s choice: Plant Resistance
Another method, which might require a bit of planning, is to choose plant varieties that are resistant to Downy Mildew. Certain hybrids have been bred for just this reason, and while they won't be invincible, they will definitely show more resilience.
There's no better feeling than looking at a garden flourishing despite of diseases. It's what makes us gardeners sleep with a smile, isn't it?
