Prevent Damping Off In Seedlings With A Crucial Soil Tip

There is nothing more disheartening for a home gardener than checking on a tray of cute baby seedlings only to find that they've collapsed overnight. Yesterday, they were reaching for the sun, and today, they're slumped over with shriveled, gray-brown leaves. This is frustrating to see, and it's caused by a deadly disease called damping off that comes from fungus or mold in your soil, like Pythium or Phytophthora, for example. This is common if your seedlings don't have enough air circulation, the soil has poor drainage, or if there's too much humidity.

To beat this garden villain, know that damping off is a soil-borne disease. Many beginner gardeners make the (understandable) mistake of using random dirt from their yard or soil mix from an old open bag. While plants become increasingly less vulnerable to damping off as they grow, young plants of any variety are just too small to have any sort of immunity to it. Unfortunately, if this scary garden villain takes hold, it wins, leaving any infected seedlings to just wither away. The good news is that you don't need any fancy chemicals or a ton of must-have gardening supplies: all you need to do is just change the way you think about the ground you put your seeds in.

The most important tip for preventing damping off is to remember that prevention is key, so keep any potentially contaminated soil away from your seedlings. Instead, opt for a seed-starting mix or some soil that's been sterilized and is well-draining. You can test if the soil drains well by watering a few non-planted seedling pots and seeing if it empties properly.

You'll also want to make sure your seed starting supplies are clean for an even more sterile environment. Another pro move is to add a light layer of either vermiculite or cinnamon atop your new seedlings. Why? Vermiculite is good at slowly releasing water and nutrients, and keeping soil aerated, and cinnamon is a natural, mild fungicide that'll help keep any sneaky fungi away so the seedlings can stay safe and healthy as they continue to grow.

With the combination of a soil-less potting mix and a safely dried-out top layer, you banish any zones near the seedling where a dangerous fungus could potentially be hanging out. It's a pretty easy tweak to the potting process on your part, but it makes a world of difference to each seedling. This approach lets you say goodbye to damping off issues and hello to happy and healthy baby plants. Soon, you'll be ready to harden off your plants and move them outside!
