What is Damping Off?

If you haven’t had the “pleasure” of experiencing damping off, consider yourself lucky! This horticulture disease thrives in cold, wet soil and is caused by mold or a fungus.

It appears as a fuzzy, moldlike growth on plant stems, seeds, and even soil. Damping off occurs most commonly in seedlings, particularly those that are grown indoors or in a greenhouse with high humidity. Sadly, most seedlings that get it struggle to survive, and typically don’t. This can be a real tragedy when you have lovingly grown your seedlings and have been looking forward to planting them!

Thankfully, there is a simple, inexpensive way to prevent damping off that costs just pennies (or even free!)…chamomile!

How to Grow Chamomile

Chamomile in Garden

Chamomile is a cheerful, dainty herb that flowers into a pretty white flower with a yellow stigma. Their beautiful appearance coupled with the host of medical benefits (see more below) makes them a prime candidate for adding to your herbal garden.

The best way to grow these tiny daisy-like flowers is to start with seeds in the early spring before the heat of summer hits. It’s best if chamomile grows in its own bed–you are likely to get a better harvest that way.

When to Harvest Chamomile

Wait until the flowers are fully opened before harvesting them. This takes about two months from the time you first planted them, so late spring or early summer is when you can expect your first crop.

Chamomile flowers are, of course, edible. The blooms can be infused in oils, sprinkled on top of baked goods, and added to salads. You can even infuse chamomile flowers in liquor to create cordials!

Plus, you can use and harvest chamomile leaves as well. Add them chopped to your salad or steep them to make tea. Be forewarned that the leaves can be slightly bitter.

Both the leaves and the flowers can be enjoyed dried or fresh.

Benefits of Chamomile

Chamomile is a flowering herb that has long been used for a variety of ailments. Many people are familiar with chamomile tea, and choose to drink it to help with sleep and relaxation. In fact, chamomile has been approved by the official medical authorities of over two dozen countries to treat conditions such as indigestion and even colic in young babies!

Using the medicinal properties of chamomile is nothing new to our world though. It’s been used for thousands of years by the ancient Egyptians, Greeks, and Romans

This powerful flowering herb is gentle and smells incredible. Plus, the little white and yellow flowers always bring a smile to my face.

However, chamomile offers a host of other benefits which include:

  • Lowering blood pressure
  • Reducing swelling and inflammation
  • Help boost immunity
  • Reduces discomfort from hernias
  • Assists with relieving menstrual pain and stomach upset

Chamomile as a Fungicide for Plants

Even more interesting, chamomile is antifungal. This means you can harness the powers of a plant from your garden to treat a whole new crop of plants growing in your garden.

How to Make Fungicide Spray with Chamomile

Making this fungicide for plants is both simple and effective! With a few minutes of hands-on time, you’ll be able to create a powerful tool to protect your seedlings.


  • 1 part fresh chamomile OR 1/4 part dried chamomile
  • 3 parts rainwater or dechlorinated water**

**Dechlorinating water is simple! Tap water that comes from municipal sources is often treated with chlorine. We want to remove that so we can encourage the growth of beneficial organisms and help the plant to thrive. If you don’t have rainwater available, just put tap water into a bucket and allow it to sit for 24 hours. By then, the chlorine will have evaporated off. Alternatively, you can boil water which works perfectly if you are making tea.

Make It

There are two ways to make this fungicide spray—you can choose between using the fresh herb or using the dried version. You can use both the flowers and the leaves of the chamomile plant.

With Fresh Chamomile

Harvest fresh chamomile flowers, leaves, and stems, in the early morning when flowers are at their peak of perfection. Make sun tea by letting your flowers and leaves infuse in a mason jar of dechlorinated water in your garden or on a sunny windowsill. Let it infuse for a day.

With Dried Chamomile

When you are using dried chamomile instead of fresh, the process differs slightly. Here you’ll still want to brew a tea, but I recommend you do so by pouring boiled water over the dried buds and letting it steep for 24 hours.

How to Make the Damping Off Spray

  1. Brew your tea (see above).
  2. Strain the tea, cool, and use.

That’s it! Simple, right?

How to Use the Chamomile Fungicide for Plants

You can use this spray in one of two ways. First of all, you can use the mixture to water seedlings. Alternatively, you can pour the mix into a spray bottle and use it to mist plants and soil daily.

If you have established plants, you can also use this chamomile damping off spray as a foliar spray to prevent disease.
