Growing Tip #1: Don’t overwater!

The less glamorous, but essential aspect of being a CowPot;
fungus and sometimes mold.

Don’t worry, we’ve got some growing tips to share with you.

We take great pride in the natural ingredients we use to make CowPots. For centuries gardeners, farmers and growers have discovered the value of using cow manure as a soil amendment. At CowPots, we’ve just helped by innovating a new and unique way to get that manure into the garden.

So we remind all of our gardening enthusiasts, CowPots may not look like manure nor smell like manure, but they are manure, and thus decompose, biodegrade and add value to your garden just like manure does. For our friends that have visited cow pastures after a herd of grazing cattle, it is not uncommon to discover mushrooms growing from the cow patties left behind. This natural cycle of decomposition is also apt to happen on CowPots just as it does out in the pasture. We are happy to share some growing tips to help you manage mold growth.

If you have fungus or mold on your CowPots…

We have completed countless experiments and tests on the molds and mushrooms found growing on CowPots, and none have ever tested harmful.

The growth of mushrooms is natural and is proof that CowPots are a great growing medium.

2 growing tips to reduce mold and fungus growth on CowPots:

Growing Tip #1: Do not overwater! As shown in the picture of tomato transplants (on left), planted at the same time, yet there is a noticeable distinction in the pot walls. The difference being the amount each pot was watered. When CowPots are allowed to dry between watering, their walls become a less inviting home for mushrooms and molds which grow best on moist surfaces. Allowing the CowPots walls to dry, the process of decomposition is slowed down, increasing the shelf life of your potted plant before transplanting.

Growing Tip #2: Allow for space and ventilation between CowPots. Ventilation helps to dry the CowPots’ walls between watering. This will also encourage better plant growth by allowing plant roots to breathe and improves air pruning.

Fungus and molds are easily managed within the suggested 12 weeks we suggest as a shelf life of planted CowPots. After 12 weeks, it is these same fungi and molds that make the magic of decomposition occur so that CowPots continue to be 100% Biodegradable and safe for you, your family, your plants and your garden. In fact, CowPots had the best rate of decomposition of all the biocontainers in a recent university trial. Read more about that trial here.
