5 Tips to Make More Profit from Mushroom Farming in the UK

Gourmet mushrooms such as shiitake, button, and oyster mushrooms, and medicinal mushrooms like lion’s mane are among the most profitable mushrooms for small-scale producers.

Most small growers focus on growing these two groups of mushrooms for local consumers, and while they are both profitable, they cannot be considered cash crops. They don’t provide quick money, but instead, need intensive labor and hard work.

With all the quick-growing tips to speed up the growth of your mushrooms, it is easy to fill in the high demand for gourmet and medicinal mushrooms in the market. But to be successful in the business, one needs to put on a lot of effort and patience, especially when waiting for your mushrooms to fruit.

Creativity and a good marketing strategy are also needed to be able to sell your mushrooms. Below is a list of some areas that will make your mushroom farm more profitable:

1. Sell your mushrooms directly to consumers

You can do this by selling your mushrooms to local farmers’ markets. They have customers that are interested in high-quality and healthy foods. Some farmers have established their own company stores that offer gourmet items for sale.

If you don’t have time or money to invest in your own stand, make friends with other vendors and offer a commission to get their help in selling your products.

2. Sell your mushrooms to local restaurants

The success of local mushroom growers relies on consistent sales which pay at a good price- which you can find in restaurants. Regular sales and delivery to local restaurants is a powerful tool for success in the mushroom industry.

The only hindrance to this idea is finding your clients and keeping up with the demand. A good tip for finding clients is by cold-calling as many restaurants as you can.

3. Sell your mushrooms to grocery stores

More grocery stores these days have been stocking gourmet mushrooms and most of them buy from out-of-state distributors. If you can provide fresh, healthy, and tasty gourmet mushrooms, then your business is up for a good sale.

However, you will need to have an established business with insurance before selling via grocery stores.

4. Join a food cooperative to sell your mushrooms

Cooperatives exist to help their member sell their products. They have more advantage than a farmer’s market because they are more established and remains open all year round.

5. Sell value-added mushroom food products

These are mushroom-derived products that you can sell to increase their value. You may have mushrooms that are too small to sell or have cosmetic flaws, and they can make up as good ingredients for another mushroom product. Examples of these products are the following:

  • Dried mushrooms: This is a good option to hinder mushroom spoilage due to low sales.
  • Mushroom sauce: usually derived from shiitake mushrooms; is a favorite of foodies and can be a sole source of income by itself.
  • Mushroom croutons: derived also from shiitake mushrooms and can be an alternative for traditional salad croutons and even a casserole ingredient.
  • Pickled mushrooms, mushroom jerky, and even growing kits can also be sold to gain more profit from your mushroom crops.
