Growing Ferns: From Spore to Potted Plant

Have You Ever Wondered How Ferns Are Grown?

In our greenhouse, we have developed a meticulous process to grow these stunning plants from tiny spores into fully developed ferns. Take a peek behind the scenes and discover how we make it happen!

It All Starts with the Seed Trays

Growing ferns begins with the smallest building blocks of a fern: the spores. These are carefully sown in specially prepared seed trays. The trays are filled with a fine, airy soil mix, ideal for germination. The spores are evenly spread across the surface and left uncovered, as they need light to germinate. The trays are then covered with plastic sheeting to create a humid and warm environment. After a few weeks (or sometimes months), the first signs of life appear: tiny heart-shaped structures called prothallia, which form the foundation of the fern plants.


Transplanting: Creating Space to Grow

Once the prothallia have grown into small fern plants, it’s time for the next step: transplanting. This involves carefully moving the young plants to a new environment with more space. At this stage, each plant receives individual attention. We place them in specially designed trays, which can hold between 100 and 250 plants depending on their size. By giving the plants enough space, they can grow without competing for light and nutrients.


Potting: Ready for the Big Stage

As the ferns grow larger and stronger, they are ready for their own pots. We use pots of various sizes, ranging from 5 cm to 14 cm in diameter. The young ferns are gently transferred and firmly placed in the soil. An initial watering helps them settle into their new environment. These pots are placed in a controlled setting where the light conditions and humidity are perfectly adjusted to support their growth.


Final Care

Our care for the ferns doesn’t stop after potting. We closely monitor them to ensure they remain healthy and continue to grow optimally. Regular watering and adjustments, when needed, are essential. Through this process, our ferns grow into strong, beautiful plants, ready to begin a new life in your home or garden.

With love and attention, we ensure every fern gets the best possible start. Bringing a touch of nature closer to you!
