A founder wants to convince the jury in "The Lion's Den" with her "gold leaf" fertilizer blankets, which are wrapped around the root ball of plants.
No, "gold leaf" is not a decorative material for chocolates - unless you lovingly name your flowers.
Instead, a founder from Bergisch Gladbach presented the jury of "Die Höhle der Löwen" with an organic long-term fertilizer in the form of cloths that promise garden and indoor plants quick yields and great growth.
"The Lion's Den" (Vox): "Gold Leaf" - fertilizer for plants

Not infrequently, our grandmothers already knew from long-standing experience how to keep house and garden going with simple means and as little effort as possible.
Sabine Wirz-Springe (58) took up this idea: Even as a young girl, she spent a lot of time in grandma's cottage garden, where the most beautiful flowers and lots of fruit grew.
For good reason.
The secret behind this was their method of fertilization: horse droppings were packed in old jute potato sacks and these were then worked into the beds.
"This had the huge advantage that the plants were continuously supplied with fertilizer," reports the founder.
“Even back then, the results of my grandmother were right.
She was the most famous gardener in our village.”
Nowadays, if you want to fertilize flowers, you often use a liquid fertilizer instead, but "after watering once and it rains or I water again, the nutrients are washed away from my plant," explains Sabine Wirz-Springe.
She was looking for an alternative and it was wet wipes containing organic fertilizer made from natural fiber pulp.

Depending on the size of the plant, wrap one or two fertilizer cloths around the root ball and then put them back in the flower pot or bed.
In this way, the plant should be continuously supplied with nutrients, vitamins and minerals.
The "gold leaf" is also environmentally friendly: the cloth is biodegradable and composts by itself after about six months.
