In the trial year 2023/2024, initial experience was gained at the LVG Hannover-Ahlem with the new co-plantable pot “Bioplasmar”. The publication on hortigate.de reports on the results of this test.
The 10.5 cm pot used consists of washed, dried green waste compost and is suitable for cultures lasting up to six months. The pot is both home-compostable and fully biodegradable. After 20 weeks, the primroses in the Bioplasmar pot reached similar sizes and qualities to those in the conventional black plastic Teku MXC pot.
However, the difference in root development was striking: while the primroses in the plastic pot showed the usual good root mass, the plants in the Bioplasmar pot had less root mass. These results correspond to previous experience with other co-plantable pots.
At the end of the trial period, October 2023 to March 2024, the Bioplasmar pots were still largely stable. Around 25 % of the plants showed cracks at the bottom of the pots, but these should not affect the marketability of the plants.
