General Marginal Care:
All our plants will come potted in aquatic compost. Our 9cm plants come in a solid pot, so will need to be repotted.
The 1ltrs and 3ltrs will come in Finofil aquatic baskets ready to be placed on your pond shelf at the required depth (use bricks to change the depth if required). The mesh pot allows nutrients and oxygen from the pond to flow through the pot without any soil loss.
Each plant also comes with a comprehensive label offering further planting advice.
