A first batch of soil (3.1) is placed inside the bottom of the pot (1), then a barrier part (2) is used to divide the pot into top and bottom chambers (1.1,1.2) and a second (and optionally a third) batch of soil (3.2) is placed in the top chamber (1.2). Seeds or seedlings are planted in the batch of soil above the barrier part, the composition of which is different than that of the batch of soil above and/or below it. |
