Yesterday I planted some more seeds in my stacking pots - some Lettuce, Pak Choy, Marigolds and Parsley. I put the Pak Choy and Parsley in together - it will be interesting to see how they go.
The stacking pots have 4 levels of 3 growing areas - think of it in terms of 4 triangles stacked on top of each other. I have bush cucumbers in the top - which are sprouting - and then 9 more growing areas in the next 3 levels down. I wondered what to put where. In the end I staggered them in so I have each of the varieties in each of the levels in a spiral-like fashion. I also moved the stack a bit further away from the house so it will get rained on when it rains.
I bought my set of stacking pots from here - Productive Gardens. Their service and delivery was very prompt. I am very happy so far with my pots.
