So a little update on the dahlias and watercress experiments: The dahlias, seen above, are doing fabulously well. They are about an inch tall already, and only took four days to germinate. I think they are quite determined to grow.
As for the watercress, it is quite happy in it's little bog. The seedlings have stretched to an inch or so tall, and their teeny first leaves are growing larger. There are masses of them, which is lovely, and at the rate they are growing, it won't be long before they are ready to transfer to their future aerated-bucket homes. I envision egg and cress sandwiches for tea in the garden this spring
