We were lucky enough to be given for Christmas by my boyfriend's brother a starter kit for getting going with our edible window boxes. Goodies included some window troughs, seed trays, a trowel and seeds to get us going on a "pizza and pasta pot". Two weekends ago we planted up some of the herb seed mats in little pots.
We left them covered in clingfilm on the table by the window and 11 days later the basil, coriander and chives have popped their heads up! As of yet there's still no sign of the parsley or mint... Fingers crossed they're just taking their time.
