Surprisingly successful veggie growing in cool Canberra. Bought the Birdies bed in February, filled it in March with organic matter, compost and garden soil, sowed lettuce, bak choy, broccoli and cauliflower seeds in early April and by the end of April harvesting lettuce and bak choy and looking forward to more crops.
