I have a back yard veggie patch and grow most of my own food there. As I am in Queensland, I can garden all year round, moving from summer to winter crops as required. For a long time I only ever planted food-producing plants and considered growing flowers, just for their beauty, a luxury and a waste of space. Then one year I grew flowers in the garden, alongside the veggies, and noticed a significant increase in the yield for that year. This was due to the fact that the flowers attracted more insects, and in particular bees, to my garden and I, therefore, had a much higher rate of pollination, resulting in better fruiting of my plants.
Since then I have been planting flowers with my veggies every season. I had some successes and some failures until I learned what flowers to plant when. I was used to planting the right veggies for my location and time of year, but not flowers. That was where the Flower Growing Guide came in handy. I now take this laminated guide into the garden with me, along with my Vegetable Growing Guide and plan out all my garden beds for the season.
