You've got me so curious Lara...may have to try that too, but not in my herb garden...thanks for the warning! Have resisted planting anything because last night we had another freeze. The sack of perennial bulbs I bought are starting to sprout in the bag so am feeling some pressure to get them in the ground. I have a raised bed herb garden and the sage, mint, chives are all up and spreading...want to get rosemary and sweet basil in but they don't like the cold.
