My friend, Robin, owns a lavender farm and is a wealth of wonderful information and ideas regarding lavender. As a "Master Gardener", she has studied plant propagation, soils, and growing techniques. And best of all, she's happy to share all she knows! The lavender in this picture is hers. She's in the midst of her spring pruning. These lavender plants were cut back 1/3 to 1/2 in the autumn, and now they are just receiving a mini-pruning with hedge trimmers to encourage new spring growth.
