Growing & Maintenance Tips for Lavandula angustifolia 'Blue River'
Lavandula angustifolia grow best in an average to dry, well-drained soil, in full sun. Excess, winter moisture may cause the stem to rot and hot, humid summers may cause the leaves to blacken and the plant to deteriorate. Prune flower stalks to encourage more blooms. In the spring, prune plants to desired size or back to the old woody stems, to promote vigourous growth and keep a dense, compact habit. Please note: lavenders should never be pruned harder than half way down the stems. Because of its strong scent, plants can be added throughout the garden to deter insects. In mild climates lavenders are evergreen.
