Spring is the perfect time to divide and plant herbaceous perennials. After 2-5 years clumps of most perennials become overcrowded and their vigour deteriorates. As a result plants produce fewer flowers, and loose some of their ornamental value. As a general rule, spring is the best time to divide and plant summer- and autumn-flowering plants (starting with mid-June), and ornamental grasses (miscanthus, reed grass, feather grass).
