Another aspect of perennial care is weeding. Much of work the work that should be done when installing the bed is removing perennial weeds, using a weed mat and mulching well. However, even a well-planned garden can fall prey to pesky weeds. Hand weeding the garden is most effective. It's vital to pull weeds before they mature so that they don't take needed nutrients from the perennials and leave seeds in the garden.
Perennials have enough work growing without competing with weeds for food, water and space.
Weed seeds can lay dormant in soil for long periods before germinating. Take care not to leave any sections of the weeds in the soil, for they will often grow back from small pieces of root or other plant material. After the weeding is done, consider the need for additional mulch. Mulch upkeep is one of the best maintenance practices available to keep a perennial garden healthy. Recommended mulches include many organic materials, from pine straw to shredded pine bark and compost.
