Perennial Plants - Care and Maintenance of Flowering Perennials

It's misleading to think that once you plant a perennial flower you are done with it. To have great looking perennials, there is a good bit of maintenance involved. This includes dividing, deadheading, staking, cutting back and other chores, depending on the perennial plant. Here are some tips.
Deadheading, Pinching and Cutting Back - Garden Maintenance
Flower gardens require constant maintenance to look their best. Common garden chores like pruning, pinching and deadheading are easy to master, as show here in this step-by-step photo tutorial.
Dividing Bearded Iris
Bearded Iris are tall, elegant additions to the flower border, but they are also relatively high maintenance. You can help cut down on the incidence of soft rot and borer damage through regular division of the iris rhizomes, every 2-3 years. This will also keep bearded iris performing and blooming at its best. Start by carefully digging and lifting the rhizomes, as shown here.
Dividing Perennial Plants
Most perennial flowers will need to be divided to remain vigorous and continue blooming season after season. Division of perennials is an easily mastered gardening technique that is good for the plants and your garden.
