Planting perennials in the fall is a no-brainer. The cool, moist autumn weather encourages quick root growth, allowing your plants to become well established before winter strikes, and by the time spring arrives they’ll be in launch position to burst into bloom their first year. Just try to get your plants in the ground at least 4 to 6 weeks before the first expected hard freeze in your area.
Not all perennials benefit from fall planting, but many of my favorites actually prefer it. Peonies, hostas, daylilies, iris, phlox, and Asiatic and Oriental lilies are just a few examples. And, if you already have these perennials in your garden, fall is the perfect time to dig and divide them to keep them from becoming too crowded.
Of course, the key to success with fall-planted perennials is water. If rainfall is scarce, water them every day for at least the first ten days after planting. Also, tuck them in with a thick blanket of mulch to conserve soil moisture and protect them from heaving out of the ground during winter’s freeze/thaw cycle.

So, as the gardening season starts to wind down, just remember that once winter arrives you’ll have plenty of time to relax. Get out and plant while you still have the chance.
