|When is the best time to divide Peonies? Our plants are many years old, and I think they need some rejuvenating.
Also, I cannot seem to grow sweet peas as a vine - any suggestions? The sprout from seed, but don't seem to do much after that.
|Peonies resent being disturbed, but fall is a good time to lift and divide or transplant peonies. Keep in mind that they will take some time, possibly several years, to settle in and recover. Be careful to replant them so that the eyes are only about two inches below the soil surface. Planting too deep will prevent them from blooming. Once planted ion a favorable spot, peonies can be left in place for decades and should perform very well for years and years.
Sweet peas love rich, moist soil and long, cool summers. If your plants are not performing well, perhaps it's because of your summer weather. You may be able to circumvent that by planting in very early spring so they bloom before the hottest weather arrives, or planting in mid-summer for a late summer, early autumn display of flowers.
