Should i prune coreopsis

The reasons I always cut standing perennials down in fall is i neatness, being able to monitor and deal with what's going on with the perennials at ground level, being able to weed effectively, and ii next spring, being able to see spring bulbs especially the earlier smaller things like crocuses and not wanting to walk on beds when they're wet including from snow melt.

In the latter case, don't want to damage the later spring bulb or low spring perennials. Spend a lot of time staking plants and always happy that don't have to stake things like Coreopsis an Gaillardia which have very long potential bloom times.

I do spend a lot more time deadheading, including Coreopsis and Gaillardia to keep the blooming going. Cutting back in fall is sort of out of vogue in the gardening world right now. But I think if it were really catastrophic for perennials, it wouldn't have survived for so long as a practice. I think it is just a matter of preference. DiSabato-Aust's recommendation to cut back heavy flowering perennials in late summer but not for winter comes from the work of Hansen and Stahl in their book Perennials and Their Garden Habitats.

I do not know if they tested their theory or if it is just a theory with no data to support it. DiSabato-Aust does caution that if you do cut back, to only cut back within " inches of the ground because some of the basal buds for next season do develop slightly above or at ground level. Not sure if this applies to Coreopsis or not. I also grow bulbs in my perennials beds so I usually cut back in very early Spring and often before new growth comes from the perennials -- which is not exactly what is recommended -- but it hasn't caused any problems so far.

Agree, Scott, it is a matter of "preference", or, perhaps should be sure you would agree of "informed preference". Must say I'm a bit sensitive to anything approaching top-down pronouncements in gardening, "abhominable magenta" viz.

Related Discussions Do you plant bulbs in your yard? While peonies are not a bulb they've been introduced to this discussion so I'm going to take the opportunity to tell you about my own experience with them.

People say that peonies don't like to be moved or disturbed. They are hardier than we've been led to believe. When my parents were downsizing I begged them for the glorious old peonies in their garden. These were special plants as they bloomed most years around the time of parents' wedding anniversary.

If the coreopsis is severely affected by leaf spots, powdery mildew or another leaf disease, it is possible to address these diseases by pruning back the plant severely enough to remove most or all of the affected foliage following flowering to encourage a flush of healthy new growth. With many plants, the addition of a layer of compost to the growing area in the fall can help prepare the soil for a rich, rewarding springtime. This is not the case with coreopsis.

All it requires is for the soil to be well-draining. Nutrient-rich soil can encourage leggy growth. If you do wish to fertilize, do so in the springtime. Add a three- to four-inch layer of organic mulch, such as chopped leaves , bark chips, or straw to the soil surrounding your plant.

If you live in Alaska like I do, or in another area where winter grips the land for five or more months of the year, and the ground freezes for long periods, add an extra two or three inches of mulch. If you have cut back your plants, you can apply leaves or straw over the top of the plant to further protect and insulate the crown.

Remove this additional layer in the spring after the danger of frost passes, to give your plant some room to grow. With just a few extra steps in fall, you can help ensure that it survives the winter and brings its bright blooms back to your garden the following summer.
