Coreopsis grows best in a site with full sun to part shade and well-drained soil and prefers soil with high fertility. Work an amendment like aged manure or well-rotted compost into each planting site to improve soil drainage and fertility. Mix amendments in so that the amendment makes up no more than 50 percent of the soil.
Dig up the coreopsis plant with a shovel, sharp spade or garden fork, working around the perimeter of the plant to loosen. Lift the clump out of the ground, cleanly severing any roots that remain attached with a sharp, clean knife or spade and gently remove any loose soil to expose the root system.
Tease clumps, or divisions, apart from around the perimeter of the parent plant. Gently pull of sections that each have three to five healthy, vigorous shoots and an adequately-sized section of root system. Discard the spent, old center of the plant. Most perennials are best divided in spring when they are showing a couple of inches of growth, so this is a good time to make your divisions.
A very general rule of thumb is to divide perennials that flower from early spring until the middle of June in early fall, though I generally divide these shortly after they finish flowering, with good results. The plants then have an entire season to recover before flowering again.
Perennials that flower after the middle of June should be divided in early spring and will often flower the same year after being divided. Many gardeners successfully work outside of these general timing guidelines when dividing perennials, so plan your work when it is best for you and, ideally, the plants.
Try to avoid dividing plants when they are flowering. There are some plants that are best divided in a more specific time frame.
For example, peonies are best divided in late fall and true lilies Lilium in mid- to late fall. Then there are plants like hosta and daylilies that can be divided at nearly any time. Once, I left hosta divisions above ground over winter and then planted them in spring when they started growing.
I do not divide the perennials in my garden on any kind of routine schedule but do monitor the garden for needs. If a perennial such as an ornamental grass or Siberian iris has developed a dead center, then it is time to divide and replant the healthy portions from the outer edge.
Some perennials such as Zagreb threadleaf tickseed Coreopsis verticillata 'Zagreb' will continue to expand and take over sections of your bed without occasional dividing. Don't blame yourself for killing them. For me some of the newer yellow ones did not over winter either, or if they did, they were weak and spindly. One example of this was Creme Brule. The deep yellow ones are generally the toughest, longest lasting ones, with names like Sunburst, Early Sunrise, Zagreb, Golden Gain, etc.
The latter two are examples of verticillata, like 'Moonbeam', only more vigorous. I have clay soil, which is not the best for coreopsis. They seem to prefer a more sandy, open growing medium.
That could contribute to my overwintering losses. Indem Sie weiterhin auf der Website surfen bzw. Mehr erfahren. Ultimate Lighting Sale. Bathroom Vanity Sale. Bestselling Chandeliers and Pendants. Sign In. Join as a Pro. Houzz TV. Houzz Research.

Related Discussions Need ideas how to landscape our front yard Q. I, too, live in the country with lots of wildlife. I looked at your profile and you have saved a lot of good ideas for your property.
I think it is a very good idea to set aside an area for raised vegetable beds that are completely fenced. If you are new to your area I recommend driving around to your neighbors to see what they are growing and what the wildlife is leaving alone. It will be quite a challenge to have a garden with wildlife but it can be done with patience and knowledge.
Kitasei's suggestion about contacting the agricultural extension office in your area for a list of plants is a good start. My dog sleeps inside at night but the fact that he is around all day keeps the deer damage to a minimum.
I fight gophers, ground squirrels, deer, raccoons, coyotes, jackrabbits and birds. But think how lucky we are to live in the country!
