How to Divide Geum Plants for Cut Flowers
Growing Geum as Cut Flowers
Geum are a compact perennial producing semi-double blooms in early summer. Cut flower stem length ranges from 15-18” making Geum a wonderful accent for floral arrangements. Hardy in USDA Zones 5-9, with some varieties down to 4, they need to be divided every few years to remain vigorous. Here’s how to divide your Geum plants quickly and easily.
How to Divide Geum Plants
First, locate the clump you want to divide. Clumps in need of division may be flowering poorly or lack vigor.
Next, carefully dig around the clump, preserving as much of the roots as possible. As you loosen it, begin lifting the clump away from the ground.
Once lifted, gently shake away any loose soil.
Each section of green leaves, or shoots, will become a microdivision.
Now, gently begin to pull apart the clump to create those micro divisions. Keep in mind that each division will need to have shoots, roots, and rhizome attached.
Once you begin, the process is quite simple, as the small divisions separate easily.
Continue teasing apart the green shoots to divide the clump.
Once you have all your micro divisions separated, you’re ready to plant!
Planting Geum Divisions
Geum will grow best in well-drained soil that receives full to part sun. Space plants 12-18” apart for cut flower production, or as close at 9” if you’ll be dividing frequently.
Bury the new divisions so the roots and rhizomes are completely underground, with the crown just below the surface. Green shoots and top growth should be left exposed.
When to Divide Geum
Remember to divide Geum every few years, in spring or fall, to keep them healthy and productive.
