I will be dividing my hostas this fall. I have several plants that are growing along the east side of my house. Last spring I built a block patio and have now decided to put hostas around the edges. Hostas grow into clumps that can easily be divided. I have had success dividing them in the spring or the fall. In just a couple of years, each plant has increased to a nice full clump.
There are so many kinds of hostas. I mostly have the larger plants, as they make such a nice spread around the foundation on the east side of the house. Also, they grow with such thick foliage weeds seldom have a chance to grow among them.
Hostas have leaves that are heavily veined or puckered. They have leaf colors that are emerald green, blue-gray, cream, yellow and in many variegated patterns. Hostas form lush clumps that vary in size from dwarf to knee-high. Many types produce lilylike flowers that can be lavender, purple, or white, blooming in mid to late summer. Hosta foliage are eye-catching and last the entire growing season. Plants grow 6 inches to 3 feet tall and wide.
Hostas combine well with fine-textured plants such as ferns and astilbes. They grow best in light to full shade. There are plants now that grow in sunlight, but I haven't tried them. They like fertile, humus-rich, moist soil, but tolerate average conditions. I find they require little care and even though this was a very hot, dry summer, I didn't water them often.
