How to Divide Hosta Bulbs


Hosta plants are shade loving plants, rich in foliage that may be a variety of different hues and styles. Once you have had hosta plants growing in a shady growing area for several years, it will become obvious when you need to divide them. As the centers of mature hosta plants begin looking bare, make plans to divide the hosta plants in late summer. By dividing hosta bulbs in the last third of summer, you give the newly divided plants time to recover and rejuvenate before winter cold sets in.

Step 1

Watch your hosta plants for indications that you must divide them. When you find a mature hosta plant with an undeveloped area in the center of the plant, it is time to divide this hosta.

Step 2

Dig up the entire hosta plant carefully with the shovel. Shake off the excess soil and use the garden hose to rinse off as much soil as possible from the bulb.

Step 3

Use the utility knife to cut the hosta bulb apart. Make sure each division of the hosta bulb has an equal number of stems growing from the bulbs.

Step 4

Replant the hosta bulbs in new planting locations, digging each hole 1.5 times wider than the size of the mature hosta plant you just divided and deep enough so the hosta plant will be at the same depth as it was previously. Space large hosta plants 3 feet apart. Space medium hosta plants 2 feet apart. Space small hosta plants 12 to 18 inches apart.

Step 5

Water the newly divided and planted hostas generously immediately after planting them. Keep the hosta plants evenly moist during the first two weeks after dividing to give them a strong start.
