Prepare a sunny patch of soil for your Anemone blanda plants. Break up the soil with a pitchfork to a depth of 6 inches. Soak the Anemone blanda tubers overnight in medium pot of lukewarm water the evening before planting.
Bury the tubers 2 to 3 inches under the soil line. Use a small hand shovel to dig the planting hole and deposit one tuber, nose up, in the hole. Pat the soil over the top to remove air pockets. Space each tuber two to three inches from the next.
Water the soil generously, drenching to a depth of 1 inch with a garden hose. Keep the soil moist throughout the duration of the growing season with a mix of rain and supplemental watering.
Cover the soil surrounding the Grecian windflowers with a light, 3-inch layer of bark mulch. Mulching improves drainage and protects the tubers from extreme temperatures.
Cut back the foliage after it dies back naturally and turns brown. This can be done by mowing over the foliage with a lawn mower or cutting it to the soil line with a pair of sharp pruning shears. The bulbs will reemerge the following spring without assistance.
