For easy planting and no-maintenance growing, you can’t do much better than wildflowers. Bluebells, hardy from growing zones 2 to 8, can be grown almost anywhere. And all they need is a bit of sun and well-drained soil to thrive. After they have established themselves, their clusters of blue blossoms will appear each spring with no upkeep or attention. In fact, bluebells are so hardy, that if completely forgotten about, they may overrun other plants in your garden or even spread into the yard.
Spread 4 inches of organic compost over the planting bed. Then, use a garden hoe to loosen and turn the soil to a depth of 6 inches. Mix in the compost as you go.
Plant your bluebell bulbs in the summer. Use a trowel to dig a hole for each bulb that is 5 inches deep. Place the bluebell bulb in the hole with the flat end down and the pointed end facing up. Dig holes for neighboring bulbs at least 4 inches away. Cover the bluebells with soil and tamp it down with your hands.
Water the bluebell bulbs well enough to thoroughly soak the ground. Afterwards, keep the soil moist with regular light watering twice a week until your bluebell flowers bloom in spring. Water your bluebells only in case of severe drought.
