Green Thumb Guide

Plant bulbs in well draining soil along with a sprinkle bulb fertilizer. Should be planted one bulb per square foot at a one inch depth. Deadhead spent flowers to encourage new blooms. Cut foliage back after it turns yellow. Bulbs can either be left to spread naturally or dug up and divided by hand. Store bulbs in a dark, dry, cool place until ready for planting.
