A dark lord geranium is a geranium variety with dark purple and green foliage that reaches a height between 8 and 10 inches. Its flowers are also purple, and bloom during the summer months. The dark lord geranium is typically grown in USDA plant hardiness zones 4 to 8 and should be planted in an area that receives at least six hours of sunlight, but with some shade in the afternoon. The dark lord geranium is planted and cared for like all other geraniums.
Test the soil 2 inches deep to see if it is dry. Do this with your finger or with a soil moisture meter available at most home and garden centers.
Water your in-ground dark lord geraniums with about an inch of water if the soil tested dry. Water at the base of the plants whenever possible, especially while they are in bloom.
Water your potted dark lord geraniums slowly at the base of the plants if the soil was dry. Water until the excess begins to drain out of the bottom holes. If you have saucers under the plant pots, dump out any excess water.
