Hardy Geraniums are easy to grow and will tolerate sun or shade in a moist, but well-drained soil. They are not too fussy on the type of soil, but will not do well in waterlogged conditions. Water at least once a week until established, especially during the summer months. It will also be beneficial to feed once a month with a liquid plant food such as Miracle Gro or another similar option. Remove faded flowers and foliage to encourage fresh growth and further flowering throughout the season. Lift and divide large, congested clumps in the spring.
