Because they look so similar, hardy geranium is a term that botanists use to distinguish geraniums from pelargoniums. You may see hardy geraniums called cranesbills at your local gardening center. The hardy geranium is a perennial flowering plant that is more cold-tolerant than the pelargonium, so if you live in an area with cold temperatures it is important to distinguish between the two when you go to purchase your plants.
Things You’ll Need
- 10-10-10 fertilizer
- Pruning shears
- Provide the hardy geranium well-drained soil in a sunny to partially shady location. If you live in an area with hot summer sun, provide the hardy geranium some afternoon shade.
- Water the geranium when the soil is dry during cool weather, but keep the soil slightly moist when the weather is hot. Check the soil frequently during periods of dry or windy weather as it will dry out quicker. Overwatered hardy geraniums are subject to root rot which may be controlled with a fungicide that contains terrachlor.
- Fertilize the hardy geranium in the spring using a 10-10-10 formula, at the rate suggested on the product’s label.
- Cut off dead stems and flowers periodically throughout the growing season. Cut the entire plant back to 6 inches in height in late summer.
