How to Grow Geraniums: A Complete Guide
Introduction
Geraniums, also known as pelargoniums, are popular and easy-to-grow plants that add a burst of color to any garden or home. With their beautiful flowers and fragrant leaves, geraniums are a versatile plant that can be grown in a variety of ways.
Growing Conditions
Geraniums prefer moist but well-drained soil and full sun. They can also be grown in partial shade, but they may not bloom as profusely. Geraniums are hardy in USDA plant hardiness zones 10-11, but they can be overwintered indoors in colder climates.
Planting Geraniums
When planting geraniums, choose a location that receives plenty of sunlight and has well-drained soil. Dig a hole that is twice the width of the root ball and just as deep. Place the geranium in the hole and backfill with soil, tamping down gently to remove any air pockets. Water the geranium deeply after planting.
Care and Maintenance
Geraniums are relatively low-maintenance plants, but they do require some basic care to thrive. Water geraniums regularly, especially during hot weather. Deadhead spent flowers to encourage new growth and blooming. Fertilize geraniums monthly with a balanced fertilizer.
Overwintering Geraniums
In colder climates, geraniums must be overwintered indoors to protect them from frost. Dig up geraniums before the first frost and pot them up in a peat-based potting mix. Place the pots in a cool, dark location and water them sparingly over the winter. In the spring, gradually increase watering and move the geraniums to a brighter location to encourage new growth.
Propagation
Geraniums can be easily propagated by taking stem cuttings. Take cuttings from healthy, non-flowering stems in the spring or summer. Remove the lower leaves from the cuttings and dip the ends in rooting hormone. Plant the cuttings in a peat-based potting mix and keep them moist. Geranium cuttings will typically root within 4-6 weeks.
Troubleshooting
Geraniums are generally pest- and disease-free, but they can occasionally be affected by problems such as aphids, whiteflies, and rust. Treat infestations promptly with an appropriate insecticide or fungicide.
Popular Geranium Varieties
There are many different varieties of geraniums available, each with its own unique characteristics. Some popular varieties include:
