What are Geraniums?
First, a quick note: What we usually call “geraniums” are actually Pelargoniums. True geraniums are a different plant. But don’t worry – we’ll stick with calling them geraniums since that’s what most people know them as.
Geraniums come in many colors like red, pink, white and purple. They have rounded leaves that are often fragrant when touched.

How to Plant Geraniums
When to Plant:
Plant geraniums in spring after the last frost. To find out when that is in your area, use the USDA Plant Hardiness Zone Map.
Where to Plant:
Geraniums like lots of sun. Choose a spot that gets at least 6 hours of direct sunlight daily.
Soil:
These plants like well-draining soil. If planting in pots, use a good potting mix. Learn more about container gardening from the University of Illinois Extension.
Planting Steps:
- Dig a hole as deep as the plant’s container and a bit wider
- Place the plant in the hole at the same depth it was in its pot
- Fill with soil and water well
Caring for Your Geraniums
Water:
Water geraniums when the top inch of soil feels dry. Don’t let them sit in water.
Fertilizer:
Feed geraniums every 2 weeks during the growing season with a balanced, water-soluble fertilizer.
Pruning:
Pinch off dead flowers and yellow leaves to keep plants tidy and encourage more blooms.
Winter Care:
In cold areas, bring potted geraniums indoors before frost. In warm areas, they can stay outside all year.
Common Problems and Solutions
