When to plant:
Sow seeds indoors 10 weeks before last frost. Plant seedlings outdoors in spring after all threat of frost has passed. Container-grown transplants are best planted in spring.
Where to plant:
Plant geraniums in an area that will get at least 6 hours of sun a day, in fertile, well-draining soil.
How to plant:
For potted plants, place seedlings in 4-inch containers and move up to larger pots as they grow. Plant in-ground geraniums with 6 to 24 inches between them, depending on their growth habit; don’t overcrowd them.
