When to Plant Zonal Geranium?

Spring is the ideal planting time for geraniums. You'll want to wait until after your area's last hard frost. If planting in the ground, space them 6–24 inches apart. If potting in a container, don't overcrowd the space.

Does zonal geranium come back every year?

In most zones, they are grown as annuals, but in the warmest of climates they can be perennials. They are also easy to overwinter. For example, you can bring containers indoors to care for them during the winter months.

When can I plant geranium plants outside?

Medium-sized geraniums should be grown on for 2 – 4 weeks before planting out, large-sized geraniums can be planted straight out as long as the risk of frost has passed. Ensure plants have been well watered.
