Geranium is an annual plant that can be grown in Zones 3 to 9.
Plant geraniums after winter’s last frost because they are not cold-hardy. In warmer climate areas of North America, they can be grown outside all year long.
Bloom Season: First bloom is generally from April to May. Geranium can be cut back after the first bloom to produce more flowers from early summer into fall.
Bloom Color: Depending on the species, Geranium flowers come in a wide variety of colors. Classic varieties bloom white, pink, red, burgundy, orange, and purple flowers.
Plant height can range from 6 inches to several feet of flowers.
At 4 inches in a pot, transfer geranium to the garden.
With enough space, garden geranium can grow to be 18 inches tall and wide.
When planted in the garden, geranium does well in loose soil with organic matter. Potted plants need plenty of drainage holes to prevent root rot. Soil should not be left soggy.
Sun or Shade: Requires sun with some shade. Geranium does best with morning sun and afternoon shade, but at least 4 to 6 hours of sun. In climates with hot summers, shade is necessary.
