Seed Geranium

Seed Geranium

The popularity of seed-grown geraniums increased because they often outperform the older geranium varieties propagated from cuttings. The new seed-grown hybrid geraniums possess excellent vigor, heat tolerance, disease resistance, and are free-blooming.  Geraniums are easy to grow from seed. However, they are rather slow growing. Sow seed in mid- to late January to produce flowering plants for spring. Flowering occurs approximately 12 to 16 weeks after sowing.   Ideal growing temperatures for geraniums are 70 to 75 degrees Fahrenheit during the day and 60 to 65 degrees Fahrenheit at night. Thoroughly water geraniums when the soil surface is dry to the touch. Fertilize weekly with a one-quarter strength houseplant fertilizer. Harden or condition the plants outdoors for seven to ten days before planting into the garden. Plant geraniums outdoors when the danger of frost has passed.
