Geraniums, known for their vibrant blooms, are a popular choice for gardeners. While often purchased as established plants, growing geraniums from seed is surprisingly straightforward – though it requires patience and the right conditions. This guide outlines the process, from seed starting to enjoying full blooms.
Why Start From Seed?
Growing from seed allows you to cultivate a wider variety of geraniums than what’s typically available at nurseries. It’s also more economical than buying mature plants, especially if you plan to grow a large number. The downside is the longer timeline: seed-started geraniums take several months to mature, so planning ahead is essential.
When to Plant Geraniums From Seed
The best time to sow geranium seeds is during the coldest months, ideally January or February. This gives the seedlings ample time to develop before the warm weather arrives. Geraniums are slow growers, and a head start ensures robust blooms when the season arrives.
Supplies You’ll Need
Before starting, gather these essentials:
- Seed Starting Mix: Provides optimal drainage and nutrients for germination.
- Seed Trays: Small cells are ideal for individual seedlings.
- Plastic Wrap: Helps maintain humidity for germination.
- Plant Lamp (Optional): Ensures consistent temperature if natural light is insufficient.
- Houseplant Fertilizer: For nourishing young plants.
Step-by-Step Growing Guide
- Prepare the Seed Tray: Fill cells in the tray with moistened seed starting mix, ensuring each is no more than two inches deep.
- Sow Seeds: Place one seed per cell and cover lightly with mix.
- Create a Germination Environment: Cover the tray with plastic wrap to retain moisture. Keep in a warm, sunny spot or under a plant lamp.
- Maintain Moisture: Geraniums need consistent moisture; check and water as needed to prevent drying out.
- Wait for Germination: Germination varies, taking anywhere from a few days to a month.
- Monitor Seedlings: Once seedlings have two true leaves, they’re ready to be transplanted.
- Transplant to Pots: Repot into individual containers with fresh soil.
- Fertilize: Feed young plants weekly with diluted houseplant fertilizer (one-quarter strength).
- Acclimate Outdoors: After the last frost, gradually introduce plants to outdoor conditions. Start in a sheltered spot before full sun exposure.
Expecting Blooms
With proper care, geraniums grown from seed will reward you with vibrant blooms by mid-spring. The flowers will continue to flourish throughout the warmer months, making your garden a colorful spectacle.
In conclusion, growing geraniums from seed is a rewarding process that requires patience, but yields beautiful results. By following these steps, even novice gardeners can enjoy homegrown geraniums for a vibrant and colorful season.
