Growing Geraniums from Seed Tip
To grow geraniums from seed, sow seeds in early to mid-February indoors, using a seed-starting mix, and maintain a warm, moist environment before gradually acclimate seedlings to outdoor conditions. Below are a few important points or tips for achieving germination and happy new seedlings.
- Use plastic wrap or a clear plastic dome to maintain humidity during germination. The dome lid containers worked amazing for me early on.
- Ensure the seed-starting mix is thoroughly moistened before planting and during the germination process. However, be sure the soil isn’t soggy or bogged down.
- Geranium seeds need warmth (70-75°F) to germinate so I use a seed heat mat indoors to begin the germination process.
- Germination of geranium seeds can take anywhere from a few days to a few weeks. Mine took about 14 days.
- Ensure seedlings receive ample light, either from a sunny window or grow lights.
- Once the seedlings get their true leaves they can be transplanted to bigger container.
- Geranium seedlings can be slow-growing, so be patient.

I love this! I have never started my geraniums from seed. I always winter over in the greenhouse and take cuttings in spring. It is a great way to get more of a color you like.
Thank you for commenting on my website blog! I am excited to see this variety when it blooms. The geranium seeds were super easy to germinate and grow. Happy Spring.
