What To Know
- The optimal time to harvest geranium seeds is when the seed pods have fully matured and turned brown.
- Place the seed pods in a paper bag or envelope and store them in a warm, dry location for several weeks.
- After the seed pods have dried, gently crush them between your fingers or use a mortar and pestle to extract the seeds.
Geraniums, beloved for their vibrant blooms and aromatic foliage, are a staple in many gardens. While you can purchase geranium seeds from nurseries, harvesting your own seeds is a rewarding and cost-effective way to propagate these beautiful plants. This guide will provide you with step-by-step instructions on how to get geranium seeds from plant, ensuring successful seed production and germination.
Identifying Seed-Producing Geraniums
Not all geraniums produce viable seeds. The most common geranium species that yield seeds include:
- Pelargonium grandiflorum (Grand Geraniums)
- Pelargonium peltatum (Ivy Geraniums)
- Pelargonium zonale (Zonal Geraniums)
When to Harvest Geranium Seeds
The optimal time to harvest geranium seeds is when the seed pods have fully matured and turned brown. This typically occurs in late summer or early fall. Avoid harvesting seeds from immature pods, as they may not be viable.
How to Harvest Geranium Seeds
1. Collect Mature Seed Pods: Once the seed pods have turned brown, carefully remove them from the plant. Handle them gently to prevent damage.
2. Dry and Store Seed Pods: Place the seed pods in a paper bag or envelope and store them in a warm, dry location for several weeks. This will allow them to fully dry and release their seeds.
3. Extract Seeds: After the seed pods have dried, gently crush them between your fingers or use a mortar and pestle to extract the seeds. Remove any debris or chaff from the seeds.
Storing Geranium Seeds
Store geranium seeds in a cool, dry place away from sunlight. Use airtight containers or envelopes to prevent moisture and pests from damaging the seeds. Properly stored seeds can remain viable for up to three years.
Sowing Geranium Seeds
1. Start Indoors: Start geranium seeds indoors 6-8 weeks before the last frost. Fill seed trays with a well-draining potting mix and sow the seeds on the surface. Gently press them into the soil but do not cover them.
2. Provide Warmth and Light: Place the seed trays in a warm location with temperatures between 70-75°F (21-24°C). Provide plenty of bright, indirect light.
3. Keep Moist: Keep the soil consistently moist but not soggy. Use a spray bottle or bottom-water the seed trays to prevent overwatering.
4. Transplant Outdoors: Once the seedlings have developed their first set of true leaves, transplant them outdoors into well-drained soil. Harden them off gradually by exposing them to outdoor conditions for increasing periods.
Troubleshooting Seed Production
- No Seed Production: Ensure that you are growing a seed-producing geranium variety and that the plants are receiving adequate sunlight and nutrients.
- Immature Seed Pods: Allow the seed pods to mature fully before harvesting. Avoid harvesting green or immature pods.
- Poor Germination: Check the age of the seeds and ensure they are stored properly. Old or improperly stored seeds may have low germination rates.
Key Points: The Joy of Seed Harvesting
Harvesting geranium seeds from plant is a fulfilling experience that allows you to propagate your favorite varieties and share the beauty of geraniums with others. By following these step-by-step instructions, you can successfully collect, store, and sow geranium seeds, ensuring the continuation of these beloved plants in your garden for years to come.
