Growing Geranium from Seeds in Pots

Growing Geranium from Seeds in Pots

Geraniums, with their vibrant blooms and lush foliage, are a favorite among gardeners. They are versatile, thriving in both garden beds and pots. Here’s a detailed guide on how to grow geraniums from seeds in pots12.

1. Gather Your Supplies

You’ll need geranium seeds, a seed tray, pots, soil, and fertilizer1. Geraniums grow best in a seed starting mix, and they will germinate most successfully between 70°F and 75°F1.

2. Fill the Seed Tray with Soil

Fill a seed tray with moistened potting soil, ideally a seed starting mix1. Make sure each cell in the seed tray is no larger than two inches1.

3. Sow the Seeds

Place one seed in each section of the tray, and cover each seed with just a thin layer of the seed starting soil1. Cover the tray with plastic wrap to create the right environment for germination1.

4. Place the Seed Tray in a Warm, Sunny Spot

Geraniums germinate in an environment that is 72 °Fahrenheit with consistent moisture1. This can be achieved with the combination of the covered tray and a sunny window, though you can also place the tray under a plant lamp to keep it at the right temperature1.

5. Keep the Soil Moist

Geraniums need consistent soil moisture1. If the soil begins to dry out, add moisture back in1.

6. Look Out for Germination

Germination estimates for geraniums vary. It could be as quick as just a few days or it could take up to a month1. Continue to monitor the seedlings in the seed tray while they grow, allowing them to stay there until they have two true sets of leaves1.

7. Move the Plants from Seed Trays to Pots

Once the seedlings have two true sets of leaves, they can be moved from the seed trays to pots1.

8. Fertilize the Young Plants

Fertilize the young plants to help them grow1.

9. Move the Plants Outdoors

Once the weather is warm enough, the plants can be moved outdoors1.

Chart: Geranium Seedling Care Timeline

Stage Days Tasks
Germination 7-14 Maintain consistent moisture and warmth (around 70°F). Provide bright, indirect sunlight.
Seedling Development 4-6 weeks Once seedlings have two sets of true leaves, thin to one plant per pot. Gradually introduce them to cooler temperatures and more direct sunlight.
Potting Up 6-8 weeks Transplant seedlings into larger pots with fresh potting mix. Pinch back the growing tips to encourage bushier growth.
Hardening Off 1-2 weeks Gradually acclimate seedlings to outdoor conditions before placing them permanently in their final location.
Blooming 12-16 weeks from sowing Enjoy your flourishing geraniums! Deadhead spent flowers to encourage continued blooming.

Unveiling the Geranium Seed Journey

Now, let’s delve into each step of this exciting process:

  1. Gearing Up:
  • Seeds: Choose high-quality geranium seeds from a reputable source. Varieties come in a dazzling array of colors, from classic reds and pinks to vibrant oranges and purples. Select varieties suited to your climate and desired pot size. Dwarf varieties are ideal for container gardening.
  • Containers: Select pots with drainage holes. The size will depend on the mature size of your chosen geranium variety. Opt for individual pots or larger containers for a mixed display.
  • Potting Mix: Use a well-draining, seed-starting mix. Look for a lightweight formula specifically designed for seedlings.
  • Light and Temperature: Geraniums require warmth for germination. Aim for a location with consistent temperatures around 70°F (21°C) with bright, indirect sunlight. A heat mat can be helpful in maintaining optimal temperatures.
  1. Planting the Seeds:
  • Moisten the potting mix: Fill your pots with the seed-starting mix and moisten it thoroughly.
  • Sowing the Seeds: Gently sow the seeds on the surface of the mix, spacing them according to the packet instructions. Most geranium seeds are small and don’t require covering with soil.
  • Light and Moisture Management: Lightly mist the surface to settle the seeds and create a humid environment. Cover the pots with clear plastic wrap or a humidity dome to retain moisture. Place the pots in the warm, well-lit location.
  1. Sprouting and Seedling Care:
  • Germination Magic: Be patient! Germination typically occurs within 7-14 days. Maintain consistent moisture by misting the surface of the soil as needed. Avoid overwatering, which can lead to rot.
  • Light Up Their Lives: Once seedlings emerge, remove the plastic wrap and provide them with bright, indirect sunlight for 14-16 hours a day. You can use a grow light to supplement natural light if needed.
  • Thinning the Ranks: Once seedlings have two sets of true leaves (not the initial cotyledons), it’s time to thin. Gently pinch or snip off the weaker seedlings, leaving one healthy plant per pot.
  1. Potting Up and Growth Encouragement:
  • Moving Up in the World: After 6-8 weeks, when seedlings have reached 3-4 inches tall, transplant them into larger pots filled with fresh potting mix. Choose pots appropriate for the mature size of your geranium variety.
  • Pinching for Perfection: To encourage bushier growth and more flower production, pinch back the growing tips once seedlings reach 6 inches tall. This will stimulate lateral branching.
  1. Hardening Off and the Great Outdoors:
  • A Gradual Introduction: Before placing your geraniums in their permanent outdoor location, they need to be acclimated to cooler temperatures and stronger sunlight. Gradually expose them to outdoor conditions for a week or two, starting with a few hours a day in a protected location and gradually increasing the duration and intensity of sunlight exposure.
  1. Blooming Beauty and Care:
  • Floral Extravaganza: Within 12-16 weeks from sowing, your geraniums should begin to reward you with a dazzling display of blooms!
