2. Choosing and Buying French Marigold Seeds

We have a large selection in our store at Gardeners Basics. You may find different varieties: double, singles, and the smaller signet marigold. Choose the type that best suits your flower garden.
3. Starting Seeds Indoors
To give your French marigolds seeds a head start, sow seeds indoors 6-8 weeks before the danger of frost has passed. This gives your plants enough time to grow strong before transplanting outdoors.
How to Sow Seeds Indoors
- Fill seed trays or small pots with well-draining soil mixes, such as peat moss, vermiculite, and perlite.
- Sow the French marigold seeds by placing them 1/4 inch deep in the soil, and covering them lightly.
- Water the soil gently to avoid dislodging the seeds.
- Place the seed trays or pots in a warm, well-lit area, maintaining a temperature of 65-75°F (18-24°C).
- Keep the soil moist but not soggy to prevent fungal diseases.
- After 7-14 days, you should see the seeds germinate, and seedlings emerge.
4. Transplanting Seedlings Outdoors
Once the danger of frost has passed and your seedlings are at least 2 inches tall, you can transplant them into your flower bed or containers.
How to Transplant Seedlings
- Prepare the planting area by loosening the soil and removing weeds or debris.
- Dig holes approximately 8-12 inches apart, depending on the variety and your desired plant density.
- Carefully remove the seedlings from their trays or not damage the roots.
- Place each seedling in a hole, ensuring the root ball is covered with soil.
- Water the transplanted seedlings thoroughly to help them establish themselves in their new environment.
5. Direct Sowing French Marigold Seeds
If you prefer to direct sow your French marigold seeds outdoors, wait until the danger of frost has passed and the soil has warmed up.
How to Direct Sow Seeds
- Prepare the planting area by loosening the soil and removing weeds or debris.
- Sow the seeds 1/4 inch deep and 8-12 inches apart, depending on the variety and your desired plant density.
