How to Grow Marigold from Seeds

Marigolds, scientifically known as Tagetes erecta, are beautiful and vibrant flowers that can easily be grown from seed. Follow these detailed steps to successfully grow marigolds from seed.

Choose the Right Seeds

Start by selecting high-quality marigold seeds from a reputable supplier, such as right here, at Aussie Hydro. Look for seeds that are plump, firm, and free from any signs of damage or decay.

Prepare the Soil

Marigolds thrive in well-draining soil with a pH level between 6.0 and 7.0. Prepare the soil by loosening it to a depth of 6-8 inches and adding organic matter, such as compost, to improve fertility.

Sow the Seeds

Plant the marigold seeds directly into the prepared soil after the last frost date in your area. Sow the seeds 1/8 inch deep and space them 6-8 inches apart to allow room for growth.

Provide Adequate Water and Sunlight

Water the newly planted seeds gently to keep the soil moist but not waterlogged. Marigolds require full sunlight to thrive, so make sure they receive at least 6-8 hours of sunlight per day.

Thin and Transplant Seedlings

Once the seedlings have grown to a height of 2-3 inches, thin them out to allow the strongest plants to thrive. Transplant any excess seedlings to another location or container.

Protect from Pests and Diseases

Keep an eye out for common pests, such as aphids and spider mites, that may damage your marigold plants. Use organic pest control methods to protect your plants from infestations.

Deadhead Spent Flowers

To encourage continuous blooming, deadhead any spent flowers by pinching them off at the base. This will redirect the plant's energy into producing new blooms.

By following these steps, you can successfully grow marigolds from seed and enjoy their vibrant colors and cheerful blooms in your garden.
