These plants are not frosting tolerant, despite their hardiness. They shouldn’t be sowed or planted outside until the risk of frost has passed. In the spring, sow seeds straight into the garden once the soil has warmed up.

Seeds can be started indoors, but they germinate so quickly outside that there’s no point. You can start cultivating marigold seeds six to eight weeks before the last frost date if you reside in a location with a late last frost date. Once the soil is warm—above 40°F—seedlings will be ready to sow. In warm weather, these plants sprout in approximately a week, and plants produce blooms in around eight weeks.

Add a bit of granular fertilizer to the planting hole if the soil is nutrient-deficient.

A 5-10-5 will suffice. Sow marigold seeds approximately one inch apart in moistened soil. Apply a thin layer of dirt on top. Thin the seedlings while they are still little. Try to put 8 to 10 inches between French and signet types. The larger African marigolds should be spaced apart by at least 10 to 12 inches. Use a soil-based potting mix when growing in pots.

Tag the envelope with the contents and the date harvested, so you remember what’s inside. At the end of the day, all you have to do is to make sure it doesn’t have a lot of humidity or temperature fluctuations. Wet seeds can rot, mold, or sprout, so keep them dry.
