Marigold

Seed types:
French Marigold Seeds - small marigolds - 6-12 in African Marigold Seeds - tall marigolds - up to 3-5 feet Marigolds are great companion plants that will protect your garden from many pests. Utilize them around your potato plants as they provide benefit both to the top of the plant AS WELL as the roots and tubers below!
•Marigolds need lots of sunshine.
•Though they grow in almost any soil, marigolds thrive in moderately fertile, well-drained soil.
•Sow them directly into the garden once the soil is warm, or start seeds indoors about a month to 6 weeks before the last spring-frost date.
•The seeds germinate easily, but watch out for damping off if you start them inside.
•Separate seedlings when they are about 2 inches tall. Plant them in flats of loose soil, or transplant them into the garden. •Space tall marigolds 2 to 3 feet apart; lower-growing ones about a foot apart.
•If planting in containers, use a soil-based potting mix. •Germination from large, easily handled seeds is rapid, and blooms should appear within a few weeks of sowing.
•If the spent blossoms are deadheaded, the plants will continue to bloom profusely.
•When you water marigolds, allow the soil to dry somewhat between watering, then water well, then repeat the process. •Do not water marigolds from overhead. Water at the base of the plant.
•Do not fertilize marigolds. Too rich a diet stimulates lush foliage at the expense of flowers. Marigolds bloom better and more profusely in poor soil.
•The densely double flower heads of the African marigolds tend to rot in wet weather.
If planting around potatoes, wait until the potatoes are near ground level or your container is full to avoid disturbing the seedlings. Marigolds will grow quickly, so thin as needed. If handled carefully, they can be transplanted elsewhere and will bloom through the summer.
