Marigolds growing in containers should be watered daily as containers dry out quickly. To save seeds, allow the flowerheads to fade and dry intact on the plant. When fully dried, remove the petals and shake out the seeds. Not all flowerheads will produce seeds, but most should. Remember that hybrids will not come true from saved seed. Marigolds can be susceptible to gray mold, bacterial leaf spot, powdery mildew and root rot. Pests such as leaf miners or spider mites may also be a problem.
Interestingly enough, marigolds also do their fair share of repelling several types of insects. According to the New York Botanical Garden, marigolds can help keep away mosquitoes, aphids , thrips, whiteflies , Mexican bean beetles, squash bugs, tomato hornworms and nematodes.
Tip from Park Seed : Try sowing some 'Fireball' seeds every 2 weeks for a month or more for a mix of colors as the flowers mature. Growing marigolds in or next to your vegetable garden can prove to be quite beneficial in many ways. If you are growing an organic vegetable garden, it is best to purchase organic marigold seeds and grow them yourself rather than transplanting nursery-grown or store-bought plants that may have non-organic pesticides and fertilizers in or on them.

Flower Resources Discover the right flowers for your garden. Marigolds are appropriate for seasonal use in all zones. Exposure: Full sun Bloom Time: Late spring until first frost Color: Marigolds are available in shades of orange and yellow; some with highlights of red, gold, copper or brass.
Types: There are approximately 50 species of marigold, but the 3 most common are: Tagetes patula French marigold : The most common type found in local nurseries, these range in size from 6 to 12 inches tall and 6 to 9 inches wide.
They are compact annuals with double flowerheads up to 2 inches across. Tagetes erecta African marigold : These are the tallest variety of marigolds and range in height from 1 to 4 feet, and have a 1 to 2 foot spread.
Their large flowerheads can reach up to 5 inches across, are densely double and pompon-like. Tagetes tenuifolia Signet marigold : Upright annuals that grow up to 12 inches tall and wide.
Flowerheads are single and are usually 1 inch in size. Bright and hardy marigolds are a no-fuss, low maintenance annual. Their cheery blooms thrive in the sun, making these summer-through-fall-time beauties a popular choice. Marigolds have carnation or daisy-like flowers, usually in bright orange, copper brown or yellow that can grow as single blooms or in clusters.
Their distinct smell is often described as pungent, but most gardeners appreciate this, as it keeps away garden pests and insects. However, keep an eye out for slugs and caterpillars as they can be issues for marigolds. Marigolds are easy to plant and can do well in virtually any type of soil.
Most types like full sun and can withstand even extremely hot temperatures, making them one of the easiest flowers to grow all year long.
In fact, their hardiness makes it unnecessary to start marigold seeds indoors. Below is a simple guide to planting seeds directly in the ground — or transplant — whichever you prefer. Simply cover the seeds with soil and keep them moist and warm.
If transplanting, be sure to water well after doing so. Plants will sprout in a few days if the weather is warm enough, and blooms will appear in around 2 months. Plant your marigolds in the spring, after the last frost. If you choose to start from seed indoors, you can begin the process about 2 months before the last expected frost.
Above the refrigerator is a good spot for seeds to rest if you are germinating indoors. In this case, once the seeds germinate, transplant them outdoors after the last frost.
After seeds have germinated, moisten soil and then plant seedlings about 1 inch apart from one another. If planting seeds directly in the ground without germinating, once sprouted, but while still small, thin your seedlings. Thinning seedlings is important so that maturing plants have plenty of space to grow without having to compete for nutrients and water.
It also helps improve air circulation. To thin, carefully remove a seedling and, holding it by its leaves to prevent the stem from being crushed, lightly set the roots into a hole. Pat the soil around the stem gently but firmly. Spacing will depend on the variety. Be sure to use a large enough container because marigolds tend to grow quickly, and crowding can be an issue.
Use a soil-based potting mix and either add in a granular, slow-acting fertilizer at the time of planting, or periodically water with a diluted liquid fertilizer.
Do not over-fertilize. Marigolds establish easily, and new blooms will appear not long after planting. These low-maintenance plants do not require much care, and with just a few tips, will put on a showy display for months. Tip 1. Water regularly, but not too frequently. Let soil dry out in between watering, and then water well each time. Tip 2. Never water overhead.
Too much water on marigold leaves can result in a powdery mildew building up on the pretty dark green foliage. Water at the base of the plant to avoid this. Tip 3. Deadhead as needed. Marigolds actually do not need a lot of deadheading but doing so will promote more blooms. Zingy yellows and oranges will brighten up your garden in the summer if you sow some marigolds in spring.
