Marigold may be grown from seed sown early indoors and transplanted outside after frost, or sown directly in the garden after frost, or from potted plants.

Sowing Seed Indoors:

  • Sow indoors 4-6 weeks before the last frost using a seed starting kit
  • Sow seeds ¼ inch deep in seed starting soil
  • Keep the soil moist at 70-75 degrees
  • Seedlings emerge in 7-14 days
  • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
  • Thin to one seedling per cell when they have two sets of leaves.
  • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
  • Transplant hardened-off seedlings to the garden after the frost.
  • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning.  This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

Sowing Directly in the Garden

  • Direct sow seeds in average soil in full sun after all danger of frost. In frost free areas, sow from fall to early spring. In the Deep South, a spot that receives shade during the afternoon helps protect plants from excessive heat. 
  • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones. 
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Sow seeds about 6 inches apart and cover with ¼ inch of fine soil.
  • Firm soil lightly, water and keep evenly moist.
  • Seedlings emerge in 7-14 days.
  • Thin plants to stand 9-12 inches when seedlings are 1 inch high.

Planting Potted Plants:

  • Select a location in full sun with good rich, moist, well drained organic soil. In the deep South, a spot that receives shade during the afternoon helps protect plants from excessive heat. 
  • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones. 
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Set level with the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand leaving a slight depression around the plant to hold water.
  • Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
  • Use the plant tag as a location marker.
  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
  • Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
  • Keep plants well-watered during the growing season, especially during dry spells. Watering during dry spells will improve flowering--although it will produce lots of succulent leaves.
  • Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.
  • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Flower-tone, as higher rates may encourage root rots.
  • Deadhead marigolds to keep them flowering from late spring until frost.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Remove plants after they are killed by frost in fall to avoid disease issues the following year.
  • Add marigolds to sunny beds, borders and containers. Plant marigolds with both sun-loving annuals and perennials in your garden. Marigolds combine well with lavenders, salvias or sages, cosmos, daylilies, coreopsis, and nasturtium. 
  • Marigolds are frequently planted among vegetable crops to prevent pest and disease problems. 
  • Many shorter marigold varieties are great for containers.

Marigold, Nema-Gone is rated 4.5556 out of 5 by 9.
Rated 5 out of 5 by from big, vigorous, pretty and fragrant! I've become a big fan of these marigolds. I can't tell if they're doing anything to nematodes, but they certainly grow well in my garden and look lovely. I only planted a small amount of seeds from the packet, and it seems like all or most germinated. They've grown into very large plants, like shrubs, some two or three feet tall (as seen pictured with my cat.) I'm not entirely sure if all the seeds in the packet were actually for the same Nema-Gone type or not, since the blooms are all so varied (see picture). Some are yellow like the Burpee picture here, some are orange, and some are reddish. Nevertheless, they're all pretty and all growing well. They have nice long stems for bouquets, they smell sweet, and bees and butterflies seem to like them.

Rated 5 out of 5 by from Enormous! I tried this in my new garden. You really need some space for this monster. It produces what I would call a large shrub. Beautiful and hundreds of flowers,all the way into November. If I had more open space I would certainly plant again.

Rated 1 out of 5 by from Not one plant I have had no luck getting any of the seeds to actually grow into a mature plant. I direct sowed seeds in spring and not a single one sprouted. I then tried starting some indoors. A few sprouted, I hardened them off and ended up with 2 plants out of 8 to 10 pots. Plants died within 1 week. I am very disappointed as I know I have nematodes in my vegetable garden. Had to give it 1 star but would have given it no stars.

Rated 5 out of 5 by from Excellent Garden Companion! We don't have nematodes, but I was curious if it had any above-ground pest repelling qualities. I now regularly plant in corners and gaps in the vegetable garden, and my anecdotal conclusion is that it does repel pests. It's a beautiful marigold, but be warned that the plant grows quite large.

Rated 5 out of 5 by from Plant and run! I planted these marigolds for the nematode problem, I never imagined they would grow so big. I had a hedge across the front yard, then several toppeled over the retaining wall and formed a waterfall effect which was beautiful. I planted one plant at the bottom of our driveway and just recently cut it down. It was 8 ft wide, 6 ft long, and 4 ft high. All the neighbors couldn't believe that was just one plant. I will use them as a cover crop in my garden, they suppress weeds too!

Rated 5 out of 5 by from Wow! This was the first year planting anything here. Wasn't sure if anything would grow in a heavy clay mix. Did these marigolds ever grow! The ones closest to my kitchen window were over 6' tall. Loads of blooms all summer, and even now after 2 light frosts I still have flowers and lots of greenery. I direct sowed and then just let them go naturally. These are hardy little flowers that can take the elements full force without blinking an eye. I look forward to growing them next year.

Rated 5 out of 5 by from Required for organic For years I have fought off white flies, caterpillars, and japanese beatles, to name a few. Three years ago, I started planting these marigolds between rows of vegetables and the pest count is way down. Soil pests are almost completely eliminated. It won't keep away slugs, snails and such, but the soil and airborn pests seem to hate this wonderful little flower. These plants grow tall and will shade some heat-loving vegetables, so don't plant too close to low growing heat-lovers. Great for planting around lettuce and other vegetables that actually like a little shade from the mid-day sun. Stop spraying. Plant marigolds!
