Life Cycle This refers to whether a plant is an annual, biennial or perennial. Annuals complete their life cycles in one year; biennials produce foliage the first year and bloom and go to seed the second year; perennials can live for more than two years.

Annual

Sow Method This refers to whether the seed should be sown early indoors and the seedlings transplanted outside later, or if the seed should be sown directly in the garden at the recommended planting time.

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, Key Lime is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from GORGEOUS BLOOMS Beautiful, gorgeous blooms all summer long. Love, love, love the color. Plants grew every bit of three feet tall, and very vigorous. I planted them 10-12 inches apart, which was too close; I'd give them more room. Long stems made for GREAT bouquets that were also long-lasting in the vase. Only issue was that the plants were very top heavy and fell over; I staked them with tomato stakes and tied up the branches. Had to tie up more branches thru the season to keep them from covering other lower plants in front of them. I have to rate them only 4 stars because of this issue, but in all other categories definitely a 5.
