Sunlight:
Mexican marigold thrives in environments with plenty of sunlight and should be placed under full sun. They need at least 6 hours of direct sunlight daily. Good sunlight conditions help reduce pests and diseases, significantly improving flower quality.

 Soil:

Mexican marigold does not have high soil requirements. They grow better in less fertile soils and do not need a culture medium rich in organic matter. Water appropriately when the soil is dry to help the plants thrive.

Care Guide

Planting:
Mexican marigold can be sown annually. The ideal ambient temperature for sowing is above 59°F, and it can be done in spring and summer. Outdoor direct sowing is recommended, as the seeds germinate quickly. Since they won't grow until the weather warms up, the growth rate of directly sown plants is comparable to those started in indoor pots. The seeds are large and easy to sow. Cover the seeds with soil and water after sowing; small seedlings will sprout within a week. Many nurseries cultivate seedlings, so if you prefer not to sow seeds, you can buy seedlings to save time and effort.

Water

During planting, ensure regular watering. Avoid letting the soil stay dry for extended periods. In extremely sunny conditions, daily watering may be necessary. Once Mexican marigolds develop well-established root systems, they become drought-tolerant and do not need frequent watering. However, watering them once a week is recommended for bright and colorful flowers. Adjust the watering time and amount based on environmental conditions, avoiding water accumulation to prevent root rot. In very hot weather, spray newly sprouted seedlings with water to keep the soil moist.

Fertilizer

Mexican marigold is highly adaptable and generally requires no additional fertilizer unless the soil is very barren. To extend the blooming period, apply topdressing when the plants bloom in summer to increase the number of flowers. Use a special fertilizer for Compositae plants in the evening. In the 15 days leading up to blooming, this special fertilizer can be diluted and added to the soil to store the necessary nutrients for blooming and prolong the blooming period. After blooming, you can also spray a 0.5% solution of monopotassium phosphate (MKP) on the leaf surfaces.

Pruning

Mexican marigold continues to bloom throughout the entire summer. To maintain this state, regularly prune withered flowers.

Harvest

Mexican marigold can be used as cut flowers and starts blooming in early summer. They have a long blooming period, reaching full bloom in midsummer and lasting through autumn with proper care. Avoid premature harvest, as picked flowers do not easily bloom. It is best to harvest them 1-2 days before blooming, when there are 4-6 petals on a flower bud gradually opening up.

Seasonal Precautions

Mexican marigold has a long blooming period. To ensure continuous blooms throughout the summer, regularly prune withered flowers. Be vigilant for signs of disease, as these plants are susceptible to powdery mildew in humid and rainy summers.

In late summer, when nighttime temperatures drop below 40°F, the above-ground parts of the plant will begin to wither. Once the above-ground parts are completely dead, use clean scissors to cut off and remove the dead branches to prevent pests and diseases from overwintering.

Common Problems

Why is the blooming period so short?

• Untimely Pruning:
  Not pruning withered flowers regularly can affect the blooming period. Prune withered flowers to prevent nutrient consumption and promote the germination of new flowers.

• Lack of Topdressing:
  Ensure topdressing is carried out as needed to provide essential nutrients and extend the blooming period.

• High Temperatures:
  High temperatures can shorten the blooming period. For potted Mexican marigolds, move them to a shady place with good ventilation to help prolong blooming.

Regular care and adjustments can help maintain a longer blooming period for your Mexican marigolds.

Conclusion

Mexican marigolds are an excellent choice for gardeners of all skill levels due to their hardiness, ease of care, and long blooming period. By ensuring they receive sufficient sunlight, appropriate watering, and occasional fertilization, you can enjoy vibrant and long-lasting blooms. Regular pruning and attention to seasonal changes will keep your plants healthy and flourishing.
