Calendula Care
Soil Requirements
Marigold is not particularly picky about soil type, but prefers well-drained soils rich in organic matter. A soil pH between 6 and 7 is ideal for optimum growth.
Soil Preparation
Before planting marigolds, it is advisable to enrich the soil with compost or organic fertilizer to improve its structure and fertility. Ensuring that the soil has good drainage is crucial to prevent waterlogging and root diseases.
Light Requirements
Marigold thrives best in areas with full sun. It needs at least 6 hours of direct sunlight per day to flower abundantly. In very hot climates, it may benefit from some afternoon shade.
Irrigation
Calendula requires regular watering, especially during dry periods. However, it is important not to overwater to avoid root rot. Calendula prefers long but spaced waterings, allowing the soil to dry out slightly between waterings.
Irrigation Methods
Drip irrigation, or better yet, exhaled hose irrigation, is the best option for marigold, as it provides water directly to the roots and reduces the risk of leaf diseases such as fungus.
Seedling Care
Pest Protection
Marigold is fairly resistant to pests and diseases, but can be susceptible to aphids and caterpillars, although they will generally prefer other plants nearby.
Pruning and Maintenance
To obtain as many flowers as possible, it is good to prune faded flowers as they consume energy from the plant. But we must remember that in the case that we want to obtain the seeds, we must leave the flower on the plant until it is collected to ensure that the seed has fully matured.
How to Reproduce Calendula
Seed Reproduction
Calendula generally reproduces through seeds, which it produces in abundance.
To do this we let dry a flower still on the plant, in which will appear, if it has been pollinated, some structures in the form of small horns, like those in the photo.
Among these will be the seeds, which we can plant in seedbed or direct sowing in the soil if the weather is still warm. If not, it will be better to keep them dry in a paper envelope for the following year.
Direct Sowing
We have to take into account that it has to be sown after frost, since it does not resist them. They should be planted at a depth of approximately 1 cm and with a spacing of 20 to 30 cm between each plant.
Indoor Germination
In colder climates, seed germination can be started indoors about 6 to 8 weeks before the last frost. Seeds can be sown in trays or small pots and transplanted into the garden once the seedlings have 3 or 4 leaves.
Uses of Calendula
Medicinal Uses
Calendula has been used for centuries in traditional medicine for its healing properties. Among the main medicinal benefits are:
Anti-inflammatory and Antiseptic Properties
Calendula is known for its anti-inflammatory and antiseptic properties, making it ideal for the treatment of wounds, cuts and burns. Calendula creams and ointments are used to reduce inflammation and prevent skin infections.

Culinary Uses
Although less well known, calendula also has culinary applications. Its petals can be used as a natural colorant in cooking, adding a touch of color and flavor to salads, soups and stews.
Associations
Marigold produces substances through its roots that bother nematodes, parasites that attack the roots of plants, and through its aerial part others that scare away whiteflies and some beetles.
