To promote bushier growth, pinch the vegetative buds when the plants are several inches tall. This will also encourage more blooms.

Calendula generally has few pest problems, but may have issues with aphids, powdery mildew, and cucumber mosaic virus. Regular deadheading is essential to encourage blooming and prevent self-sowing.

Calendula is a hardy plant that can thrive in poor conditions, but it grows best in well-draining, nutrient-rich soil.

To give your calendula the best chance to succeed, plant it in a spot that gets full sun, as it's a sun-loving plant. However, be aware that it may start to wilt in intense heat.

You can sow calendula seeds directly in the garden just before the last frost date, but for an earlier bloom, start seeds indoors about 6-8 weeks before the last frost. This will give you a head start on the growing season.

Calendula has no serious insect or disease problems, but it can be susceptible to powdery mildew, which can be remedied by good air circulation.

Slugs and snails may feed on the plants, especially when they're young, so keep the ground clear of debris to minimize damage.

Aphids and whiteflies can sometimes be a problem, but they can be easily controlled by spraying them with water or treating them with insecticidal soap.

To keep your calendula healthy, make sure it gets full sun and partial shade, but avoid planting it near shady trees as it needs sunlight to thrive.
