Pacific Beauty Calendula

Calendula prefers full sun and well-drained, sandy soil with a pH of 6.0-7.5. It does best in a sunny spot with plenty of air circulation and regular watering. It is tolerant of drought and can handle some shade, but it will produce fewer flowers.

Start indoors a few weeks before average last frost or sow directly outdoors after danger of frost has passed.  Sow seeds 1/4" deep in moist, but well-drained soil.  Germination will occur in 5-15 days.  Thin to one plant every 6-12".  Will tolerate dry soil once established.

Set seedlings outdoors after danger of frost has passed, spacing plants 6-12" apart. Keep well-watered until established.

Calendula is prone to powdery mildew, rust, and other fungal diseases. It can also be affected by aphids, spider mites, and other pests. Overwatering can cause root rot and other problems.

Calendula make excellent cut flowers. They have a long vase life, and their bright colors and cheerful daisy-like blooms make them a popular choice for bouquets and arrangements.

CONSIDERATIONS:

Calendula is prone to outcrossing so different varieties must be isolated if more than one is present. To do this, cage plants and remove a different cage each day or cut all of the flowers off one variety to allow the other to pollinate, then repeat with the other variety after it's seed crop has matured. To save seeds, harvest the seed heads when they are dry and brown. Cut the heads off the stem and place them in a paper bag. Shake the bag to release the seeds (rub them if needed), then spread them out to dry before storing.
