Harvesting :Cut flowers as soon as they fully open, preferably in late morning, and promptly dry them. Calendulas make marginal cut flowers because they partially close at night. For medicinal use harvest and dry entire calendula flowers. Infuse them in vegetable oil to make a medicinal oil with a long history of use for healing burned or abraded skin.
Calendula blossoms are edible and can be used to bring orange color to rice or potato dishes, or snip them onto soups or salads for extra flavor and nutrition. Use clean scissors to snip off petal tips, and compost the rest.

Time to harvest: days

Troubleshooting :Elderly plants suffer from powdery mildew and other fungal ailments. It’s best to send them to the compost pile and grow fresh replacement plants in a new place.

Notes :Marigolds are a wonder-drug of the companion plant world. French marigolds (T. patula) produce a pesticidal chemical from their roots, so strong it lasts years after they are gone. Mexican marigolds (T. erecta) do the same, but are so strong they will inhibit the growth of some more tender herbs. Stinking Roger (T. minuta) has also been found effective against certain perennial weeds. Same with lupin, planting nearby roses causes them to grow vigorously
