Sow Inside: No need. Carum plants bought at a nursery can be transplanted following the last frost.

Requirements: Full sunlight. Good drainage. Soil pH 6.0 to 7.0.  Light but fertile soil. Give nursery transplanted Carum a feed when planting. Feed again when plants start to grow with vigour. Propagate: Allow to self seed.
Miscellaneous: Caraway is grown for its seed. Harvest seeds by cutting off the flower heads once the seeds turn brown in the middle of summer. Place the heads in a paper bag. Rub the bag gently to loosen the seeds. Carum seeds are susceptible to insects; therefore once seeds have been harvested they should be put into boiling water to remove any insect infestation. Next the seeds should be dried in the sun for a couple of days. They can now be stored in a Tupperware or other suitable container until they are required.

How to Grow Caraway - Carum

Seeds of carum should be sowed at a depth of 3 mm into a light soil with good drainage (pH 6 to 7) in either early autumn or early spring. It is best to sow from fresh seeds and they take about two weeks to germinate.

If you buy caraway from garden centers then they should be spaced out at a distance of 20 to 30 cm (8 to 12 inches).

Carum should ideally be grown in a sunny part of the garden. Once established the plants should not be moved.

They are fairly easy to look after, they do however require feeding at the time they are planted and when they are growing at their most vigorous.

Harvesting Carum Seeds for Use in Cooking

If you plan to use Carum seeds for culinary purposes then they should be harvested when the seeds become brown in the middle of summer.
