Miscellaneous ●

Soil

Any sunny site with good drainage.

Position

Full sun to partial afternoon shade.

Frost tolerant

None. Marigold cannot tolerate cold temperatures.

Feeding

Mix a light application of a balanced organic fertiliser into the soil prior to planting.

Spacing

Single Plants: 20cm (7") each way (minimum)
Rows: 20cm (7") with 20cm (7") row gap (minimum)

Sow and Plant

Sow marigolds in late spring, or set them out as bedding plants. In climates with long, hot summers, make a second planting in summer for great autumn colour. Broadcast seed into cultivated soil so that the seeds are about 5 cm apart and 1 cm deep. Thin to 20 cm apart in all directions for dwarf varieties; allow 30 cm between very tall varieties.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

The 'Gem' marigolds (T. tenufolia) bear edible blossoms with a spicy, citrus flavor.

Harvesting

Marigolds make good short-stemmed cut flowers for small bouquets. Don't rush to pull up plants that stop blooming but look healthy, because they will probably come back into bloom.
