Cotton Growing Guide

Gossypium hirsutum

Crop Rotation Group

Miscellaneous ●

Soil

Soil rich in organic matter.

Position

Full sun.

Frost tolerant

Cannot tolerate frost.

Feeding

Mulch the soil with compost before planting cotton. In midsummer when flowering begins, mulch again, or drench with a liquid plant food.

Spacing

Single Plants: 60cm (1' 11") each way (minimum)
Rows: 45cm (1' 5") with 1.00m (3' 3") row gap (minimum)

Sow and Plant

Sow directly when the soil is warm. In cooler climates start seed indoors and transplant out after the last frost, being careful not to disturb the roots. Water very well before planting.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

Cotton thrives on heat, but does not respond well to overwatering. In cool climates, grow individual cotton plants in large, dark-coloured containers to increase root warmth.

Harvesting

Harvest after bolls split open, during a period of dry weather. Cut cotton on long stems and dry in bunches, like herbs.
