Cotton Growing Guide

GossypiumĀ hirsutum


Crop Rotation Group



Rich soil enriched with plenty of compost.


Full sun.

Frost tolerant

Cannot tolerate frost.


Mix a balanced organic fertiliser into the soil before planting cotton. In midsummer when flowering begins, topdress with more fertiliser or drench with a liquid plant food.


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 personalised calendar of when to sow, plant and harvest for your area.


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.


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