Cotton Growing Guide

Cotton

Crop Rotation Group

Miscellaneous 

Soil

Rich soil enriched with plenty of compost.

Position

Full sun.

Frost tolerant

Cannot tolerate frost.

Feeding

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.

Companions

Basil, Garlic, Coriander, Mint, Sage, Dill, Onion, Onions and Sunflower.

Spacing

Single Plants: 15cm (5") each way (minimum)
Rows: 15cm (5") with 15cm (5") 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.

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.

Troubleshooting

Night-flying beetles often chew holes in cotton leaves, but this problem is mostly cosmetic.
