Frequently asked questions about irrigating pineapple
What and how much irrigation do new varieties need?
Irrigation is being used more frequently when growing new varieties. It is important for good plant establishment, especially where smaller slips or tissue-cultured plants are planted. It is also vital for maintaining constant plant growth and minimising natural flower initiation.
Additionally, during droughts, irrigation can contribute substantially to fruit growth in the final six weeks before harvest. It might be also useful for sucker growth.
Avoid overhead irrigation during flowering as it could contribute to fruitlet core rot developing. Watering at this stage does not usually improve fruit size. Unless it is exceptionally dry, avoid irrigation in the final 2-3 weeks before harvest to avoid depressing total soluble solids (TSS) levels.
