Crop netting
Nets protect citrus from hail, sunburn and wind scarring, the blemishes that cost you export packouts. Research in South Africa shows they can lift yield too.

What a net does
Questions
Not if the net is right. In CRI trials, white and clear nets did well, while red and yellow nets increased leaf growth and reduced yield. That's why we recommend a white net of around 18–20% for most citrus.
In the Citrusdal study, fruit size was the same in the first season and larger under the net in the second. Results vary by season and cultivar.
Researchers say more work is needed here. The clear wins are fewer blemishes, less sunburn and better packouts.
