• Ventilation matters: Open doors or ends to prevent overheating and improve airflow.
• Support your plants: Use stakes or string systems to keep vines tidy and healthy.
• Consistent feeding: Balanced fertilisers once fruit sets support strong yields.
• Water carefully: Water at soil level to avoid wetting foliage and reduce disease risk.
• Pollination help: Tap trusses gently or use a soft brush to aid pollination where insects are scarce.

Polytunnels extend seasons and improve tomato performance, giving UK growers a head start and a longer harvest window, even in unpredictable weather.
