Simon Akeroyd, a gardening specialist and author of over 30 gardening books, has introduced a sustainable method for reusing empty milk cartons as watering cans. By piercing the lid of the carton to create a nozzle, gardeners can achieve a gentle spray that effectively waters plants without washing away seeds or seedlings. This innovative idea, shared on TikTok, has resonated with users who appreciate the dual-purpose use of milk cartons. Akeroyd emphasizes the importance of watering based on environmental conditions, using techniques like the 'finger test' to determine moisture levels. He advises watering deeply but less frequently to encourage robust root growth and suggests early morning as the optimal time for watering. Additionally, he notes that potted plants may require more attention during warmer months, highlighting the need for regular checks to prevent drying out. This eco-friendly approach not only reduces waste but also promotes sustainable gardening practices.
