Tips for Growing Tomatoes in Window Boxes (UK)

• Use deep, well-drained soil: Aim for at least 25–30 cm (10–12 in) depth to support roots.
• Feed frequently: Liquid feed every 1–2 weeks keeps crops productive.
• Water daily: Window boxes dry quickly — consistent moisture improves fruit set and flavour.
• Choose sunny, sheltered spots: Maximise light and warmth, especially in cooler UK summers.
• Light support for trailing types: Small ties or clips keep vines tidy and manageable.

Window-box tomato growing turns even narrow ledges into productive fruiting space — just pick compact, manageable varieties and give them sunshine and regular care.
