A patio garden in a small UK space produces colour, food, and wildlife habitat year-round. Pots of 45cm diameter or larger suit most flowering shrubs and perennials. Herbs grow in containers as small as 20cm. A 3m x 3m patio holds 15-20 containers for ornamentals, herbs, salad crops, and a trained fruit tree. Vertical growing on walls and fences triples planting space without using floor area.
Key takeaways
- 45cm pots suit most shrubs and perennials — 30cm for annuals, 20cm for herbs
- Vertical growing on walls and fences triples your planting space
- A single 50-litre grow bag produces 3-4kg of tomatoes or 2kg of salad leaves per season
- Terracotta looks best but dries out fastest — use plastic inner pots for less watering
- Group pots in odd numbers (3s and 5s) at varying heights for the most natural look
- Balconies typically support 150-250 kg per square metre — check before loading with pots
