Light Requirements

Most edible plants need at least 6 hours of direct sunlight daily. South-facing windowsills and balconies get the most light in the UK. If your space gets less than 4 hours of direct sun, focus on leafy greens and herbs which tolerate partial shade. For year-round growing regardless of natural light, an LED grow light running 14-16 hours daily replaces sunlight entirely.

Choosing the Right Containers

Container choice affects everything from root health to watering frequency. Fabric grow bags offer the best drainage and air circulation for most vegetables. Self-watering planters are ideal for herbs and leafy greens that need consistent moisture. Whatever you choose, make sure it has adequate drainage holes — waterlogged roots are the fastest way to kill a container plant.

Common Problems and How to Fix Them

Yellow leaves usually mean overwatering or nutrient deficiency — check drainage first, then consider a balanced liquid feed. Leggy seedlings are reaching for light — move them closer to a window or add a grow light. Aphids cluster on new growth and can be blasted off with a strong spray of water. Blossom end rot on tomatoes comes from inconsistent watering — maintain even moisture and the problem stops.

Quick Tips for Success

  • Harvest herbs from the top down — cutting the stem tips promotes branching.
  • Pinch herbs regularly to encourage bushy growth and prevent flowering.
  • Succession sow salad greens every 2-3 weeks for a continuous supply.
  • Perlite mixed into potting soil improves both drainage and aeration.
  • Choose dwarf or compact varieties bred specifically for containers.
