What to Grow in Greenhouse August UK

Matt W · 9th Jul 2025

August in your UK greenhouse is about maximising opportunities. You're harvesting the rewards of summer growing while investing in winter abundance. The key is understanding that successful August growing requires active management—this isn't a month to set things up and hope for the best.

Focus on heat management first. Get your ventilation and shading sorted before you start sowing because failed sowings cost time you can't recover this late in the season. Once conditions are right, be bold with your sowings—your greenhouse gives you growing opportunities that outdoor gardeners simply don't have.
