Sow winter radishes like Black Spanish, China Rose, and Mooli in December under a cold frame. Seeds go 1cm deep in rows 15-20cm apart. A cold frame raises soil temperature by 3-5 degrees, triggering germination when open ground is too cold. Expect to harvest in 8-10 weeks.

Before sowing your first seed, optimise your greenhouse environment. Position seed trays on the south-facing side where they'll receive maximum natural light. Install shelving to maximise vertical space?a standard 8x6 greenhouse can house 12+ seed trays when properly configured.
Insulate against temperature fluctuations by using bubble wrap on greenhouse walls during February?April sowings. This simple step maintains 3?5?C warmer night-time temperatures, crucial for heat-loving seedlings like tomatoes and peppers.

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.
