June is where gardeners quietly win the year, or accidentally drift into gaps, gluts, and empty beds. With April and May running unusually cold, I’m using this June seed sowing guide to reset the clock and show what still makes sense to sow now, especially once soil temperatures rise and growth finally kicks on.

We talk through the real-world effects of sudden heat, particularly under cover. If your polytunnel is spiking into the 30s and 40s, some seeds simply will not play ball. Lettuce is the big one: once temperatures push past about 20°C, germination can stall, so tray placement matters as much as watering. I also share why seedlings are most at risk right now and how capillary matting can keep modules evenly moist for 24 to 48 hours, helping you avoid that heartbreaking “burnt to a crisp” moment.

Then we get into the sowing list, grouped in a way that makes planning easier: repeat salad sowings like spring onion, spinach, radish and lettuce, plus the smart-harvesting approach that stretches heads for longer. We shift into autumn and winter thinking with brassicas such as Brussels sprouts, cabbages, sprouting broccoli, calabrese, cauliflower and leeks, followed by roots like parsnips, beetroot, swede and carrots. Herbs and warm-season crops get a look in too, from basil and parsley to cucumbers, courgettes, French beans, squash, sweetcorn and peas. I finish with what you can still sow for flowers, why seed compost quality can stall growth, and how perennials and biennials started now repay you next spring.

If this helps, subscribe, share it with a gardening mate, and leave a review so more growers can find the podcast. What are you sowing first this June?
