Why You Need This Checklist

Does your garden feel like it should be winding down in September — but you sense there's actually a lot more you could be doing? You're right, and Charles Dowding proves it.

Most gardeners make the mistake of treating September as the end of the growing season. They stop sowing, slow down on planting, and let beds sit empty while winter creeps in. The result? Months of lost harvests, bare soil, and a garden that's barely producing by the time spring arrives. If you've ever looked at your plot in October and thought 'I wish I'd done more in September,' this checklist was made for you.

Imagine walking through your garden in November with beds full of lamb's lettuce, rocket, spinach, Chinese cabbage, mustard greens, and spring onions — all sown or transplanted from mid-September onward. Imagine knowing exactly which crops to pull, which beds to clear and replant immediately, how to layer sowings so something is always coming in, and how to protect what you've grown from rabbits, flea beetle, and allium leaf miner. That's what Charles Dowding's September system looks like in practice — and it's entirely achievable even in a busy season.

Charles Dowding is one of the UK's most respected no-dig growers, with decades of hands-on experience and a market garden that supplies real harvests year-round. In this September tour of his own growing space, he walks you through every bed — what he's harvesting right now (including over 30 kilos of salad leaf in a single morning), what he's just sown, what he's transplanting, and what mistakes he's navigating around flea beetle damage, drought, and timing pressures. He doesn't just share what to do — he shows you exactly when he sowed it, when he transplanted it, and what he expects by winter.

This PDF checklist distills every actionable step from that video into a clear, sequential guide you can print out and take into your garden today. Every variety name, sowing date, spacing tip, compost ratio, and protective measure Charles mentions is captured here — nothing left out, nothing vague. Whether you grow for your family or a small market, this checklist gives you the confidence to treat September not as an ending, but as a second spring.

Stop guessing what your September garden should look like. Use this checklist and follow the system that works.

What's Inside — Preview

Every checklist item comes with actionable notes to guide you — things like "Don't forget to do this before you start," "Avoid this common mistake," or "Set a reminder for 30 days out." Nothing vague, just clear next steps.

DO Clear out finished summer crops — watermelons, melons, and marigolds — from polytunnel or greenhouse beds immediately after harvest
DO Sow chard and kale as the first winter transplants into freshly cleared polytunnel beds
DO Prick out lettuce seedlings that were sown just 4 days ago into module trays
DO Prepare a 50/50 potting mix of homemade compost and bought worm compost (growworm type) for module sowing and pricking out
CHECK Assess flea beetle damage on brassicas honestly — identify which varieties are likely to recover and which are not going to make a worthwhile crop
