July is where a lot of edible gardens quietly lose momentum and it’s exactly why so many plots run out of steam in autumn. We’re keeping it simple and practical with a July seed sowing guide that helps you stay productive well beyond summer, even if your beds look full and you’re half in holiday mode.
We talk through what’s genuinely worth sowing now for succession and speed: salad leaves like lettuce, spinach, rocket and spring onions, plus quick wins like radish and turnips. We also cover the “last chance” feel of July for crops such as beetroot and carrots, and how choosing the right timing and varieties sets you up for lifting and eating later in the year. If your germination has struggled in the heat, we share straightforward fixes, including avoiding trays baking in direct sun and keeping watering steady.
The big focus is on brassicas for overwinter harvests and early spring rewards, from autumn cabbage and savoy to calabrese, kale, cauliflower and purple sprouting broccoli. We also get into the unglamorous but crucial side of mid-summer growing: protecting seedlings from cabbage white butterfly with netting, keeping polytunnels ventilated, watering tomatoes properly, and staying vigilant for aphids, slugs returning after rain, and potato blight warnings. There’s also a useful run-through of herbs you can still sow now and a list of flower seeds that can keep your borders moving.
If you want your vegetable garden, polytunnel, or allotment to produce for as close to 12 months as possible, this is the moment to act. Subscribe, share the episode with a gardening mate, and leave a review with the one crop you’re committing to sow this July.
