By July, spring's rush of sowing and planting can feel like a distant memory. Many gardeners quietly downshift into harvest-and-maintain mode, weeding, watering, and picking, and forget that beds emptied by finished broad beans, garlic, or early potatoes are prime real estate for a second round of crops.
Sow the right things now and you'll be harvesting fresh vegetables well into autumn and winter, instead of watching your plot go quiet the moment the summer glut passes.
Why Bother with a Second Sowing?
An empty bed in July isn't a rest, it's wasted growing time. With around three months of decent growing weather still ahead in most of the UK, there's enough season left for a whole range of quicker crops to mature before the cold really sets in, and for a few hardy ones to establish now and overwinter for an early spring harvest.
It also solves the 'August glut, September gap' problem: if everything you sowed in spring finishes around the same time, a second sowing in July keeps something coming through when the first wave is done.
What to Sow in July
Dwarf French beans: A last sowing in early July gives a crop before the first frosts. Choose a fast-maturing variety such as 'Sonesta'.
Peas: Quick varieties like 'Kelvedon Wonder' sown now will crop in autumn, when fresh peas feel like even more of a treat.
Beetroot: Sow through July for tender autumn roots, or let a later batch size up for winter storage.
Carrots: A July sowing of a maincrop variety such as 'Autumn King' gives roots that store well into winter.
Turnips: Fast and forgiving; 'Purple Top Milan' is ready in as little as 6-8 weeks.
Kohlrabi: An underused, quick-maturing crop that's happy sown right through summer.
Florence fennel: July sowings are far less prone to bolting than spring-sown fennel, giving you a much better chance of decent bulbs.
Chicory and endive: Sow now for bitter, crunchy leaves through autumn; varieties like 'Sugarloaf' form dense, self-blanching hearts.
Pak choi and oriental leaves: As days start to shorten later in the month, these are far less likely to bolt than they were in early summer.
Spring cabbage: Sow towards the end of July for small plants that will overwinter and crop next spring, right when little else is ready.
Getting Late-Summer Sowings to Germinate
July's challenge isn't the cold, it's the opposite. Hot, dry soil can stop seeds germinating altogether or dry them out before they get going.
Water the drill thoroughly before sowing, not just after, and sow slightly deeper than you would in spring to reach cooler, moister soil. A light covering of horticultural fleece or shade netting over freshly sown rows keeps the surface from baking and drying out between waterings, and check daily in hot spells rather than waiting for a routine watering day.
Protecting Your Second Sowings
July's pest pressure is often worse than spring's, simply because populations have built up all season. Cabbage white butterflies are in full flight and will find turnips, kohlrabi, and any other brassica-family crop within days, so net susceptible crops as soon as they're sown or planted.
Carrot fly remains a risk for a July carrot sowing; a fine mesh barrier or interplanting with alliums helps. Slugs are still a threat to anything germinating after rain, so keep up whatever control methods have worked for you so far this season.
Keep the Garden Working for You
Every bed that finishes in summer is an opportunity, not a full stop. A second sowing in July costs little more than some seed and a bit of watering discipline, and it's the difference between a garden that goes quiet by September and one that keeps producing through autumn and into the hungry gap beyond.
Pick two or three crops from the list above, clear a bed as soon as something finishes, and get sowing. Future you, harvesting fresh vegetables in October, will be glad you did.
