Let’s dig in!
Why July Is a Great Month for Planting
July is one of the best times to sow seeds. With warm soil, long daylight hours, and high air temperatures, conditions are perfect for quick germination. These ideal growing conditions give you the chance to extend your harvest in the veg patch and boost your supply of perennials, biennials, and exotic plants in the ornamental garden. Just keep in mind—mid-summer often means dry soil, so be ready to water more than usual.
In the UK, there’s still a wide range of seeds you can sow in July. Biennials like foxgloves go in now to bloom next spring. It’s also a great time for fast growers such as radishes, carrots, French beans, and soybeans.
July is also the final call for planting out certain young plants. If you’ve got courgettes, squashes, or sweetcorn ready to go, get them in the ground early this month—they’ll need time to mature before autumn frosts arrive. And don’t forget your winter cabbages. Seeded back in April or May, they should be planted out now to ensure they’re full-sized and ready in time for Christmas dinner and beyond.
So what should you plant now? Let’s dig in.
