In northern and cool-summer climates, July sowing is about making use of long daylight while choosing crops that do not need prolonged heat to succeed.
Choose salads, radishes, leafy vegetables and fast annual flowers that can mature before the season shortens.
Starting seed in trays gives more control and protects seedlings from slugs, birds and heavy rain.
Kale, broccoli, pak choi, cabbage and other brassicas are strong July choices in cooler climates.
Beans, cucumbers, courgettes and sunflowers do best against warm walls, in greenhouses or on protected patios.
July is a useful time to sow biennials and perennials for stronger plants next spring.
