Give your spare space a good weeding before sowing anything, as weeds will compete for light, space and food. Once you’ve removed everything, dig over the soil and firm it back down before raking it smooth.
Scatter your wildflower meadow seeds by hand. Rake in lightly and water thoroughly. If you’re particularly worried about birds eating them all, put some netting over the soil.
Make sure the soil remains moist and warm while they’re germinating. The key thing is to make sure they don’t dry out. A single blisteringly hot weekend will stop them in their tracks. And watch out for weeds coming back too.
