This is the big wildflower spesh! Diarmuid and Paul always get a huge reaction when they post photos of wildflower meadows on Instagram and there's a big move towards this type of gardening. They'll tell you how to choose the right seed mix, where to sow it, how you should go about doing it and at what time of year. Do you think summer begins in May or June? Well it turns out, it doesn't matter because you shouldn't be gardening according to the calendar.
