Sow perennial seeds
In addition to sowing biennial summer flowers, the end of July is also the best time to sow home-grown seeds of hardy perennials such as poppies, delphiniums, irises, or lupins outdoors. The plants will also self-seed immediately after natural seed ripening. The smaller the seeds, the closer they need to be planted below the soil surface; larger seeds can be planted deeper. Make sure to keep the bed evenly moist after sowing, as seeds can dry out quickly in the summer heat. Some varieties take a long time to germinate, so don't lose patience! Homegrown perennials are naturally a bit more labor-intensive, but they are usually more robust than store-bought perennials.
