For the first time in ages it’s lovely to see the soil baked dry, plants wilting, and water butts empty, and late summer descends. Borders that are established, or were planted early in the year should be in full flower now, and lovely to look at. It’s worth taking photos and making notes of what has done well (so yo can repeat it) and what hasn’t (so you can sort it out). You can take seeds from plants that have finished, and then cut the flower heads down if you want everything neat and tidy, or leave them alone for the wildlife to use. many useful insects overwinter in dead flower heads, and birds eat the seeds over the winter.
