My display has been looking great, but in the recent really hot and dry weather the display is starting to go over. Is there anything that I can do?

Most years the displays carry on with later taller flowers masking the shorter earlier ones. Sometimes it’s just a question of giving nature a little bit more time. Even if the later flowers are less showy they will still have a lot of sparkle. If really looking tatty you can give them the ‘Chelsea chop’ which is a very high cut to knock off the seeding flower heads and stimulate a 2nd flush of growth and flowers.
