At this time of the year many of the plants are starting to look tired and flowering is limited. Deadheading is really important to keep the blooms going during the summer. It can be a labour intensive chore but it is very important. If you leave the dead heads on them the plant will go on to seed and produce no more flowers. Even if the flower head is just starting to turn you can remove it as the plant will produce more flowers. Once the plant is going to seed it will put all its energy into producing the seed and will quickly die off. Obviously the rain doesn't help with the flowers as it quickly turns then so it is important to get out regulary and remove all fading flowers. If you do half and hour a day deadheading then it's not so daunting as it would be doing it once a week.
My name is Jonathan and I enjoy working in my garden in my spare time. I am no professional, just an amateur. My second love is photography, shooting the flowers in my garden and of course sharing them with people who share my passions.
