Thin out seedlings to give the plants plenty of space, right from the start.
Pinch out tips
Pinch out the tips of annuals (with the exception of stocks) to concentrate energy on flower spikes.
Remove the side-shoots of stocks to concentrate energy on flower spikes.
Weed regularly by hand in between rows to reduce competition for food, water and light.
Stake plants with twine or canes to prevent them flopping onto neighbours and to keep flowers off the ground. Find out how to use plant stakes and supports.
Don’t let plants dry out. Water roots regularly, particularly during dry summers. Find out how to water your plants in summer.
Start feeding with a high-potash liquid fertiliser every two weeks once the plants come into bud – tomato feed is ideal. Read more about feeding plants.
Cut flowers regularly
Cut the flowers regularly, deadheading any that go over before you cut them, to encourage new blooms. Discover how to deadhead in summer.
When to pick flowers
Pick flowers in the morning if possible, when their stems are full of water and they are not under stress from the heat of the day. Otherwise, wait until the evening.
