Growing cut flowers from seed is fun and easy, and with some careful planning, it’s possible to enjoy beautiful blooms in the house in every season.
A selection of hardy annuals and half-hardy annuals will give you a wide range of gorgeous blooms. Once they have germinated, here’s how to look after your plants so that you can keep cutting flowers for weeks on end.
More on growing beautiful cut flowers:
Thinning out seedlings
Thin out seedlings to give the plants plenty of space, right from the start.
Pinch out tips
Pinching out the tips of sweet pea seedlings
Pinch out the tips of annuals (with the exception of stocks) to concentrate energy on flower spikes.
Removing a side-shoot from a small geranium
Remove the side-shoots of plants such as pelargoniums and stocks, to concentrate energy on flower spikes.
Weed regularly by hand in between rows to reduce competition for food, water and light.
Tying twine between canes to provide support for a clematis
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.
Watering the soil of a pot full of flowers
Don’t let plants dry out. Water roots regularly, particularly during dry summers. Find out how to water your plants in summer.
Measuring out liquid plant feed
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.
