1. Keep up with deadheading

Know how to deadhead petunias and you can keep them blooming. ‘Although we grow most plants for their decorative flowers, they actually flower to produce seed,’ explains gardening expert Steve Bradley.

‘Once the flower has been pollinated and the seed embryo fertilized, the plant feels it has done its job and flower production gradually stops. All the plant’s energy then goes into the developing seeds.

‘With petunias, deadheading can be carried out as soon as the tubular flowers start to collapse, but it is better to wait until the flowers start to shrivel and die. At this stage, the whole flower will break away from the plant, rather than tearing, and the easiest way to remove them is to pluck them off using finger and thumb.’

OK, this tip isn’t going to help you now if you’ve already planted petunias in a shady bed or border (although it will prove useful for the future). But if you’ve put these colorful flowers in shade when they’re in containers or hanging baskets then you can move them to boost flower production.

4. Water according to where they’re planted

For thriving petunias and a great display of blooms, keep up with the watering. If they’re in a bed or a border, then thorough watering once a week should be sufficient. Soak the soil to a good depth (we’re talking 6 inches); this helps them produce deep healthy roots.

Bear in mind that petunias in containers need to be watered more frequently and watering hanging baskets sufficiently is equally important – even as much as daily care can be required since they dry out more quickly. Water a container until you see it flowing out of the base.

5. Feed petunias

Petunias need fertilizer to put on their best show of flowers. ‘Petunias are hungry plants and need regular feeding with a high potash feed as soon as the first flowers open to help increase and prolong flowering,’ advises Steve Bradley. ‘Regular liquid feeds tend to have a more instant effect on the plants’ flowering performance.’
