For lasting joy...
Pick flowers often to enjoy indoors – this will help promote new buds and extend the show. If you prefer to keep the garden outdoors, deadhead or remove dead flowers regularly.
Feed regularly with a liquid fertiliser high in potassium – this will provide plants with the nutrients they need to continue to bloom.
Look out for signs of pests or diseases and treat at first sight with a suitable product. Gardenias are prone to scale, while roses suffer from blackspot and aphid attacks.
