The Miracle-Gro 2 in 1 Nourish & Protect range is perfect for feeding your plants whilst simultaneously protecting them from pests and disease. The Miracle-Gro 2in1 Nourish & Protect Ready To Use Plant Food can be directly sprayed onto the leaves of roses, shrubs and other ornamental plants every 2 weeks from early spring to late summer to provide nutrition and protection from aphids, mealybugs, red spider mites, black spot, powdery mildew and rust. The Miracle-Gro 2in1 Nourish & Protect Flowers, Fruit & Veg Plant Food creates a physical barrier with natural lava rocks which prevents slugs and snails from eating the foliage and fruits and adds nutrition to the soil around the plant at the same time.
