Aphids are back: how to stop them taking over your lemon tree this spring

Key points

• Black citrus aphids are feeding on soft new growth of lemon and other citrus trees in spring and summer. The pests can be identified by curled leaves, sticky honeydew, and black sooty mould.
• Horticulturist Liam Kemp recommends treating infestations early with organic sprays or natural predators like ladybirds and lacewings.
• Prevention includes checking new plants, using balanced fertiliser, and strategic pruning.
