Growing English Ivy in a pot

Once established, English ivy is drought-tolerant and needs watering only during prolonged dry spells in summer—give it a thorough soak every two weeks rather than frequent light sprinklings. In the first year, water weekly if rainfall is scarce. Ivy growing in containers or against hot south-facing walls will need more regular attention. In autumn and winter, natural rainfall is almost always sufficient. Feed once a year in April with a balanced general-purpose fertiliser (such as blood, fish and bone or a granular NPK feed) scattered around the base at the rate recommended on the packet. Avoid high-nitrogen feeds later in the season, which promote soft growth vulnerable to frost. Ivy is evergreen and fully hardy across zones 4a–9b, so no special winter protection is needed. Refresh the mulch layer each spring to suppress weeds and conserve moisture. English ivy is generally robust but can occasionally suffer from scale insects, which appear as small brown lumps on stems and leaves, and aphids on new growth in spring. Treat heavy infestations with an insecticidal soap or horticultural oil. Leaf spot and powdery mildew can occur in crowded, poorly ventilated growth—improve air circulation by thinning congested stems. Root rot may develop in waterlogged soil, so ensure good drainage at planting. Keep an eye on ivy's spread. It can self-layer where stems touch the ground and may seed into borders from the autumn flowers (which appear on mature, non-climbing adult growth). Remove unwanted seedlings and rooted layers promptly. Check annually that it isn't lifting roof tiles, blocking gutters, or damaging mortar on older walls.
