Mint in June: monthly care

Mint benefits from regular pruning to encourage bushy, leafy growth and prevent it becoming leggy or flowering prematurely. The main pruning windows are June and September. In June, once plants are growing strongly, cut back stems by about half to promote a flush of fresh, tender leaves and delay flowering. This mid-season trim is especially worthwhile if you want a continuous harvest of young foliage for the kitchen. In September, after the main harvest period, cut all stems down to within 5 cm of ground level. This autumn cut-back tidies the plant, removes any tatty or diseased foliage, and encourages vigorous regrowth the following spring. Use clean, sharp secateurs or garden shears for the job. Throughout the growing season, pinch out flower buds as soon as they appear if you want to maximise leaf production. Flowering diverts the plant's energy away from foliage, and leaves can become slightly bitter once blooms develop. If you don't mind a reduction in leaf quality and want to enjoy the purple or pink summer flowers—which are excellent for pollinators—let a few stems bloom, but cut them back once flowering finishes. Mint requires no complex pruning techniques. It regrows reliably from the base, even after hard cutting. If clumps become congested or start to die out in the centre after a few years, lift and divide them in spring, replanting only the vigorous outer sections and discarding the woody core.

Mint has high water needs and performs best when the soil is kept consistently moist. Water regularly throughout the growing season, especially during dry spells in late spring and summer. In hot weather, check containers daily, as mint in pots can dry out quickly and will rapidly wilt if neglected. Reduce watering frequency in autumn and winter when growth slows, but don't let the soil dry out completely. Feed once in April with a balanced general-purpose fertiliser or a top-dressing of well-rotted compost or pelleted chicken manure. Mint is not a heavy feeder, and excessive nitrogen can produce lush but flavourless foliage, so a single spring application is sufficient. Container-grown plants may benefit from a second, lighter feed in mid-summer if growth appears weak. Mint is fully hardy across zones 3a to 9b and requires no winter protection outdoors. Top growth dies back in late autumn; simply cut it down and allow the roots to overwinter in the soil. Potted mint can stay outside year-round, though in very cold winters you may want to move containers against a sheltered wall to prevent the compost freezing solid. Common pests include mint beetle, whose larvae skeletonise leaves in summer, and aphids, which cluster on shoot tips. Pick off beetles by hand or tolerate minor damage; serious infestations are rare. Rust fungus causes orange pustules on leaves—remove and bin affected foliage promptly and thin congested clumps to improve air circulation. Mint is otherwise trouble-free and requires minimal intervention once established.
