Expert tips
The key tip
Manuka grows quickly in acidic, well-drained soil; in chalky soil, it struggles and gradually yellows. Progressive acidification or soil amended with peat at planting time prevents problems.
The common mistake
Don't water manuka too regularly: stagnant water is the real risk for manuka, far more than cold; temporary drought suits it better than constant moisture.
The pro's trick
In chalky climates, plant it on a raised mound with a generous addition of well-mixed blonde peat.
Care
Sunlight
Manuka thrives in full sun, requiring at least 6 hours of direct sunlight daily. A south or west-facing exposure is ideal to encourage blooming. In shade, the plant becomes less compact and flowers less abundantly.
Watering
Water regularly during the first year to establish a good root system, then gradually space out watering. During dry periods, keep the soil slightly moist without waterlogging. Reduce watering in winter and avoid hard water if possible.
Soil
Manuka prefers well-draining, acidic to neutral soil. A light, poor to moderately fertile substrate works perfectly. Incorporate heather peat or coarse sand if your soil is too compact or chalky.
Pruning
Prune lightly after flowering (June-July) to maintain a compact and dense shape. Remove dead or diseased wood throughout the year. Avoid severe pruning which weakens the plant; prefer regular pinching on young growth instead.
Fertilizer
A balanced fertilizer application in spring is generally sufficient. Avoid high-nitrogen fertilizers that promote foliage at the expense of flowers. Reduce or stop fertilizing in autumn and winter.
Diseases and pests
Manuka is generally disease-resistant. In overly humid environments, watch for root rot and leaf fungi. Improve air circulation and follow proper watering schedules to prevent these issues.
Did you know?
Manuka is world-famous for its honey, considered one of the most precious honeys in the world. New Zealand bees forage on its flowers during a short period each year, producing a dense honey rich in unique antimicrobial properties. This humble plant from the Myrtaceae family has transformed the beekeeping economy of an entire country.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
