Leptospermum, commonly known as manuka is popular for its colourful flowers throughout winter and spring. This hardy plant has been bred for its ornamental value in home gardens with flowers in pink, white or red, against contrasting bronze foliage. Great for coastal or windy sites, native borders and can also be grown in containers. Great for attracting bees to the garden and is one of the main sources of nectar for Manuka honey.

Planting Calendar


The best time to plant Manuka is and spring/ summer and autumn.



Mānuka is tolerant of almost all growing conditions including the harshest wetlands, geothermal areas, dry exposed ridges and coastlines. They can be grown in full sun to partial shade


When planted into the ground Manuka does best in a free draining soil that is rich in organic matter. To improve the organic content in your soil, break up the soil and add Kings Compost and Kings Sheep Pellets then mix together well. When growing in containers, plant into Kings Container mix. This mix contains added water storage crystals and Saturaid, two products that help maintain moisture in the soil.


When planting into the ground, gently tap the plant out of its pot. Dig a hole twice the depth and width of the plants root ball. Mix Kings Compost into your existing soil at a 50/50 ratio, add Sheep Pellets and Kings 24 plus fertiliser, then mix together well. Back fill the hole with this soil, so that when planted the top of the plant’s roots sit level with the surrounding ground. Firm the soil down gently and water in well with Aquaticus Organic Garden Booster. In heavier clay soils, where drainage is likely to be an issue, plant onto a raised mound and sprinkle Gypsum Clay Breaker into the bottom of the hole, this helps slowly condition the soil and will help to break down the clay. When planting into containers plant in Kings Containers mix, as this has water retention crystals in it, which will help in keeping the soil moist. Firm the soil down gently and water in well with Aquaticus Organic Garden Booster.



Watering is essential especially in the first year of planting to allow the roots to get well established. Water slowly allowing the water to sink down into the roots, rather than allowing it to run off the top of the soils surface. Add Saturaid into the soil at planting as this will help channel the water deep down into the root zone. If planted in pots never allow the pot to sit in water.


When planted in the ground liquid feed every month with Aquaticus Garden Booster, from Spring through to the end of Autumn, this encourages root growth and increases the microbial activity in the soil. Monthly applications of Kings Sheep Pellets will help with soil conditioning and plant health. If planted into a containers feed with Kings Liquid Fast Food along with monthly applications of Aquaticus Organic Garden Booster this encourages strong roots and a healthy immune system.


Mulch around the base of the plants (make sure that the mulch does not come into direct contact with the stem of the plant) with Living Earth More than Mulch. Mulching helps to reduce weeds as well as aiding the soil to retain moisture.


Manuka are prone to Scale insect causing sooty mold to grow. Spray with Aquaticus Bugtrol as per instructions for control.


Generally Manuka do not need pruning. Prune only to remove dead wood and to shape.
