Macropiper, commonly known as Kawakawa, is endemic to the north and south islands and has gained popularity in gardens worldwide. Its shiny heart-shaped leaves, and dark brown zigzag branches give it a distinctive appearance, making it an attractive addition to ornamental gardens.
Planting Calendar
Macropiper is best planted in spring and autumn.
Harvest In
August - November
From August to November the plant produces tiny flowers off spikes. Fleshy fruiting spikes appear on the female plant between January and February, turning a yellow to orange colour on maturity and providing food for native birds. The root, fruit, seeds and especially the leaves of the Kawakawa plant were favourite medicinal remedies of the New Zealand Māori.
Prepare
Culturally, Kawakawa has been used by the Māori people of New Zealand for generations as a medicinal plant. Its leaves are traditionally used for various remedies and teas due to their reported health benefits. In gardens, Kawakawa is valued for its unique foliage making it an interesting addition to native, tropical, or coastal landscapes. Many restaurants now use Kawakawa in the kitchen, where it gives a peppery taste to many dishes.
Position
Kawakawa does best in dappled light, to full shade, but is sensitive to cold and frost.
Soil
When planted into the ground Macropiper prefers 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 Saturaid, which helps with moisture retention in the soil.
Plant
When planting into the ground, ensure the plants is well watered then, gently tap the plant out of its pot. Dig a hole twice the depth and width of the plant’s root ball. Mix Kings Compost into your existing soil at a 50/50 ratio, add Kings Sheep Pellets then mix together. Backfill 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 help to break down the clay. When planting into containers plant into Kings Container Mix, as this has water retention crystals in it, which will help in keeping the soil moist.
Care
Watering
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 just allowing it to run off the top of the surface of the soil, aiming to keep the soil moist during hot periods.
Feeding
For strong healthy roots and plants, apply monthly applications of Aquaticus Organic 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.
Protecting
Protect from cold winds and frost.
Mulching
Mulch around the base of the plants (making sure it is not in direct contact with the trunk or base of the plant) with Living Earth More than Mulch. Mulching helps to reduce weeds as well as aiding the soil to lock moisture in the ground. Replenish mulch each spring.
Spraying
Caterpillars like a good munch on Macropiper leaving holes in the leaves. Spray at first sign of attack with BioNeem.
Pruning
This plant is generally low-maintenance. It requires little to no pruning, although light pruning can be done to maintain its shape or remove any dead or crowded branches.
General Care
When using sprays, chemicals or fertilisers always read the label and follow the instructions. Apply sprays in the evening to avoid harming beneficial insects.
