Leucadendron are a striking shrub related to Proteas. Great for water wise gardens where they can tolerate poor soils and some drought, growing where most other plants would not survive. They make fantastic cut flowers, lasting for weeks in a vase.
Planting Calendar
Planting in autumn through to spring when the soil is moist, will give the shrubs time to establish before summer.
Prepare
Position
Leucadendron do best in full sun ( the more the better) with space to grow and plenty of air movement. They must have a very free draining soil and do better without root disturbance or competition from other plants. They will grow in any type of soil as long as it drains freely.
Soil
When planted into the ground Leucadendron likes a free draining, sandy acidic 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 Potting mix.
Plant
When planting into the ground, gently tap the plant out of its pot. Avoid damaging the roots when planting. 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 with Hauraki Peat 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. 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. Add some fine sand for extra drainage and plant as per above. When planting into containers plant in Kings potting mix.
