The following planting guidelines will assist you in achieving the best results for all
proteas, leucadendrons, leucospermums and waratahs. The family of proteaceae have
some very specific requirements, but if you get the planting right, they are one of the
lowest maintenance and most rewarding of garden shrubs.
Leucospermum's prefer a more friable soil type which can be achieved by mixing
washed sand, fine scoria etc with the soil at planting. They require excellent drainage. |

Generally this family of plants must have good drainage and will tolerate from sandy through to clay soils as long as the drainage is good.
They will not tolerate phosphates and nitrates commonly found in all garden manures. They like an acid soil with an extremely low nutrient value. So, do not fertilize . Do not plant near other plants that will require feeding as water will disperse food in the soil. Very old plants that are well established will find a small amount of urea beneficial but once every 2 years in the autumn is sufficient.
A windy position is preferable or at least good air movement around the plant.
Plants should be well staked at planting time to avoid root rock.
These plants love a full sun position and once established require little if any summer watering. Unless drought conditions arise no summer watering is necessary as the plants take all the moisture they require from the morning dew. New plantings in spring will need to be monitored to ensure sufficient moisture during the first summer.
The recommended planting time is autumn to early spring .
After the first flowering we advise pruning 1/3 to 1/2 of the bush annually but if you are looking for a large plant just “dead heading” is sufficient.
This family of plants is shallow rooting and does not enjoy being dug or forked around. It is best to mulch with bark [which is acidic] to avoid weeding or carefully weed spray around the plants.
Do not disturb the root system when planting. Just cut off the bag and place in the hole. Rocks or scoria may be added for improved drainage and stability but not lime rock . A few handfuls of peat may be added and mixed with soil in the hole to improve acidity where necessary.
