Frequently Asked Questions
Clay soils are not ideal for any Protea, however some varieties will tolerate heavy soils quite well. Always try to break up heavy soils with gypsum and organic matter.
There are a number of possible causes. The most common ones are:
The plant is not receiving enough sun light.
The plant has been pruned too frequently or at the wrong time.
There has been a stress event (drying out, heavy frost etc).
There is a nutrient problem.
Our products are seasonal so not all varieties are available at all times. However please speak to your local nursery. They can enquire with us as to availability of varieties that are not in stock.
All varieties should be watered well during their first two summers. After that, those shown on the label as drought resistant can be watered much less e.g. monthly during dry periods. If Proteas are being grown in pots, water daily.
Please read the Growing Advice articles for more details on watering.
Waratahs prefer some protection from the wind and sun, and need watering during summer. Feed during early spring with slow release native fertiliser.
If your soil is clay you will need to add gypsum to break it up and improve drainage.
This is most probably leaf miner. Ask you nursery to recommend a systemic (absorbed into the plant) insecticide.
Large proteas can be cut back in stages. Prune back one third of the plant to the desired size. Let the plant recover for 6 months before pruning the second third. Waiting another 6 months before completing the final third. This staged process reduces the stress on the plant.
There are many causes of this, here are some possible solutions:
Feed the plant with slow release fertiliser for “natives” in spring.
Ensure the plant is watered during summer.
The plant should be exposed to sunlight all day.
Avoid clay soils / add gypsum to break up the soil and improve drainage.
No, there is not enough sun to produce flowers and Leucadendrons will not get any colour.
Plant in spring after you would expect the last moderate frost (September or October). Be sure to select varieties noted as frost tolerant.
No, Proteas do not have a dormant period and dislike root disturbance. If you still want to try, here are some pointers to improve your chances of success:
Move the plant during winter.
Prune the plant, reducing it by about one third.
Take as large a rootball as possible.
Water well into new position. Keep soil damp and use mulch.
