Ideal Position
Sea-urchin Hakea prefers an open, full sun position and is perfect for a feature shrubbery. This plant and its neighbours should be well spaced so they don’t overlap once fully grown. For best results, avoid morning, overhead or afternoon shade.
Sea-urchin Hakea is ideally placed at the back of your garden bed.
When to Plant and Watering
Excellent screening plant. Plant young seedlings in Djeran (mid-Autumn) prior to the Makuru rains (Winter). Avoid planting in the hottest times of the year.
Seedlings should be watered twice a week over their first summer in the garden. It is important to ensure water penetrates down into the root-zone.
We recommend using a soil wetting agent as Perth soils are often ‘water repellent’, or do not absorb water effectively.
A layer of composted, coarse mulch can help in getting your garden started. It will help by reducing water loss and suppressing the growth of weeds.
Sea-urchin Hakea are waterwise, drought-hardy plants and do not require supplementary water once established.
Sea-urchin Hakea should be grouped with other waterwise, drought-hardy plants.
Feeding and Soil Care
Sea-urchin Hakea don’t need fertiliser because they are adapted to grow in our local soils, which are typically low in nutrients.
Plants will benefit from adding some vegetable-based compost (avoid those with manure) into the soil at planting.
As your garden develops, practice ‘cut and drop’ when you prune your plants. The leaf and branch material that falls to the ground slowly breaks down over time, releasing nutrients to help your garden to grow.
How to Prune
Sea-urchin Hakea generally don’t need pruning for shape, as their natural growth is usually attractive and/or interesting.
If part of the plant dies or grows in an undesired direction, prune from the base of the stem in question with a pair of secateurs or loppers.
You can also leave dead leaves and branches on the plant, as they provide valuable habitat and camouflage for insects.
