Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the plant from the container.
Carefully remove the plant from the pot ensuring not to disturb any of the roots.
Position in hole and backfill with soil, gently firming down. Form a raised or doughnut shaped ring of soil around the outer edge of the plant's root zone. This helps keep water where it's needed. Always water in well after planting to settle the soil around the roots and keep the soil moist for several weeks while the new plant establishes.
Mulch around the base with organic mulch, keeping it away from the base of the plant.
Westringias dislike having constant wet feet. Take care not to over-water.
When pruning, ensure that you only cut back to the soft leafy growth and not to hard wood. Westringias don’t respond well to hard prunes and won’t rejuvenate if cut back to hard wood.
If using as a hedge, space the plants at least 50 cm apart. This will also depend on the overall size of the variety chosen. If it is a larger variety you will need to expand on the spacing to reduce competition. If it is a dwarf variety, then you can plant them closer together to create a denser hedge.
