Plant my kapuka
You can grow your kapuka in pot, or outside in the region with mild winters!
Outside, plant in very drained soil, in full sun. Be careful, if your soil is calcareous, some cultivars might not accept it.
Make a 20/30 cm planting hole, wider than the root ball, and if your soil is heavy, plan for 20 cm of gravel at the bottom of the hole.
Empty two watering cans in the planting hollow that you have shaped for this purpose.
In pots, plant in a large pot pierced at the bottom (5 liters or more), with a cup, in a mixture of potting soil or very ripe compost, on a layer of gravel. Water after planting.
Prune my kapuka
At the beginning of the summer, cut asymetric stems. You can cut your kapuka back gently by pruning the longest branches.
Always prune after flowering - best enjoy its fragrant flowers and the buzz of the bees !
Water my kapuka
The kapuka prefers well-drained soils and fears excess moisture, which can be fatal.
If yours is in open soil, no need to water it except in case of severe drought.
In pots, water on average once a week, with non calcareus water.
Mulch my kapuka
Mulch in a thin layer to avoid competition, since your kapuka doesn't do well in overly cool soil. You may also use a mineral mulch — gravel will do the trick — that you won't have to renew.
Repot my kapuka
After a few years in the same pot, your kapuka will appreciate that you renew a portion of its land, or even that you provide a larger container.
Remove it from its pot by holding it at the base of the trunk. If it seems blocked, cut the roots that have passed through holes in the bottom of the pot. Provide a new mixture of heathsoil and sand.
Shelter my kapuka
Bring in your plant, to a cold and bright room in October.
Put outside my kapuka
Bring your westringia out as soon as the severe frosts are over.
