Osteospermum perennial flowers that can survive winter in regions with mild climates. The more they’re sheltered and protected from the cold, the higher the chance of keeping them year after year.
Planting osteospermum
This is preferably done in spring. You may also plant in fall if winters in your region are reliably mild.
Be careful because the plant is vulnerable to freezing below 23°F (-5°C) and it cannot survive temperatures that are lower than that.
That doesn’t mean it can’t be grown; it just means you’ll have to grow it like annuals, sowing new ones every year in spring.
- Space plants 12 to 16 inches (30 to 40 cm) apart.
- Choose a sun-bathed area that is also sheltered from wind since wind makes the air cooler.
Propagating osteospermum
Sowing from seeds is the simplest and fasted method to propagate your osteospermum.
Pruning and caring for osteospermum
Care is simple and you’ll only have to water in summer whenever dry spells and high temperatures extend for a lengthy amount of time.
Remove wilted flowers regularly, this is called deadheading. This step helps stimulate the plant to produce new flowers.
- Winter is a time when you must protect your plant if you expect temperatures lower than 23°F (-5°C).
Watering osteospermum
Water only during days of high temperatures, and then again only if you notice the plant suffering due to lack of water.
Osteospermum is a very interesting plant because its foliage is evergreen and it stays magnificent in winter.
But this plant has a hard time coping with frost spells colder than 23°F (-5°C), especially if if they last more than a couple days.
- In mild-wintered areas, you won’t have any problem keeping the plant both in a pot or in the ground outdoors.
- Anywhere else, you’ll have to bring them indoors in a spot that is sheltered from freezing. It’s also worth a try to cover it with a thick layer of leaf mulch to help it spend the winter out.
