In order for the hibiscus to bloom profusely next year, it must be properly overwintered. More about the ideal location as well as planting time can be found here.
The hibiscus (Hibiscus) is native to the subtropical regions of Asia. It is an absolute lover of warmth and only a few varieties can survive the winters in our latitudes. We explain how you can get even the not so hardy hibiscus varieties through the cold season so you can enjoy the flowers next year as well.
Planting hibiscus: planting time and procedure
Common hibiscus (Hibiscus syriacus) is the only species that can survive a moderate winter outdoors in the European climate. But when exactly should you plant it and what else should you consider? We explain this step by step in the following sections.
The right time for planting
As soon as conditions allow in the spring, you should plant your hibiscus in the garden. The earlier it enters the growth phase, the better equipped it will be for the coming winter.
Note: It makes sense to keep even the common hibiscus in the first year still in the pot. This allows the plant to be placed in the warm during particularly cold conditions, allowing it to slowly adapt to the harsh winter conditions.
Planting hibiscus: bed and container
Hibiscus prefers very nutrient–rich soil. So if you plant your hibiscus in a pot, be sure to use fresh compost. When planting in the bed, the planting hole should be about twice the volume of the root ball. Loosen the soil deeply and mix it with plenty of compost. The more nutritious the soil, the more confidently you can hope for a lush bloom. You can also use a high-quality, nutrient-rich organic soil such as our Plantura Organic Flower Compost to create optimal conditions for the hibiscus.
Transplanting hibiscus: timing and procedure
Common hibiscus, initially grown in a pot, can be placed outdoors after the first winter. Transplanting should be done as early as possible in the spring to give the beloved hibiscus a good start to growth. When planting hibiscus, proceed as if you were planting it directly into the bed. Loosen the soil deeply and enrich it with compost. In this case, all of the soil of the root ball from the pot can be used.
Overwintering hibiscus in a pot
The hibiscus is a heat-loving plant from the subtropics of Asia. No wonder it is not particularly comfortable in European winters. However, common hibiscus is frost hardy and can survive moderate winters. However, to get used to it, the first year it should still be kept in a pot, so you can put it in the warm when temperatures are very low. Rose hibiscus, on the other hand, can no longer survive outdoors at temperatures below 12 °C. For it, only planting in a pot is suitable. During the winter you should water your hibiscus only moderately and never fertilise.
Tip: Even though the common hibiscus is frost resistant, you can help it through the cold months. To do this, simply layer some bark mulch on top of the soil around the main shoot. You can also plant evergreen ground covers around the main shoot of the hibiscus for cold protection.
