Popular species and varieties
Hibiscus rosa-sinensis is the most popular species. The fast-growing, originally well-established in China and today in all tropical countries as a garden plant spread shrub can grow to a height and a diameter of 180cm. He has dark green oval and serrated leaves. From early summer to early autumn appear in large numbers short-lived flowers of 13 - 15cm width. The species has scarlet, unfilled flowers, in the various cultivars and hybrids you can choose between forms with half-filled and filled flowers in pink, apricot, yellow, orange and white.
Hibiscus schizopetalus, a shrub up to 180cm high and just as broad, native to tropical East Africa, forms thin curved shoots that may need support. The leaves are shiny green, and hanging on long stems red or orange-red flowers have very attractive fringed and curved back petals. The flowers, from which stamens and stylus hang out, appear in late summer.
Marshmallow loves a bright location without direct sun and temperatures of 16 - 24 degrees Celsius. A base of wet pebbles and regular spraying provide the necessary humidity. During the growth phase, the soil must be kept constantly moist and be fertilized every two weeks.
In winter, place the H. rosa-sinensis in a location with temperatures of at least 10 degrees Celsius. H. schizopetalus needs more heat, not only in summer, where it can be planted in a warm and sheltered outdoor space, but also in winter. Minimum temperatures of 16 degrees Celsius meet his requirements. Only pour so much that the substance does not dry out. Spice the rosemary every year in early spring. A strong pruning ensures large flowers.
Propagation: In spring or summer you plant cuttings of side shoots.
Pests and diseases
Aphids can attack the young shoots, flower buds and flowers. On lances and leaves, lions leave their wooly white tracks. A too dry sub-grade and cool night-time temperatures cause the buds to fall off. A growth disturbance causes the leaves to turn yellow and then fall off prematurely. Insufficiently bright locations inhibit the formation of the flowers.
The planting and care of rosemary
It is important to pay attention to planting the rosemary in a protected location, because the plant is frost- and wind-sensitive. Because of this, the ideal planting time is in spring. If you have selected young hibiscus, it must be protected, especially in the first two to three years over the winter. If the plant is small and in a bucket, it can be brought into the house. However, if the rosemary is outdoors, it can be protected with a thick layer of foliage. Branches of softwoods, such as yew or spruce, are loosely laid out to protect against cold and frost. For a short time, older rose sibling can also stand minus 20 degrees, but younger plants freeze at very cold temperatures. The hibiscus loves sunny and warm, so it is important to be careful when planting, to choose a sunny and light-friendly place, because only then does it thrive and grow. Otherwise, this plant is very easy to care for and needs no care, or any special nutrients in the form of fertilizer.
How is the rosemary cut?
Slicing rosemary is easy. Here it depends on the growth of the plant and on the satisfaction of the owner. If the hibiscus has a beautiful shape, it must be freed exclusively from weak and dry branches. The thin shoots are now cut to individual buds and even unwanted shoots can now be removed.Over the years, however, a rosé is becoming denser and must now be cut more regularly. A so-called rejuvenation cut can help to develop a hibiscus, which has developed unilaterally, to a beautiful and even shape. Here, dead shoots and overgrown branches are generously removed.
