Hibiscus is a hardy shrub that has large blooms, available in different colours in single or double forms. The flowers last for a day or two individually. Mostly it flowers in Spring and in Summer, but can flower at other times of the year. Normally it prefers a rest in Winter.
Germination Temperature (°F)
Water 2-3 times a week in Summer and in Winter, water only when top of compost is dry. Plant must not stand in water.
Feed every 2-3 weeks in Spring and Summer with flowering plant fertilizer.
Re-pot with house-plant potting compost in Spring when necessary. Old plants in large pots should have some of the old compost scraped away and replaced with rich soil-based compost.
Sow seeds in seed and cutting compost in Spring, not all seeds show at once. Transplant each seedling as it becomes large enough to handle and don't discard the container until well over the time suggested.
Propagate by taking fairly soft stem cutting in Spring or sow seeds.
Hibiscus prefers warmth and good light. In early Spring a light trim can help to shape the plant. Pinch back shoots when they are 6 inches long to encourage bushiness. Keep compost moist in Summer but drier in winter.
Cut stems down by half in Spring with sharp scissors. Cut at an angle just above a leaf or side shoot. If sap runs, smear ends with petroleum jelly to seal the wound.
Give plenty of light to Hibiscus. Dead flowers should be removed to prevent them falling on the leaves and causing them to rot. Full sun will do no harm to Hibiscus if the soil is not allowed to dry out.
On a sunny windowsill or in a standing pot.
Spray daily with soft tepid water in Spring and Summer and weekly in Winter.
Well drained soil.
Most plant cells look like little boxes full of green disks. The disks are called chloroplasts. Other organelles inside a plant cell include a nucleus (where the DNA is kept), a large central vacuole (where water and other materials are stored) and a complex internal skeleton or cytoskeleton made of various proteins.
