Culture methods of coral flowers

The coral flower, also known as the Brazilian feather flower, is a perennial evergreen subshrub of the family Acanthaceae, with dense flowers forming short panicles, rose-purple or pink, shaped and colored like coral, bright and elegant, suitable for decorating rooms, native to tropical and subtropical America, and is now cultivated as an ornamental plant. The gardens of various provinces in southern China are cultivated. Let's take a look at the breeding methods of coral flowers.

Growth habits of coral flowers

Coral flowers are common potted ornamental flowers in gardens, which bloom in summer and autumn. Red inflorescences are particularly soft and beautiful in the sun, with long flowering period and shade tolerance. Potted plants are very suitable for indoor decoration and arrangement. Potted plants are suitable for decorating balconies, living rooms, bedrooms and studies, and are often used in gardens for roadside or flower bed cultivation. Aquaculture needs full-day or half-day sunshine, likes loose and fertile slightly acidic soil, and likes slightly dry or humid environment.

Propagation methods of coral flowers

Coral flowers are commonly propagated by cutting. Generally in spring or autumn, the new branches or stem segments that do not bear buds are cut for cuttings, which are 5 cm long and 8 cm long. The lower leaves are removed, leaving only the upper 2-3 leaves, which are inserted in the culture soil mixed with peat soil and coarse sand. Pour enough water, then cover the flowerpot with a plastic bag, put them in the semi-shade for 15-20 days, and transplant after the new leaves grow, with a higher survival rate.

Culture methods of coral flowers

1. Potted plants: Sandy rotten leaf soil can be used in coral pot cultivation, or general garden soil can be used to add appropriate amount of river sand, sawdust and cake fertilizer, which can be prepared after composting and fermentation. 2-3 seedlings can be planted in one pot at the same time, or one seedling can be planted alone, which can promote the germination of lower lateral buds and form a better plant shape.

2, lighting: coral flowers like light, in addition to summer light when the need for appropriate shade, to avoid direct sunlight, spring and autumn season to see more sunshine. Northern areas generally enter the house in the first and middle of October, and put it in a sunny place after entering the house, stop fertilizing, the basin soil should be dry, if too much watering at this time is easy to cause defoliation and rotting roots.

3. Temperature: the room temperature of coral flowers should be kept above 12 ℃ during overwintering, and the branches and leaves should be sprayed with water close to room temperature every 7 to 10 days, which can not only increase air humidity, but also keep plants clean for photosynthesis, which is very beneficial to their growth and flowering.

4. Watering: the growing season of coral flowers not only needs to keep the pot soil moist, but also needs to sprinkle water on the ground near the flowerpot to increase air humidity. Usually apply thin cake fertilizer and water every 10 to 14 days, and cut off the residual flowers in time after the flowers are withered.

5. Pruning: when the coral flower seedlings grow to a height of about 15 cm after potting, they are coring, promoting more branches and more flowering. The adult plant combined with basin change is pruned once a year in early spring to keep the plant height below 50 cm and make the plant shape plump.

6. Diseases and insect pests: coral flowers sometimes have leaf spot disease, which can be sprayed with 65% Dysen zinc wettable powder 600 times. Insect pests are harmful to diamondback moths, leafhoppers and aphids, which are sprayed with 2000 times of deworming essential oil.
