THE STAR BEGONIA PLANT
Introduction
Star Begonia (Begonia Boweri CV. Tiger (b. Albo-Picto)), also known as: Begonia in white, originally from Brazil in South America, has been introduced in China. The Puntiaguda Begon is a shrub with thin stems and elliptical leaves lanceolate with silver white spots. The flowers are green-white.
Developing
Morphological characteristics
Small shrubs with many branches. The stem is relatively thin, 60 to 100 centimeters high, the new branch is green, the old branch is purple brown and the branch is falling into the apex. The leaves are elliptical and lanceolate, with a bright green surface, with numerous silver white spots. The flowers are green-white.
The common cultivated species of the same genus are: B. preside-carnot: the whole stem of the plant is smooth and the knots resemble those of bamboo. The leaves are alternate, oblong and biased, the surface is green and there are many small spots, and the back and the petioles are dark red.
Growth habit
The Begonia with Estrella Punta is a temperate area, likes scattered light and the humid atmosphere, and its cold resistance is not strong. The ground must be loose and well drained.
Cultivation and management: The culture floor is preferably mixed with leaf litter, peat floor, garden floor, etc. Plants must be placed in a hobow in half shade or in a brilliant place for maintenance. The leaves are tender and prone to ulceration, so you should pay attention to the shadow after summer and try to avoid direct sunlight to cause burns to the edge of the leaves.
Irrigation in the growth season must be diligent to keep the earth in a humid pot. When the ambient temperature is less than 15 ℃ in winter, irrigation must be strictly controlled, or spray in the place of watering. The proper growth temperature is 18 ~ 21 ℃, the temperature too high is easy to cause burned sheets. In high temperature season, pay attention to surrounding air moisture, sprinkle 2 to 3 times a day. During the growth period, a compound fertilizer rich in phosphorus and potassium can be applied once a month, or a thin liquid fertilizer once every two weeks.
The winter temperature should not be less than 8 ℃. If the handling is not good during the winter, such as low ambient temperature and low light, when the plant is in a semi-Latin state, watering or fertilizing too much, roots and easy to rot. In general, in winter, plants must be placed in the shed in the morning and at night in sunlight, stop fertilizer and water control, and the leaves can rins with water near ambient temperature every two weeks. In general, it must be properly cut to maintain a beautiful posture and good ventilation.
Cultivation technology
Race
It is commonly used to sow or cut propagation, but racks can also be used for reproduction.
- Sowing and spreading can be carried out at the beginning of spring. Mature seeds are sown in the propagation pots, and the humus floor is integrated, and the roots can be rooted by maintaining approximately 16 ℃ and a certain humidity. When seedlings appear from 2 to 3 true leaves, they can be transplanted to the pot.
- Cutting propagation is better from May to June. Young outbreaks at the top of the plant are selected as cuttings, about 10-15 cm long, and are inserted into the culture sand bed. The sand bed is sprayed every day and, usually, it is rooted 2 to 3 weeks after insertion.
- Grouped varieties can also spread by Ramets. Divide the root system of weed plants into several groups. To avoid damage to the root system, plant them in the pots separately.
Diseases and pests
If the root knot insects damage the root system, it will affect the absorption of the root system and make the plants become dwarf and lose their greenery. They can be embedded with nematocides such as kexandan around the root system for control. In addition, when the moisture of the air is too high and the ventilation is poor, it is easy for gray mold to occur, and ventilation and medications must be strengthened.
