Gardenia variety
Water scorpion: The leaves are only 1 cm wide and 5 cm long. The flowers of the double-flowered flowers are 5-6 cm in diameter. Because of the delicate texture of the plants, it is most suitable for making bonsai and garden plants as low fences.
Big leaf scorpion: The largest plant in the leaves is also the highest, because the leaves are thin and grow vigorously, most need sufficient water and nutrients. The double-flowered flower is about the size of an adult's palm and is the largest variety of gardenia.
Mountain sassafras: The wild species inherent in Taiwan's mountain forests, full of fragrance when blooming in spring and summer. Six-petal single-petal flower, flower-shaped like a windmill, easy to fruit after flowering, fruit can be used as a dye for food and cloth.
Yutangchun: Plant dwarf branches and leaves, double-flowered flowers like roses, suitable for pot planting, is the most common variety of Gardenia. The flowering period is mainly in the spring and summer, and the flowers are sporadically visible in other seasons.
Flowerpot and soil selection of Gardenia
The selection of Gardenia flower pots is common with pots, purple pots, glazed pots, porcelain pots, etc. Among them, the most suitable for gardenia cultivation is the tile basin. In the family of flowers, glazed pots, porcelain pots, preferably as a set of pots, can play a decorative role, not suitable for plastic pots.
Gardenia prefers acidic soil with loose soil, loose soil, smooth drainage and slightly sticky texture. It is easy to turn yellow in alkaline soil and is a typical acidic plant.
The soil in the northern part is mostly neutral or alkaline, which leads to the lack of iron in the soil for plant utilization, which is one of the main causes of yellowing of the leaves. Therefore, potted hazelnuts in the northern region should use fertile acidic culture soil. Generally, it can be prepared by mixing 4 parts of grass carbon, 4 parts of garden soil and 2 parts of sand. During the growth period, 0.2% ferrous sulfate or hydrazine water is poured every half month or so, which can prevent the soil from becoming alkali, and can timely supplement the soil with ferrite to prevent the leaves from turning yellow.
1 Soak the roots of Gardenia seedlings in water, change the water once a day, and then plant them in a pot after a week.
2 Spread a layer of brick tiles on the bottom of the pot to facilitate drainage and then add a layer of soil.
3 Put the gardenia seedlings into the pots, continue to fill the soil, then gently compact the soil and pour the water.
Watering method and precautions of Gardenia
1 Gardenia likes to be wet. It is necessary to keep the soil moist in the weektime, and pay attention to increase the relative humidity of the air. Watering is suitable for rainwater or fermented rice water.
2 After planting, you should pay attention to watering, so that the potting soil is kept moist.
3 In addition to watering in summer, it is necessary to spray water to the leaves every morning and evening to increase the relative humidity of the air and make the surface of the leaves bright.
After flowering in April, only water can be watered and the amount of watering can be controlled.
5 Watering should be less in winter, so that the soil is in a damp and dry state. The surface of the leaves of the plants can often be sprayed with clean water to make it smooth and clean.
6 The soil in the growing season is kept moist. In summer, especially when the air is dry, it is necessary to spray water to the foliage and surrounding environment several times to increase the air humidity. Watering less in winter, keeping the soil moist and dry, placed in a sunny area indoors, and receiving more sunlight. It can withstand low temperature of -10 °C, and the leaves are frozen and detached below -12 °C. The room temperature is maintained at 3~5 °C.
Watering method and precautions for gardenia culture
How to water the gardenia
The fertile acidic soil is a typical acid-loving plant. It is susceptible to yellowing disease in alkaline soil, and the culture soil of 6 parts of humus soil and 2 parts of garden soil and yellow sand in the potting soil. It has high soil fertility and acidity and is suitable for gardenia growth.
Gardenia is fertilized, and it is necessary to apply top dressing frequently during the growing season. Apply a lower concentration of fertilizer once a month, or apply 0.2% ferrous sulfate or hydrazine water every 10 to 15 days to avoid soil conversion to alkali. Sex, supply iron to the soil to avoid yellowing of the leaves of the plant. It is necessary to add 1 or 2 times of phosphorus and potassium fertilizer before flowering, which can promote the growth of flowers, and do not fertilize gardenia in winter.
Before the flowering period in May, the application of phosphorus and potassium fertilizers 1 to 2 times will help the flowers to be hypertrophy and vigorous. Gardenia in alkaline soil is susceptible to yellowing disease (green deficiency), 1000 times of ferrous sulfate can be applied, watering, yellow leaf phenomenon will gradually improve.
Gardenia has comprehensive requirements for nitrogen, phosphorus and potassium. In family flowering, for the sake of hygiene, human excrement is generally not applied, but bean cake, vegetable cake and northern sesame oil residue are used. These fertilizers have relatively high fertilizer efficiency, relatively complete fat content, and are easy to use, and are commonly used for family flower cultivation.
Gardening environment requirements for Gardenia
illumination
Hi light, avoid strong light, like warm and humid climate, resistant to half yin, have certain cold resistance, not tolerant to drought. Spring, summer and autumn can be placed in bright areas with sufficient scattered light and less direct light, but still need to pay attention to the strong light at noon in summer.
temperature
The scorpion is not cold-tolerant, and it is not advisable to leave the room early in the spring in the north. It usually leaves the room in early May to avoid the danger of night cream. Usually enter the room in early October, the person room is placed in the sun, the winter temperature should be kept at 10 ~ 12 ° C, the minimum should not be lower than 5 ° C.
How to trim the gardenia?
1 Gardenia has a strong ability to sprout new shoots. In order to prevent overlapping and loose branches and leaves, it is necessary to trim and shape it at an appropriate time.
2 Gardenia is bred in April and forms flower buds. Therefore, in addition to cutting off a few complicated branches and leaves during the period of April to May, it is usually necessary to protect the flower buds.
In 36 months, the plants are flowering, and the unfinished flowers are cut off to promote the extraction of new shoots. When the new shoots grow 2 to 3 knots, the first topping treatment should be taken, and some axillary buds should be properly erased.
After the flower is withered in April, the second heart-treating treatment should be taken. The plant is trimmed and the top tip is removed to make it sprout new shoots and cultivate the crown, which makes the plant shape beautiful and the flowers are numerous.
Flowering period and management matters of Gardenia
Gardenia flowers are solitary on the branches or leaf axils, larger, white, and aromatic. Calyx green, cylindric, base gradually narrow, apex lobes often 6, corolla open after a tall disc, 6 petals. Stamens 6, without filaments, anthers linear, 2-loculed. Ovary inferior, 1 room, numerous ovules, slender style, extending out of corolla tube, stigma thick, rod-like. Gardenia flowering period is 5 to 6 months.
Mattresses need to pay attention to winter and cold protection
In cold places in winter, the potted hazelnuts should be moved into the room in the first ten days of October, placed in the sunny place, the room temperature can not be low; at 0 ° C, preferably kept at 10 ~ 15 ° C, can not be too high, such as more than 15 ° C, That is, ventilation should be cooled down, otherwise it is unfavorable for dormancy, which is unfavorable for the second year of growth and flowering To control watering, you must master the principle of dry and thorough pouring, usually one time for five to seven days. Always loosen the surface of the soil to make the soil breathable. At the same time, always wash the branches and leaves with warm water, so that the dust does not stain the leaves.
Summer of gardenia culture method
Because the climate of gardenia is hot and humid, the amount of clouds is high, and the light is not very strong. Therefore, the garden potted gardenia flowers only need half light during growth and development. Generally, there is plenty of sunshine in summer, and the gardenia flowers are placed on the outdoor balcony or in the courtyard. The above must be covered with light curtains or bamboo curtains to form a diffuse light. Under the illumination of the diffuse light, the color of Gardenia is relatively white and pure, the flowering time is kept long, and the fragrance is strong and lasting. If the gardenia is exposed to direct sunlight, the white flower will turn yellow for a long time, the flowers will be thankful, the smile will be fast, and the fragrance will not last. Therefore, according to the characteristics of Gardenia, it is necessary to shave in the summer to facilitate growth and development. However, in order to make the gardenia full of flowers, when the flower buds begin to bloom, move it indoors and place it in a bright, well-ventilated place.
During the flowering period, Gardenia can be extended into the room, which can prolong the flowering period. Because of the low temperature in the spring and summer, the indoor temperature is lower than the outside world, and the evaporation is also small, but pay attention to the amount of watering. At the same time, after the flower is defeated, it should be moved immediately. Go outside and get in touch with the sun. In order to reduce the adverse effects of carbon dioxide emitted by plants at night, the flowers are placed as little as possible indoors at night or moved in during the day. Move out at night. If the living room is spacious and the number of potted flowers is small, the damage is not great.
Gardenia breeding method and some precautions
Seeding, cutting, layering, and rooting are usually carried out, usually with cuttings or strips. During the rainy season, the healthy and tender branches of the year are used. The cuttings are about 15 cm long and can be inserted into the pots by the mud method. The depth of insertion is about 1/2 of the length of the ear, leaving the upper 2 pairs of leaves and buds. After pouring, always water, keep the soil moist, but avoid fertilizing water in the seedling stage. After the treaty is inserted, it can take root. In the spring of the following year (before and after the Qingming period), the transplanting of the upper pots was carried out in April, and the strong branches on the 3-year-old mother tree were used for the beading. After the initial pressure, the water is often poured to keep the soil tight. After that, the water can be watered less. After 20 to 30 days, the roots can be rooted. In June, the mother plants can be cut off, and the spring plants can be planted in the next spring.
