Culture methods and matters needing attention of Gardenia jasminoides

Too much watering: gardenia likes a moist environment, but it is not resistant to waterlogging. If too much watering can not be absorbed, it is easy to rett the roots, resulting in yellow leaves and fallen leaves. It is necessary to drain water as soon as possible, strengthen ventilation, loosen the soil and evaporate water frequently. Late watering to control the amount of water, moisturizing on the line, no stagnant water. The light is too strong: gardenia likes light, but is afraid of strong light.

Cultivation methods and precautions of Gardenia jasminoides (1) when selecting soil, you need to use acid soil with loose, good drainage and base fertilizer. Lighting likes scattered light in the morning and evening. Water in spring and autumn, you should water every 3-5 days, in summer, you should water every 2-3 days, and in winter, you should water every 5-7 days.

Acidic soil Gardenia likes acidic soil, so when maintaining, it should be noted that the pH value of its soil is preferably between 5 and 6. Generally use rotten leaf soil, peat soil and half of the garden soil to prepare, do not add coal, otherwise it is not conducive to growth. In a semi-shady environment, gardenia likes to grow in a semi-shady environment, so don't let it accept direct sunlight, but it can't be completely without sunlight, requiring half shade.

What is the reason for falling leaves and flowers of gardenia at home?

1. Gardenia yellow leaves drop bud reason the air is too dry gardenia is a potted flower in the south, like the environment with relatively high air humidity, if the gardenia is often raised indoors, the air humidity is insufficient, especially in the northern area, the indoor humidity is particularly dry, it is easy to appear withered phenomenon.

2. Insufficient ventilation: ventilation is very important for any plant growth. Poor ventilation will not only affect the poor growth of plants, but also easily lead to the occurrence of diseases and insect pests. Move the flowers to a ventilated place and recover by themselves.

3. Pictures of gardenia in potted plants the main reasons for the occurrence of withered branches and leaves in potted gardenia are as follows: rotten roots caused by long-term stagnant water in ① basin soil. ② basin soil has been dry and dehydrated for a long time. Improper fertilization of ③. The fertilizer applied was too thick or not fermented enough to burn the roots. The summer pot of ④ has been exposed to the sun for a long time. ⑤ basin soil is used improperly and is seriously alkaline. ⑥ potted gardenia was seriously damaged by freezing.

Get to know Gardenia

Gardenia flower cultivation needs to use weak acid soil with good air permeability and pH between 5-6, and half of garden soil mixed with rotten leaf soil and peat soil can be used as its culture soil. Sufficient sunlight is a necessary condition for the growth of gardenia. If there is no light for a long time, its branches will be very thin and difficult to bloom. Gardenia likes wet growth conditions and should keep the basin soil moist except in winter.

Gardenia, also known as Gardenia jasminoides, Gardenia jasminoides, is an evergreen shrub of Gentiana, Rubiaceae and Gardenia jasminoides. It likes warm, moist and sunny environment, is cold-resistant, semi-overcast and afraid of stagnant water, and requires loose, fertile and acidic sandy loam.

Gardenia jasminoides is a variety of gardenia. It belongs to the genus Gardenia of Rubiaceae. Evergreen shrubs. Single leaf opposite or 3-leaf whorled. Like humid, warm, well-lit and well-ventilated environment. Cuttings, striping, split plants or sowing can be used for propagation. Flowers can be used as spices for tea, and fruits can reduce inflammation and dispel fever. It is an excellent fragrant flower.

But they don't grow on trees. On the contrary, gardenias usually grow on the ground, or slightly higher. Some plants that are used to growing on trees, such as locust and persimmon, can lead to serious death of gardenia.

2. Gardenia is also known as Yellow Gardenia, Golden Gardenia, Silver Gardenia, Gardenia jasminoides, Lin Lan, Mulan, Yuetao, wooden branches, Jade Lotus. Gardenia life habits enjoy the sun, withstand shade, in the shade conditions can keep the leaf color dark green, but the flowering is slightly worse. Like warm and humid environment, heat-resistant and cold-resistant,-3 ℃ can survive the winter safely.

3. Gardenia (scientific name: Gardenia jasminoides), also known as Gardenia jasminoides, yellow gardenia. Belong to dicotyledonous class, Rubiaceae, gardenia evergreen shrubs, luxuriant branches and leaves, evergreen leaves, fragrant flowers, is an important garden ornamental plant. Single leaf opposite or tricuspidate, leaf blade Obovate, leathery, emerald green and glossy. Berries ovate, yellow or orange.

From March to July, it blossoms once a year, and the flowering period is longer. Note: soil: the choice of soil also has something to do with later flowering. Nutritious, good drainage, and must be acidic soil. If the soil is alkaline, it is easy to prevent the plant from blooming. Pruning: if not pruned, some messy branches and dense branches will consume too many nutrients, and the supply of nutrients for flowers will not be enough. Therefore, it has to be pruned before flowering.

How to raise gardenia

The light is too strong: gardenia likes light, but is afraid of strong light. If you are exposed to direct light for a long time, it is easy to sunburn and yellow leaves fall, you need to move to the semi-shaded ventilation place as soon as possible, cut off the yellow leaves, provide a warm environment, and promote recovery as soon as possible. The temperature is too low: the cold resistance of Gardenia jasminoides is poor, if the temperature can not be well controlled in winter, it may be frostbitten in the environment of about 5 ℃ for a long time, resulting in yellow leaves, or even leaves falling.

Lighting: gardenias need plenty of sunlight, but avoid strong direct sunlight. Temperature: Gardenia jasminoides is suitable to grow in warm environment, and the suitable growth temperature is 15 ℃-28 ℃. Watering: gardenia needs plenty of water, but too much water can lead to root rot. Fertilization: gardenia needs the right amount of nutrients to maintain its growth and flowering, so it needs to be fertilized every spring and summer.

The correct time to change the basin should be before the growth of green plants and when new buds sprout. Gardenia maintenance precautions the most common problem in the maintenance process of Gardenia jasminoides is chlorosis caused by iron deficiency, the main symptoms are young leaves and twigs, at the beginning, the twigs and leaves are light yellow or white, the leaves are very small, and the veins are still green. in severe cases, the veins in the leaves will also turn yellow, resulting in leaf death.

Bask in the sun. Gardenia likes light and can grow in semi-shade for a long time, but the flower branches are longer and the flowers are less. In addition to the strong light from July to August noon need shade and winter dormancy period, generally need to be maintained in the sun in order to blossom and flourish. Look at the big picture of Gardenia jasminoides. Fifth, good dormancy in winter. Gardenia can survive the winter in the open field in Qinling Mountains of China, but the root system of potted gardenia will be damaged after severe winter and recover slowly in spring.

Pot soil pot planting of gardenia should be carried out in late autumn, with soil balls on the pot. Gardenia likes acidic soil, and most of the soils in the north are neutral or alkaline, which is one of the main reasons for leaf yellowing. Therefore, the maintenance of gardenia should choose fertile acid culture soil. Generally, it can be mixed with 5 parts of rotten leaf soil, 3 parts of garden soil and 2 parts of sandy soil, and 1 kilogram of sulfur powder should be mixed in every kilogram of culture soil.
