How to raise potted gardenias? It only takes seven steps to do it easily.

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 has luxuriant branches and leaves, evergreen leaves and fragrant flowers. It is an important garden ornamental plant. Let's take a look at the cultivation methods of potted gardenia.

How to raise potted gardenias?

1. Select suitable basin soil

Choose the right basin soil. Gardenia jasminoides is an acid-loving flower with a suitable pH value of 5 to 6. If the soil acidity is not suitable, it will get twice the result with half the effort in the future management. Cultivation soil can choose rotten leaf soil, peat soil or retting sawdust plus half of the garden soil, avoid using old wall soil and cinder, with the market of gentleman orchid soil is more convenient and practical.

two。 adequate manuring

adequate manuring. Gardenia likes to be fat. 3% rotten cake fertilizer can be added to the culture soil as base fertilizer. During the growing season, the alum fertilizer made by cake fertilizer and ferrous sulfate retting is watered once a week, or 0.1% humic acid total nutrient organic liquid fertilizer can be used. Watering 0.1% potassium dihydrogen phosphate aqueous solution once or twice in the bud stage can make the flowers fat and fragrant. Fertilizer is stopped when the temperature is above 35 ℃ in hot summer and below 15 ℃ in autumn.

3. Scientific watering

Scientific watering. Gardenia likes moist soil and high air humidity. Keep the soil moist during the growth period from April to September. The surface of the basin soil is watered when it is dry, and a spray can be used to pour water on the leaf surface at night. If it is dry and wilted, it will be bad for growth. If the growth is too prosperous and the internodes are longer, they will not be watered in the evening and will be watered again when the sun comes out in the morning. In the area of alkaline water in the north, tap water should be kept for two days before use. Every three or five days, add 0.5 grams of citric acid and 1 gram of ferrous sulfate to water once per liter to make the leaves oily and green.

4. Bask in more sun

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.

5. Good dormancy in winter

Dormancy is good 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. In the indoor with heating, although it is not damaged by freezing, the light is insufficient and the growth is thin. Most of the young buds formed in autumn fall off and blossom late in the second year. The better way is to put the potted flowers in a cold room of about 5 ℃ to make them dormant, or wrap the flowerpots with foam and other thermal insulation materials to protect the roots, and put them in the leeward and sunny place to overwinter, which can recover quickly in spring and bloom early.

6. Proper pruning

Trim properly. Gardenia jasminoides seedlings in the trunk 20 cm high to hit the top, leaving 3 to 4 branches, branches 2 pairs of leaves and then hit the top, promote branches, and then allow its growth. Lobular gardenia does not need to be topped. Trim lightly after flowering every year, cut off the inner chamber branches, diseased and weak branches, and some only grow short branches. When the crown width of Gardenia jasminoides is too large after 4 to 5 years, it can be strongly pruned after flowering, generally leaving 2 pairs of leaves in the upper part of the branch. After budding, the inward growing buds and the lower buds of the trunk will be erased, and the plant shape will become more compact and beautiful. Remember that gardenia can not be cut short in spring, otherwise it will not blossom in that year.

7. Change basin soil at the right time

Change the basin soil at the right time. The seedlings are planted in small pots and gradually replaced into large pots. When the crown width is 2 to 3 times the caliber of the basin, it is time to change the basin. The growing season can be changed at any time. After pouring the basin, even the soil block is planted into the new basin, the caliber is about 5 centimeters larger than the original basin. Family potted plants when the pot reaches about 28 cm, generally no longer change the pot but only change the pot soil. It is better to change soil in March in spring. After pouring the basin, cut off part of the old roots, shake off half of the old soil, plant the new soil into the basin and pour water into the pot, put it in a warm semi-shady place, and keep it in the sun when new buds sprout.

How to raise gardenia with big leaves?

Northern conservation of Gardenia jasminoides is often due to climate, soil and other conditions are not suitable for its growth and development, resulting in the leaves of Gardenia jasminoides turned yellow and even the whole plant died. For this reason, the northern conservation of Gardenia jasminoides must master the following points.

Gardenia jasminoides has strict requirements on the soil and grows well in the acidic soil of pH5-6, while the soil in the north is generally neutral or alkaline. In this soil, iron hydroxide insoluble in water is formed due to the hydrolysis of iron salt, which can not be absorbed by plants, resulting in serious iron deficiency in plants. Although iron is not a component of chlorophyll, it is a necessary condition for the formation of chlorophyll, so iron deficiency blocks the synthesis of chlorophyll, so photosynthesis can not be carried out normally, which is the main cause of plant starvation and death.

In addition, iron is a component of some oxidases and plays an important role in respiration. If iron deficiency, it will affect the normal physiological activities of the plant. To solve the problem of iron deficiency, the method of watering "alum fertilizer water" can achieve good results. In addition, a small amount of black alum powder can also be added to the basin soil, the dosage is 0.5% of the weight of the basin soil, and 0.5% of 1.0% black alum water is poured every 10-15 days during the growing season, which can also ensure the iron requirements of gardenia, so that it can grow and develop normally.

Most of the soils in the north are neutral or alkaline, which leads to the lack of iron that can be used by plants, which is one of the main reasons for the yellowing of leaves. For this reason, fertile acid culture soil should be selected for the culture of Gardenia jasminoides. Generally, it can be mixed with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of sandy soil. Then per kilogram of soil mixed with 1 kilogram of sulfur powder. Watering gardenia jasminoides with big leaves is suitable to use Rain Water or fermented rice water. During the growth period, 0.2% ferrous sulfate is watered every 10-15 days or alum fertilizer water is applied every 10-15 days (the two can be carried out alternately). This can not only prevent the soil from becoming alkaline, but also replenish iron to the soil in time, thus preventing the leaves from turning yellow.

Leaf gardenia likes to be moist, in addition to the usual need to keep the basin soil moist, but also must often pay attention to increase air humidity. This is because the climate of the north is different from that of the south. The north is dry in spring, often blows dry winds, strong light intensity in summer, hot weather, and cold and dry winter. Therefore, in spring and summer, it is necessary to spray foliage with clear water every morning and evening and sprinkle water to the nearby ground to increase air humidity. Watering should be less in winter, but branches and leaves still need to be sprayed and washed frequently to keep the leaves clean.

Gardenia jasminoides likes light, but is afraid of strong light exposure. If exposed to the sun, the leaves turn yellow and whiten until they fall off. Therefore, the summer must be placed under the shade or in a place with scattered light, so that it can see some sunlight in the morning and evening, so as to prevent the leaves from turning yellow.

Gardenia jasminoides is not cold-resistant, so it is necessary to pay attention to the room and out of the room. It is generally entered in the middle of October and placed in the sunny place, and the room temperature should be kept at 10 ℃-12 ℃. It is not advisable to leave the room too early in the next spring, usually in late April. If the above four points can be achieved, gardenia jasminoides can not only settle down in the north, but also have numerous green leaves and fragrant flowers.
