It is beneficial for moisturizing, but the temperature in the bag should be prevented from being too high. Gardenia water rooting, such as cuttings rooting normal, root length of more than 1 cm, it is necessary to separate the pot in time. If the thin board is inserted with water, gently split the board and take out the cuttings. If the water is inserted in bundles, gently separate the cuttings. When planting, soil shall be built slowly and lightly. Don't hurt the root. After planting, it should be watered thoroughly and cultivated in a sheltered and shady environment.
Gardenia is mainly propagated by cutting, or by layering, branching or planting. In the north, it is better to use peat soil and surface sand to mix the substrate for pot planting in April and May, and place it in the shade shed to scatter light, so as to keep the substrate transparent and the environment fresh and moist(5 gallon pots for plants). It takes about 40 days to root and survive, and then it is planted separately in the pot. A small amount of family breeding can be done in summer with a big bottle of water. How to raise Gardenia in the north? Potted Gardenia in the north must be finely prepared into acidic culture soil.
Gardenia should choose a square or round glazed pottery basin, which is slightly shallow, and a thousand tube basin is used for cliff style. Potting usually uses rotten leaf soil or weathered pond soil, which will be transplanted in March to April. When planting, part of the branches and leaves can be cut off, sufficient base fertilizer can be added at the bottom of the pot, and the pot will be placed in shade after planting. Gardenia can be made into curved dry, inclined dry, straight dry and cliff type shapes, with small and medium-sized bonsai in the majority. The whole posture processing of Gardenia jasminoides Ellis should be carried out after flowering, and the dormancy period is also possible.
Move indoors in winter and keep the room temperature above 5 ℃. During the growth period of gardenia, attention should be paid to watering and fertilizing, and when appropriate, redundant branches should be pruned. Gardenia should be turned over once every 2-3 years, usually in February to March. When the growth is vigorous in July, it should be pruned once, and the top tip should be cut off to promote branching, so as to form a complete crown. Gardenia should avoid waterlogging. After rain, the water in the basin should be removed in time to prevent rotting roots.
Gardenia jasminoides Ellis prefers warm and humid climate, the suitable temperature is 22~28 ℃, and the relative humidity is required to be above 70%. It is resistant to light frost but not cold. It is suitable for pot planting in the north of Huaihe River(garden pots wholesale). It likes soft and sufficient light. In the high temperature season, it is required to be shady, avoid water for a long time, and the fertilizer level is required to be stable and appropriate. The length of the lower end of the planting strip immersed in water is about 1/2 of the length of the cutting strip. The water containers and water shall be clean and free of oil stain, and the water shall be changed once every 1-2 days.
It can also be used as a bonsai. Gardenia likes light, slightly resistant to shade; It likes warm and humid climate and is suitable for planting in fertile, loose and well drained acid soil. It is afraid of cold and likes fertilizer. Generally, peat soil, pine twig soil and surface sandy soil are mixed, and an appropriate amount of oil meal or dried dung powder and 0.1% sulfuric acid powder are added. The fertilizer is piled up for a period of time to blend with the soil for use in the basin or when changing the basin. A small amount of family cultivation can be purchased and sold in bags of southern flower and tree cultivation soil.
Prevent plant damage and yellowing caused by hot sun and rainstorm. Acidic organic liquid fertilizer should be used for topdressing during the growth period, and the thin and decomposed liquid fertilizer can be applied every 15 days before flowering. During the flowering period, stop topdressing, and pay attention to proper watering and looking for water to prolong the flowering period. The seedlings are shade tolerant and the adults like sunshine. Under the condition of sufficient sunshine, the plants are short and strong, grow big and bear many fruits. But be afraid of exposure to the sun, otherwise the leaves will turn yellow and white until they fall off.
Family farming can be irrigated with fish tank water or cold boiled water. In order to prevent basification of basin soil, it is better to turn the basin and change soil once a year, which is more effective(reusable seed starting trays). Gardenia has elegant appearance, bright green leaves, evergreen all the year round, white flowers in summer, white flowers, and pleasant fragrance. It is a good tree species for watching flowers and leaves. The bottom hole of the flowerpot shall be enlarged, and bricks and tiles shall be used as the drainage layer. Make sure that there is no water at the bottom of the basin. Watering shall be carried out timely and appropriately to keep the soil moist.
Gardenia can be propagated by cutting, layering, branching and sowing. The branches are inserted into the paddy field or water to take root, and then moved to the seedbed for cultivation, that is, the water insertion method. Select the tender branches or semi mature branches of the year, cut them into about 10 cm branches as cuttings, leave 2~4 leaves at the top, cut all leaves at the bottom, and cut the base into a horseshoe shape. Gardenia like warm climate, drought but not cold.
The suitable temperature for the growth and development of Gardenia jasminoides is 23~28 ℃, and high temperature and heat in summer are unfavorable to the growth. Gardenia is mainly planted in pots or indoors in northern areas. The cold resistance is good, and the gardenia can survive the winter outdoors. Although the cold resistance of potted gardenia is slightly poor, it can also survive the winter safely at no lower than 0 ℃. When it is cold, move indoors or bury the pot in the soil at leeward and sunny places. Sunshade and cool down properly in summer when the temperature is high.
Potted gardenias should be placed indoors in winter. They are slightly cold resistant, but their leaves will freeze when the temperature is below - 12 ℃(1 gallon nursery pots bulk). Gardenia jasminoides is in a semi dormant state in winter, and the room temperature should not be too high, generally maintained at 3~5 ℃. Watering shall be controlled. Watering shall be carried out only when the soil surface is dry. Watering shall be carried out thoroughly with less frequency. Do not be wet or dry. Spray water frequently to keep the surrounding environment moist. Pay attention to shade during hot summer.
The flowerpot should not be placed in the sunny window, but should be placed in a cool indoor place. The light can reach half light, but it should be ventilated. Gardenia likes fertilizer, but it is better to apply thin fertilizer frequently. After the pot is changed or the pot is put on in May, ferrous sulfate water shall be applied once. The propagation of Gardenia jasminoides Ellis can be conducted by cutting or layering. The water insertion method is the most convenient and fast method. Floating foam board and bucket can be used as materials, and the survival rate is very high.
The cultivated Gardenia jasminoides jasminoides is prone to yellow leaves. If the leaves are watered with light ferrous sulfate water below 0.2% for 2-3 times, the leaves will turn green. In summer, water more to increase air humidity and make the flowers and leaves grow well. At the same time, gardenias should be placed in shade to avoid exposure to the sun, or the leaves will get sunburn. Gardenia is most suitable for transplanting in spring. In the south, it can also be cut in plum rain season, and soil must be taken for ground planting.
In summer, water more to increase humidity. Apply more thin fertilizer before flowering to promote flower hypertrophy. Shaping and pruning should be carried out in early spring, and excessive branches should be cut off in time. Move to the sun for curing after it is cool in autumn. In winter, put it in a bright place(square planters wholesale). The temperature should not be too high. Pay attention to keeping the air fresh and moist. In order to prevent the leaves from yellowing, 1/300 ferrous sulfate aqueous solution or grass soaking in water can be applied once in the peak growing season for 7-10 days.
The pot soil for Gardenia jasminoides cultivation should be acidic, and the pH should be between 4.0 and 6.5. It can be made by mixing 7 portions of slightly acidic sandy loam soil and 3 portions of rotting leaf soil. If the pot soil is alkaline, it will suffer from yellowing disease. The seedlings shall be planted in small pots, and gradually replaced with large pots. It is better to replace the pots when the crown width is 2~3 times the diameter of the pots. After the pots are poured, the new pots shall be planted with soil lumps, and the diameter shall be 5~10cm larger than the original pots.
Generally, when the flowerpot reaches about 30cm, it will not be changed. The pot soil can be changed once every two years. The method is: after pouring the pot in early spring, cut off some old roots, shake off half of the old soil, mix new soil with a proper amount of decomposed organic fertilizer and put it at the bottom and side of the pot, plant it in the pot, pour it through water, put it in the shade, and move it to the sun for curing when there are new buds sprouting. The best temperature for the growth of Gardenia jasminoides is 16~18 ℃.
The cultivation method of Gardenia jasminoides is light. Gardenia jasminoides enjoys both light and shade. Its leaves are bright green in shade, but its flowering is slightly poor. In summer, if exposed to the sun on the balcony, it is easy to cause the branches and leaves to turn yellow. Even wither and die, the plant can be moved indoors or under the shade(microgreen trays bulk). In spring and autumn, you should be fully exposed to light outdoors. Gardenia flowers are placed on the top of the stem. In the growing season, top pinching can be properly carried out to promote the growth of lateral branches. Increase the number of flowers.
Keep the pot soil moist during the growing season, but after the bud appears, do not water too much to avoid bud falling. In winter, it is better to dry the pot soil properly to prevent the root from rotting too wet; In hot and dry summer, spray the leaves 2-3 times a day to increase the air humidity. Pot planting requires acid soil rich in humus, loose and fertile, with strong permeability and pH value of 5-6. Gardenia jasminoides Ellis and Gardenia Juglans are most sensitive to soil pH value.
The best way to water Gardenia jasminoides is to use stored rainwater, or add 100g ferrous sulfate (alum) to 5000ml water to improve the water quality. When the PH value is above 6.5, the leaves begin to turn yellow, and then fall off piece by piece from bottom to top, with strong resistance to sulfur dioxide, etc; It strives for the role of air, but it is afraid that smoke and dust pollution will cause dry, dry and yellow leaves. Fertilization of Gardenia jasminoides Ellis.
In budding stage, the flowers can be plump and fragrant if they are watered with 0.1% potassium dihydrogen phosphate solution for 1~2 times. Fertilization shall be stopped when the temperature is above 35 ℃ in summer and below 15 ℃ in autumn. Disease and Insect Control of Gardenia jasminoides Ellis L. In summer, when the temperature is high and the ventilation is poor, the gardenia jasminoides Ellis L. is prone to scale insects, red spiders and soot disease(15 gallon plastic pots wholesale). Household maintenance can be manually brushed or sprayed with detergent solution, which has a certain prevention effect.
Gardenia jasminoides is usually propagated by softwood cutting. The method is simple and has a high survival rate. In the south, 10~12cm softwood is usually used as cuttings in the plum rain season. It is required to be strong, with 3~4 leaves on the top, and the following leaves removed and planted on the seedbed. It can also be watered in summer. The method is to insert the cuttings one by one on a round racket made of reed stalks and float in the pond to naturally take root and survive, and then go to the basin for curing.
Generally, the planting pit used for cutting flowers and public viewing is about 50cm deep and wide, and it is better to plant in the dormant period. 3% of the decomposed cake fertilizer can be added to the cultivated soil as the base fertilizer. During the growing season, the cake fertilizer and the alum fertilizer water retted with ferrous sulfate can be watered once a week. The cultivation method of Gardenia jasminoides Ellis is generally pruned in spring, and the long redundant branches, weak branches and other random branches that affect the plant shape are cut to maintain the beautiful plant shape.
At the same time, cut the hollow branches in the dense chamber. Soak the base with 0.1% potassium permanganate solution for 10-20 hours or put the base in ABT rooting powder for 10 hours before cutting, then insert the cuttings into a brown glass bottle or other container containing water, let about 1/3 of the base of the cuttings soak in water, and then put it in a dark place(6 inch pots wholesale). After rooting, gradually move to a place with light, and change the water every other day. It takes about 20 days to grow new roots.
Gardenia bonsai should be placed in a place with half yin and half yang and moist air. The open field cultivation of Gardenia jasminoides has strong adaptability, extensive cultivation management and easy success. It is better to choose the acid and slightly acid soil with fertile, loose soil and good drainage in the area facing the sun but not easily exposed to direct sunlight. The technical requirements for land preparation, compartment opening and base fertilizer application are the same as those for other flowers. The row spacing of plants to be planted depends on the use of gardenia production.
If it is necessary to plant in the growing period, it is better to carry soil mass to ensure survival. After planting, timely pour root setting water, and keep relatively high air and soil humidity, but do not accumulate water to avoid rotting roots. It is necessary to strengthen the management of fertilizer and water before flowering of pregnant buds, and implement the principle of thin application and frequent application. The shaping and pruning of Gardenia jasminoides are usually carried out in early spring. After each new shoot is pulled, it is necessary to pick the heart. One branch divides into three branches, forming a quick crown and many flower branches.
When the flowers in each season are about to wither, the residual flowers should be removed in time, which is conducive to flower bud differentiation in the next season, and more and better flowering(1.5 gallon pot). The water in the basin shall be emptied in time after rain. Plastic pruning is the same as open field cultivation. Gardenia potted cultivation soil is mostly made of 5 portions of vegetable soil, 3 portions of decomposed compost and 2 portions of sand. In addition, some sulfur powder (very little) can be added, or it is better to use the rotting leaf soil in the mountain forest.
In most areas of Guizhou Province, pots are put on or changed before germination in spring. Generally, pots are changed every 2 to 3 years, and basal fertilizer is needed when changing pots. The management of potted gardenia is basically the same as that of ground planting. Gardenia prefers a warm and humid environment. It should not be dry. The suitable temperature for growth is 22~25 ℃. Watering should be dry and wet at ordinary times. At the same time, ponding in the basin should be prevented. In addition, it is necessary to spray water on the blade surface frequently, usually once a week, to keep the blade surface clean.
Potted gardenias like sunshine, but they are afraid of strong light exposure. Therefore, it is best to cultivate them in a place with scattered light in summer, so that they can see more sunlight in the morning and evening as much as possible, so as to avoid yellowing their leaves in a high temperature, high humidity and shaded environment. Top dressing can be applied once every 7-10 days before flowering in the vigorous growth period. Spray the leaf surface and ground with clean water in the morning and evening to increase the air humidity of the pot planting field. The growth is slow in late autumn and early spring, with topdressing once every 2-3 weeks.
When the basin is changed in spring, sufficient decomposed organic fertilizer should be applied(plastic bonsai pots wholesale). During the growth period, the amount of liquid fertilizer should be increased, and it is better to use concentrated alum fertilizer water (one part of the original fertilizer liquid plus three parts of water). In the growing season, if the leaves appear yellowish and grow weakly, spray the leaves with 5% black alum dilute solution once a week until the leaves and new buds appear strong green. However, attention should still be paid to the management of water, fertilizer, light and air in the basin soil, otherwise it cannot be consolidated.
Watering and fertilization should be carried out when the basin soil is dry (it cannot wait until it is absolutely dry). If the basin soil is large, cloudy or severely defoliated, and the basin soil moisture is not thousand for many days, watering and fertilization should not be carried out. Ventilation should be improved, and the lighting time should be increased to make the basin soil dry as soon as possible. It should be well lit and ventilated, and should not be placed in the shade or indoors for a long time, which will affect its photosynthesis, transpiration and root respiration, resulting in weak growth, and then withered leaves and yellow branches.
Often spray the branches and leaves and the vicinity of the flowerpot to keep it moist, but do not water the basin too much. Try to see the wet. If necessary, although it is a cool hot day, water it every other day. During posture modification, the trunk is processed by climbing, and the other branches are processed by pruning. In June, cut the branches in time after the flowers wither. When the petals change from white to yellowish brown, cut them off in time. When cutting, keep 2 to 3 knots at the base, so as to promote the base to sprout new branches.
Increasing the application of organic fertilizers rich in nitrogen, phosphorus, potassium and calcium can improve the absorption and utilization of iron and nitrogen fertilizer, but do not apply plant ash containing potassium(72 cell plug tray). Gardenia likes fertilizer, and it is best to change the pot once a year. In addition, except in winter, it is better to apply the thin and decayed quick acting fertilizer once every half a month. When the buds appear, the quick acting fertilizer mainly consisting of phosphorus and potassium can be applied, such as 0.1% ～ 0.2% potassium dihydrogen phosphate or 0.3% ～ 0.5% calcium superphosphate.
