How to care for gardenias in winter? How to raise gardenias in winter

Gardenia is not cold-tolerant, enter the room in mid-October, put it in a sunny place, keep the room temperature at 10 to 12 degrees, the minimum shall not be less than 0 degrees, out of the room in late April, the indoor ventilation is poor or the temperature is too high, it is easy to get scale insects, you can use a toothpick to remove, less watering, and often bask in the sun.

I tell you, pour boiling water! I don't tell ordinary people!

Hello! Gardenia cultivation method:

1. Watering. Gardenias prefer moist and moist environments, and during the growing phase from April to September, watering keeps the potting soil moist. Watering gardenias requires seasonality.

Water about 3 days in the spring. In summer, water 1 time a day in the morning or evening. Water about 2 or 3 times a week in autumn.

Control watering in winter, and use warm water when the soil is dry.

2. Fertilization. When planting and repotting, an appropriate amount of cake fertilizer or bone meal can be added to the soil as base fertilizer. In the growth period, organic liquid fertilizer can be used for fertilization, and then used after dilution, about once a month.

In spring, flower buds will grow, and fertilization can be done with potassium dihydrogen phosphate fertilizer based on phosphorus and potassium elements, about once a week, which can promote the differentiation of flower buds until the flower buds are formed. No fertilization is applied during flowering, and potassium dihydrogen phosphate can be used once after flowering, which is helpful for later growth.

3. Soil. The soil can be mixed with 4 parts of peat soil + 1 part of perlite + 1 part + 1 part of pine needle soil, the soil is rich in nutrients, strong moisture retention and water retention, soft and breathable, and slightly acidic, which is very suitable as the cultivation soil for gardenias.

4. Illumination. Gardenia likes light and is a typical strong positive flower, which needs to be exposed to sufficient sunlight in spring, autumn and winter, so that the flowering will be bigger and more fragrant. In summer, the temperature is high and the light intensity is high, so it is necessary to take good shade measures to avoid the leaves turning yellow.

5. Pruning. The main pruning time of gardenias is during the growth period from May to July and the dormant period around December, and there is no need to overprune the two stages. When the growth is relatively vigorous, the branches and leaves that are too long, too dense, and have poor growth can be cut off, which look very messy and affect the growth and ornamentation of the branches and leaves should also be pruned appropriately.

After the plant has buds, it is necessary to remove the buds that are not growing well, and keep the strong buds to ensure the quality of flowering, so that the plants can bloom large and full.

1. Control the temperature.

Although the limit temperature of gardenias is minus 12 degrees, it is still necessary to adjust the temperature to the temperature suitable for its growth when it is maintained. You can keep the growing temperature at about five degrees, and it can survive the winter smoothly. If the temperature is too high, it will wake up early, which is equivalent to breaking its growth rules and has a great negative impact on its growth.

Second, the breeding location.

In the south, it can be farmed outdoors, and in the north, it needs to be moved into a house for maintenance. If the plant is planted outdoors, you need to take measures to protect it from freezing before the cold air comes, you can wrap the trunk with waste cotton wool, or you can wrap the whole plant with plastic.

3. Ensure light.

Its leaves also do not fall and turn yellow in autumn and winter, but if the light does not meet its needs, its metabolism cannot be completed properly, and the leaves will fall and turn yellow. In winter, it is necessary to receive at least four hours of sunlight per day, and if possible, it is best to maintain it in a sunny place, which is conducive to photosynthesis.

3. Control watering.

In general, watering is done once a month in winter, but if it is warm indoors, the evaporation of water will be accelerated, so it is necessary to decide how to water the plant according to its lack of water. When watering, check the condition of the soil first, and if the surface layer is dry, you can water it, so you don't have to wait until the soil is completely dry. When watering, it is forbidden to use large water, and it should be watered slowly until the soil is completely soaked.

In addition, if you breed it now, you can use some pica foliar fertilizer to provide a nutrient basis for its future flowering.

How to raise gardenias in winter? In addition to watering and fertilizing, there are a few things to note.

1. Temperature: Gardenia is warm and filial piety, and when maintaining gardenias in winter, they need to be moved indoors higher than 5 degrees. 2. Fertilization.

In winter, the gardenia will enter the dormant period, and the demand for nutrients will be reduced, so it is necessary to stop fertilizing at this time to avoid fertilizer damage to the plants. 3. Watering: The temperature is low in winter, so you need to water gardenias every 1-2 weeks.

1. Keep warm inside

Gardenias like to grow in a warm environment, and its most suitable growth temperature is 18-22, so when maintaining gardenias in winter, you need to take warm measures for them, and it is best to move them to a warm place indoors for maintenance, and control the temperature between 5-10, so that they can safely pass through the winter.

2. Stop fertilizing

In winter, the weather is relatively cold, at this time the gardenia will enter the dormant period, at this time its demand for nutrients will be greatly reduced, so when maintaining in winter, it needs to stop fertilizing, otherwise it will make the nutrients in the soil excessive, resulting in the root system of the plant being burned, and in severe cases, it will also lead to the death of the plant.

3. Reasonable watering

Gardenia is a plant that is not resistant to waterlogging, the temperature is low in winter, and the water evaporates slowly, so it is also necessary to water it reasonably, generally every 7-10 days for it to be watered is the best, and the amount of watering can not be too large, so as not to produce water accumulation in the soil, pay attention to the water temperature and room temperature when watering.

Gardenias need to pay attention to the following in winter:

1. Soil. Gardenia likes acidic soil, in the north of the maintenance, must not use alkaline soil maintenance, cultivation can be used humus soil, vegetable garden soil, humus soil, river sand 4:4:1:1 ratio to mix, to ensure that the pot soil permeability and water permeability is better.

2. The most suitable temperature for gardenia growth is about 20-25, and the growth below minus 3 degrees will be affected, and even frostbite will die. Therefore, to maintain gardenias in the north, you must pay attention to keeping warm in winter. In indoor maintenance, it is necessary to open the window for ventilation in time to avoid excessive heat and facilitate its growth and flowering.

3. Illumination. Gardenias generally like a sunny environment, in spring and summer, gardenias should ensure at least 8 hours of sunlight, so that in winter, can survive the winter smoothly, otherwise it is very bad for wintering and growth. In the hot summer, it is necessary to avoid direct sunlight, which can be placed in a place of astigmatism, and can be transferred to a direct sunlight place in winter.

4. Fertilization. Gardenias do not like fertilizer, but they also need to be supplemented with fertilizer regularly, and the day before fertilization should also stop watering, in about 10 days can apply rotten fertilizer once, and then water thoroughly, in mid-September can basically stop fertilization.

5. Watering. The spring and autumn seasons are very dry, you can water once every three days, and you need to water after the temperature drops down in summer, you can choose to water at 17 o'clock in the afternoon, and then pay attention to water control in winter, and then water when the potting soil is dry.

1. Temperature.

The optimal growth temperature for gardenias is 16 -18, and as soon as the temperature drops, it begins to hibernate. So after winter, gardenia leaves fall off or even stop growing, don't panic, this is normal. At this point, the plant is placed at a temperature of 6 12 and allowed to overwinter naturally.

If the temperature is too low, you can wrap the pot with insulation materials such as styrofoam to protect the root system.

2. Watering. A moderately dry environment is tolerated by gardenias. If gardenias are grown in containers, they provide less water in the winter than in the summer. When watering in winter, pour some water first, and after the surface of 1-2 inches of soil is dry, water again, and the watering water is best stored for about a week.

3. Illumination. In winter, place gardenias in a cool, damp place where sunlight can be exposed, such as south-facing windows, or an artificial indoor botanical garden. If it's natural sunlight, make sure the plants stay in the sun for half a day, but keep the plants away from heating sources.

4. Fertilization. In winter, the temperature is low, and the gardenia enters the dormant period, and the amount of fertilizer is small, but because the gardenia is a typical acidic plant, the soil is alkaline and prone to yellowing, so it is necessary to apply a concentration of ferrous sulfate aqueous solution every other month or so. Note that the concentration should not be too high, and fertilization too strong will also cause the yellow leaves to burn.

5. Pruning. In winter, proper pruning is done around December, but spring is definitely not suitable because the flower buds are being bred at that time, and if you accidentally cut off the flower branches, you will cry at that time. You can cut off the weak, crossed and long branches of the upper 2 or 3 branches, and remember to spray chlorothalonil solution once after pruning to avoid wound infection.

Potted gardenias, after October (in the winter range) should be watered less, just spray with a sprayer (spray the leaves look good).To move indoors, in a sunny direction. Otherwise, you will freeze to death!

My classmate was raised in her hometown, and I asked her).After flowering in August, only water is watered, and the amount of watering is controlled, and a little more water is used than in October.
