How to raise geraniums in autumn? How to raise geraniums in winter

Autumn Orchid Planting Management:

1. Remove the yellow leaves.

Geranium after a summer of dormancy, there will be a large number of yellow leaves at the bottom, after entering the autumn, the plant begins to return to normal growth, at this time also clean up these yellow leaves, otherwise it will affect ventilation and light transmittance, and it is not good for plant growth. It is best to clean it so that the leaves do not fall into the pot and are also prone to rot.

2. Supplement phosphorus and potassium fertilizers.

If you want geraniums to bloom again in autumn, you need to fertilize them again to replenish their nutrients so that the plants can sprout and bloom again. Autumn fertilization should also be paid attention to, do not apply too much nitrogen fertilizer to it, otherwise it will promote a large number of branches and leaves, and can not bloom normally.

After autumn, it can be sprayed once a week on the foliage with potassium dihydrogen dihydrogen phosphate aqueous solution, generally used 2 or 3 times to show flower buds, and then after a period of time can open.

Wait until the plant has finished flowering, and then add some nitrogen, phosphorus and potassium compound fertilizer to the plant, so that the plant can store nutrients for the winter.

3. Do not let the potting soil be too wet.

Geraniums like dryness, not tolerant to waterlogging, although autumn is a period of vigorous growth, but the number of watering should not be too frequent, in the case of long-term excessive moisture or water accumulation in the potting soil, the root system can not breathe normally, and it will cause rotten roots and yellow leaves for a long time. Therefore, every time you water geraniums, you should wait until the potting soil is completely dry before watering, and do not water frequently to avoid waterlogging.

Fourth, increase the light in autumn.

Geraniums are afraid of strong direct sunlight, dormant plants in summer are very afraid of strong light exposure, and the leaves exposed to strong light are prone to yellowing and dry burning, so it should be shaded and sunscreened in summer.

In autumn, as the temperature drops, the intensity of the light decreases, so you can move the bonsai to the place where the scattered light hits, and then receive direct light after a while. Sufficient light will make the plants grow stronger and will also promote the flowering of pregnant buds.

In autumn, prune the geraniums with yellow leaves, apply phosphorus and potassium fertilizer to them once a week, and move the potted plants to a sunny place so that the plants can fully receive the light, and soon it will be able to sprout and bloom again.

The autumn cultivation method of geraniums is as follows.

1. Illumination. The sunlight in autumn is not very strong, so you can leave it in the sun and receive no less than 4 hours of sunlight a day. It should not always be placed in a house without light, as if the plant grows in such an environment for a long time, it is not only easy to grow, but also very likely to not bloom.

2. Pruning. The climate at this time is very stable, so its growth rate is relatively fast. There may be long branches on the plant, and there are some old and yellow leaves, and these branches and leaves that are not in good growth state should be cut off in time, which can not only promote flowering, but also make the plant shape look more beautiful.

3. Hydration. Because the plant is in the stage of vigorous growth, it is necessary to pay attention to hydrating it, and the soil used for cultivation must not be too dry. However, slower growing plants should be properly water-controlled, but not too dry, as the plants are prone to poor growth.

Fourth, fertilization. At this time, fertilizer should be properly supplemented to maintain its normal growth. Usually, fertilizer should be applied every 10 days or so, and compound fertilizer or organic fertilizer can be used.

You can also spray the plants with some potassium dihydrogen phosphate once a week. When fertilizing, be careful not to use fertilizers with high concentrations.

When geraniums come in winter, they should replace the sandy huzhao soil and mix with appropriate base fertilizer; Geraniums do not need a lot of water and fertilizer in winter, and the soil can be kept slightly moist; Geraniums need to be placed next to a window to receive sunlight; Keeping the temperature of geraniums at a constant temperature of 13 to 22 is conducive to plant growth.

When geraniums come in the cold winter, they need to replace the sandy soil, add appropriate cinders to the soil, facilitate the root ventilation of the plant roots, and add appropriate base fertilizer in the soil, and the base fertilizer generally chooses nitrogen and potassium compound fertilizer to ensure the nutrients required by the plant in winter.

Geranium is a potted plant for family ornamentation, so how to raise geranium in winter, it does not need a lot of water and fertilizer in winter, the air in winter is relatively cold, soil moisture should not be dissipated, each watering as long as the soil is slightly dry; When winter comes, the pants are buried in the bottom fertilizer in advance, so that you don't need to apply fertilizer in winter.

Geraniums are light-loving plants that are afraid of shade, and if they do not get enough light in winter, they will cause the plant to grow branches. It is best to keep the plants next to the window, and if the weather is fine, you can protect them from the cold and move them outside to receive the sun.

The most suitable temperature for the growth of geraniums is between 13 and 22, if the temperature is lower than 5 in winter, the plant base will stop growing, affecting the flowering of the plant in the second year. It is best to keep geraniums indoors and keep the ambient temperature constant in a suitable range for growth.

Geraniums like temperature and are afraid of cold, and in order to avoid frostbite, necessary cold protection measures should be taken in winter. Control the room temperature at 15 to 20 and not lower than 10 at night. When the temperature is lower, the growth of the plant will be weak, the flower buds will differentiate slowly, and the flowering will be little or no flowering.

But the temperature should not be higher than 25, which will affect its growth.

Usually place the pot in front of the sunny window and let it fully receive the light. If there is not enough light, the plant will grow wildly, which will also affect flowering. In severe cases, it will cause the flower buds to wilt and will also affect the flowering of the following year.

Geraniums are afraid of moisture and drought tolerance, and water evaporation is slow in winter, so watering should be more cautious. Normally, water once every 5 7 days, keep the potting soil dry, pay attention to the water temperature when watering, not too cold. If you water too much in winter, it will cause leaves to fall off, flower buds to grow poorly, and even rot roots to die.

Spray the foliar surface with water daily to ensure that the foliar surface is clean and can accumulate nutrients through photosynthesis.

For geraniums to bloom in winter, they need to be provided with sufficient nutrients. Apply thin liquid fertilizer once every 10 days, or water the fermented rice water.

In order to promote more flowering of geraniums with more branches, the plants should be topped several times, and lightly topped before flowering, so as to promote the increase of branching and pregnant buds of the plants. In winter, the dead flowers should be cut off in time, and the dead branches and thin branches should be cut off so as not to consume too much nutrients. However, in winter, when the temperature is low, pruning should be light so that the plant does not recover more slowly.

Growing geraniums in winter requires adequate light, suitable temperatures, prohibition of fertilization, cessation of pruning and reduction of watering.

1. Sufficient light

Geranium is very light-loving, even if it is summer all year round, as long as there is no lack of water, it must be given enough light, sufficient light photosynthesis is carried out well, the root system is developed, the flower buds are more, and the flowers can open normally, if the lack of light its buds can not open. In winter, the sun is not very hot, so it is even more important to have plenty of sunshine.

2. The temperature is suitable

The cold tolerance of geraniums is relatively poor, so the winter maintenance should be as much as possible indoors, to ensure that the indoor temperature is above 10 degrees, and at night it should be kept above 8 degrees, so that it can safely survive the winter, and if it is properly maintained, it can also bloom in winter.

3. Fertilization is prohibited

Geraniums are dormant in winter, and they cannot be fertilized at this time. Because flowers that are dormant and semi-dormant require very little nutrients. If the fertilization is done diligently, it is not conducive to its growth.

4. Stop pruning

Geranium flowering is from the top of the new branch to grow buds, because the line for its branches to grow to a certain length, it will continue to sprout buds at the same time, if just grow branches, the top will be cut off, it will go to the side branches again, not grow buds at all, so that geraniums are difficult to bloom in winter.

5. Reduce watering

Geraniums like a relatively dry growth environment, and should be watered less in winter, because too much watering plants can not absorb the roots that are easy to rot, which is not conducive to spring growth.

When cultivating geraniums in winter, it is necessary to use mixed soil containing peat, perlite, and humus, and wait until the soil is dry before watering each time, and appropriately reduce the amount of watering. Apply the base fertilizer or thin liquid fertilizer for rotting and fermentation at the time of planting, and apply a small amount of nitrogen and phosphorus fertilizer when the growth is stagnant in winter, and the growth temperature should be controlled at more than 10 degrees Celsius.

When geraniums are cultivated in winter, it is necessary to choose mixed soil containing perlite, peat soil and humus to ensure that the soil has good air permeability and drainage. Wait until the soil is dry and white before watering to ensure that the water can flow from the bottom of the pot, and reduce the amount of watering when the plant grows into winter.

When geraniums are planted, a small amount of decomposed and fermented basic fertilizer can be added to the soil, or thin stools can be used as thin liquid fertilizer, and nitrogen and phosphorus fertilizers should be applied every 1 month when the winter growth is stagnant, and carbendazim solution needs to be sprayed, and phosphorus and potassium compound fertilizers can be applied to promote the formation of xylem.

In winter, it is necessary to pay attention to the cultivation of geraniums, turn the soil every 2 or 3 months, improve the performance of ventilation and drainage, reduce the stickiness of the soil, and avoid the phenomenon of slabs, resulting in the root system being disorderly and entwined in the spring of jujube. You can also spread a layer of tiles or stones on the bottom of the soil to increase the drainage capacity of the soil.

When planting geraniums in winter, when the temperature is lower than 10 degrees Celsius, they should be moved to a warm room for maintenance to ensure that the growing environment is ventilated and has sufficient light. It can also properly prune the densely growing, senescent, weak, pest-resistant branches on the plant to reduce the unnecessary loss of water and nutrients in the plant.

Geraniums should avoid direct sunlight to reduce light in summer, try to maintain it in balconies, windowsills and other more ventilated places, maintain about 1 2 days of watering frequency rate, in addition to the normal application of potassium fertilizer other fertilizers should be stopped, so that the plant can survive the summer smoothly growth.

1. Reduce light

Although geranium is a more light-loving plant, it is necessary to reduce the light appropriately in summer, about 2 hours of light a day, because the light in summer is too strong to be irradiated for a long time, if possible, it is best to maintain it in a place where it can be exposed to astigmatism, so as to ensure sufficient light and avoid direct sunlight.

2. Pay attention to ventilation

Due to the high temperature in summer, the stems and leaves of the plant are more dense, and the stalk part is not breathable if it will increase the risk of plant disease, so it is maintained in the balcony, window sill and other places where the air is more stuffy and shouting, so that the air inside the plant can be better, which is conducive to the growth of the plant, and can have the effect of cooling.

3. Water properly

The transpiration of the plant in summer is more vigorous, so the watering should keep up, about 1 2 days in summer, you can water it once in about 1 2 days, do not sprinkle it on the leaves every time you water, to avoid burning the leaves of geraniums at high temperatures, and at the same time to avoid frequent watering of the leeches, do not let the roots of the plant accumulate water seriously, otherwise it will affect the normal growth of the plant.

4. Reduce fertilization

Try not to fertilize too much in summer, one comes to the summer plant absorption capacity becomes weaker, the second is that agricultural fertilizer is easy to burn roots and affect the normal growth of plants, in addition to the normal application of potassium fertilizer in summer, nitrogen fertilizer, phosphate fertilizer and other fertilizers should not continue to be applied, and so on in autumn fertilizer can be restored to normal.
