How to raise gardenias? How to raise gardenias

If you want to raise gardenias well, you need to pay special attention to 3 points: acidic soil; Plenty of light and regular pruning and thinning during the growing season. Doing the above three points can avoid the occurrence of yellow leaves, only long leaves without flowering, and some common pests and diseases.

1. Flower soil. The first step in making it grow well is to choose a suitable soil for it to grow in before raising it. In general, it is suitable for flower soil with a pH in between, but it is best to be in between, in addition, the flower soil needs to be soft and thick, with a certain water retention capacity and a certain aeration capacity.

Therefore, we recommend that you mix garden soil with humus soil or peat soil 1:1 to use as its flower soil. The former pays more attention to nutrients, and the latter pays more attention to water retention capacity.

2. Environment. In addition to the flower soil, we also need to give it the right growing conditions, so that it can grow better. When it comes to growing conditions, the first thing to say is moisture, this flower is a kind of flower that likes moisture, so we always ensure that its flower soil is moist, not to let the soil dry out, in addition, we can also use a sprayer to spray some water or beer around it, in order to humidify.

Let's talk about light, because it is more suitable for growing in a location with more light, so we must give it enough light in normal times, preferably half daylight.

Finally, flower fertilizer, relatively speaking, its demand for flower fertilizer is still relatively large, whether it is growth and development or flowering are inseparable from the support of nutrients, but everything is too much, once the flower fertilizer is too much, the plant has no time to absorb, the remaining flower fertilizer will be stranded in the flower soil, which is likely to cause root burning.

3. Skills. In addition to giving it the right growing conditions, we also need some means to help it grow better

The first one is pruning. Many friends think that it only needs to be pruned before and after flowering, because pruning before flowering can make it bloom more and more colorful, and pruning after flowering can help it recover quickly. In fact, we also need to prune and prune its leaves in ordinary times, so that we can remove some useless flower branches in time, reduce nutrient consumption, and help it remove diseased leaves and prevent the spread of some diseases.

The second is to change the pot, the flowers that have been raised for many years do not grow well because they have not been repotted. Repotting it will not only increase its growth space, but also give it new soil and provide more nutrients to make it grow better.

Gardenias like a cool, humid environment, but can not be without sunlight, nor can they be exposed to the sun, so it is best to put it in a sunny room, the air humidity is not too dry, it is best to sprinkle water on the leaves every day or sprinkle water on the ground or put a basin next to it; It prefers acidic soil, so it is best to use rainwater or rice water to ferment for a period of time before using it; Pelvic ventilation should be good.

If you want to learn how to raise gardenias, you must first create a suitable environment for gardenias, acidic soil is the most conducive to growth, maintain sufficient light, pay attention to watering problems and correct fertilization, pay attention to the temperature can not be too cold or too hot, and then prune in time in summer and autumn, you can maintain it perfectly.

1. Gardenia is an acidic flower, the appropriate pH value is between 5 and 6, if it is cultivated with alkaline soil, then there will be many problems in the cultivation process. So it's best not to dig up some soil and use it to raise gardenias, we can use some humus, peat soil or sawdust and half of the garden soil to prepare it ourselves. If you really can't do it, you can go to the flower market and buy special soil for gardenias.

2. Many flower friends mistakenly think that gardenias like a cool environment, so they make mistakes in cultivation. Gardenias need a semi-shaded environment, which can be fully exposed to light in daily maintenance, and only need proper shade in the summer when the weather is hot and the temperature is high.

3. Gardenia is generally watered once every 3 days in spring, and when the weather is hot in summer, the water evaporates quickly, and it needs to be watered every day, and it is required to be watered in the morning. In autumn, you can water once every two days, and in winter, you can master the principle of not drying and not watering, because the temperature is low in winter and the water evaporates very slowly, and watering too often can easily lead to root rot.

4. Gardenia needs fertilizer during the growth period is very vigorous, every 10 days or so to apply a water-soluble fertilizer of Trim, 1 day before fertilization should stop watering, fertilization of this day at the same time watering 1 permeable.

5. If you want to know how to raise gardenias, the right temperature is also very important. The suitable temperature for gardenia growth is 20 30, so it is necessary to do a good job of protection in time in summer and winter to avoid gardenia being sunburned or frostbitten.

6. Gardenias need to be pruned twice a year, once in May and July in the spring, and the other in December in the winter, these two time periods are the least harmful to gardenias. When pruning, in addition to the shape, it is best to prune the opposite leaves at the end of the branches, and the residual flowers should also be cut off, so that more vigorous flowers will bloom in the next year.

1. Acidic soil.

Gardenias prefer acidic soils, so when maintaining them, it is best to pay attention to the pH value of their soil between 5 and 6. Generally, humus soil, peat soil and half of the garden soil can be prepared, do not add coal, otherwise it is not conducive to growth.

2. Semi-shady environment.

Gardenias prefer to grow in semi-shaded environments, so don't let them get direct sunlight, but they can't be completely devoid of sunlight, and half shade is required. Otherwise, the leaves will also be stunted.

3. Watering frequency.

Gardenia likes to grow in the environment, in the summer when the temperature is too high, it should be watered every day, remember not to water at noon, so as not to cause the gardenia to burn roots. In spring and autumn, water is thoroughly watered once every two days, and in winter, it is necessary to control the water and master the principle of not drying and not watering.

4. Appropriate fertilization.

Gardenia likes fertilizer, so in the process of its growth, it is necessary to use cake fertilizer and ferrous sulfate to make alum fertilizer water once a week, and you can also use humic acid full nutrient organic liquid fertilizer. It is time to apply an aqueous solution of potassium dihydrogen phosphate to promote the blooming of more flowers.

5. Prune after flowering.

After each flowering, the gardenia should be pruned in time, because flowering will consume a lot of nutrients, if you do not prune off its dead branches, old branches and long branches in time, then it will compete with the normal plant for nutrients.

2. Precautions.

1. Winter dormancy.

Do not fertilize the gardenia in winter and do not move it too much so as not to break its dormant period. In winter, gardenias are in the dormant period, and only when they are dormant will they grow more vigorously and produce more beautiful flowers in the next year.

2. Replace the potting soil.

In the process of gardenia maintenance, to observe its growth, if the pot can no longer accommodate the growth of gardenias, then it is necessary to replace the pot in time, and the soil should also be replaced, at least half of the old soil should be removed, and then replaced with new soil.

3. Shade in summer.

Since gardenias will grow better in a semi-shady environment, when the weather is hot and the sun is very strong in summer, it is necessary to pay attention to moving them to the shade for maintenance, and pay attention to shading, so as not to cause gardenias to be burned by the sun.

Soil. Mast flowers like to grow in acidic soils with a lot of humus. It can be prepared according to 4 parts of humus soil, 4 parts of vegetable garden soil, 1 part of soybean meal (rotted) and 1 part of river sand, with good water permeability and air permeability, and then mixed with alum or sulfur.

2. Temperature. Gardenia in 20-25 is its optimal growth and development temperature, flowering temperature is 26-28, after 4-5 years of cultivation of plants, can tolerate a short period of -3 low temperature, -5 below that suffer frost damage, leaves black after falling off, young shoots freeze to death. In winter, indoor maintenance should be maintained at 6-10 degrees, and the minimum should not be less than 0.

If the room temperature is higher than 15, the south-facing doors and windows should be opened, properly ventilated, and the temperature should be reduced, otherwise it is easy to cause germination, and it will be harmed by low temperature, which is extremely unfavorable to the growth and flowering of the next year.

3. Illumination. Gardenias like abundant light, especially in spring and autumn, to give more than 8 hours of sunshine a day, otherwise it is not conducive to its growth and development and winter overwintering. In summer, avoid strong light exposure at noon, otherwise the leaves will turn yellow, and it is necessary to place astigmatism for maintenance, and the light transmittance is 40-50.

In winter, it is placed indoors in direct sunlight facing south.

4. Fertilization. Gardenia is not a very fattening flower, but because it grows vigorously and is limited by the nutrients of potting soil, it needs to be reasonably supplemented with fertilizer during the growth period. Apply rotten human manure or cake fertilizer every 10 days or so, stop watering 1 day before fertilization, and water once at the same time on the day of fertilization.

Fertilization will be stopped from mid-September. For adult plants, apply sesame paste residue once in mid-June and mid-August, two at a time, and mix well with the topsoil after crushing.

5. Watering. Gardenias like big water, and some people call it "water gardenia". In spring, due to the windy winds, dry air and scarce rainfall, water is watered every 3 days, and water is sprinkled every morning and evening around the potted plants to increase air humidity.

In summer, when the weather is hot, it is necessary to water less in the morning and water thoroughly after 2 o'clock in the afternoon. In summer, it is advisable to water with soft water, because the hard water contains more calcium and magnesium salts, which is very unfavorable to the growth of gardenias. In order to overcome the alkalinity of the soil and water quality, alum fertilizer is watered once a week during the growing season to keep the gardenia branches and leaves thick.

Watering should be controlled in winter, not dry or watering, long-term excessive water content, easy to cause root rot and death.

6. Topping. In order to regulate and control the growth of gardenias, make the plant beautiful and promote flowering, the top of the new branches is removed when the vigorous growth is about to stop in the spring, so as to promote the fullness of the axillary buds at the base of the branches and the formation of flower buds.

It used to be very lush, with buds waiting to be released, and the flowers were blooming, and the fragrance was pleasant. There are only two reasons for the sudden occurrence of this situation: first, there is too much watering, and the roots are not well ventilated, causing the roots to rot.

Second, due to negligent management, the soil is too dry, the root system is over-damaged by transpiration pull, and the ability to deliver nutrients and water to the leaves and flower buds is lost after watering. These two reasons are important reasons for the rapid withering of leaves and buds, and I have finished answering.

Here's how to raise a gardenia:1. Gardenias should have full sunlight, because gardenia is a plant that needs sunlight very much, whether it is the healthy growth of its leaves or the opening of flowers, it is very much in need of sunlight.

2. Gardenia is a very water-loving flower, also known as "water gardenia", and it should not be allowed to be excessively short of water when maintaining.

3. Open more windows for ventilation, air permeability is very important, and spray fungicides and insecticides every half a month or so to prevent pests and diseases.

Gardenias are best planted in the ground, and if they are planted in pots, they should be repotted every two or three years. That is, to change the soil, it needs to find some humus soil and add some red soil in the acidic soil. It's better this way, it needs a lot of sunlight, and it needs a lot of water and fertilizer.

Gardenia leaves are bright green, evergreen in all seasons, the flowers are big and white, fragrant and fragrant, with edible and medicinal value, pick a few gardenia omelette during the flowering period, and you can also make a gardenia tea in winter, which has the effect of beautifying the skin, moisturizing the intestines and laxative!

Gardenias are raised like this:

1. Soil: Gardenia likes to grow in an acidic soil environment, and the pH value of the breeding soil should be controlled between. It is best to use fertile, loose, well-drained acidic soil, such as mixing pine sawdust into the soil.

2. Temperature: The best growth temperature of gardenia is 18 22 is the best, and too high or too low temperature is not conducive to the growth of gardenia. In summer and winter, choose a well-ventilated indoor breeding, avoid summer exposure, overwintering period 5 10, less than -10 is susceptible to freezing, keep warm in winter while giving gardenias more sunlight during the day.

3. Moisture and humidity: Gardenia likes a warm, humid and sunny environment, during the growth period of gardenia to increase the amount of watering appropriately, often spray some water on the leaf surface and ground of gardenia, which can improve the humidity of the air, air humidity below 70% will affect the differentiation of flower buds and the growth of flower buds, too wet will cause root rot and branch withering, leaf yellow falling off. Therefore, it is not advisable to water too much in winter to prevent root rot.

4. Sufficient light: Gardenia is a plant that loves light, and spring and autumn are the growing seasons of gardenias, increasing the light time. In summer and winter, it is recommended to put it into indoor cultivation with light to avoid that the temperature is too high or too low during the growth period is not conducive to the growth of gardenias.

5. Fertilization: Gardenia likes fertilizer in the vigorous growth period, apply soybean cake, sesame sauce residue, peanut bran and other fertilizers every half a month, which is conducive to the blooming of more and more vigorous, avoid thick fertilizer, raw fertilizer, and do not fertilize during the hibernation period. If it has been planted for less than three years, it is important not to apply human feces.

Excessive application of nitrogen fertilizer will result in thick branches, large leaves, thick green, and no flowering. When phosphorus and potassium fertilizers are deficient, there will also be no flowering or wilting and falling off flower buds.

6. Pruning: Gardenia during the growth period is easy to overlap the branches, dense and not ventilated, so it is necessary to prune the branches appropriately, which can promote the growth very well, cut off the redundant branches and leaves in April to protect the flower buds, and then cut off the residual flowers after flowering in June to promote the extraction of new shoots, and when the new shoots grow to 2 to 3 knots, they should be topped and wiped off part of the axillary buds.
