Gardenia potted cultivation methods and precautions How to fertilize gardenias

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.

Gardenia cultivation methods and precautions:

1. Acid-loving soil: soil, water and fertilizer contain alkali, which makes the plant unable to absorb iron, and affects the formation of chlorophyll, so that the branches wither, the leaves are scorched, and even die. Use fertile, loose, well-drained acidic soil, such as mixing pine sawdust into the soil, the effect is also very good.

2 like shade: avoid scorching sun exposure, but often some people mistakenly think that gardenias require full shade, so as to cause mistakes in cultivation, in fact, pay attention to the cultivation of its cool environment at the same time, to maintain 60% of the light throughout the day, in order to meet the needs of its growth.

3. Moisture-loving: If the air humidity is lower than 70%, it will directly affect the differentiation of flower buds and the growth of flower buds, but too much humidity will cause root rot and branch withering, and leaf yellow falling off. In addition to normal watering, the foliage and nearby ground should be sprayed with water frequently to increase the air humidity.

4 Fertilizer: It is advisable to apply ripe soybean cakes, sesame sauce residues, peanut bran and other fertilizers, which can be acidic after fermentation and rotting, but must be applied with thin fertilizer, avoid thick fertilizer, raw fertilizer, and do not apply fertilizer during hibernation. If it has been planted for less than three years, it is important not to apply human feces.

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

5 Temperature-loving: 18 22 in the growth period, 5 10 in the overwintering period, and less than -10 are susceptible to freezing.

6. Timely pruning: Gardenia has strong germination power, easy to overlap branches, dense and unventilated, and nutrients are scattered. When the shape is positive, three main branches should be selected according to the shape of the tree, and other branches that have sprouted from the root tiller should be pruned at any time.

After flowering, the branches should be truncated in time to promote the germination of new branches under the cutting. When the new branches have grown three knots, the topping is carried out to avoid blind growth.

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, gardenia likes slightly acidic flower soil with good air permeability, more nutrient content and pH between 5-6. When cultivating, peat soil and humus can be evenly mixed in a ratio of 1:1 as its flower soil.

When breeding, if you find that the pH of its flower soil is high, you can add a few drops of vinegar to the water when watering and pour it into the soil together.

2. Light, it needs enough light to grow. If there is not enough light, it has the potential to grow. It can be given full sunlight on a regular basis. But in the middle of the summer, proper shading is required. Because the sunlight is very strong at this time, it is easy to burn the plants.

3. Watering, it has relatively high requirements for watering. Neither can be left unwatered for a long time, otherwise it will be dehydrated; You can't water too much water, otherwise it will cause it to rot roots. If the soil is not dry, you can first feast without watering.

If the soil starts to dry out, it's time to pour it.

4. Fertilization, it is more like fertilizer, and it can not be fertilized for a long time during maintenance, especially during the growth period, otherwise it will lack nutrients and affect normal growth. Generally, fertilizer can be applied once every half month. When applying, pay attention to apply thin fertilizer frequently, not thick fertilizer, otherwise it will burn its root system.

5. Precautions, it is best to keep it in a ventilated place in summer, which can reduce the probability of it appearing diseases and insects.

Gardenia Farming Tips:

1. Soil: Gardenia is an indicator plant of acidic soil, so the slightly acidic environment of the soil is the key to determining the growth of gardenia. The culture soil should be mixed with 7 parts of slightly acidic sandy loam laterite and 3 parts of humus. It is advisable to control the pH value of the soil in between.

Is the soil acidity alkaline? Adjust with ferrous sulfate to see if the pH is in between. Use acidic fertilizers as much as possible, and it is also good to add ferrous sulfate after fermentation in rice washing water at home.

Buy a pH test strip (2 yuan, which can be used for a long time) at the pharmacy to measure the acidity of ferrous sulfate in rice water first, and then measure the acidity of the water flowing from the bottom of the pot after watering the flowers (diluted 1:3 per week to water) as a basis for testing.

Gardenias are fertilizer-loving plants. After entering the peak growing season in April, you can top dressing once every half month (it is best to mix more water when fertilizing to prevent flower burning). In this way, it can not only meet the fertilizer needs of gardenias, but also keep the soil environment in a relatively balanced slightly acidic environment to prevent the occurrence of yellowing.

2. Temperature: The optimal growth temperature of gardenia is 16 -18. Low temperature and direct sunlight are extremely unfavorable for its growth, so it is advisable to maintain gardenias in a sparse forest or shade shed with good ventilation, high air humidity and light transmission in summer.

In winter, it should be placed in an environment with sunlight and a temperature not lower than 0, and let it dormant, as too high a temperature will affect the flowering of the next year.

3. Moisture: Gardenias like moist air, and watering should be increased appropriately during the growth period. Usually the potting soil can be watered when it is white, and it can be watered thoroughly at one time.

In summer, it is hot and dry, and it is necessary to spray the foliar surface 2-3 times a day to increase the humidity of the air and help the plants cool down. However, after the flowers have buds, they should not be watered too much, so as not to cause buds. In winter, it is better to water on the dry side to prevent the water from rotting the roots.

The needs of the soil. Gardenia likes to grow in an acidic soil environment, so when purchasing gardenia soil, pay attention to the selection of acidic soil for breeding, and pay attention to the soil pH value control between appropriate, so the choice of soil is also very important for the demand for breeding;

Suitable growth temperature requirements. According to the needs of the growth temperature of gardenias, the optimal growth temperature is 16 -18 is the best, but it should be noted that the temperature is too high or too low is not conducive to the growth needs of gardenias, so it is recommended to choose a well-ventilated indoor breeding in summer and winter, so this is also important for farmers;

Plenty of hydration. Gardenia is like a warm, humid and sunny environment, so the demand for water and the humidity of the air is also very important, during the growth of gardenia, we should pay attention to the appropriate amount of watering, but also pay attention to the gardenia foliar spray some water, can improve the humidity of the air, but also pay attention to the winter watering should not be too much, to prevent the occurrence of rotten roots;

Plenty of light time. Gardenia during the growth period, but also pay attention to the need for the right amount of light, gardenia is a plant that loves light, so it is recommended to pay more attention to increasing the light time during the spring and autumn period, and in the summer and winter, it is recommended to put the same light indoor breeding, to avoid the growth period, the temperature is too high or too low;

Appropriate fertilization and replenishment of nutrients needed for growth. Gardenia's demand for nutrients is also very high, in order to meet the gardenia's demand for fertilizer during the growth period, it is recommended to apply soybean cake, sesame sauce residue, peanut bran and other fertilizers every half a month during the vigorous growth period of gardenia, which is also conducive to more and vigorous flowers;

Gardenia is an evergreen shrub with lush branches and leaves, the leaf color is evergreen in all seasons, and the flowers are fragrant, making it an important garden ornamental plant. The following is the relevant content about the maintenance and management methods of gardenias, which I hope will help you.

The first step is to choose the right potting soil.

Gardenias prefer acidic soils, with a suitable pH of 5 to 6, so prepare suitable soil before planting. If the pH of the soil is not suitable, it will be troublesome to maintain it later.

Cultivation soil usually chooses humus soil, peat soil and half of the garden soil, do not use cinder, or directly buy special soil for Junzi orchid, which is convenient and practical.

The second step is to apply fertilizer reasonably.

Gardenias like fertilizer, and when planting, rotten cake fertilizer is added to the soil as base fertilizer.

During the growing season, it is made of cake fertilizer and ferrous sulfate, and it is watered once a week. Organic liquid fertilizer with full nutrition can also be used.

Top dressing 1 2 times at the budding stage, watering potassium dihydrogen phosphate aqueous solution, can make the flowers hypertrophied and fragrant.

When the temperature is above 35 in summer and 15 in autumn, stop fertilizing.

The third step is scientific watering.

Gardenias prefer moist and humid environments. 4 During the growing period in September, keep the potting soil moist, watering to see dry and wet, and spray the leaves at night to keep the humidity. If the plant is growing too vigorously, do not water it at night, and water it in the morning when the sun comes out.

In the northern alkaline water area, when watering, leave the tap water for one day and then water. 3 5 days, pour a little citric acid aqueous solution, can keep the leaves green.

Step 4: Get more sun.

Gardenias need plenty of sunlight to grow, and if they are left in the semi-shade for a long time, the flower branches will be thin and slender. In maintenance, except for 7 8 and noon shade and winter hibernation, other times can be maintained in the sun.

Step 5: Winter dormancy is good.

Although gardenias are hardy, potted gardenias will have damaged root systems after severe winters and will recover more slowly in spring. However, in a heated room, the temperature is high, the light is insufficient, the growth of the plant is slowed down, and the flowering is later in the second year. The best way to do this is to place the potted plants in a 5 environment and allow them to hibernate, or wrap the pots with insulation and place them outdoors in a sunny leeward place for the winter.

Step 6: Trim properly.

When the main trunk of the gardenia grows to 20 cm, it is knocked off the apex, leaving 3 4 branches, promoting the branches. After flowering every year, prune lightly and cut off weak and diseased branches. However, gardenias should not be shortened at the top of the branches in spring, otherwise it will be difficult to bloom that year.

Step 7: Change the potting soil at the right time.

Gardenias are vigorous, and the seedlings grow from a few centimeters to tens of centimeters, so they should be repotted according to the size of the plant. When the length of the branch of the plant is 2 3 times the diameter of the pot, it is necessary to repot. When changing pots, prune the old roots in time, change half of the soil, water thoroughly, put them in the semi-shade for a week, and move them to the sun after growing new shoots.
