What do you need to pay attention to when planting gardenias?

What should I pay attention to when maintaining gardenias?

Gardenias prefer warm, humid climates and slightly acidic soils and waters, making them suitable for living in the south.

1. Choose acidic potting soil.

The appropriate pH is 5 to 6. Cultivation soil can be humus, peat soil or sawdust plus half of the garden soil, avoid the use of old wall soil and cinder.

2. Water frequently.

Water the surface of the potting soil when it is dry, and use a watering can to pour water on the foliage at night. If the growth is too vigorous and the internodes are long, do not water at night, and water again in the morning when the sun comes out.

3. Fertilize frequently.

In the culture soil, 3 rotting cake fertilizer can be added as base fertilizer. In the growing season, the alum fertilizer water made of cake fertilizer and ferrous sulfate is watered once a week, and the potassium dihydrogen phosphate aqueous solution is watered 1 to 2 times during the budding period, and the fertilizer is stopped when the temperature is above 35 in the summer and below 15 in the autumn.

4. Likes humidity and sunshine.

Gardenias love light and can grow in semi-shade for a long time, but it is necessary to maintain 60 years of light throughout the day to meet its growth needs.

5. Good dormancy in winter.

Gardenias suffer damage to their roots after harsh winters in the north and only recover in spring. Therefore, it is necessary to wrap the pots with insulation materials such as styrofoam, protect the root system, and place them in a leeward and sunny place for winter, so that the spring recovery is fast and the flowering is early.

6. Change the potting soil in a timely manner.

When the crown width of the family potted plant reaches about 28 cm, change the potting soil, and if it is a pot, plant the soil mound into a new pot. It is better to change the soil in March in the spring.

7. Trim properly.

According to the shape of the tree, the three main branches should be selected, and the other branches that sprout from the root tiller should be cut off at any time. Remember that gardenias should not be shortened in spring, otherwise they will not bloom that year.

What to do if gardenia leaves turn yellow?

The yellowing of gardenia leaves is more common and is caused by a variety of reasons, and different measures must be taken to prevent and control it

1. When iron is deficient, the veins of young leaves lose green and yellow, which will make the whole leaf yellow, and even scorched leaves and branches wilt, and finally cause the death of the plant.

In this case, the aqueous solution of ferrous sulfate that can be sprayed can be prevented.

2. The yellowing disease caused by magnesium deficiency begins to develop from the old leaves to the new leaves, and the leaf veins are still green, and the leaves fall off and die in severe cases.

In this case, boron and magnesium fertilizer can be sprayed to prevent and control. Excessive watering, freezing, etc., can also cause yellow leaves, so special attention should be paid in the maintenance process.

In addition, nitrogen deficiency is manifested as simple leaf yellow, and the new leaves are small and brittle;Potassium deficiency is manifested by the transformation of old leaves from green to brown;Phosphorus deficiency is manifested by the purplish-red or dark red color of the old leaves. Prevention and control can be carried out in a targeted manner.

Gardenias, suitable for planting in front of steps, poolsides and roadsides, can also be used as hedges and potted ornaments, flowers can also be used for flower arrangement and wearing decoration.

In addition to being ornamental, gardenias, leaves, and fruits are beautiful, and the flowers are fragrant, and can be used to smoke tea and extract spicesThe fruit can be made into yellow dye;Roots, leaves, and fruits can be used as medicine;Gardenia wood is solid and fine enough to be carved.

Potting soil is transparent: It is mixed with humus soil, vegetable garden soil and river sand to make culture soil. Temperature Requirements:

Scientific fertilization: Gardenia peanuts are applied once at an interval of 10 days for a long time.

If the room temperature is higher than 15°C, the south-facing doors and windows should be opened, and the temperature should be properly ventilated to reduce the temperature. Otherwise, it is easy to cause germination, and it will be damaged when it encounters low temperatures, which is extremely unfavorable for the growth and flowering of the next year. 3. Light.

Gardenias like abundant light, especially in spring and autumn, and should be given 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 advisable to place astigmatism for maintenance, and the light transmittance is 40-50%. In winter, it is placed indoors in direct sunlight facing south.

Gardenias generally bloom in the sweltering summer, after a heavy rain, the feeling of being hot and stuffy, you will smell a burst of fragrance. Then you will see that the flowers in the garden are still budding in the morning, and they are all in full bloom, and each flower is very fragrant under the moisture of the rain. The flower language of gardenia is "strong and eternal love, a lifetime of love waiting for us", which is a very beautiful sustenance.

Light is very important for the cultivation of gardenias. Gardenias prefer shade. It must not be exposed to strong light, otherwise it can be easily burned by strong light, especially in the hot summer.

We must keep the gardenias in a cool environment. In autumn and winter, it can be placed where there is enough scattered light. Gardenias grow well in this environment.

Gardenias prefer a warm and humid environment, are heat-tolerant and cold-tolerant, and prefer light and shade. The suitable temperature for the growth of gardenia is 16 22 °C, the temperature is too high or too low is not conducive to the growth of gardenia, more than 5 °C can be safely wintered, and below -3 °C is subject to frost damage. Gardenia likes light but avoids strong light exposure, and its leaves are dark green in a shady environment, but the flowering is poor; In spring and autumn, the light time can be increased, and in winter to ensure the light at the same time, pay attention to shading and heat preservation, and try to maintain half a day in a cool environment, which can better meet its growth needs.

Gardenias like fertility, loose soil, smooth drainage, grow in alkaline soil and tend to turn yellow, is a typical acidic plant. When planting, soak the roots of gardenia seedlings in water, change the water once a day, and only after a week can they be potted. Spread a layer of bricks and tiles at the bottom of the pot to facilitate drainage, then add a layer of soil.

Place the gardenia seedlings in a pot, continue to fill the soil, and then gently compact the soil and water it thoroughly. Gardenia is fertilizable, and it is necessary to apply top dressing frequently, fertilize with a fertilizer with a lower concentration, or water ferrous sulfate or alum fertilizer every 10 15 days, which can avoid the soil turning alkaline, add iron to the soil, and avoid yellowing of the leaves of the plant. Before flowering, phosphorus and potassium fertilizers should be applied 1 or 2 times, which can promote the growth of flowers.

When planting gardenias, you need to pay attention: when the temperature is too high, avoid strong light exposure to prevent sunburn to new leaves.

Do not use alkaline fertilizer for gardenias to prevent alkalizing of the potting soil.

If the temperature is too low, it is necessary to prevent freezing.

It is especially intolerant to waterlogging and avoids heavy watering.

Pay attention to the use of fertilizers, as good fertilizers can better promote the growth of gardenias. Pay attention to the frequency of watering, as gardenias have very high water requirements.

Gardenias prefer warm, well-ventilated, well-lit, and humid environments, and have poor cold and drought tolerance, so pay attention to temperature and moisture when cultivating. It is usually best to keep it in a bright and warm place. It likes to fertilize, and it needs to be topdressed in time during the peak growing season, which can be done with thin fertilizer.

Its growth also has high requirements for the soil, so it is necessary to pay attention to the soil mix to ensure that the soil is soft, breathable, fertile and acidic.

First of all, when planting, we must choose the soil is more fertile and wide land, and in the process of fertilization, we must use farmhouse fertilizer, do not use fertilizer bought outside, but also often water the plants, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time. And you can also spray less pesticides on the plants.

Flower soil. The same amount of sandy loam soil can be mixed with peat soil as flower soil.

Light and temperature. In summer and early autumn, give proper covering. The suitable temperature for growth is 18-22 degrees Celsius, and the temperature is 5-10 degrees Celsius for safe wintering.

1. Potting soil selection: mix humus, garden soil and peat soil for use. 2. Watering method:

When watering gardenias with tap water, you need to leave them for 2-3 days before using them. 3. Planting environment: Gardenia should be exposed to sunlight for at least 8 hours a day.

4. Prune in time: During the dormant period of the plant, all the diseased branches, weak branches and overlapping branches should be cut off.

1. Potting soil selection

When planting gardenias, it is usually a mixture of humus, garden soil and peat soil, and pay attention to the pH value of the soil, generally in between, and choose a mud pot with good ventilation and drainage function for the flower pot.

2. Watering method:

When watering gardenias, be careful not to use tap water for direct watering, you need to place it for 2-3 days before using it, so that the harmful gases in it can fully volatilize, and when the air is dry in summer, you should often want to spray water mist on the foliar surface to improve air humidity.

3. Planting environment

Gardenia is a very light-loving flower plant, during the maintenance period to ensure at least 8 hours of sunlight per day, but pay attention not to direct sunlight, winter gardenias will generally enter a dormant state, need to be placed in a warm indoor maintenance.

4. Prune in time

Gardenia needs to be pruned twice a year, the first time in the month, at this time the end of the branch can be slightly pruned, the second pruning is generally in November and December when the plant is dormant, the internal diseased branches, weak branches, overlapping branches are all cut off.

<> gardenia is suitable for growing in acidic soil with a pH value of 5 to 6, if the pH of the soil is not suitable, it will not only affect the growth of gardenias, but also be troublesome to maintain in the future. Therefore, you can choose humus soil, peat soil and half of the garden soil for cultivation, and the easiest way is to buy gardenia soil directly.

Gardenias are particularly fertiliser-loving, and they need to be fertilized during planting, growing season, and budding period. When planting, you can add well-rotted cake fertilizer to the soil, and in the growing season, you can use cake fertilizer, ferrous sulfate to make fertilizer or full nutrient organic liquid fertilizer to water once a week, and you can use potassium dihydrogen phosphate aqueous solution to irrigate once or twice in the budding stage. Note that when the temperature reaches above 35 in summer or 15 in autumn, fertilization should be stopped.

Gardenias are suitable for growing in a moist and humid environment, and the growth period of gardenias is from April to September every year, so keep the soil moist every day, and spray the leaves at night. If the gardenia is very vigorous, then you can skip watering at night and wait until the sun rises during the day. Note:

If it is a alkaline water area in the north, then it can be left for one day before watering, and then watered with citric acid aqueous solution every three to five days, which can keep the leaves of gardenia green.

Gardenias are suitable for growing in sunny places, and if left in the shade for a long time, the flower branches of gardenias will become very thin and slender. In daily maintenance, except for the need for shade at noon in the month and hibernation in winter, the rest of the time can be maintained normally in the sun.

Gardenia planting and maintenance methods include water and fertilizer management, non-repotting, light requirements, pruning branches and leaves, water quantity control, etc.

1. Water and fertilizer management.

In the growth period of gardenia, excessive water and fertilizer will lead to the growth of branches and leaves, and the vigorous vegetative growth will inhibit the reproductive growth of flower organs, affecting the generation and differentiation of flower buds. Even if a bud grows, it is difficult to develop into a flower normally, and it is very easy to wither. Therefore, during the budding period, it is necessary to control the frequency of watering and apply thin fertilizer frequently.

2. Do not change the pot.

Gardenia bud is the most vigorous stage of physiological activity, which should not only meet the needs of physiological growth, but also meet the needs of reproductive growth. At this time, the root system needs to absorb a large amount of nutrients from the soil and transport them to the leaves and flowers. If repotting changes the environment of the root system, it will be difficult for the leaves and buds to adapt to the new environment and absorb nutrients.

3. Light requirements.

Gardenias prefer moist semi-shaded environments, but they should not be completely shaded and need adequate light. If there is not enough light in the growth environment, it will also cause a lack of nutrients, unable to carry out photosynthesis, unable to produce nutrients, and the phenomenon of yellowing of leaf color and falling flowers and buds will appear. Therefore, gardenias should be planted in a ventilated place with sunlight.

4. Prune branches and leaves.

When the buds are growing, if the branches and leaves are abundant and clever, they should be pruned in time. Vigorous branches compete not only for nutrients but also for light, blocking the light of the lower branches and leaves, making it impossible to photosynthesize. Long branches are susceptible to pests and diseases, and can even harm the entire plant, so it is necessary to prune and prune the leaves frequently, so that the nutrients are concentrated in the buds.

5. Water volume control.

When maintaining gardenias during the budding period, it is necessary to control the amount of watering, and wait for the soil to dry slightly, and then water properly to avoid the gardenia from rotting in water. And when fertilizing gardenias, do not sprinkle fertilizer on the leaf cores to avoid the condition of fertilizer damage and rot of gardenias, so that gardenias can grow healthily.
