Matters needing attention in Gardenia Culture

1. Gardenia likes fat, but is afraid of thick fat

In general, apply 2 times of cake fertilizer containing phosphorus and potassium before budding, stop applying fertilizer after budding, if excessive fertilizer is applied, it is easy to burn roots and cause budding. During the growth period, decomposed cake fertilizer water or manure water is applied once every half month, and 1%~2% ferrous sulfate is added to prevent soil alkalization.

2. Gardenia likes semi-shade, afraid of direct sunlight, and requires shade of about 50%.

If exposed to the sun, the leaves yellow, white until falling off, so summer must be placed in shade or scattered light of the place maintenance. Make it early and late to see the light, lest the leaves yellow.

How to raise gardenia

First, acid soil culture

Gardenia needs to scatter light, so like acid soil, if the soil is alkaline, it will make Gardenia can not absorb iron very well, thus having a great impact on the formation of chlorophyll, further causing flowering branches to wither, or even die; so its soil must use loose, fertile acid soil, but also some substances with such effect can be added to it.

Second, put it in a cool place

Gardenia must not be placed in the sun exposure, otherwise it will cause the leaves to wither, but it is not said to be placed in the shade, because it has a certain demand for light, it is best to keep 60% of the daily light, in addition, into April, a month to fertilizer twice.

Third, air humidity

Gardenia likes humidity, so the air cannot be too dry. According to expert statistics, if the air humidity is lower than 70%, it will affect the normal opening of flowers, but if it is too wet, it will cause root rot and yellow leaves. Therefore, in addition to normal watering, water should be sprayed frequently nearby. Another problem to pay great attention to is that water cannot be poured too much, otherwise it will affect growth. When the soil is dry, knock the flowerpot with your hand. If there is an empty sound, you need watering. The bottom of the flowerpot starts to leak and stops. It is best to add some eggs, soy milk, etc. to the water poured, which is more conducive to growth.

Fourth, fertilization tips

Gardenia like fertilizer, but can not add too much fertilizer at one time, must be thin fertilizer more, must not be greedy trouble, otherwise it will cause thick branches, big leaves, thick green, it will lose its own appreciation effect.

Fifth, temperature requirements

Gardenia growth temperature can not be too low, because it is thermophilic, generally speaking, the temperature of the growth period in 18 to 22 degrees is better, winter 5 to 10 degrees, if less than minus 10 degrees will be frostbite, this north should pay special attention to.

Sixth, proper pruning

Gardenia is very easy to grow luxuriant foliage, and cause airtight and disorderly feeling, this will cause nutrition dispersion and ornamental deterioration, so it needs to be pruned, pruning had better choose to stay 3 main branches, and cut off the root tiller sprout new branches at any time, after the flower withers, the branches should be truncated in time, so that new branches will sprout under the shear. When the new branches grow out of three sections, they should be picked to avoid blind growth.

Gardenia cultivation precautions

1. The propagation methods of Gardenia jasminoides L. are cutting, layering and dividing.

2. Pay attention to the prevention and control of gardenia diseases and insect pests. Generally gardenia is prone to yellow horse disease. In addition, leaf spot disease and ulcer disease occur from time to time. We should pay more attention to it. Gardenia is also prone to a kind of Malpighia whitefly pest attack, if encountered, you can consult professionals for pest control.

3. Gardenia is very sensitive to moisture, so it should use a tile basin with good ventilation performance as the bottom of the pot, so that watering Gardenia will not cause ponding phenomenon, leading to yellow leaves falling off, and even leading to death of flowers and plants in serious cases.

4. As for the cutting time of Gardenia, April is the best in the first half of the year, and August to September is the best in the second half of the year. These two time periods are the best seasons for Gardenia reproduction.

5, before and after gardenia cuttings should not be fertilized, this time only need to grow naturally, even if it is natural fertilizer, urea, chemical fertilizer and so on.

Gardenia cultivation method is not complicated, on the contrary, it is a relatively easy to take care of plants, no matter where it is placed in the corner, it plays its own small value, especially in early summer when flowers bloom, floral refreshing.

How do gardenia grow? Notes on Gardenia Conservation

I. Soil

The flower likes to grow in acidic soil with more humus. It can be mixed with 4 parts of rotten leaf soil, 4 parts of vegetable garden soil, 1 part of soybean meal (decomposed) and 1 part of river sand, with good water permeability and permeability, and then 0.5% of black alum or sulfur.

II. Temperature

Gardenia jasminoides L. grows best at 20-25℃ and blooms at 26-28℃. After 4-5 years of cultivation, the plants can endure short-term low temperature of-3℃, and suffer from freezing injury below-5℃. The leaves blacken and fall off, and the young branches freeze to death. Winter indoor maintenance to maintain 6-10℃ is appropriate, the minimum shall not be lower than 0℃. If the room temperature is higher than 15℃, it should open the south-facing doors and windows, properly ventilate, reduce the temperature, otherwise it is easy to cause germination, and it will suffer from low temperature, which is extremely unfavorable for the growth and flowering of the next year.

III. Illumination

Gardenia likes sufficient light, especially in spring and autumn, more than 8 hours of sunshine per day, otherwise it is unfavorable for its growth and winter overwintering. Summer avoid strong sunlight at noon, otherwise it will make the leaves yellow, to be placed at the astigmatism maintenance, transmittance of 40-50% is appropriate. In winter, it is placed indoors in direct sunlight facing south.

IV. Fertilization

Gardenia is not a very fertile flower, but because it grows vigorously and is limited by pot nutrients, it needs reasonable fertilizer supplement during its growth period. Every 10 days or so apply decomposed human manure or cake fertilizer, in the first day before fertilization should stop watering, fertilization day at the same time watering 1 permeable. Fertilization stops in mid-September. Adult plants, in mid-June and mid-August, add sesame sauce residue once, 0.5-1 liang each time, crush and fully mix with topsoil.

VI. Tipping

In order to regulate and control the growth of Gardenia, make the plant shape beautiful and promote flowering, when the vigorous growth in spring will stop, the top of the new branch will be picked off, so as to promote the axillary buds at the base of the branch to be full and the formation of flower buds.
