How to manage and maintain potted gardenias in the north Details 0 3

The process of forming cypress bonsai is only over and over again, repeatedly tied with aluminum wire!

1. Soil selection.

Because the climate and environment of the north and south are different, the soil used for breeding plants is also different, and the soil in the north is often alkaline or alkaline, so gardenias often do not grow well in the northern potting soil, and after a long time, they will even weaken and die, so it is best to simply prepare the culture soil suitable for planting gardenias can be used in pots according to the ratio of 1:1 between sandy loam soil and peaty soil.

2. Lighting requirements.

Its growth environment is generally very bright, especially in spring and autumn, and it must be ensured that it can receive at least 8 hours of sunshine every day, otherwise it will be extremely unfavorable for its future wintering and growth. However, in the hot summer, to avoid strong light exposure, it is best to place it in a place of astigmatism for maintenance, and then transfer the mill to a place in direct sunlight after winter.

3. Watering management.

The winter in the north is cold, and most of the gardenias stop growing or grow slowly (except in greenhouses), which consumes less water and should be watered less. If the temperature is not high, according to the dryness and wetness of the soil in the pot, water 1 or 2 times a week.

4. Proper fertilization.

Gardenia fertilization adheres to the principle of "thin fertilizer and diligent application", and fertilizer is generally applied once a week. During the period from budding to flowering, the number of fertilization can be increased appropriately to promote the development of flower buds. However, in winter, gardenias are semi-dormant, and fertilization is harmful.

In the family flower raising, it is strictly forbidden to apply raw fertilizer that has not been fermented and rotted, which can not play the role of fertilizer, and is easy to burn the roots and grow maggots, and at the same time the smell spreads, and it is not hygienic.

5. Precautions: The climate and environment in the north is relatively cold, especially in winter, the temperature is often lower than minus dozens of degrees, because if you want to breed gardenias in this harsh environment, you must first be prepared to raise the indoor temperature. Therefore, it is best to breed gardenias in a place with a higher temperature, such as a bedroom and living room, but to ensure that the indoor temperature is not too low, the lowest can not be lower than five degrees Celsius, otherwise the plant will have frostbite, and when breeding gardenias in winter, it is best not to fertilize, otherwise it will lead to rotten roots of the plant.

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.

Gardenia breeding methods and precautions, teach you a trick, year after year!

1. 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. Hope to adopt.
