How to raise gardenias at home, how to raise gardenias at home

Cultivation of gardenias.

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.

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.

4. Fertilizer: Gardenia is a fertilizer-loving plant, in order to meet its demand for fertilizer during the growth period, and to maintain the slightly acidic environment of the soil, ferrous sulfate can be mixed into the fertilizer solution in advance for fermentation. 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 demand of gardenia, but also keep the soil environment in a relatively balanced slightly acidic environment, prevent the occurrence of yellowing, and at the same time avoid the sudden supplementation of ferrous sulfate, local acid damage to gardenia.

Home farming gardenias requires a loose, fertile and well-drained slightly acidic soil substrate. Gardenia likes fertilizer, apply a thin nitrogen fertilizer once every ten days during the growth period, and apply a suitable phosphorus and potassium fertilizer during the flowering period. Gardenias love water, but avoid stagnant water.

Gardenias can be propagated by cuttings every autumn.

Gardenia likes fertilizer growth period and flowering before must ensure that the fertilizer is sufficient, in the growth period can be applied every ten days to apply nitrogen fertilizer, the concentration can not be too high, it is best to dilute before use, in the flower bud formation period and flowering period to apply appropriate phosphorus and potassium fertilizer, can promote the formation of flower buds and help plants better flowering.

Gardenia is generally used to propagate by cuttings, choose about 15cm long strong branches every autumn, retain two or three leaves at the top, insert the branches into the moist soil, and maintain a suitable temperature, after more than a month, the gardenia will take root, and then transplant it to the pot after full survival and careful maintenance.

The home maintenance method of gardenia is potting soil selection, scientific watering, reasonable fertilization, more sunlight, and good dormancy in winter.

1. Potting soil selection.

Gardenias are indicator flowers that prefer acidic soils and have a suitable pH of 5 to 6. Therefore, the slightly acidic environment of the soil is the key to determining the growth of gardenias. If the soil acidity is not suitable, it will be half the effort in the management of Zen change in the future.

The culture soil should be mixed with 7 parts of slightly acidic sandy loam laterite and 3 parts of humus.

2. Scientific watering.

Gardenias prefer moist soil and high air humidity. Keep the potting soil moist during the growing season from April to September. During the growing season, increase watering appropriately.

Usually the potting soil can be watered when it is white, and it can be watered thoroughly at one time. In summer, the foliar spray should be sprayed 2 to 3 times a day to increase the humidity of the air and help cool the plants. 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.

3. Reasonable fertilization.

Gardenia is a fertilizer-loving plant, and 3% rotting cake fertilizer can be added to the culture soil as base fertilizer. In the growing season, the alum fertilizer water prepared by cake fertilizer and ferrous sulfate is watered once a week, and humic acid full nutrient organic liquid fertilizer can also be used. Watering 1 to 2 times of potassium dihydrogen phosphate aqueous solution at the budding stage can make the flowers hypertrophied and fragrant.

4. Get more sun.

Gardenias love light and can grow in semi-shade for a long time, but the flower branches are longer and the flowers are fewer. Except for the strong light from July to noon in August and the dormant period in winter, they generally need to be maintained in the sun in order to flourish.

5. Good dormancy in winter.

Gardenias can overwinter in the open field in the Qinling Mountains of China, but the root system of potted gardenias will be damaged after severe winter, and the recovery will be slow in spring. In the heated indoor wintering, although it is not damaged by frost, it is not exposed to sunlight, and the growth is thin, and most of the young buds of the shape bridge are falling off in autumn, and the flowers bloom late the next year.

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.
