20 years of gardenia keep full bloom and learn how to do it.

Most flower lovers grow flowers and hope that the flowers at home can accompany them for 5, 10, 20 years. Even for the rest of my life. Gardenia leaves are evergreen all the year round, fragrant and elegant flowers, green leaves and white flowers, particularly beautiful and lovely, very suitable for planting in front and behind the house, and as the tree grows older, it grows thicker and thicker, and blooms more and more explosively. But how can we raise gardenia for a lifetime? Take a quick look!

1. Suitable soil

Gardenia likes to grow in acidic soil, and the suitable pH value is 5 to 6. Properly put ferrous sulfate in the watering of flowers, the proportion of ferrous sulfate is 1Rd 500 to dilute watering, improve the acidity of the soil and supplement the acid substances of plant growth, the leaves will not appear iron deficiency yellow. If the soil acidity is not suitable, it will get twice the result with half the effort in the future management.

2. Scientific watering

Gardenia likes moist soil and high air humidity. Keep the basin soil moist during the growth period from April to September. The surface of the basin soil is watered when it is dry, and a spray can be used to pour water on the leaf surface at night. If it is dry and wilted, it will be bad for growth. If the growth is too prosperous and the internodes are longer, they will not be watered in the evening and will be watered again when the sun comes out in the morning. At the same time, we should also pay attention to spraying some water on the leaves of gardenia, which can improve the humidity of the air. At the same time, we should also pay attention to not watering too much in winter to prevent the occurrence of rotting roots.

3. Sufficient light

Gardenia likes light and can grow in semi-shade for a long time, but the flower branches are longer and the flowers are less. In addition to the strong light from July to August noon need shade and winter dormancy period, generally need to be maintained in the sun in order to blossom and flourish. In the spring and autumn period, pay more attention to increase the light time, and to the summer and winter season, it is recommended to put in the same light indoor culture, to avoid the growth period, the temperature is too high or too low.

4. Rational fertilization

Gardenia likes to be fat. 3% rotten cake fertilizer can be added to the culture soil as base fertilizer. In the growing season, the alum fertilizer made by cake fertilizer and ferrous sulfate retting is watered once a week, or 0.1% humic acid total nutrient organic liquid fertilizer can be used. Watering 0.1% potassium dihydrogen phosphate aqueous solution once to twice during flower bud and flowering period can promote flowering, make flowers hypertrophy and rich in fragrance. Fertilizer is stopped when the temperature is above 35 ℃ in hot summer and below 15 ℃ in autumn.
