How can it blossom?
1. Soil
Gardenia is an indicator plant of acidic soil, so the slightly acidic environment of soil is the key to determine the growth of gardenia. The culture soil is made of 70% of slightly acidic sandy red soil and 30% of rotten leaves. It is appropriate to control the soil pH value between 4.0 and 6.5.
Second, temperature
The optimum growth temperature of Gardenia jasminoides is 16 ℃-18 ℃. Too low temperature and direct sunlight are extremely disadvantageous to its growth, so it is appropriate to keep gardenia in sparse forest or shade shed with good ventilation, high air humidity and transparent light in summer. Winter in the sun, the temperature is not lower than 0 ℃ of the environment, let it dormant, the temperature is too high will affect the flowering in the coming year.
Third, moisture
Gardenia likes moist air, and should be watered appropriately during the growing period. Usually the pot soil can be watered once the soil turns white and thoroughly at one time. Hot and dry in summer, spray to the leaves 2-3 times a day to increase air humidity and help plant cool. However, after the flower budding, watering should not be too much, so as not to cause bud drop. It is better to water dry in winter to prevent the roots from rotting.
IV. Fertilizer
Gardenia is a fertilizer-loving plant. In order to meet the demand for fertilizer during its growing period and maintain the slightly acidic environment of the soil, ferrous sulfate can be mixed into the fertilizer solution in advance to ferment. After entering the peak growing season in April, you can top fertilize every half month (you'd better mix more water when fertilizing to prevent burning flowers). This can not only meet the fertilizer demand of Gardenia jasminoides, but also keep the soil environment in a relatively balanced slightly acidic environment, prevent the occurrence of chlorosis, and avoid the damage of sudden supplement of ferrous sulfate and local excessive acid to gardenia.
V. Reproduction
Although there are many ways to breed gardenia, the most simple and quick method is floating water insertion. First, find a foam board and punch holes up. Cut off the semi-ripe branches of Gardenia jasminoides that year, insert them into the holes of the foam board, then put the foam board into a bucket filled with water, and place the bucket in an environment that can not only shade the floating board, but also let the sun shine on the bucket, and control the water temperature between 18 ℃ and 25 ℃. Gardenia can grow roots of more than 3 centimeters in a week. This method cuttings gardenia flower, the survival rate is 100%.
