For gardenia, the soil environment is very important because it has a preference. It likes a slightly acidic growth environment, so it is necessary to choose the soil before planting flowers. The pH value of flower soil should be controlled in the range of 4.0 ~ 6.5.

2. Temperature

It is also necessary to control the temperature, and its optimum growth temperature is between 16 ~ 18. Because temperature is the key, it should be well preserved. If there is no suitable temperature, the growth of gardenia will be hindered. In addition, it is necessary to pay attention to ventilation conditions and maintain good ventilation to make it grow well.

Breeding method:

Gardenia branches take root easily. Warm land in the south is often cut in March-65438+10, and warm land in the north is often cut in May-June. Cutting strong and mature branches into sand beds can easily take root and survive as long as they are kept moist.

Water cuttings are far superior to soil cuttings, and the survival rate is close to 65,438+0,000%. Cuttings were cut from April to July, only the top two leaves and terminal buds were kept, and they were inserted in a container filled with clear water, and the water was often changed to avoid the incision from rotting. After 3 weeks, the cuttings began to take root.

It is better to transplant seedlings or potted plants in spring, and soil balls are needed in rainy season. Keep the soil moist during the growing period, and water it more during flowering and midsummer. Apply fertilizer 1 time every month, and apply phosphorus and potassium fertilizer 1 time before flowering. Prune and reshape in early spring of the following year, and cut off dead branches and long branches in time.
