Gardenia likes humid environment. Water at noon in winter. The water is best exposed to the sun. The water temperature is suitable. In spring and summer, water in the morning, and then bask in the sun. It's hot in summer, so water less in the morning and water permeable after 2:00 in the afternoon. 4~9 month growth period, keep basin soil moist, watering see dry to see wet, evening spray can leaf wet, in order to maintain humidity. If the plants grow too fast, do not water them at night. Water them when the sun comes out in the morning.
Gardenia is suitable for pouring acid water, standing water for more than 24 hours or after exposure to the sun. Rain water can be collected in the north. Or pour a little citric acid solution to enhance the acidity, so as to keep the leaves green. In addition to normal watering, the leaves and the surrounding ground should be sprayed with clean water frequently, and the air humidity should be increased appropriately. In summer, it is better to irrigate with soft water, because there are more calcium and magnesium salts in hard water, which is very harmful to its growth. If it is light, its branches and leaves turn yellow, and if it is heavy, it will soon die.
Potted gardenias should be watered thoroughly. Only when they are 3-5cm dry can they be watered. If they are watered too much, it is easy to cause root rot.
In spring in the north, due to the windy, windy, dry air and scarce rainfall, it is usually watered once every three days, and around the potted flowers, they should be watered in the morning and evening every day to improve the air humidity. In summer, water evaporates rapidly in hot weather, so it needs to be watered every day. When the temperature is high, spray water to the leaves of plants with a watering can. It can only be watered once every two days in autumn. In winter, the temperature is low and the water evaporation is very slow. Therefore, the watering should be reduced to ensure once a month. The watering is permeable and easy to rot if it is too frequent. In addition to normal watering, the leaves and the surrounding ground should be sprayed with clean water frequently, and the air humidity should be increased appropriately. The watering should be stopped one day before fertilization, and one time of water permeability should be poured at the same time on the day of fertilization.
