How to care for gardenia in spring? A full breakdown of spring care methods
1. Soil
Choosing a suitable potting soil is very important. It is a plant that prefers acidity, with a suitable pH between 5 and 6. It is very sensitive to alkaline soil, so it must never be planted in alkaline loam. For the potting soil, you can use a sandy loam red soil mixed with peat soil, leaf mold, garden soil, etc.; do not use cinder soil and the like that contains no humus.
2. Temperature
The temperature suitable for its growth is 16 to 18°C, which generally fits the average spring temperature quite well. However, if it is too low or exposed to direct sunlight, it will cause some harm to its growth. So in early spring, if the temperature is too low, we need to make sure to take warming measures. Normally, keep it in a place with good ventilation and plenty of sunlight.
3. Water
For it, water control must be strict. It prefers moisture, but excessive dampness will cause root rot, so watering must be done properly. The watering frequency mainly depends on how dry or moist the loam is; water as soon as the potting soil dries out. In the evening, you can mist the leaves with a spray bottle to increase humidity.
4. Fertilizer
It is a plant that likes fertilizer, but considering that it must grow in acidic potting soil, each time you fertilize, add a small amount of ferrous sulfate to the fertilizer, let it ferment for a while, and then apply the fertilizer. In spring, during the peak growth period, you can fertilize once every half month. It is best to dilute the fertilizer with some water to avoid burning the roots due to too high a concentration.
