How to grow large-leafed cassia in the north

1. Soil

The soil in the north is usually alkaline or neutral, but large-leaf gardenia prefers acidic soil, so be careful when using soil. You can mix leaf mold, garden soil, and sandy soil together, and then add a small amount of sulfur powder. This can basically meet the growth needs and prevent yellowing leaves.

2. Watering

When watering, it is best to use fermented rice water or rain water. Water frequently during the growing period to keep it moist. The climate in the north is relatively dry, so you need to spray more water to increase the humidity. In addition, alum fertilizer should be applied once every half a month or so, which can not only supplement iron elements but also prevent the soil from becoming alkaline.

3. Lighting

It likes light, but is afraid of strong light. If exposed to direct strong sunlight, the leaves will turn white and yellow, so they should be placed in diffuse light in the summer and exposed to appropriate amounts of light in the morning and evening to prevent yellowing of the leaves.

4. Temperature

It is not cold-resistant, so it needs to be moved indoors for maintenance in late autumn and placed in a well-lit area. The indoor temperature should be kept at around 10 to 12 degrees. You should also be careful in early spring and not move the plant out too early. It is enough to move it out in late April. The temperature will be unstable if moved out too early and it will be easy to get frostbite.
