If the indoor light is not strong, it should be moved into the sun for appropriate exposure every few weeks; only then will its leaves be more vividly green.

3. Temperature

Norfolk Island pine likes a warm environment, and the most suitable growing temperature is 10-25°C; at this temperature, it can grow all year round. However, Norfolk Island pine dislikes high temperatures and is not cold-tolerant either; its growing temperature cannot exceed 32°C in summer and cannot be lower than 5°C in winter.

4. Watering
