This plant develops best with a mild climate, so it can not stand the intense cold and even the summer temperatures too high, so it is often grown as an indoor plant.
The ideal temperatures for the Bouvardia are fifteen to twenty-four degrees from February to September, in the remaining months the temperature should be kept between thirteen and fifteen degrees.
In summer, watering should be regular or abundant if it’s hot, but avoid exceeding, causing the presence of water stagnation that would quickly compromise the health. In winter, only moist soil should be kept, thus reducing water supply interventions. After pruning, watering should be more abundant.
