Plants utilize carbon dioxide to create oxygen and breathing, an inverse handle in which plants use oxygen to produce carbon dioxide. More so, container Mexican heather plants would dry faster, so water them often. The effect of temperature is enhanced under high vapor pressure deficits because pollen viability (prior to silk reception) is a function of pollen moisture content which is strongly dependent on vapor pressure deficit (Fonseca and Westgate, 2005). Maintain a strategic distance from watering shallowly as this empowers shallow roots. Before you give them up, you may also find it comfortable to grow Mexican heather in the greenhouse.
