Sunlight
All plants require light for photosynthesis, the process within a plant that converts light, oxygen, and water into carbohydrates (energy). Plants require this energy to grow, bloom and produce seeds. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die. They need 12-14 hours of indirect sunlight.
Soil
The ideal blend of soil for plant growth is called loam. Often referred to as topsoil or black dirt by landscape companies, loam is a mixture of sand, clay, and silt.
Temperature
These plants are hardy in the areas with the lowest winter temperatures between 10°F and 20°F or -12.2°C and -6.7°C. In cooler regions, they can be treated as annuals. When planting, make sure the ground temperature reached 60°F.

Container
When choosing a pot, choose a pot that is 2.5-5 cm (1-2”) larger than the current size. Ceramic pots are porous which means your plants are less likely to experience root rot from overwatering. It also means you'll have to water more often. Plastic pots are lighter, less likely to break, and easier to clean.
