Light Requirements
Tillaea erecta Hook. & Arn. ssp. eremica (Jepson) Wiggins plants require full sunlight to grow and thrive. They can tolerate a few hours of partial shade a day, but too much shade can lead to stunted growth or even death. Thus, it is best to plant them in areas with an ample amount of sunlight.
Temperature Requirements
Tillaea erecta Hook. & Arn. ssp. eremica (Jepson) Wiggins plants grow in warm and dry conditions. They thrive in hot climates and can withstand temperatures of up to 90 degrees Fahrenheit. However, they cannot survive in below-freezing temperatures and require protection from frost and freezing conditions. Therefore, it is best to plant them in areas with a warm climate.
Soil Requirements
Tillaea erecta Hook. & Arn. ssp. eremica (Jepson) Wiggins plants require well-draining soil with low to moderate fertility. They prefer rocky, sandy, or gravelly soils that are low in organic matter. The soil's pH level should be neutral to slightly acidic, ranging from 6.0 to 7.5. The plants can tolerate drought conditions, but regular watering during the growing season can boost their growth. Therefore, it is best to plant them in well-draining soils with low fertility and neutral to slightly acidic pH levels.
Cultivation Methods
