Therefore, a location with bright and direct sunlight exposure would be ideal for the plant's optimal growth.
Temperature Requirements
The plant Strychnos spinosa Lam. var. lokua (A.Rich.) E.A.Bruce grows in warm climates with an average temperature range of 20°C to 30°C (68°F to 86°F). It cannot tolerate extreme temperatures and frost. Therefore, it is essential to grow the plant in a location with a warm and stable temperature range to promote healthy growth.
Soil Requirements
The plant Strychnos spinosa Lam. var. lokua (A.Rich.) E.A.Bruce requires well-draining soil with a pH range between neutral to slightly acidic conditions (pH 6.0 to 7.5). The soil should be rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium to sustain healthy plant growth. It can tolerate a wide range of soil textures, including sandy and clay soils. However, the soil must be free from any waterlogging or standing water, which can cause root rot and other diseases in the plant.
Cultivation Methods
Strychnos spinosa Lam. var. lokua (A.Rich.) E.A.Bruce, commonly known as the Poison Arrow Tree, is a tropical plant that can grow up to 10 meters tall. It requires warm temperatures and high humidity to thrive, making it suitable for cultivation in tropical or subtropical environments. This plant prefers well-draining soil that is rich in organic matter and adequate sunlight for at least 6 hours a day.
Watering Needs
The Poison Arrow Tree requires regular watering to maintain healthy growth. It should be watered deeply but infrequently, allowing the soil to dry out between watering sessions. Overwatering can cause root rot and other plant diseases. Additionally, excessive moisture can attract pests and insects that can harm the plant.
Fertilization
