Temperature Range
This plant thrives in warm temperatures ranging from 20 to 25°C (68 to 77°F). It can tolerate temperatures as low as 5°C (40°F) but anything below that may result in frost damage or death of the plant.
Soil Requirements
Watsonia stokoei L.Bolus requires well-draining, fertile soil that is rich in organic matter. It can grow in a range of soil types, including loamy, sandy, and clay soils. The ideal soil pH level for this plant ranges from 6.0 to 7.0. It is important to ensure that the soil remains moist, but not waterlogged, during the growing season.
Cultivation Methods
Watsonia stokoei L.Bolus thrives well in well-drained soils with a pH range of 6.0 to 7.0. Planting should be done in early spring. The plant should be placed in an area with partial to full sunlight exposure. Spacing should be 15 to 20cm between the plants. In areas with strong winds, it is recommended to use stakes to support the stems.
Watering Needs
Watsonia stokoei L.Bolus requires moderate watering. During the growing period, mulching should be done to maintain soil moisture and reduce weed growth. The plant should be watered deeply twice a week during the growing season and once a week during the dormant season. It is essential to avoid waterlogging the soil because this may lead to root rot.
Fertilization
Watsonia stokoei L.Bolus is a heavy feeder. Adding well-decomposed compost during planting provides the necessary nutrients. Additional application of balanced fertilizer should be done during the growing season and not during the dormant season. Over-fertilization should be avoided because it may cause the plant to produce soft and weak stems.
Pruning
Watsonia stokoei L.Bolus requires minimal pruning. Deadheading helps to prolong the blooming period and enhance the appearance of the plant. After flowering, the spent flowers should be cut back to the base of the stem. Pruning should be done in the dormant season when the leaves have died back. The pruning shears should be disinfected to avoid spreading diseases.
