It can tolerate temperatures as low as 10 °C (50 °F) and as high as 30 °C (86 °F). However, temperatures below 10 °C (50 °F) or above 35 °C (95 °F) can be fatal for the plant.
Soil Requirements
The soil requirements for Diascia bergiana Eckl. ex Hiern, non Link & Otto can be described as well-draining, acidic soil with moderate fertility. A pH range between 5.5 to 6.5 is ideal for this plant. The soil should be moist but not waterlogged as it can lead to root rot. Adding organic matter like compost or peat moss to the soil can improve its fertility and water-retaining capacity.
Cultivation Method:
The Diascia bergiana plant grows well in well-draining soil, preferably sandy loam soil. It requires a moderate amount of sunlight, so it is best to plant it in a partially shaded area.
If you are growing it indoors, set it in a south-facing window where it can obtain plenty of indirect sunlight. The plant may thrive in temperatures ranging from 18 to 22°C, and it requires well-draining soil to thrive. The plant prefers a pH range of 6.5 to 7.0 in both the soil and water.
Watering Needs:
The Diascia bergiana plant prefers moist soil. However, overwatering should be avoided at all costs since it can lead to root rot. Watering once every week and once every four days in hot months is ideal for the plant. Always soak the soil entirely, and allow any extra water to drain out of the pot's bottom.
Fertilization:
It is ideal for giving a plant-based fertilizer to the Diascia bergiana plant every two weeks throughout the bloom season, which is usually from spring through fall. Before giving any fertilizer, make sure to water the plant thoroughly and avoid fertilizing the leaves since it can lead to damaging the leaves.
Pruning:
To promote healthy growth, deadhead frequently by trimming the dead flowers along with some of the stem. When cutting back the plant, keep the plant's form in mind, and try to cut back at a node if possible. Pruning will assist plants in producing a more extensive bushy appearance by encouraging new growth to come forth at the node where the leaves meet the stem.
