In summer, agapanthus requires bright lighting, so it is best to place this plant near a south-facing window. During the summer period, it can also be taken out onto a balcony. In winter, a cool, well-lit room with an air temperature of 10-12 °C (50-54 °F) is preferable. In spring, summer, and autumn, abundant watering is required. In winter, watering should be reduced, while ensuring that the soil does not dry out completely. Agapanthus calmly tolerates dry air, so additional spraying is not necessary.
During the growing season, feeding with organic and mineral fertilizers is desirable. Fertilizer applications should alternate between the two. Vigorous growth and abundant flowering in agapanthus are provided by a nutritious potting mix of sand, sod soil, humus, and leaf mold. It is best to use wide pots with good drainage for planting. The plant dislikes frequent repotting, so young specimens are repotted annually, and mature ones once every several years.
Tolerating dry air well and not requiring misting, the flower can nevertheless be affected by red spider mites, which reproduce actively in dry air. It can also suffer from excessive watering: to prevent issues, good drainage should be provided in the pot or container. Overwatering the soil can cause yellowing of the leaves, so watering must be properly regulated. If the plant lacks light, its peduncles will elongate excessively during flowering. In that case, plant supports must be used.
