Asters

Asters are high-value, star-shaped filler flowers grown in Kenya for both local and export markets. They produce long, wiry stems and deliver strong vase life, which makes them suitable for bouquet work and commercial floristry. In addition, their clustered blooms create volume and soft texture in floral arrangements. Farmers mainly grow them in open-field and semi-protected systems in areas such as Kiambu, Naivasha, and Juja, where moderate temperatures support steady flowering. As a result, Kenyan asters supply both domestic florists and international buyers in Europe and other export destinations.

Varieties

Kenyan production includes key commercial varieties such as Aster Dark Milka (deep purple) and Aster Teeny Tiny Pink. Moreover, growers also cultivate mixed Asteraceae types in white, lilac, pink, and soft lavender shades. These varieties differ in stem strength, bloom density, and colour intensity. Therefore, farmers select specific types based on bouquet demand, export requirements, and market trends in ornamental design.

Climate & Soil

Asters perform best in full sun, although they tolerate light shade when temperatures rise. They thrive at moderate elevations where daytime warmth and cool nights support balanced growth. In addition, they prefer well-drained, fertile soils with a light texture that supports root development. However, heavy or waterlogged soils reduce stem quality and increase disease pressure, so farmers prioritise good drainage and field aeration.

Propagation & Planting

Farmers propagate asters mainly from seeds, which they sow between February and April under Kenyan conditions. They plant seeds shallowly at about 0.5 cm depth to support uniform germination. Furthermore, they transplant seedlings into prepared beds once they develop strong root systems. In addition, growers maintain proper spacing to improve airflow and reduce pest buildup during early growth stages.

Field Management & Harvesting

Growers manage asters through regular weeding, balanced fertilization, and close pest monitoring. Moreover, they actively control aphids and spider mites, which commonly affect flower quality. Farmers harvest stems when blooms fully open and reach optimal colour intensity. After harvesting, they immediately grade, hydrate, and cool the stems to maintain firmness and extend vase life. Consequently, asters retain their structure and colour, making them reliable for both local bouquet markets and export supply chains.
