Erigeron sumatrensis (syn. Conyza sumatrensis) is an annual herb probably native to South America, but widely naturalised in tropical and subtropical regions, and regarded as an invasive weed in many places. In the British Isles it is known as Guernsey fleabane. Other common names include fleabane, tall fleabane, broad-leaved fleabane, white horseweed, and Sumatran fleabane.
Guernsey fleabane has strong resistance to disease and generally does not suffer from many illnesses. Still, it can be affected by pests and diseases present in its environment. Such infections tend to be mild. Regarding upkeep, this plant calls for medium maintenance. It should be pruned on a regular basis to preserve a neat appearance and encourage healthy growth. Applying fertilizer can also aid in boosting flowering. Guernsey fleabane is appropriate for anyone with outdoor space, like a garden or patio, and does not demand extensive gardening experience. It may need more attention when cultivated indoors.
How to keep Conyza Albida.
Light
Guernsey fleabane grows best in locations that get plenty of sun year-round. Because it comes from habitats with abundant sunlight, insufficient light can restrict its growth. Although it is generally tolerant of a lot of sun, too much exposure can still cause damage.
Temperature
Guernsey fleabane originates from habitats characterized by mild to warm temperatures and prefers conditions between 68 and 95 °F (20 to 35 ℃). Keeping temperatures within this range year-round will preserve its vitality.
Fertilizer
Guernsey fleabane does well with frequent, light applications of fertilizer to encourage healthy leaf growth. You should feed Guernsey fleabane about once a month during the summer. Nitrogen is important for foliage, and adding nitrogen-rich fertilizer helps Guernsey fleabane prosper.
