We have very little information on this species and do not know if it will succeed outdoors in Britain, though it should be possible to grow it as a spring-sown annual. The following notes are based on the general needs of the genus. Succeeds in any moderately fertile moisture-retentive soil in full sun[200].

This plant can be weedy or invasive. Some indication in Hawaii, USA. B. pilosa is native to tropical America but is now a pantropical weed (Wagner et al., 1999). Latin America and eastern Africa have the worst infestations of the weed (Mitich, 1994). It is regarded as a principal weed of sugarcane, maize, coffee, tea, cotton, potatoes, vegetables, bananas, beans and citrus in various Latin American and African countries (Holm et al., 1977) and a serious weed in many other situations. In upland rice in South and South-East Asia, it is common in Thailand and present in Indonesia, Laos, Myanmar, Philippines and Vietnam [1d].
