Prosopis ‘Rio Salado’

Thornless mesquite

OVERVIEW:

Prosopis “Rio Salado’ is a V&P trademarked thornless mesquite tree growing up to 30 feet tall and 40 feet wide. In comparison to Prosopis chilensis, Rio Salado has much broader leaves and grows at a faster rate. It features brown fissured bark and compound 4-7cm long green leaves, each with several pairs of pinnate leaflets. Blooming period is in spring and sometimes sporadically again in late summer. Flowers are yellowish white, about 5 mm long, abundant and occur in spike-like racemes. Flat and slender pods proceed blooms and grow in drooping clusters. Root system is shallow but extensive and spreading. This tree thrives in lean, fast-draining soils. Fertilize lightly when new growth begins in spring. Water deeply and regularly during the first growing season until established. Once established, water only occasionally, as needed; being aware that over-watering causes structurally weak wood.
