This study was conducted at the Ornamental Plants Nursery of the Department of Horticulture, Faculty of agriculture, University of Khartoum, Shambat, Sudan during 2015. The objective was to study the effect of mixing silty soil/SS (Revarian sediments) and field soil with compost and leaf mould (organic amendments) at different ratios on growth and flowering of bougainvillea (Bougainvillea sp.). Bougainvillea transplants were potted into polyethylene bags (40 cm diameter and 50 cm height) containing the following media as treatments: silty soil (SS) 100%, SS 75% + compost 25%, SS 50% + compost 50%, SS 75% + leaf mould 25%, SS 50% + leaf mould 50%, field soil 100%, field soil 75% + compost 25%, field soil 50% + compost 50%, field soil 75%+leaf mould 25%, field soil 50% + leaf mould 50%. Treatments were arranged in a randomized complete block design and replicated thrice. Three plants represented an experimental unit.  Data were collected on plant height, number of branches per plant, number of leaves per plant, stem diameter, plant fresh and dry weights, and number of inflorescences per plant. Bougainvillea plant response towards organic amendments was higher in SS than in field soil. The treatment SS 75% + compost 25% resulted in highest plant height, stem diameter, plant fresh weight and plant dry weight. The highest number of branches/plant was recorded by the treatments SS 75% + leaf mould 25% and field soil 75% + leaf mould 25%. The treatment SS 50% + compost 50% resulted in highest number of leaves/plant and number of inflorescences/plant. The lowest values of all parameters was recorded by the treatment field soil 50% + leaf mould 50%. It can be concluded that 25% compost or leaf mould added to 75%  field soil is a reasonable potting medium for bougainvillea.
