Little is known about competitive or facilitative interactions between pollinator dependent crops with respect to pollinators and pollinator services; however, we expect that these interactions are ubiquitous in agricultural landscapes. They only require that crops have overlap in their pollinator community though they may bloom in different seasons21 or even in different years20. The likelihood of the interaction resulting in either facilitation or competition depends not only on the degree of overlap in the pollinator community15 but also on the temporal overlap in bloom between crops132124. Indeed, the two studies available on the effects of mass flowering crops on wild plants have found that mass flowering crops can either reduce25 or enhance pollination13 in co-blooming plants in nearby natural habitats.
