Summary The problem of weeds in ornamental bulb plantings (tulip, daffodil, iris, gladiolus, and lily) and weed management is reviewed in this paper. Ecological niche for weeds, floristic structure of weed communities and weed population dynamics in bulb plantings depends on different agrobiological factors. Ornamental bulbs are susceptible to weed infestation, particularly during the early stages of growth, but it is better to keep the crop weed free throughout lifecycle, because weeds cause yield reduction, may alter quality and size of bulbs and flowers quality. These plants do not shade out weeds that emerge in the rows and are fairly shallow rooted and care must be taken not to prune these roots with inter‐row mechanical cultivation. Therefore, in integrated weed control strategies herbicides ought to be included. Ornamental bulbs belong to minor crops. In spite of it in most of countries herbicides are registered for use in ornamental bulbs to ensure necessary protection. Among others: chlorpropham, pendimethalin, linuron, metamitron, clopyralid, glyphosat and some graminicides are authorized and recommended. The possibilities of weed control on Poland in comparison to other countries is discussed.
