Resource allocation patterns and trade‐off between sexual and clonal reproduction in clonal plants have been extensively studied, but little is known about effects of organ removal on the trade‐offs in clonal plants. To examine the effects, we conducted an experiment with the stoloniferous herb Duchesnea indica in which we removed plant organs like roots, flowers, or fruits. Removing roots significantly increased number of ramets and biomass allocation to stolons, but decreased number of fruits. Removing flowers or fruits greatly increased number of ramets and biomass allocation to stolons and roots, but decreased spacer length, number of fruits, and fruits set. Onset and median date of flowering phenology of D. indica shifted after flowers, fruits, or roots were removed. These results may indicate that removing organs can affect trade‐off between sexual and clonal reproduction of D. indica.
