You can determine if pollination has occurred once seeds begin to develop, which typically takes a few weeks. Pollination is not immediately apparent. If you are cautious about controlling the spread of pollen, any resulting seeds are usually limited in number and tend to form close to where the male flower was located. This localized seed development aligns with how pollen tends to settle and fertilize nearby flowers when the process is accidental or minimally distributed.
Good luck! 👍😎.
