Heliamphora pollination is tricky, and best done naturally by the vibrating wings of bees and flying pollinators. This isn’t always an option for indoor growers, so a simple technique using a tuning fork can mimic the vibrations that cause pollen release. For this method, acquire a small tuning fork, grab a smooth piece of paper, and a small paintbrush.
Place the piece of paper below the flower and touch the pollen sacs with a vibrating tuning fork. If pollen sacs are mature, a small amount of yellow dust-like pollen will fall to the piece of paper. Collect the pollen with a paintbrush and paint it onto the receptive stigma of another recently-opened flower.
You can also easily hybridize Heliamphora by cross-pollinating different species. Simply collect pollen from one species and apply to the stigma of another. Some common crosses include H. nutans x heterodoxa, H. heterodoxa x minor, and H. nutans x minor. Hybrids will have a mix of characteristics from each parent and extra vigor.
