Hydrangeas can be challenging to propagate if you don't have the right elements in place: plenty of bright light, lots of warmth, humidity, and consistent moisture. But, what if I told you a potato can help provide ideal conditions to root hydrangea cuttings?
This hack consists of propagating hydrangeas by literally sticking cuttings in a potato. It might sound bizarre (and it definitely looks it), but it actually works. Just like growing rose cuttings in potatoes, this vegetable can act as a supportive growing medium, full of plant nutrients and moisture to encourage rooting. It's a clever trick to stop cuttings drying out in particular, the number one reason hydrangea cuttings fail to root.
