Q.How to propagate mandevilla cuttings in water?
I’ve read people don’t have any luck propagating mandevilla cuttings in plain water but wonder if there’s a trick to it, like adding something to the water, or other tips?

Yes, there is a way to do this. This can be a bit more tricky than cloning in soil, however, with the right tools, you can do it easily. the best way to achieve success with this method is to have the water always moving, and always oxygenated. The easiest way to do this is to put an airstone attached to an air pump into the water at the bottom of the container. This can be a simple aquarium pump and does not have to be big, The next step requires some sort of hormone, or rooting solution. Personally I have had great results with both crushed up aspirin, and honey. It will not hurt to use both at the same time. This will bring your success rate way up! It is necessary to change the water, and solution about every 3 days or so. If you need more assistance with this subject, please do not hesitate to post more questions here.
