Question
I got a piece of an arrowhead vine from a friend and cut it and put it in water but it hasn't sprouted any new roots yet-it's been a month. How is it propagated?

Answer
Hi Bernard,

There are several different plants that are commonly called "Arrowhead." I suggest that you either post a photo of your cutting here or email it to my address below so we can properly identify it.

I will make an educated guess that yours is a Syngonium. If so, the cutting must have at least one node that is kept under water at all times. A node is the slightly raised bump on a stem where the leaf stem attaches to the main stem. When in constant contact with water or damp soil, a node will gradually swell and produce roots. This usually takes at least a month and could take as much as three months to produce viable roots that are at least an inch long.

Possible causes for lack of root development include a non-viable cutting, allowing the node to become dry even for a short time, and very poor light. Otherwise, change the water once per week and be patient.

I have written a detailed article on plant propagation that I will email for free to you (or anyone else) who emails a request to me at [email protected]. I have also written an indoor plant care book in a PDF format that I can sell you if you contact me at my email address.

Please let me know if any of this is unclear or if you have any additional questions.
