This is more for experimental purposes than being critical to my growing but I have never been very successful in rooting cuttings by just placing them in a glass of water. I have placed cuttings in water and had them live for a long time (even several months months) but have rarely gotten roots. I've tried tap water, bottled spring water, distilled water and rain water and it doesn't make a difference. I've tried in a sunny windowsill, a shady window, and under a grow light and still not much. I've even tried bubbling the water with an airstone. The only time I've been totally successful is last fall when a large budded branch broke off a plant in a windstorm. I threw it into a small empty nutrient bottle filled with tap water to keep it alive so I could try to harvest the buds on them when they were ready. When I went to harvest the buds, I was surprised that the stem was full of roots! I am now growing that branch outside and it is a nice plant just starting to flower.
I normally tend to dangle the stems in a glass of water but with this broken branch, it was in the nute bottle with the stem touching the bottom. Was that the difference? That the stem needs to be touching the bottom of the vessel to start rooting?
BTW, I have never had a problem propagating other plants with just our tap water like basil, mint, oregano, pothos, snake plants and many, many others.
