Should I be fertilizing my hydrangeas now? I seem to remember being told (before I had any) they needed muric acid in March. Is this correct? |
You can feed as soon as new growth appears. Muriatic acid is a corrosive mineral acid with numerous industrial uses, including as a cleaning agent in the pickling of steel to remove rust, leather processing and in work with oil wells. It?s used at home as a cleaning agent in solutions or in the swimming pool to maintain pH levels. It?s even used in the production certain food products like aspartame, fructose and citric acid. Muriatic acid can also be used to strip the outer layer from the exterior of abalone shells to reveal the brilliant red of the exterior shell or inside mother-of-pearl. I don't think it's a good product to feed your hydrangea. Instead, use a general purpose garden fertilizer. |
