I have just a few roses so I don't always use up the fertilizer in one summer. Can it be used the following summer or do I have to buy fresh? I haven't been able to find an answer anywhere. Thanks!
Rose Fertilizer Good Year to Year?
Your fertilizer should be ok to use. If it's a water soluble and caked, just mix it with a little hot water to dissolve before diluting. If the fertilizer has gotten wet, it's potency may be slightly diminished, but it is still usable. Always use according to package directions.
Well if it nonorganic and from a box store and looks all crusty at the opening,I would rebuy but if its oraganic dont worry.Remember roses like acidic soil compared to akaline soil. Good Luck
