I have some "Low nutrient NPK compound fertilizer" which is sold as Citrus Food left over from a Calamondin tree which has sadly passed away.
Can I use this fertilizer on my herbs? They are basil, oregano, thyme, parsley, coriander, chives.
It has nothing on the bottle which says you shouldn't use it on plants that aren't citrus fruit-baring, but will it benefit my herbs much even if I do go ahead and feed them with it?
