I have some comfrey/nettle tea left which I made in May. I’m wondering if it’s okay to still feed some of my tired looking shrubs with it at this time of year, and if it is possibly too old after 5 months brewing?
If you have a compost heap you can use the comfrey tea on it. It is very good for halping to break down leaves. Or you can just keep it. Some of the nutrient value is lost as the tea ages because some decomposition takes place but it is still useful.
