NETTLE FERTILISER FEED
I have about 20 litres of quite concentrated nettle fertiliser and I would like to know the following please
How long can it be left for in plastic screw top bottles?
Are there any plants in particular vegetables which I should not use it on?
Many thanks, John

If its been in the dark should be fine. I would suggest
one part fertiliser to 10 parts water to be on the safe side.
Once every 6 weeks is the usual format.
Use Ericaceous fertiliser on those plants listed on the
packet, not nettle fertiliser.
