Okay thanks for this info, ill check thetortoisetableI'm not very confident when it comes to IDing plants so always tend to be very cautious and don't feed anything I'm not 100% sure of but here's my thoughts.
The second picture (and possibly the first) could be lesser celandine in which case do NOT feed.
The fourth maybe sow thistle which would be ok to feed but double check that.
Now you have some names to go on check them on www.thetortoisetable.org.uk - that will tell you what is safe or not.
Hopefully someone much more experienced will be able to help too.
I've put a leaf identification chart from Wikipedia on this thread which makes describing plants easier when you do an internet search.Okay thanks for this info, ill check thetortoisetable
