Can anyone help with something different for 50th birthday present ideas please

[mawi]

It is my bff's 50th birthday soon and I have no idea what to get her. She loves nature and is trying to be more conscious about the climate and is growing her own veg and trying to remove as much plastic from her home as possible so I do not want to buy her anything that goes against these values. She loves music and walking her dog and reading and travelling. My budget is approximately £50 but there is leeway with that for the right gift.
If anyone had any ideas they would be greatly appreciated. Thanks.

Foraging course?

How about a beautiful evergreen plant? Or tickets to a concert?

It's my 50th this year and as I don''t really need any more "stuff" I'm planning on asking people to make donations so I can have 50 trees planted in my name.

Would she appreciate something like that or do you really want to buy her a physical gift? Or you could do both - an oak tree and an acorn necklace?

Some fruit trees ? My pear tree has gone mad this year, so we are giving 🍐 to everyone, that is making me happy

I would currently want tickets to the Pet shop boys gig, but I am happy to go to gigs alone, appreciate not everyone is. If you are in/near london, Manon is on at the Royal Opera house until November, which is supposed to be beautiful and some of the tickets are v reasonable.
