How much should I charge for grazing?

[LividofLondon]

[whinge alert]
Over the past 4 or so years I've let a neighbour graze her ponies and sheep in my paddocks for free. I was really rather depressed at the time so was just happy to have the grass managed as this was then one less thing to worry about. But now, after yet another Christmas where she didn't even think it would be nice to give me a card or a bottle of wine as a thank you, I'm not feeling so generous. This isn't helped by her promise of some lamb and a few quid towards the water trough not materialising. I don't get the impression she and her DH are hard up either, so I'm feeling a bit resentful TBH [/whinge alert]

Consequently I want to start charging for the grazing but have absolutely no idea how much to ask for. One paddock is 1 acre with a metered water trough. The fencing on one side is a little rickety but has been made secure with electric tape. The other paddock is about 1/4 acre, has new fencing but no trough. TIA for any advice.

Oh god I feel really fed up now. I left her a voicemail message yesterday saying I could no longer afford to let her have the grazing for free and would she give some though on what a fair amount to give me would be. I also mentioned that the deal is between me and her and that if her friend wants to use my paddocks too she would need to come and have a chat with me. Anyway, she didn't call me back so I just called her again. I asked if she got my voicemail and she said she had. She wasn't at all chatty on the phone (sounded a little "off" - it was quite an awkward conversation) and said it was down to me to tell her how much I want. I explained that, as a horsey person who has paid for grazing before, she was in a better position to price it up than me. So it's been left that she would talk it over with her husband and get back to me. Not getting back to me has really irked and now I'm just thinking I want her to remove her animals and I'll let someone else have the grazing. F**k it! All this could've been avoided for the price of a bottle of wine each year Sorry, I just need to unload.

She is royally taking the pee.If it was my grazing,I'd be blunt [horsey people are notoriously blunt so I wouldn't worry about offending].I'd just say that as she appears to be unhappy about the arrangement,it is best that she finds somewhere else to avoid bad feeling.Then give her 28 days notice in writing.

People will bite your hand off for 24/7 grazing,especially in winter.So many yards make owners keep their ponies in from Nov to March to save the land from poaching.

has any sort of agreement been reached yet livid?
