Hi Declan. Here in the south of Scotland we don't make hay until July as there isn't enough bulk in the grass before that - and this year being dry we will be struggling to make good hay at all I think. You are about on the same latitude as us but it would be best to check out what others around you are doing. In the best of weather - dry and breezy - it takes 5 days to cut, make and bale hay, 4 days in a super year. If you can't get someone to mow your crop, you will have to scythe it - try to do it neatly so it falls in rows which will make it easier to turn. Leave it to wilt then turn it with a pitch fork every morning - you will see as it 'makes'. It is done when there is no moisture left if you twist a bunch in your hands, but it should still be a pale green and smell sweet. You could stack it loose or you could tie it into bundles with a single string then leave it stooked to air before you cart and stack it. Tied would make it easier to use afterwards. Handmade hay is far less broken and bruised than mechanically made hay so keeps more of its nutrition, so if you have the strength then go for it. Let us know how you get on.
