I had the 2.5 acre field power harrowed on Monday morning and got straight to work planting the early potatoes. I opened up a drill using the wheel hoe with a ridger attachment which I also used to cover up the drills.
In the above photo you can see the wheel hoe with the ridger attachment. The other tool is a row marker.
The varieties I planted were Home Guard and Duke of York for 1st earlies and British Queen for 2nd earlies. They were planted 12″ apart in drills 30″ apart. I planted 1000m2 (.25 acre) in total.
