Every year I grow spuds in a small garden and every year the plants become
huge while I'm left with only a small crop (usually one giant potatoe and
four small ones from each plant). It seems like each plant is putting most
of its energy into the greenry and not much into the spuds. I'm using Russet
Burbank, late maturing seed potatoes. I should get about 40kgs of spuds
(according to the seed manufacturer) but am lucky to get 10kgs. The soil is
great..add compost and steer manure every year and use a veg fertilizer
every two weeks. Any advice would be appreciated.

Russet Burbanks are a litle more particular than many other varieties. You may
need to try a round early season potato depending on your location. The other
possibilty in that you have too much nitrogen and not enough potash.
