Many of my potatoes this year have splits in them, but then the skins have grown over the splits, leaving a very uneven skin. Is there something I have done wrong? We have watered about every 4-5 days.



Most likely the problem with tubers cracking has to do with uneven moisture. One of the ways to moderate soil moisture is mounding soil or hilling up around the plants and having an organic mulch for the tubers to develop without temperature and moisture fluctuating too much.  Click on the following link http://extension.usu.edu/files/publications/publication/HG_Garden_2005-13.pdf and you will see on page 3 a list of disorders and control. 

For information on growing all kinds of vegetables in Utah, a great resource is the horticulture fact sheets that USU Extension has available online.  A quick way to get to those resources go to http://extension.usu.edu/saltlake/htm/horticulture/fruit-and-vegetables and scroll down to find informative fact sheets In the Garden Series.
