Potato Scab and Slug Damage

It’s getting to that time of the year when the potatoes need to come out of the ground.  Ours are earlies (which we planted rather late) and won’t store very well so we are just digging them up when we need to use them.  A lot of them have got potato scab and look like this.

There’s absolutely nothing wrong with them, it’s just purely cosmetic (but this is enough to stop the supermarkets selling them).  This however is not so good.

Holes in Potato

These little holes are a sure sign of slug damage.  It never looks too bad on the outside, but when you cut them open this is what it looks like.

Slug Damage on Potato

Quite often the whole potato has to be thrown away.  The longer the potatoes stay in the ground, the more likely they are to be damaged by slugs.  So it’s potatoes with every meal for the next couple of weeks!  If you’ve got maincrop potatoes, and you haven’t done so already, it’s probably worth lifting them on a dry day and storing them somewhere cool and dark.  That’ll stop the slugs getting to them.


Earthing Up Potatoes

Our potatoes have reached the stage where they need to be earthed up.  We plant ours at the bottom of a trench, so that we just have to fill the trench with soil when we earth up.  This somehow seems easier than piling the soil up around the stems.  I left the top 5 inches of plant sticking out of the top.  Here are the before and after shots.

Hopefully this earthing up will prevent us from getting any green potatoes (don’t eat the green ones as they are poisonous!).  As the plants get bigger, I’m going to keep a sharp eye out for any flowers as I read somewhere that removing them can increase your yield.  Can’t wait till we’re digging them up – home grown new potatoes are just so delicious!
