some of my earlies (rocket) after 12 weeks have small ,pin head size white spots on the surface. they taste alright and there is no sign of any blemish under the skin. any ideas please ?

I have also noticed this - (my potatoes are Gourmande). My neighbour thinks it is to do with the gross humidity. It does look like salt & rubs off ok - I am wondering if it is salt!

hi judi
i suppose it couldbe salt but im not sure where it has come from. have you noticed any adverse effects from it ?

some of our rocket had the little white spots, they seem to dissapeer after washing and cooking, ive not notice any effects from eating them

thank you richard. pleased to learn i'm not on my own.

Hello David
I think the white spots that you refer to might be the breathing pores on the tubers, known as lenticels. Potato tubers are modified stems and rely on these tiny soft areas in their skin for gas exchange. They tend to become enlarged in very wet conditions which is why they have become much more prominent this year, in our current prolonged spell of wet weather.
