The potatoes (a first early variety) are proving to be not only tasty in the way only home grown potatoes are but also free from marks and blemishes. I think this may be due to the improvement we have made to the soil and other steps we have taken.
Wire worm were a problem we had a couple of years ago. You could still eat the potatoes we had grown, but they were not as attractive looking as they might have been when you harvested them. It also meant a little bit longer prep time before cooking them. Wire worm are more likely to be a problem when you grow potatoes in an area that was previously un-worked and grassy. This means it is less likely in future years but you can try growing the green manure seeds -(mustard) in an area where you plan to grow potatoes.
Ways to prevent potato problems in own grown potatoes in future.One of the things I did to reduce the risk of wire worm in the future was to sow green manure seeds of a type that are supposed to help deal with wire worm problems. I did this in the area that I would be using to plant potatoes in future.
- I grow by organic principles so the green manure sowing fitted with my ideas of dealing with problems in a natural way.
- I also use the principles of crop rotation and leave the correct gap of time before replanting the same crop in an area.
- You can buy a varieties of seed potatoes that are resistant to the problems you have suffered from. These are things like a resistance to scab resistance.
- Grow good quality seed potatoes, do not plant supermarket spuds sold for meals.
