Owning a house in true countryside of Poland - stories [692]
You need to spray spuds to prevent blight the disease is airborne and will thrive in the right weather conditions. Warnings will be issued by various organisations in Poland, you can sign up for email alerts. The correct weather conditions for blight are a warm and humid atmosphere. The best organic compounds preventing blight are copper based, dithane is used commercially. I use Bordeaux mix which is a copper based powder you mix with water and spray directly onto the plant leaves. It's major disadvantage is that it's washed off by rain and a second spray is required. Some years you don't have to spray.
Rotating crops is to prevent soil based problems for example growing spuds in the same place year after year encourages pests like eel worm to flourish. Brassicas like cabbage, sprouts, cauliflower etc should be planted in the potato patch the following year not the other way round. Earthing up spuds encourages more tubers as they come from the side shoots of the roots and protect the plant from late frosts. Spuds are easy, when earthing up which you do about two or three times a season you can kill the weeds by cutting their roots and turning them into the soil where they will die.
Tomatoes are the same plant family and also suffer from blight, you treat them for blight the same way you do spuds. I don't think Blight is as big a problem in Poland as it is in Ireland. Get your spuds into the ground as soon as you can in case you can't visit due to the election queues and let nature take its course.
