Potatoes take about 80 to 100 days to grow.
Harvesting is usually in August & September.
Other crops grow faster.
Russia has lots of land for crops.
I imagine the issue is personnel and fertilizer.
The fertilizer issues in the US have resulted in less than optimum crops. It’s noticeable in the produce section. Stuff is just smaller than it used to be.
Because of the lack of fertilizer and Ukrainian wheat crops, we should see some food issues in Africa later this year.
This is not new. I take most of what seems “hyperbolic” with a large gran of salt. But long term disruption caused by the war is inevitable. But Russians tend to be stubborn to a fault. Oh well.
25% of the people raise their own. They can be stored.
