Why was Louisiana so difficult to recover after the Civil War ?

The Louisiana economy as were the economies of several other states was based on plantation slavery and there were no more slaves to raise cotton and other crops such as sugar cane. The people of Louisiana lost all of their money during the war so capital was also scarce. And southern railroads which were not destroyed by Union armies were worn out form over use and lack of maintenance during the war. All of the wealth that had been built up since the country began was simply gone.
