I was bought a potato vine last year with lots of flowers in. I planted it in a pot and placed it in a rather shady spot. This year it's had very few flowers and there are none at present.
After googling I realised it probably isn't getting enough sun so I've moved it to a sunny area now. Will it flower again this year? Would it help if I pruned it? It has put out a lot of green growth instead of flowers.
