I planted a yam last March just to see what would happen. We live in Lake Havasu. For over two months...nothing happened at all. Then It started to sprout. I now have several vines trailing around my garden area which are 15 feet or more long. I've been trimming it back because it's gotten so big.
Has anyone here grown yams or sweet potatoes before? Will it produce yams? When should I expect to start digging around for them?
