Sweet potatoes are not much different than a regular potato in terms of growing them. Take a half of sweet potato and suspend it like you did the avocado seed. After a few days, you will start to see roots and once these get to about four inches, break them off and put them in water. Once roots grow to about an inch, just plant them in the ground.
Ginger is one the best fresh herbs to have on hand and it is easy to grow. Take a spare piece of the root and plant it in potting soil. After about a week, there is generally enough growth to use the ginger. Just keep repeating this to ensure a plentiful ginger supply.
There you go! having this in your back yard will not get you running to the supermarket or market 🙂 how amazing that will be and saves us whole lot of money…
