Regrowth of a Leek from kitchen scraps
There is no need to throw out the ends of kitchen scraps from many vegetables because they can be easily grown to provide an endless supply. There is a product which you can use for this called regrow. They have kindly provided advice and photos of a leek growth over just a week.
The harvest differs from leek to leek and depends on the size of the leek. Regrow can be placed on many glasses or vases, one already have at home. Place the glass or vase in a bright place and change water every/ to every second day.
