I LOVE growing mint! I love it so much that I have seven different varieties and am constantly on the lookout for new ones. One of the most important spring chores for growing great mint is to divide it every year. Since we are growing our mint in pots to keep it from spreading all over the garden, it is inevitable that the mint will become rootbound and use up the nutrients in its pot. For me, this happens quickly over the course of a single growing season. Dividing mint every spring not only creates more plants to grow and share, it gives the plant the breathing room it needs to flourish the rest of the year.
