I couldn't agree more, vegetable gardening brings peace, joy & happiness to many home gardeners especially come harvest time. Is it the key to happiness? It sure is!! Being able to harvest your own home grown food from your own backyard is a truly rewarding experience. Gardening is also a very therapeutic activity that has positive health benefits, reduces stress and offers an escape from a noisy, hectic busy life we all live. If you're looking to add some more happiness in your life or looking for an escape and downtime from a fast paced world we live in consider growing vegetables in your outdoor garden. You can also grow some indoors as well. You'll be glad happy you did.  Your mind body & soul will thank you for it!
