I have been fascinated with gardening and growing plants of all types. My parents and grandparents had green thumbs and grew all types of flowers, fruits and vegetables. I have always followed the "old ways" practiced by them and to the maximum extent possible have tried to avoid the use of chemicals in my garden. I hope to be able to help others to do the same.
