Water for your garden Drip irrigation

The past 3 years have been very dry here in Tennessee and "very" HOT. For the last 2 years I couldnt grow a green bean if my life depended on it. The plants just dried up ..never grew. Well, this spring thank fully it rained soon after planting..I do think timing of planting seed is important too as the past 2 years I procrastinated and planted my beans late and it was already quite hot. I believe planting your beans as soon as danger of frost is over and hopefully the heat hasnt hit yet will insure better germenation. I planted earlier this year and we had some mild weather with rain. But mid june the heat came and no rain. We installed a Micro watering system this year. It consists of 2 in. tubing with 1/2 inch tubing coming off of it and watering directly to your plants. We used sprinker heads and they worked great, but when the plants get bigger you have to move them around the larger stems and leaves or they will block the water reaching to your other plants, also sprinklers water the weeds too. If you use drip tubing directly to ea plant or sprinkler heads close to the ground of your row you will eliminate these problems. We got our system at Home Depot it was a kit with everything we needed for $25. I think you can work up your own system and make it as economical as possible or as extravagant as you want...we added a timer so it would water at 5 a.m. in the morning. Well we have vegetables now we have flowers blooming it took water. My point is water to your garden is essential if you want to have an abundance of vegetables or flowers. I have heard of gardens that just "grow" with very little care but that is an exception. This was the choice we made, there are other ways to get water to your garden ..rain barrels, pumps from a stream or pond.... I have recieved our water bill and although it is not much higher I see the difference and I am calculating is it worth it for me. Good luck.
