If you have missed the thunderstorms and showers in central Indiana, here is a good rule of thumb to follow when garden soil drys up. Most flower and vegetable gardens perform best when they
receive 1 to 1-1/2 inch of water per week. Supplemental watering is best done in the morning and delivered directly to the soil surrounding the plants. Soil type does not affect the amount of total water needed but does dictate frequency of water application. Lighter soils need more frequent water applications, but less water applied per application. Good luck and good gardening and may mother nature take care of all of your watering needs..
