What the hell is an inch of water?!?

Information on growing various plants often recommends so many inches of water a week. So what the hell is an inch of water? What are the other dimensions?





Is this especially for 1-dimensional tomatoes?

To find out what an inch of water is you should purchase a rain gauge and set it out on your lawn with your sprinkler on and record the time it takes for water to reach 1 inch on the gauge.rain gauges are very cheap.
Reply:gardening wise an inch of water is about equivelent to 1 gallon of water per plant per week
Reply:An inch of water is just that; enough water to fill a pan with 1 inch of water if sprinkled on.





You measure the watering of a lawn by setting out shallow pans and turn the sprinklers on and let them run till an inch of water has collected in the pans. You time that sprinkling and you know how long to let them run to give your lawn the required amount of water.





Set a pan by the plant and sprinkle it till you get an inch of water in the pan. If the plant needs 3 inches of water a week, then water it 3 times a week with 1 inch of water.
Reply:Take an empty tuna fish can (it's about an inch tall), set it in the yard or garden, and water until the can is full. When watering indoor plants, make sure you have a drip pan or saucer underneath the plants, and water until it drains out of the bottom of the plant and into the saucer. Most indoor plants won't need an inch of water, and will not need to be watered more than once a week. You can get a "moisture meter" at most garden centers. It's a device that you stick in the soil, and it registers how dry/wet the soil is. Just make sure you are familiar with the watering needs of your plants. Overwatering kills more plants than underwatering.
