How do you measure water in a garden?
Regarding this, how do you measure water for plants?
Stick your finger into the soil around your plant up to the first knuckle. If the dirt feels cool, damp, or moist, it has enough water. If it feels dry, it may need more water. Use drip irrigation for plants with shallow roots.
Also to know, how much water does a garden use?
While an inch of rainfall doesn't sound like much, an inch of rainfall covering a garden that is 20' x 10' (200 square feet) is equivalent to approximately 125 gallons of water. For a rough estimate of how much water your garden requires, use 5 gallons of water per 8 square feet.
You should check potted plants daily in warm, dry conditions. Usually when the first inch or so of soil is dry, it's a good indication that watering is needed. In summer, watering outdoor potted plants is necessary daily (and even twice a day) for most species, especially when temperatures reach over 85 degrees F.
