Moisture Meters – What Is The Range Needed For Fescue Grass
Q: I seeded fine fescue in September and the lawn looks great. When using a LusterLeaf moisture meter, what is the range needed for watering fescue grass?
A: Inexpensive moisture meters like this are not really designed for use outdoors. They are best used for houseplants. Use one to compare moisture readings over a period of time. You can get some idea of what the numbers on the meter mean by first putting it in a pot filled with soggy potting soil and comparing that to what you get when the meter is put into pot filled with completely dry potting soil.
For your lawn, you’ll get the best information by using a trowel to pull a slice of earth out of the ground to see if it is dry or moist. For your young lawn, the top couple of inches of soil should be kept moist, but not soggy. Use local rainfall amounts plus irrigation to insure the lawn gets 1/4 inch of water per week in winter. When hot weather rolls around, your lawn will need an inch of water per week.
