给草坪浇水的正确方法

可以 you enjoy a green lawn in summer without an expensive water bill? Let’s discuss how you can make every drop of water count.

让你的草坪保持绿色和生长, it needs about 1 inch of water per week from you, 降雨或两者的结合.

来测量一英寸的水是多少, set a group of flat-bottomed cups at 5- to 10-foot intervals from the base of your sprinkler to the edge of its reach. Measure the time an inch of water takes to fall in the cups. 以此作为基准时间.

Set a group of cups away from your sprinkler to measure the amount of time it takes for 1 inch of water to fall.

水很深的. 

Giving your lawn a big gulp of water is better than giving it a series of sips. 有水的地方就会长根. If you water deeply, you will develop a deep root system. 另一方面, if you only sprinkle the surface of the soil, 您将创建一个浅根系统.

If you have a clay soil, irrigate only once or twice a week. Sandy soils can’t hold a full inch of water, so we will need to split the application to two or three times a week.

Split applications are also a good idea if you see water running off from the lawn (for example, 在一个倾斜的景观上). We want the water to be absorbed and not to run off.

清晨喝水. 

The grass plants will be active and will absorb the water they need. Any extra water will evaporate, keeping the grass blades dry and preventing diseases. Watering during the middle of the day is not recommended since much of the water you apply will evaporate before the plants absorb it. Watering is the evening is not recommended since the lawn will stay wet all night, 导致疾病.

割正确. 

这有很大的不同. Mow tall and let the grass clippings fall. Tall turf naturally develops a deeper root system. The tall grass blades and the grass clippings will shade the soil, keeping it cooler and conserving moisture. The first lawns that turn yellow in a neighborhood are lawns that are cut short and where clippings are collected.

监控你的自动计时器. 

These “set it and forget it” systems are convenient, but they sometimes irrigate the lawn when it’s not needed. 只有在草坪干燥时才灌溉. Don’t irrigate when it’s raining or when rain is expected. Rain sensors and soil moisture sensors are available that prevent irrigation systems from running when rain is falling or when the soil is moist.

改良土壤. 

添加有机物会有所帮助. The next time you aerate the lawn, fill in the holes with some compost or peat moss. In clay soils, this organic matter will open the soil, helping water infiltrate rather than run off. In sandy soils, this organic matter will help the soil hold onto the water before it drains away.

使用天然替代品. 

You have the option of not watering your lawn at all. Your lawn will turn yellow gradually and go dormant. Going dormant under intense heat is natural for lawns. Lawns will turn green again in the fall when temperatures cool.

不管你是否灌溉你的草坪, you can have a healthy lawn without breaking your bank account. Irrigate only when needed and make every drop count.
