Grass does like a plentiful supply of water, as long as the ground is free draining and not prone to water lodging. But if you are wondering whether rain water is preferable to mains tap water, then I would have to say yes. Although I have watered many, many different and varied lawns with tap water with no detrimental effect, rain water does have 3 extra benifits. 1. Due to atmerspheric pollution rain water is usually slightly acidic which lawn grasses prefer, as opposed to tap water which is often slightly alkaline. 2. It is usually at a more ambient temperature than tap water (especially if it is from a stored source above ground) and is therefore less likely to shock plants, grasses included. 3 It's more economical and enviromentally sound, your grass will grow stronger knowing that it is being husbanded in a more sustainable way.... maybe!
Alcohol is poisonous. Slugs, being small, are more affected, so beer will kill them. Alcohol is a poison to humans, too, and if you drink too much, it will kill you, too. Beer in moderate doses is OK, but too much is bad.
Too much fertilizer can overload the grass with nutrients, leading to excessive growth that weakens the grass and makes it more susceptible to disease. It can also leach into the soil and contaminate water sources, causing environmental harm.
It may but it won't kill the weeds. It the same way hot water burns you if you get scalded by too hot a water supply from the spigot. Grass seed has a heat limit or it cooks and kills the baby.
Yes, both can.
Of course. Too much anything can kill you, even water.
Cutting grass too short can weaken it and make it more susceptible to stress, disease, and damage, but it typically does not kill the grass outright.
too much water too little water too much fertiliser not enough fertiliser herbicides amongst other methods
yes, it will kill them
Watering your lawn when its raining can cause too much water. Grass does not have to be constantly watered. Much like you and I, too much water can be harmful to our bodies.
Water can kill you if you drink too much of it at once. This is called Water Intoxication and it can be lethal.
Yes, cutting grass too short can damage the grass and potentially kill it. This is because cutting it too short can weaken the grass's ability to photosynthesize and grow properly, making it more susceptible to stress, diseases, and pests.
The best time is in the early morning. If you water at night the grass could catch a fungus disease. If you water during the day some water gets evaporated so you have to use more water. Early morning is best.
