Blow Up Swimming Pools

My cousin and I are always at the house of our grandparents during the summer. This summer, we want to buy a pool and put in our yard grandparents because it is very flat and is a perfect place to put a pool! My grandfather would not let us put it in his court because he is afriad it will ruin the grass. We are trying to convince him if we get a blow up pool, we can deflate every time we have finished using it so it will not hurt the lawn.

My question is if we put the pool in the grass for how long would it take for the grass to die?

Unfortunately, it would only take a few days until the damage to the grass. Maybe if you let up for one or two days at a time, and then the next time you set up you could put it in a different location. Remember, filling a swimming pool takes a long time, it depends how big it is.

Good luck, and (potential) of swimming!

It will only take a few days for lack of light and the weight of the water to start to turn yellow grass.

3 days full of shadow is quite ok. If you move, the grass will recover. Unless the spot is shady to begin. It's shadow now, so maybe just one or two days.
The grass will not really die, but not dormant until conditions improve unless its covered for a longer period.
Note that I have an inground pool. For the last 5 years I have been cons-stream (filter cleaning) and dumping the water rights on the lawn. The lawn has never been as healthy as now! In other words, the vast amount of water spilled in a flood in the soil and roots to learn to go down and get enough - to make the lawn BETTER after than before the pool was there.

Ummm ... Would not it an incredible waste of water?? Your grandparents will foot the bill for it. So maybe the grass die is not the only problem with the idea.

Although empty all the water in the yard can not kill the grass, he often flood their backyard. Not sure whether they would like.

It will take several days for the grass to die in the pool is about this, but the amount of water being splashed and children running on it or even walk on the lot could create a muddy area. Too much water can kill plants too where she drowned. It also depends on the size of the pool and in the amount of water it contains.

yes they will get ruind
