Q:how long do my dogs have to stay off

Answer This Question

A:  Hi Josh, We recommend keeping pets out of the area until the application has fully dried. Thanks!

by|Sep 25, 2019

    A:  After it is watered or rained it will become part of soil. You will not be able to see it then it will be safe for animals, but animals are not necessarily good for garden or yard

    by|Sep 26, 2019

      A:  Generally, it comes as granules or a power that you have to mix into the soil. I think this one is the granules, so once you spread it, water it in and let it dry. You should have no problems with it interacting with your animals. It is a mineral, so they would not want to eat it.

              Answer This Question

              A:  Maybe you could think about using some soil to fill in those standing water areas of your lawn, which would probably make for a healthier lawn, if possible. Your question itself, I can't answer, sorry, but I'm for getting rid of areas that hold standing water.

              by|May 29, 2019

                A:  Hi Matt, We recommend waiting until the areas with standing water subsides before applying the product. Thank you.

                by|May 29, 2019

                  A:  The moisture will release the mineral into the soil. I would wait until the ground is just wet and not with standing water or else it might dilute it too much..

                  by|May 27, 2019

                  A:  If you have no risk of rain running it off, yes. It will be more effective if you let most of the water evaporate.

                  by|Jun 2, 2019

                    A:  I suggest waiting till the area dries up !

                      Answer This Question

                      A:  Hi Westy, Gypsum can help leach the salt away from the top levels of the soil, as it can make soil more porous. However, it will need to be heavily watered in order to do this. Thank you.

                      by|May 29, 2019

                        A:  Yes it can.

                        by|May 21, 2019

                          A:  Not sure. Its main purpose is to soften the soil so water can penetrate deep down. Use on my lawn , got green and lush within a week

                            A:  I do not know the answer to this question. I would suggest you go to the Pennington website and see if they have an email support option so that you could pose this question to the company..

                                Did exactly what it says it will do. Helps green up grass in heavy clay soils, and helps loosen the clay. Grass greener up within a couple days of application and has stayed green.

                                It did not meet my expectations. I did not get the improvement of the soil as I expected.

                                Hard to tell since it takes a couple of years of doing it for results, (2 times a year for 3 years); but it seems to be the best out there and was packaged well..
