The main reason is because IF you are a serious gardener you strive to build up your soil. And a built up soil has lots of organic material in it. MG destroys the organic matter and when this happens the soil microbes which break down the organic matter are destroyed as well. When soil microbes are destroyed the only thing which feeds the plant is MG. Organic fertilizers feed the soil, not the plant. And in doing so in a natural way you will have far fewer problems such as diseases and pests. MG is not a forgiving product either. Use too much and you damage or kill your plant. Use to little and the plant gets very little nutrition. MG leaches out of the soil very easily, especially in container grown plants. If you use the same soil year after year the soil dies and you have to use more fertilizer to make up for the lack of soil microbes. And more fertilizer the next year and on and on it goes. Have you ever heard the term "burned out farmland?" The soil is dead because of the use of chemical fertilizers of which MG is. There is a scientific term for a difference between organic fertilizers and chemical fertilizers. It is called Cation Exchange Capacity. This is a rather complicated subject but I will try to simplify it. Organic fertilizers have positive charged ions called cations. Chemical fertilizers have anions and are negatively charged. Cations cling to soil which means it doesn't leach away like anions in chemical fertilizers do. This is why chemical fertilizers have such high NPK numbers and organic fertilizers have such low numbers. So actually when you buy MG you are paying for something that will not and cannot be used because it leaches away everytime it rains or you water. When organic fertilizers are used on a continuous basis year after year you actually need to buy less and less fertilizer.I have used Miracle Grow in the past and had very good results. I have been told to throw that JUNK away. WHY?
Be very careful of any cattle or horse manures. It is very possible that this manure is contaminated with Picloram, a chemical herbicide used on hay fields. The animal eats the hay and the chemical passes through it. This chemical persists in soil for months if not years and will destroy any plants you may wish to grow except grasses. Most commercial hay growers use this product. A simple test is to fill a bucket half full of the manure and then finish filling it with water. Let it stand for a couple of days stirring occasionally. Then pour this liquid over a weed such as a dandelion. If, after 72 hours the weed shows no detrimental signs it is safe to use. But, getting manure from different animals all in one batch complicates this little test as one animal's manure may be OK and another animals manure contaminated. You've gotta be careful using raw manures in the US.Thank you for your very informative post . I have ceased using MG on my raised containers and will use up what is left on my pasture land. Once won't hurt it and its all weeds anyway. No cattle, no crops, no chickens or turkeys. just me n my new tractor.
Thanks, Tetters, for the horse poop tip. I have some cow manure and horse manure, available from The Agriplex here . I think I can get them to dump a load right in my pickup.
Well, there goes another otherwise useful and informative thread @Esther KnapiciusI prefer to use natural stuff. although, at some house auctions my husband will bring home some of the miracle grow he has gotten in just a box lot for really cheap, so we use it. Cheap as in $2.00 for many boxes.
No one has said it didn't work. It works fine IF USED CORRECTLY. What everyone is saying is to look at all of the negatives when using this stuff. A serious pollutant and a soil destroyer. These are proven facts. And it is not just Miracle Grow, it is ALL chemical fertilizers.Here is the thing, go to any large nursery and look above their plants. You will see a tube and that tube is attached to a fertilizer tank. So if you buy annuals or vegetables you are buying things that have been grown with the likes of Miricle Grow. If it didn't work and work well they wouldn't use it. If they didn't use it then their plants would look like what the average gardener has in his or her garden a month after they plant their previous beautiful healthy plants. That is the answer for all those that ask why their plants don't look as nice as they did when they bought them. A nursery can grow 50,000 beautiful healthy plants but the average person struggles to grow a handful of plants. As far as anything else, as I have said, no matter how often or how loud you say something it doesn't make it true. To get straight facts before turning on your computer call your local cooperative extension. The internet is full of misinformation and personal opinion. Yes, this is my personal opinion but go to a nursery, look at their spring plants, and decide for yourself whether Miricle Grow works or doesn't work.
