How good would a mix of 75% Cleansed Sand/ 25% Miracle Grow be for growing a plant?

Answer 1

You need :

Black Earth for the nutrients,

Sand for drainage,

Vermiculite to hold moisture.

These three, together will give you a balanced mix.

Sand is excellent but not to be used alone. Miracle Grow is what you need to feed a growing plant. Consider it as Vitamins. You did not say what kind of plant.

Answer 2

Does the phrase "That Sucks" ring a bell?

You can make a cheap mix of 75% landscapers mix, 25% expanded shale and you will have a good start. Don't waste time blending in the Miracle Gro.
I work for Scott's so I know first hand how the stuff performs.

Answer 3

I am a firm believer in breaking the rules. I have a great deal of success using the cheap soil from Lowe's. I used to use the organic humus, but they no longer sell that in my area. So I've used a mixture of cow manure and peat with moisture crystals tossed in the middle of the pot. (This is only for home use, I would not use cheap soil if I had a greenhouse!) Use 3 gallon pots if you have them and put the plant in morning sun/afternoon shade or on top of your dryer if you have fluorescent lights you can leave on 24/7 in your laundry room.

Answer 4

If you were going to plant Cacti or succulents that would be a great mix.
