What is the n-p-k for this product? i'm surprised it's not mentioned in the product description. thank you.

Definitely NOT 10-52-10. This product is the 5.5lb box. It's npk is 15-30-15. This is not mentioned in the description which it should be. I bought this thinking it was 10-52-10. I'm totally bummed because this is the 2nd time I've placed this order only to find that the npk is either not mentioned or is different. NOT COOL!!!

Why is this superior to regular Miracle-Gro for flowering window baskets?

Fertilizers have three numbers: NPK: Nitrogen(N)-Phosphorous(P)-Potassium(K): Nitrogen assists the plant grow more leaves, Phosphorous is good for flower production, and Potassium is good for overall health of the plant. The regular all purpose Miracle Grow's numbers are:24-8-16 whereas the Bloom Booster's ratings are: 10-52-10. Bloom Booster has relatively more Phosphorous; thus it is expected to help the plant to grow more buds and fruits. I use it about 1/3 rd spoon ( a weak solution) per gallon for my container plants almost alternate days with great results.

is this product good for vegetable blossoms and setting fruit

Absolutely! The Bloom Booster is heavy on the nutrient that 1, develops roots and root systems and 2, helps in the development of the blossoms/flowers that develop into fruits and vegetables.

Can it be used for indoor pot plant?

What kind of pot?Works great for me.Youcan also spray on leafs,but not when flowering.
