Jacks Classic logo

Professional formula for more flowers and brighter colors on all indoor and outdoor plants.
Feeds through both the roots and the leaves.

We developed this formula over 40 years ago for the professional Orchid Grower to help his plants set abundant buds that matured fully into vibrant, beautiful and colorful flowers. The 1-3-2 ratio is still the ratio that is preferred by professional growers when they want results. This formula also contains a higher level of magnesium, a vital secondary element, which helps keep leaves green.      
 

Blossom Booster 10-30-20 All fertilizer labels must follow the same format according to the state fertilizer laws. In Blossom Booster 10-30-20 the first number is for Nitrogen. This product contains 10% Nitrogen. The second number is for Phosphate. This product contains 30% Phosphorus as P2O5. The third number is for Potash. This product contains 20% Potassium as K2O. These three elements; Nitrogen, Phosphorus and Potassium are the major elements in any plant food.

Carbon, Hydrogen, Oxygen, Calcium, Magnesium and Sulfur are the secondary or minor elements. The water, soil and air provide most of these elements to your plants.

Manganese, Iron, Copper, Boron, Zinc and Molybdenum are the trace or micronutrients. All Jack's Classic® products contain these trace elements. Although they are present in small amounts, they are just as important as the major and minor elements in making your plants grow. The guaranteed analysis on each package of fertilizer tells you how much is in each product. Jack's Classic® products contain these elements in a highly soluble form which means they will go completely into solution in water, and when applied to your plants, they will be taken up and utilized to make your plants grow to their fullest potential.

Understanding fertilizer
by the numbers

To get the best results you possibly can from your fertilizers you should try to understand the numbers, I hope the following helps.

Have you ever wondered what the 5-10-5,  the 20-20-20, or the 0-46-0  stands for? If your like most people you do not understand these numbers, and guess when it comes to choosing the right plant food.

To help you understand how to choose the right fertilizer try to remember this little saying. "UP, DOWN, ALL AROUND"... Let me explain. The first number is nitrogen this effectively pushes up growth or foliage as you know it. The second number or middle number is phosphorous and  concentrates on down growth or root development. This number also has an added benefit for promoting more flowers, hence the saying "root and bloom". The third number, potassium has beneficial effects all around, another words it offers a little bit of everything the plant needs to stay healthy.

Now that you know what the numbers do, you need to use logic and common sense when applying fertilizer. For example, if you are going to repot, transplant, or disturb a plants root system, make absolutely sure the middle number is the highest and the first number is a minimal amount, something like 5-50-17. This will insure you promote new root growth while applying a minimum amount of demand on the plants desire to grow new foliage. If you have a well established plant and want to see it get bigger concentrate on a more basic fertilizer that has a higher first number. The fertilizer chosen should offer the specifics the plant needs.

One of our favorite fertilizers is Schultz plant food, it is a liquid concentrate and works on a wide variety of plantings. For promoting bloom or root we'd prefer a Jack Peter's product called Blossom Booster. (below) For best results use a couple of different types of fertilizers like maybe fish emulsion as an organic and Schultz, then alternate them between feedings.

As I said, I hope all this helps, and remember read the products directions and never over feed as this can be worse than not feeding at all.

Happy Growing !!!
