Added to any liquid fertilizer, molasses makes it more effective

Molasses, as we all know, is the thick, syrupy juice created by the processing of either sugar beets, or sugar cane plants.

But what many people don't know, is that molasses is a good, quick source of energy for the various forms of microbes and soil life in a compost pile or the soil.

In fact molasses has long been a part of the common products used by organic gardeners to bring greater health to their soils and plants, because it's a great source of carbohydrates that stimulates the growth of beneficial microorganisms.

Types Of Molasses

Now there are many grades and types of molasses, depending upon the maturity of the sugar cane or sugar beet, and the method of extraction that they undergo. The different types are: first molasses, second molasses, unsulphured molasses, sulphured molasses, and blackstrap molasses.

You might also hear about dry molasses which is something different altogether, which we're not talking about in this article. But just so you know, dry molasses is molasses that has been sprayed onto grain residue which acts as a "carrier."

The Best Type For Boosting Fertilizer

For gardeners, blackstrap molasses (unsulphered) is the best choice because it is the most nutritionally valuable of the various types of molasses since it contains the greatest concentration of sulfur, potash, iron, and micronutrients from the original cane material. So it's not just the sugar content that makes molasses useful, but its trace minerals.

Molasses is also an excellent chelating agent, which means that it can help convert some chemical nutrients into a form that's easily available for organisms and plants to use.

The blackstrap molasses (unsulphered) is a liquid molasses that can be used alone, or as a component in both sprays and soil drenches, and can be an important addition to your organic fertilization program.

How To Use

Molasses is excellent when applied to soil in conjunction with organic fertilizers, or sprayed directly on plants.

Basic Mixture:

  • 1 to 3 tablespoons (15 to 45 ml) blackstrap molasses (unsulphered)

  • Added to 1 gallon (3.8 liter) of liquid fertilizer mix (this can be any liquid fertilizer, compost tea, kelp, or alfalfa meal tea)

We talked about alfalfa meal last month, so if you missed it, you can read it here: Alfalfa Meal.

Molasses and Alfalfa Tea Mixture:

4 gallons (15.2 liter) of water
1 cup (225 ml) of fine ground alfalfa meal
1 tablespoon (15 ml) blackstrap or sugar beet molasses

Allow this to brew for 24 hours, then it is ready for application as a soil drench, or as a foliar feed.

Overall molasses is a unique material, and when used properly to help boost other liquid fertilizers, you can see definite benefits.

Planting Depth

As a general rule, most bulbs are planted at a depth that is equal to 3 times their diameter at their widest point.

Tulips like to be planted about 6 inches (15.2 cm) deep and 4-6 inches (10.2-15.2 cm) apart.

Always plant bulbs as soon as possible after purchase to prevent them from drying out.
