Andre CampbellThis might seem a bit strange, but molasses can have many benefits for your soil. If you’ve looked at compost tea recipes, you might have noticed people recommending adding molasses.
It is an excellent addition to your organic gardening. It has nutrients and beneficial sugars that can help your plants thrive.
What Is Molasses?
This substance is a byproduct of sugar production. It is what gives brown sugar its distinctive color and flavor. A few types are available, but you only want unsulfured blackstrap molasses.
Blackstrap has more nutrients that boost plant energy and encourage growth. Dried molasses is much easier to use in gardening.
Can Plants Use This Sugar?
Plants can’t take up the complex sugars in molasses, but they can take up what the microbes in your soil break the sugars down into.
Remember, plants produce carbohydrates through photosynthesis. The sugar in molasses will help your soil. It will feed beneficial microbes that pass on essential nutrients.
You can also add molasses to your compost to increase its nutrient content and boost it, as compost starters do.
How to Use Molasses in the Garden for Plants
Horticultural molasses has many benefits for plants and organic gardens. Its liquid form is mainly added to water or liquid fertilizers to increase their nutritional value.
Dried molasses can be sprinkled to benefit the soil and compost. It doesn’t need to be applied more often than other fertilizer treatments.
If you’re adding molasses to the soil, you only need to do so once a year, and twice if your soil is very poor.
1. To Improve Soil Health
Healthy soil is the foundation of a good garden. Ensuring your soil provides all the nutrients your plants need can give you a rewarding gardening experience.
Harmful pests will target weak or sick plants, but keeping plants healthy can help prevent many infestations.
Potassium, which this substance contains, is essential for healthy growth. If lacking, you will notice lethargy and plants that cannot handle the cold or poor weather when they should be just fine.
Keeping helpful microorganisms alive allows them to break down nutrients from molasses. This process converts those nutrients into forms your plants can use effectively.
Sprinkle 10 to 20 lbs of dried molasses per 1,000 square feet of garden or lawn and water generously. Alternatively, use 1/2 cup of liquid molasses in water for the same space.
2. Fertilizer
Molasses liquid is rich in potassium, calcium, iron, magnesium, phosphorus, and other key micronutrients. Adding it to your soil as fertilizer helps your plants gain more nutrients.
Combining it with organic liquid plant fertilizers or compost teas can also boost the nutrients it already has. It adds extra iron, which produces chlorophyll.
The extra potassium also strengthens the plant’s ability to fight diseases and improves crop yields. Many recipes for liquid fertilizers already include molasses.
Some gardeners have also had good results using molasses for tomato plants. It gives the plants a boost of energy and makes the tomatoes sweeter.
Other plants that benefit from molasses include melons, cannabis, peppers, and eggplant. However, when diluted with milk, it works best on eggplant, melons, and peppers.
To make molasses fertilizer, mix two tablespoons with 1 gallon of water. Apply it once a week by pouring it on the soil or spraying it on the plant leaves.
You can also mix it with Epsom salt to make homemade fertilizer, improving plant root health and increasing flower production. Combine 2 tablespoons of liquid molasses with 1 tablespoon of Epsom salt and 2 gallons of water.
Let the mixture dissolve, and use it to fertilize your plants.
3. Add to Compost
The sugar in this product is excellent for feeding beneficial bacteria.
You can add it to your compost as a compost starter. Adding it occasionally will also encourage good bacteria to stick around.
Dried molasses is the easiest to use here; occasionally, toss a handful into your compost pile. You can also add a small amount of the liquid form to water and sprinkle it on.
4. Add to Water
To mix molasses with water for your plants, combine two tablespoons of liquid molasses with a gallon of warm water. This recipe makes a good mixture, with a ratio of 1 to 3 tablespoons per gallon of water.
Feed the solution directly into the soil around individual plants or spray it over a large area in addition to regular watering. Plain molasses water will give your plants an extra boost of energy.
How often should you apply it to your plants? Apply molasses water to the plants every two weeks in addition to regular fertilization.
5. Pest Control
Molasses can be used as a natural insecticide. Just 1.3 mL in 1 liter of water makes a powerful insecticide foliar spray that won’t harm your plants or any animals that visit your garden.
Due to its high sugar content, sugary treats kill many garden pests. Some insects, such as aphids and mealybugs, become severely dehydrated after feeding on them.
Eating the product will kill the insect. It will draw water from its gut, dehydrating it.
Also, spreading 10 to 20 pounds of dried molasses on 1,000 square feet can help control pests. This includes grub worms and root-knot nematodes.
It will also keep out animals like moles and armadillos that eat grubs.
6. Weed Control
Molasses can help control difficult-to-control weeds like dallisgrass.
For this molasses spray recipe, mix 1 cup of liquid molasses with 1 gallon of vinegar or water. Then, spray the solution onto the plant’s crown.
The mixture increases microbial action, preventing seeding and breaking down stubborn root systems.
Why Dried Molasses?
Dried molasses is easier to handle and use for agricultural purposes compared to liquid molasses. Liquid molasses is very sticky, making it difficult to measure accurately.
The dried stuff has all the benefits of the liquid in a much easier-to-handle form. You only need about ¼ teaspoon for most compost tea recipes, which means it should last a long time.
Where can I buy molasses for plants? You can find it in dried and liquid forms online or in some gardening stores.
Takeaway
Now that you know how to apply molasses to plants, don’t be afraid to try it. It can be a great addition to your gardening routine.
