Common Fertilizers

BANANA PEELS  –  Eating a banana helps replenish lost potassium. Roses love potassium too. Simply throw one or two peels in the hole before planting or bury peels under mulch so they can compost naturally. Get bigger and more blooms. I also use banana peels on my vegetables.


COFFEE GROUNDS  – Acid-loving plants such as tomatoes, blueberries, roses and azaleas may get a jolt out of coffee grounds mixed into the soil. But more likely it’s the nitrogen that helps. Sprinkled on top of the ground before watering or pour a liquid version on top of the soil. If using as a soil drench, soak 6 cups of coffee grounds in a 5 gallon bucket of water. Let it sit for 2-3 days and then saturate the soil around your plants.

EGG SHELLS  – Wash them first, then crush. Work the shell pieces into the soil near tomatoes and peppers. The calcium helps fend off blossom end rot. Eggshells are 93% calcium carbonate, the same ingredient as lime, a tried and true soil amendment! I use eggshells in my homemade potting mix. This gives me healthy, beautiful fruits fit for seed saving. Get the 7 Secrets to Saving Tomato Seed in the Home Garden.

MOLASSES – Using molasses in compost tea supposedly increases microbes and the beneficial bacteria that microbes feed on. If you want to start out with a simple recipe for molasses fertilizer, mix 1-3 tablespoons of molasses into a gallon of water. Water your plants with this concoction and watch them grow bigger and healthier.


MANURE – With a little effort, you’ll find folks that are giving away composted chicken, horse or cow manure for free. Composted and aged manure is best. Add the composted manure to a small permeable bag made from recycled cloth, e.g., a t-shirt or old towel. Let it steep in the shade for a few days and apply it to your soil to condition it before planting. Bury or discard the used bag.

WORM CASTINGS – Make your own worm tea -it’s easy. Start with a handful of red wiggler worms and set them up with some tasty cardboard and kitchen scraps. Learn how. I started about 8 years ago and haven’t stopped since. Check out our video below on composting with worms to see how easy it is to make this amazing fertilizer!

Liquid fertilisers

By Barbara Pleasant

Seedlings don’t need much in the way of nutrients, but if they noticeably darken in color after you feed them with a liquid fertilizer, that’s evidence they had a need that has been satisfied. Liquid fertilizers are also essential to success with container-grown plants, which depend entirely on their growers for moisture and nutrients.

Add the amount of dry ingredients shown in the chart below to a 5-gallon bucket, then add water to fill, and steep for three days. Strain or decant the tea and dilute as shown below. To make fertilizer tea from urine, simply dilute the urine in 20 parts water, and it’s ready to use. Water plants with these solutions no more than once every two weeks.





Following some results of home made fertilisers by the Wood’s End Laboratories:







Nitrogen helps plants grow new stems and leaves. Phosphorus is essential for vigorous rooting, and is usually in good supply in organically enriched soils. Potassium is the “buzz” nutrient that energizes plants’ pumping mechanisms, orchestrating the opening and closing of leaf stomata and regulating water distribution among cells.











It’s important to relieve drought stress before doling out liquid fertilizer. Watering before you fertilize helps protect plants from taking up too many salts.
