Eco-Friendly DIY Fertilizers

Try these easy, green alternatives to chemical fertilizers that will nourish your garden



Feed your garden with one of these six earth-friendly options.

Coffee Grounds

Coffee grounds are a thrifty source of nitrogen as well as smaller percentages of potassium and phosphorus (in that order). And the best part...slugs hate coffee. Sprinkle some around their favorite plants to keep those slimeballs away.

The trouble with coffee is that it is slightly acidic. Adding a sprinkle straight onto the soil around most edible crops is generally okay now and again, but heavy coffee drinkers should save direct application for acid-loving plants like blueberries. Better yet, compost large quantities first and it will be ready to use all over the garden without burning sensitive plants and seedlings.

Crustacean Shells (shrimp, crab, lobster)

Chop up the inedible shells from tonight's dinner and drop them into a 2-foot hole dug in the garden. The shells will compost in a matter of weeks, adding nitrogen, phosphorus, and lime (alkaline) to the soil on site. Mark the spot and dig up the compost in a month or so if you want to spread the goodness around.

Poultry Manure

It smells awful, but chickens make excellent, super-nutrient-rich fertilizer as they soil their bedding. If you're keeping your own chickens, you can't let all of that good stuff go to waste. Put it in the compost bin, bedding and all, for at least 6 months first, because fresh manure is super high in nitrogen and can burn plants.

Comfrey Tea

Comfrey (Symphytum officinale) is a doggedly invasive plant that also happens to be chockablock full of phosphorus, potassium, magnesium, and trace minerals and vitamins. You can benefit from its persistence in the garden by turning it into a rich fertilizer tea and feeding all that goodness to the plants that need it. Brew up a batch by mixing 1 part comfrey leaves in a bucket with 2 parts water. Set it in the sun for a day or two to brew, then strain it. Compost the remaining parts and use the liquid as a fertilizer. Dilute it down with water by half or more to use as a foliar spray.

Fish Scraps

Deeply bury uncooked fish heads, guts, and tails in the garden bed where they will break down into the soil, providing lots of nitrogen, trace minerals, and a bit of calcium. Dig holes about 2 feet deep to keep curious critters from nosing around. If you grow in rows, try burying fish parts in between the rows or near nitrogen-loving plants like tomatoes and corn.

Worm Poo Tea

Vermicompost is a great, well-balanced addition to the garden and even better when applied as a liquid foliar feed. If you're keeping a worm bin, there's no reason to buy the store-bought stuff! Steep a couple of tablespoons of worm casting, straight out of the bin, in 4 liters of warm water for about 24 hours and strain it into a spray bottle. If you like, you can even prepackage the castings in paper or muslin filters.

This article shares a lot of good information. I really do believe that these organic fertilizers are much better to use than those chemically made fertilizers. Those people who are using some of those listed above can save money than buying sacks of those chemically made fertilizers. That is why, I really suggest to my friends to choose organic over chemical made fertilizers. -www.chemwisenutrients.com

Making your own organic plant food is easy and fun. It should be noted that most people understand that the best way to get good garden soil is to use compost to amend the soil. Of course, that is true. Compost can be made at home out of leftover food scraps and lawn clippings, and so it is virtually cost-free.
