Plants need three things to survive and thrive: Potassium, Phosphorus, and Nitrogen. While store bought chemical fertilizers typically have these nutrients, you can also provide them to your plants without the harsh chemicals by just making them yourself, and most of them can be made with things that you already have on hand, and will probably just throw out.
1. Coffee Grounds Fertilizer
Let’s start with coffee because well, you really need coffee, right? Most of us have coffee grounds leftover every day…I know I do. So, you’ll use those grounds, which by the way are filled with nitrogen and helps to increase the acidity in the soil. This is an especially good fertilizer for roses, hydrangeas, and magnolias, but you can also use it on your veggies to help them grow. This is also a really simple recipe – it just takes coffee grounds. You just work your grounds into the soil at the base of your plants, and the coffee will perk those plants right up!
2. Straight Epsom Salt Fertilizer
If you prefer something a bit more simple, you can mix Epsom salt with water for a good fertilizer, too. You can find Epsom salt on amazon and it’s really inexpensive. It’s also a great source of magnesium and sulfur and is especially good for roses and tomatoes. This is a no-fail fertilizer. You just can’t get this one wrong. Just add a tablespoon of salt to a gallon of water and use this to feed your indoor and outdoor plants.
3. Banana Peel Fertilizer
Okay, so you’ve probably heard of using banana peels to help plants grow, right? We all know that bananas are rich in potassium. They also contain calcium and phosphorous and are perfect for fertilizing flowering plants and fruit trees and plants. You can just bury banana peels in the soil at the base of your plants and allow them to decompose. You could also freeze your overripe bananas (if you aren’t planning to make banana nut bread, that is) and then bury those next to your plants. Or, make a spray by soaking banana peels in water for three days and then spray your plants or seedlings to add the needed nutrients. This is also a great recipe for houseplants.
4. Egg Shell Fertilizer
Egg shells are something else that you probably have tons of throughout the week and typically just throw out. The shells contain a lot of calcium which helps with cellular growth in your plants. Calcium deficient soil can lead to blossom end rot on tomatoes and various other garden catastrophes. This egg shell fertilizer will help to end that. Just crush up used egg shells and then bury them in the soil. Or, you can make a spray with 20 egg shells and a gallon of water. Boil the shells in the water for just a few minutes and then leave overnight. Strain the shells and add the water to a spray bottle to spray directly onto your soil.
5. Vinegar Fertilizer
Vinegar has acetic acid that is great for certain plaints. You can use this on roses and various other houseplants as well as vegetables in your garden. To make vinegar fertilizer, just combine a tablespoon of white vinegar (only white vinegar as apple cider vinegar doesn’t have the same nutrient properties) mix with a gallon of water. Use this solution to water your plants about once every three months for best results.
