Many plants, including evergreens, prefer growing in acidic soil. Rich earth constantly fed by falling leaves, pine needles and other material is naturally acidic. If the soil you are using is not, a few homemade fertilizers can improve it. The supplies needed can be found in your home or at a local garden center.
Pour a couple of tablespoons of white vinegar in a spray bottle.
Fill the bottle with water and put the lid on.
Shake the bottle to mix the two ingredients together.
Spray your plants with a light mist of the fertilizer.
Using Coffee Grounds
Pour old coffee grounds on a baking pan.
Place the pan in the oven on low heat for 10 minutes or so. You just want them to dry out.
Take the pan out of the oven and let the grounds cool.
Sprinkle the coffee grounds around plants that prefer acidic fertilizer.
