Household Items You Can Use in the Garden

The following tips for frugal gardeners are not only quick, safe, and easy, but also involve using items you probably already have in your house.

ASPIRIN: Dissolve 3/4 of an uncoated aspirin tablet in 1 gallon of water. Spray plants every 2-3 weeks with the mixture to prevent fungus problems, including powdery mildew and black spot. It’s also been found to help some plants yield more fruit than using commercial fertilizers.

BAKING SODA: Mix 1 Tbsp of baking soda and a 1/2 tsp liquid soap into 1 gallon of water. Spray this weekly on plants that are prone to powdery mildew. This works as more of a preventative, as it won’t do much after the powdery mildew has taken hold. Make sure to spray the undersides of leaves. Also, apply it in the evening if you can, as it can burn some leaves.

BEER: Put beer (or water with yeast in it) in a shallow container. Sink the container so that the lip is at ground level in the garden. The beer attracts snails and slugs. They'll fall into it and drown.

BORAX: This is a common laundry additive (20 Mule Team is a popular brand), especially for those of us with hard water. But it also works as a nontoxic ant killer. Ants are a huge problem for us as they “farm” aphids and mealy bugs for their honeydew. We have tons of ladybugs but they are useless if the ants are protecting the pests.

CORNMEAL: Corn Gluten Meal can be used as an effective pre-emergent herbicide, but most of us don’t have that just laying around. Cornmeal, however, is an effective soil fungicide. For every 100 square feet, work 2 pounds of cornmeal into the soil. Water well. One application per season is all that is needed.

DRYER SHEETS: If you’re having a picnic or BBQ and are being plagued by yellow jackets, aka meat bees, and mosquitoes, place dryer sheets around the area to deter them.


EGGSHELLS: Save all of your eggshells! Rinse them and then crush them when they are dry. When preparing a planting bed for tomatoes or peppers add the eggshells (approximately the shells from 1 dozen eggs per plant) to the planting hole to avoid blossom end rot.

EPSOM SALTS: Epsom salts contain sulfur and magnesium and are good for using as a foliar fertilizer. Dissolve 2 Tbsp Epsom Salts in 1 gallon of water. Mist plants as a foliar feeding.

MILK: Dilute milk in a 1:1 ratio with water. Spray your tomato and pepper plants weekly to avoid blossom end rot.

RUBBING ALCOHOL: Apply 70 percent isopropyl alcohol to a cotton ball and apply to scale insects. The alcohol desiccates them. Rub them off when they’re dead so you can continue to monitor their levels.

SHAMPOO: Mix 2-1/2 Tbsp Shampoo and 2-1/2 Tbsp cooking oil with 1 gallon of water. Spray insect pests with the mixture to control them. Do not use in full sun, and a few hours after application, rinse the plant off to reduce injury.

Rachel’s friends in college used to call her a Renaissance woman. She was always doing something crafty, creative, or utilitarian. She still is. Instead of crafts, her focus these days has been farming as much of her urban quarter-acre as humanly possible. Along with her husband, she runs Dog Island Farm, in the San Francisco Bay Area. They raise chickens, goats, rabbits, dogs, cats, and a kid. They’re always keeping busy. If Rachel isn’t out in the yard, she’s in the kitchen making something from scratch. Homemade always tastes better!
