Effects of Expired Medicine on Plants

There are many amazing plant hacks available on the internet that can boost your plant growth–One of them is using expired medicines that generally go in the trash box after their expiry date.

In research on the use of expired multivitamins, it has been found that expired vitamins and calcium supplements, in moderate amounts, can be used in the garden in the form of manure, or you can dilute them in water to feed your plants.

  • Vitamin B1: Stimulates root and flower growth
  • Calcium: Results in a healthier root system
  • Vitamin B12: Results in healthy leaves
  • Zinc Sulphate Monohydrate: Helps in the synthesis of certain proteins that aids in the formation of chlorophyll
  • Vitamin C: Regulates cell division and growth
  • Folic Acid: Green and fuller foliage
  • Vitamin B2: Regulates drought tolerance in plants
  • Nicotinamide: Helps in the overall growth of the plant
  • Vitamin D3: Enhances and speeds up the root formation

Uses of Expired Medicine and Vitamins for Plant Growth

1. Feed Plants with Expired MultiVitamins

Instead of throwing away expired multivitamin capsules, add them to your plant fertilizer. Supplements composed of calcium eliminates stunted growth in plants and helps in forming new leaves and tissues. If your plants show weak and lanky growth, adding a few zinc tablets in the water will greatly help the plants in the conversion of starch to sugar.

2. Expired Medicines in Compost

You can throw some expired medicines in your compost pile. Multivitamins can be added to compost along with folic acid and Vitamin C. They raise seed vigor and offer potential seedling production.

3. Water your Plants with Expired Vitamins

Dissolve some expired multivitamins in distilled water and water your plants once a month this way. Vitamin B12 is a great addition to green vegetables like spinach and fruits, improving nutrition uptake in plants. Since plant roots can actively absorb Vitamin B12, you can mix the tablets in water.

Supplements You Can Use in the Garden

Expired supplements do not become toxic or lose their potency when it comes to their use in plants. If you have bought whey or soy protein in large quantities and some leftover got expired, don’t worry! You can use it in the following ways:

  • Soy (Glycine max) protein contains protein, fiber, iron, phosphorus, copper, and manganese. You can use expired soy supplements in the garden by diluting it one scoop per gallon of water.
  • As whey is rich in milk solids, it can aid in plant growth by providing several essential nutrients like nitrogen, phosphorus, potassium, calcium, and magnesium. Dilute one scoop per 2 gallons of water and feed your plants.
  • Whey is also acidic to some extent and is super beneficial for acid-loving plants like azalea and gardenia. It can also help in correcting the soil pH!

Aspirin Tablets in the Garden

Whether expired or not, aspirin tablets can do wonders for your plants; you can use them to combat fungal diseases, and they work as rooting hormone as well. Its addition also increases immunity against pests and diseases in plants. If you want to learn more about aspirin use in the garden, read this article here.
