5 Easy Plant Food  Recipes to Feed Your Herb Garden:

First, let’s take a look at what supplies you will need for these various recipes. They are all common household items and ingredients that you probably already have on hand. If not, you won’t need to go further than your local dollar store or grocery store. These ingredients are all safe, inexpensive, easy to find, and easy to use.

Ingredients needed:

  • Epsom Salt
  • Tap water
  • A watering can
  • Used coffee grounds
  • A cookie Sheet
  • Newspaper
  • Eggshells
  • Blender
  • White Vinegar
  • Fish tank water

Now let’s get started! You will want to gather some mixing bowls to mix all of these recipes up as well as labeled spray bottles to store them in if you are not using them right away. Keeping bottles labeled is important so other household members know what they are.

1. Easy Peasy Epsom Salt Fertilizer

Did you know that the common household item Epsom salt is made up of magnesium and sulfate? Plants adore these nutrients.


  • 1 Tablespoon Epsom Salt
  • 1 gallon of tap water
  • A watering can


  1. Mix the Epsom salt and water together
  2. Use the mixture to water your plants at their base.
  3. You can then re-feed once a month.

2. Centsible Coffee Ground Fertilizer
Don’t toss those used coffee grounds. They are packed with plant feeding nutrients! Coffee grounds are rich in nitrogen, magnesium, and potassium!


  • 1 cup of used coffee grounds
  • cookie Sheet
  • Newspaper


  1. Take your newspaper and lay it over your cookie sheet.
  2. Spread your used coffee grounds on the sheet, and allow to dry.
  3. Sprinkle the grounds around the base of your plants.

3. Excellent Egg Shell Fertilizer
Egg shells are packed with calcium carbonate which soil loves. Just save your breakfast shells and allow them to work their magic.


  • 3-5 Egg Shells
  • A blender


  1. Rinse your used egg shells and then allow them to air dry.
  2. Then, place the dried shells in the blender.
  3. Pulse until they fine.
  4. Sprinkle into your soil and cover well.

 4. Very Simple Vinegar Fertilizer
This is one of the easiest DIY plant foods you can try. All it takes is two ingredients you can find in any kitchen. It costs just pennies and the soil will just devour it, creating a healthy base for your plants.


  • 1 tablespoon white vinegar
  • 1 gallon of tap water
  • watering can


  1. Simply combine the white vinegar and water in a dish.
  2. Mix well. Add to a spray bottle or watering can.
  3. Use the solution to water your plants and repeat every three months.

5. Frugal Fish Tank Water Fertilizer
This plant food is a favorite because it lets you reuse something that would otherwise be getting poured down the drain. Fish water is full of nitrogen and is perfect to feed your plants.


  • Used fish tank water…that is easy, huh?


  1. All you need to do is retain the water when you clean your fish tank.
  2. Pour it into the base of your plants, directly into the soil.
  3. If you don’t have a fish, you can always ask a friend or family member who does to retain theirs for you in a gallon jug.

Making your own plant food for your herb garden has never been easier or cost less. You will wonder why people pay big bucks for it at the store when natural and inexpensive options such as these are right under their noses. Well now you know better, and can start saving money and trips to the store when it comes to feeding your herb garden!

  1. This is awesome! I’ve been dying to plant a garden, but the Arizona soil in my backyard just won’t take it. One day! Bookmarking this post for later!

  2. What great tips! We tried a little herb garden a couple of years ago and it actually did well (to our surprise :-)), but then life got busy and we didn’t keep it going. But your instructions seem so easy, it’s making me want to try again. It’s so nice to walk into the backyard and see the fruits of your labor blossoming!

  3. Great tips! I’ll pass them along to the gardeners in my life 😀

  4. Thanks so much for sharing this! I am always looking for inexpensive ways to improve my gardening! Thanks so much for linking your post to the garden linky this week!

  5. Great tips! I hope to start my own little garden whenever we purchase our own home. I’ll have to pin this for future reference!

  6. We love using coffee grounds in the garden but I never thought to add the fish water! Such a great idea.

  7. These are great tips, thanks so much! I just moved into a house with some raised garden beds and we are excited to grow our own veggies this year.

  8. This is great – for some reason I never have any success with herbs! The vegetables and fruit always do well, but the herbs die a miserable death!

  9. I am always up for anything like this. Growing a garden SHOULD be easy (and frugal!) I’m pinning this so I can look back at it this week. I’m sure my husband will want to try it on our garden when we get a day with sunshine again. :)
