Can I put juicer pulp in my garden?

Juicing fruits and vegetables is a great way to get an extra serving of nutrients into your diet. But what should you do with all that leftover pulp? Many juicers wonder if it’s okay to deposit the wet pulp directly into their yard or garden. Let’s take a look at the pros and cons of using juicer pulp in your outdoor spaces.

Benefits of Putting Juicer Pulp in the Garden

There are some potential benefits to using juicer pulp in your garden:

  • It can add organic matter and nutrients to the soil
  • May help retain moisture in the soil
  • Provides a free, natural fertilizer
  • Keeps pulp out of landfills/reduces food waste
  • Saves time and money on disposing of pulp

Juicer pulp is mostly made up of fruit and vegetable skins, seeds, and fibrous parts. All of these components contain valuable nutrients that plants need like nitrogen, phosphorus, potassium, and magnesium. And as the pulp breaks down, it can improve soil structure and water retention.

Here’s a look at some of the nutrients commonly found in juicer pulp from popular juicing ingredients:

Ingredient Key Nutrients
Apples Calcium, iron
Carrots Vitamin A, potassium
Kale Vitamin K, calcium
Celery Vitamin K, magnesium
Ginger Iron, magnesium, phosphorus
Beets Folate, manganese, potassium

As you can see, juicer pulp contains a variety of plant-based nutrients that make it a free, natural fertilizer or compost booster for your garden. Utilizing the pulp keeps it out of landfills and prevents food waste.

Potential Drawbacks of Juicer Pulp in the Garden

However, there are also some potential downsides to watch out for when using juicer pulp in your yard or garden:

  • Can create messy, slippery layer when fresh
  • May attract pests like flies, rodents, or animals
  • High in sugars and acids – could potentially alter soil pH
  • Risk of transferring diseases from raw produce
  • Contains high moisture – can encourage mold if not dried out

Fresh wet juicer pulp can be quite slimy and slippery, which can make a mess if you deposit large amounts right into your garden. The pulp will be very high in sugars and organic acids from the fruits and vegetables, which can temporarily lower soil pH.

It’s also possible to transfer any diseases or pathogens from the original produce into your garden this way. And with all of its moisture, untreated wet pulp can get moldy quickly in a pile.

Best Practices for Using Juicer Pulp Outside

If you want to use juicer pulp to benefit your garden, there are some best practices to follow:

Dry it Out First

To avoid issues with mess, mold, and pests, it’s best to dry the wet pulp out first before adding it to your garden. Here are a few options:

  • Spread onto sheets and let air dry for 12-24 hours.
  • Use a food dehydrator to dry pulp into chips.
  • Bake pulp on parchment paper at 170°F until dried out.

Mix With Other Materials

For best results, mix dried juicer pulp with other amendments before adding to your garden. This helps balance out the nutrients and acids. Good options include:

  • Compost
  • Peat moss or coco coir
  • Shredded leaves
  • Manure
  • Dry grass clippings

Mix 1 part dried pulp with 2-3 parts of your choice of amendments. Make sure the resulting mixture is not soggy or wet.

Scatter and Till Into Soil

Scatter thin layers of your pulp mixture over garden beds and borders. Then till lightly into the top 2-4 inches of soil, being careful not to disturb plant roots if already planted.

This will help incorporate the nutrients down into the soil where plant roots can access them. Spreading thin layers will prevent matted clumps.

Use Around Acid-Loving Plants

The acidic nature of juicer pulp makes it especially beneficial for acid-loving plants. Sprinkle blended and dried pulp around:

  • Blueberries
  • Azaleas
  • Hydrangeas
  • Rhododendrons
  • Ferns
  • Evergreens

The pulp will help lower soil pH and provide nutrients that these types of plants thrive on.

Can You Add Juicer Pulp Directly to Your Garden?

While it’s not recommended, you can attempt to utilize fresh wet juicer pulp directly in your garden. Here are some tips to give it the best chance of success:

  • Spread into very thin layers – no more than 1-inch deep piles.
  • Mix thoroughly into soil – don’t leave clumps sitting on top.
  • Water gently after adding to activate decomposition.
  • Cover with mulch or leaves to contain mess and odor.
  • Monitor for mold growth and remove any you spot.
  • Only use pulp from fresh, disease-free produce.

Adding fresh pulp directly comes with risks as mentioned previously. But during the growing season, your garden soil should contain enough bacteria, fungi, and other decomposers to break the pulp down relatively quickly without issue.


While juicer pulp has great potential as a nutritious, organic addition to your garden, there are some precautions to take. Allowing fresh pulp to dry first, then mixing with compost or other amendments is ideal. Scatter thin layers over beds and borders and till in gently. With the right process, you can keep pounds of juicer pulp out of landfills and turn it into free “fertilizer” instead. Your plants will reap all the nutritional benefits of your favorite fruits and veggies. Just be sure to monitor for any issues like pests or odor during the decomposition process.

Pros Potential Cons
  • Adds nutrients to soil
  • Improves moisture retention
  • Free fertilizer source
  • Reduces food waste
  • Can create mess when fresh
  • May attract pests
  • Could alter soil pH
  • Risk of transferring diseases

Following best practices like drying, mixing, and tilling pulp into your beds minimizes any risks. With the proper preparation, juicer pulp can be a beneficial addition to most gardens.
