Recycling Juicer Pulp: A Guide to Using it as Compost in Your Garden

Transform Your Leftover Juicing Pulp into Nutrient-rich Plant Food

Can I Put Juicer Pulp in My Garden?

If you regularly make fruit and vegetable juices at home, you know they generate a lot of pulp as a byproduct. This fibrous pulp is left over after the juicing process extracts all the liquid goodness from your fresh produce. Rather than throwing all that juice pulp in the trash, you may be wondering - can I put juicer pulp in my garden?

The answer is a resounding yes! Not only can you add juice pulp to your garden, but it makes an excellent addition to compost as well. Juicer pulp provides several benefits when used in the garden, such as enriching soil with nutrients like nitrogen, phosphorus, and potassium. It also contains insoluble fiber that improves soil structure and moisture retention.

In this article, we’ll explore the benefits of repurposing your veggie and fruit pulp in the garden and compost pile. You’ll also learn what types of produce pulp work best, along with application tips.


Why Use Juicer Pulp for your garden?

Rather than wasting all the pulp your juicer spits out, you can repurpose it in the garden and compost pile to provide a variety of advantages:

It’s a Nutrient Gold Mine

Fruit and vegetable pulp is teeming with valuable macro and micronutrients that plants thrive on. When you juice fresh produce, the process removes most of the easily digestible sugars, fluids, and vitamins. But much of the insoluble fiber, pulp, skins, seeds, and flesh stay behind in the leftover material.

And this pulp still contains a wealth of key nutrients, including:

  • Nitrogen - critical for plant growth and development. Needed for green/leafy growth.

  • Phosphorus - supports root, flower, fruit, and seed production. Boosts blooms.

  • Potassium - is crucial for water regulation, nutrient transport, and disease resistance in plants.

  • Calcium - strengthens cell walls. Helps fruit/veggie quality and resistance.

  • Magnesium - is central to plant enzyme reactions and photosynthesis. Aids vital chlorophyll.

  • Iron - helps form crucial proteins and enzymes. Prevents leaf yellowing.

  • Zinc - is involved in plant sugar and carbohydrate production. Boosts yields.

  • Copper - aids in enzyme reactions. Needed for healthy roots and reproduction.

Recycling all these minerals and micronutrients back into your garden or compost nourishes your plants and soil life in a natural, organic way.

It Provides Essential Fiber

In addition to nutrients, the insoluble fiber left in juice pulp brings valuable organic matter to your garden soil. The cellulose and pectin fibers in fruit/veggie pulp serve as fuel and food for soil microorganisms and worms.

As these tiny helpers break down and consume the pulp fiber, they support improved soil structure. Their tunnels and excretions make the soil less compact and allow better water infiltration, drainage, and aeration. This facilitates healthier root growth and function for plants.

The spongy fiber strands also help soil retain more moisture and nutrients essential for plant health. This can reduce watering needs in garden beds amended with pulp.

It’s Ideal Compost Material

The nutrients, fiber, sugars, and moisture content of fresh juice pulp make it a perfect “green” addition to backyard compost piles. Adding pulp helps provide balance with carbon-rich “brown” materials like dried leaves, straw, sawdust, or wood chips.

The pulp contributes an optimal blend of carbon and nitrogen that compost microbes thrive on. It also offers natural sugars, carbs, and cellulose these organisms use for energy to break down waste and reproduce.

As a result, including juice pulp in compost can significantly accelerate the decomposition process. It boosts the nutrient content of the finished compost you spread back onto your garden beds.

It's Free Fertilizer

Since juice pulp is simply a leftover byproduct of home juicing, it's essentially free fertilizer and compost material. Rather than wasting the nutritious pulp, you can recycle it back into garden soil or compost. This saves you money on purchasing commercial fertilizers, compost, or other soil amendments.

And unlike store-bought chemical fertilizers, juice pulp nourishes your soil and plants in an entirely natural, organic way. It helps support the web of microbial life that forms the living foundation of healthy, productive garden soil.

It Reduces Food Waste

Repurposing juice pulp for your garden also means significantly less food waste from your juicing habits. Food waste is a massive problem in the United States, with estimates of 30-40% of all food produced ending up in landfills.

But recycling pulp into your yard and compost allows this nutrient-rich material to re-enter the food cycle, rather than rotting away in a garbage dump. So your garden benefits, while food waste is reduced.


What Juice Pulps Are Best for Compost?

Can I Put Juicer Pulp in My Garden?

While juice pulp from most fruits and vegetables can go into compost piles, some types provide greater benefits than others:

Vegetable Pulp

Leafy green veggie pulp is fantastic for boosting compost nutrition. Pulped spinach, kale, lettuce, chard, beet greens, and fresh herbs are loaded with nitrogen, chlorophyll, and valuable minerals that nourish compost life.

Other great vegetable pulp for compost includes:

  • Tomatoes - Contain nitrogen and potassium. Provide needed moisture.

  • Peppers - Have calcium, vitamin C, and antioxidants.

  • Broccoli/Cauliflower - Offer phosphorus, magnesium, and sulfur.

  • Celery - Contains organic sodium beneficial to compost.

  • Cucumbers - Have potassium, magnesium, and silica.

Fruit Pulp

Citrus fruit pulp like orange, grapefruit, lemon, and lime gives an acidic pH bump to compost. This helps decompose materials like bone, meat, and dairy. Citrus fruits also contain ample nitrogen.

Berry pulp from strawberries, blueberries, raspberries, etc. introduces antioxidants and micronutrients often lacking in compost. Their seeds benefit microorganisms as well.

Other great fruits for compost pulp include:

  • Apples - Offer potassium, phosphorus, and pectin fiber.

  • Grapes - Contain potassium, iron, and silica.

  • Pineapple - Has manganese, vitamin C, and bromelain enzymes.

  • Melons - Provide hydration; high in electrolytes.

  • Kiwi - Impart vitamin C, potassium, and phytonutrients.

Avoid Too Much Starchy Pulp

Some vegetable and fruit pulp is higher in starches, sugars, and wetness, like potatoes, bananas, and winter squashes. Too much of these pulps can compact a compost pile and restrict airflow if not properly balanced out with absorbent, dry materials. Use them in moderation.


How Should I Add Juicer Pulp to My Garden/Compost?

It’s super simple to start utilizing juice pulp for your garden beds or compost bins.

Here are some application tips:

For Garden Beds:

  • Bury pulp 2-4 inches below the soil surface around plants. This prevents drying out while delivering nutrients as it break down.

  • When preparing new garden beds, mix pulp into the top 6 inches of soil. Blend with aged compost or manure for added nutrition.

  • Place a thin layer of pulp around plant bases, gently working into the top inch or two of soil. Water well to aid decomposition.

  • Limit high-acid fruit pulp (citrus, berries) to a once-monthly application to avoid substantially altering soil pH. Vegetable pulp can be used more often.

  • Rotate pulp applications through different parts of garden beds over time. Don't overload any one area.

For Compost Piles:

  • Add pulp as a “green” nitrogen source, balancing with “browns” like dried leaves, straw, sawdust, or wood chips. Shoot for a 30:1 carbon-to-nitrogen ratio.

  • Bury pulp in a compost pile at least 8-12 inches deep, not just on top or edges. Prevents odors, flies, and animals.

  • If adding a large amount of pulp, include some finished compost or garden soil. This introduces decomposers to accelerate breaking it down.

  • Turn and mix compost well after adding pulp to distribute evenly and prevent clumping or matting.

  • Limit higher acid pulp like citrus or berries to 25% or less of total compost volume so pH stays in optimal range.



As you can see, recycling the abundant pulp from homemade juices is a fantastic way to nourish your garden beds and compost pile. The pulp left over from juicing provides a free and readily available source of key nutrients, organic matter, and compost material.

Rather than letting nutritious juice pulp go to waste, put it to use in your home garden. Bury and mix it into soil or add it as “green” matter to your compost. This simple practice reduces food waste while supporting the health of your plants and soil.

So go ahead and add that juicer pulp to your garden beds and compost piles.
