So, the next time you are left with an entire bowl of pistachio shells, don’t toss them away in the bin. Gently wash the shells with water and allow them to dry completely before you do anything with them.
Surprising Uses of Pistachio Shells in Your Garden and Home

Both salted and unsalted shells offer a myriad of interesting and surprising uses.

Drainage Pebbles for Potted Plants
When it comes to potting drainage, the regular material that is used includes pebbles and small rocks. But, as it turns out, pistachio shells are a much better option and offer greater benefits than the former. Their biggest advantage is that they eventually biodegrade. This simply means that you won’t have to take them out of the soil when you re-pot your plants. Moreover, they also keep the root system super healthy by draining excess moisture.
Using pistachio shells at the base of potted plants as drainage pebbles will successfully prevent the plants from becoming waterlogged. These shells are particularly useful when the plant pot doesn’t have a proper hole for drainage.
If you have an empty pot, add about an inch-thick layer of the shells neatly across the bottom. Then, throw in the soil and add your plants.
If your garden is suffering from pests, you can easily keep them away with the help of pistachio shells!
Snails and slugs are two of the most common pesky pests that attack potted plants in the garden. Moreover, you might even find raccoons, squirrels, and chipmunks digging the soil in your garden.
Pistachio shells help make a garden and potted plants less appealing to these pests, thereby ensuring effective pest control.
Cover the soil in your garden by spreading pistachio shells as a thick top dressing all over it. This will successfully prevent animals like squirrels, raccoons, cats, etc., from digging in the soil. To keep slugs and snails away, make sure that your pistachio shells are salted. Simply sprinkle the shells around the perimeter of your garden or in a neat line around every individual plant.
Organic, Durable Mulch
From reducing weed growth to improving soil fertility to boosting the visual appeal of the soil, mulch offers a variety of benefits.
Mulch is a layer of materials like decaying leaves, bark, and compost applied to the surface of the soil.
Pistachio shells serve as a highly beneficial mulching material for the soil in your garden. They break down with time and gradually release protein, carbon, fats, and carbohydrate that will help feed the soil.
When mixed with wood chips, leaves, and bark, the shells make durable organic mulch that restrains weed growth, keeps the soil moist, and enhances its fertility. You can also use the shells alone and apply a layer on the surface of the soil.
The right way to use pistachio shells for mulch is to soak them in water overnight. Then, you can take them out of the water and sprinkle them over the soil in your garden.

What makes these shells ideal for starting fires is their hard, dry texture and the oil content in the shells.

Pistachio shells are as effective when used as compost, as they are when used for mulching.
They make excellent compost material given their great water retention abilities.
Note that the shells take quite a long time to degrade, given their hard texture. However, you can boost the process by crushing them up before you add them to the soil. Another thing you can do is soak them in water overnight to soften the shells. Then, the following day, add them to the soil along with the water.
There’s no denying the fact that pistachio shells have many incredible and unique uses not only in the garden but also in DIY home projects.
