Succulents are some of the easiest plants to grow, making them ideal for beginner gardeners and anyone looking to add greenery to their home with minimal effort. What’s even better is that you can nurture these resilient plants using common kitchen scraps—yes, the same peels and leftovers you might usually throw away.
Instead of spending money on expensive fertilizers or additives, you can use nutrient-rich kitchen waste to boost your succulents’ health and growth. With a little know-how, you’ll not only reduce waste but also encourage vibrant, lush succulent displays with minimal cost.
Why Use Kitchen Scraps for Succulents?
Succulents are hardy plants that store water in their leaves and stems. While they don’t need much water or frequent feeding, occasional nutrient boosts can improve leaf color, encourage root growth, and help them recover from stress or repotting.
Most kitchen scraps are loaded with organic nutrients that, when properly prepared, can provide gentle, slow-release nourishment. Unlike synthetic fertilizers, kitchen scraps are natural and less likely to burn or damage the sensitive roots of succulents.
Top Kitchen Scraps to Use for Succulents
Here are some of the most effective scraps you can use to support succulent growth:
1. Banana Peels
Banana peels are rich in potassium and phosphorus—two nutrients that support root development and overall plant vitality. Chop the peel into small pieces and bury them in the soil around the edges of the pot, keeping them away from direct contact with the succulent roots. As the peel decomposes, it slowly releases nutrients into the soil.
2. Eggshells
Eggshells are a fantastic source of calcium, which helps strengthen cell walls and can improve the resilience of your succulents. Rinse and dry the shells, then crush them into a coarse powder. Sprinkle a small amount onto the soil surface or mix into the potting mix during repotting. You can also soak crushed shells in water overnight and use the strained liquid as a mild calcium-rich “tea” for watering.
3. Coffee Grounds (Used and Dried)
Used coffee grounds, when dried and used sparingly, can improve soil texture and provide small amounts of nitrogen. For succulents, it’s essential not to overdo it—excess nitrogen can lead to leggy growth. Mix a pinch of dried grounds into the topsoil or blend into your potting mix when repotting.
4. Vegetable Water
The leftover water from boiling vegetables is full of minerals that succulents can use. Let it cool completely and use it to water your plants once a month. Avoid using salted or seasoned water—only plain, unsalted water is safe for plant use.
5. Rice Water
Water used to rinse or boil rice contains trace nutrients like starches and minerals. Let it cool, then dilute with fresh water (1 part rice water to 3 parts water) and use it to water your succulents occasionally for a mild nutrient boost.
How to Prepare a DIY Kitchen Scrap Fertilizer
If you’d like to create a more balanced fertilizer using scraps, here’s a simple method:
Ingredients:
-
Banana peels (1–2)
-
Eggshells (2–3)
-
Used coffee grounds (1 tablespoon)
-
Water (2 cups)
Instructions:
-
Chop banana peels and eggshells into small pieces.
-
Add everything into a blender with 2 cups of water.
-
Blend until smooth.
-
Let the mixture sit for a few hours.
-
Strain through a cheesecloth or fine sieve.
-
Use the liquid to water your succulents sparingly once a month.
This gentle homemade fertilizer helps encourage root growth, enhances color, and improves plant resilience.
Best Practices for Using Kitchen Scraps with Succulents
To avoid common mistakes and keep your succulents healthy, keep the following tips in mind:
-
Avoid over-fertilizing: Succulents require minimal feeding. Apply kitchen-scrap-based fertilizer no more than once a month during the growing season (spring and summer).
-
Don’t overwater: Succulents are prone to root rot. Only apply liquid fertilizers to dry or slightly moist soil—never saturated soil.
-
Use scraps in moderation: A little goes a long way. Overusing even natural additives can disrupt the soil balance.
-
Compost when possible: If you have extra scraps, compost them first and use the finished compost as a soil amendment.
When to Feed Your Succulents
The best time to feed succulents is during their active growth period—typically spring through early fall. During winter dormancy, most succulents slow down, and feeding should stop to avoid overwhelming their roots.
Conclusion
Growing succulents with kitchen scraps is an eco-friendly, budget-conscious way to care for your plants while reducing food waste. With simple ingredients like banana peels, eggshells, and rice water, you can nourish your succulents naturally and effectively.
Whether you’re a seasoned plant lover or a self-proclaimed “plant killer,” using kitchen scraps gives you a gentle, low-risk way to support succulent growth. Start small, be consistent, and watch your succulents thrive with minimal effort.
