Geraniums are well-loved flowering plants that thrive in containers, hanging baskets, and garden beds. Their vibrant blooms and fragrant foliage make them a favorite among both beginner and experienced gardeners. What makes them even more appealing is how easy they are to grow and maintain — especially when you incorporate nutrient-rich kitchen scraps into your care routine.
If you’re looking to cultivate geraniums without spending on expensive fertilizers or additives, your kitchen waste may hold the key. From coffee grounds to banana peels, certain scraps can provide essential nutrients to help your geraniums thrive. Here’s how to get started.
Why Grow Geraniums?
Geraniums (Pelargonium spp.) are known for their bright, colorful blooms and their tolerance for a variety of growing conditions. They flourish in both containers and garden soil, making them versatile for balconies, windowsills, or backyard borders. Aside from their ornamental value, geraniums are also natural pest repellents and can enhance the health of your garden environment.
Step 1: Choose the Right Variety and Location
There are many types of geraniums, but the most popular include:
-
Zonal geraniums – Upright and robust, perfect for pots and garden beds.
-
Ivy-leaf geraniums – Trailing, ideal for hanging baskets.
-
Scented-leaf geraniums – Grown mainly for their fragrant leaves.
Choose a sunny location for your geraniums. They prefer 6 to 8 hours of sunlight daily and well-draining soil. If you’re planting in containers, make sure they have drainage holes to prevent root rot.
Step 2: Propagate from Cuttings or Use Nursery Plants
You can start geraniums from seed, but cuttings are the easiest and quickest way to grow new plants. Here’s how:
-
Take a healthy 4- to 6-inch cutting from a mature plant.
-
Remove the lower leaves, leaving only a couple at the top.
-
Allow the cutting to sit for a few hours so the cut end can callous over.
-
Plant the cutting in moist potting mix, preferably with a bit of perlite for drainage.
-
Place in indirect light until roots form (usually within 2–3 weeks).
Once the cutting is rooted, it can be moved to a sunnier spot or planted directly into its final container or bed.
Step 3: Use Kitchen Scraps to Feed Your Geranium
Many kitchen scraps contain the nutrients geraniums need for healthy growth and flowering. Here are some of the best scraps to use and how to apply them:
1. Banana Peels
Rich in potassium and phosphorus, banana peels help boost flowering. Chop them finely and bury around the plant base. They break down quickly and enrich the soil.
2. Coffee Grounds
Used coffee grounds provide nitrogen and improve soil texture. Let them dry out before adding to the soil to avoid mold. Use in moderation—about a tablespoon per plant every couple of weeks.
3. Eggshells
Crushed eggshells add calcium, strengthening the cell walls of your plants. Rinse and dry them before crushing into small pieces. Mix into the soil around your geraniums.
4. Vegetable Peels
Composted vegetable scraps such as carrot and potato peels can enrich the soil. Avoid using raw peels directly as they can attract pests—compost them first or bury them deep into the soil where they can decompose slowly.
Step 4: Create a Simple Homemade Fertilizer
For a nutrient boost, make a liquid fertilizer using your kitchen waste:
-
Fill a jar or bucket with banana peels, coffee grounds, eggshells, and water.
-
Let the mixture steep for 3–5 days.
-
Strain the liquid and use it to water your geraniums once every two weeks.
This homemade “tea” provides a slow, natural feed that encourages lush growth and vibrant blooms.
Step 5: Regular Maintenance
To get the best results, pair your natural fertilization with basic geranium care:
-
Deadhead spent flowers regularly to promote continuous blooming.
-
Water when the top inch of soil is dry, avoiding soggy soil.
-
Prune leggy stems to encourage bushier growth.
-
Protect from pests like aphids and spider mites with neem oil or soapy water.
If growing in containers, refresh the soil annually and trim roots if they become pot-bound.
Step 6: Overwintering Tips
In colder climates, geraniums can be overwintered indoors:
-
Dig up garden plants before the first frost.
-
Cut back the foliage by half and transplant into pots.
-
Place in a sunny window and water sparingly through winter.
-
Reintroduce to the garden in spring after the last frost.
This allows you to keep your plants year after year without buying new ones.
Conclusion
Geraniums are one of the most rewarding plants to grow, and with the help of common kitchen scraps, you can nurture them easily and sustainably. Banana peels, eggshells, and coffee grounds not only reduce waste but also provide the nutrients your plants need to bloom more abundantly.
Whether you’re growing them in containers or garden beds, this low-cost, low-effort method helps you enjoy healthier, more vibrant geraniums throughout the growing season.
