Growing Healthy Geraniums: Tips and Care Guide
Geraniums are some of the most popular and beloved plants worldwide. Known for their vibrant flowers, ease of care, and ability to bloom year-round, it’s no wonder they’re found in gardens everywhere.
While many people refer to them simply as “geraniums,” the plants we commonly grow are actually pelargoniums, specifically Pelargonium x hortorum. These beautiful plants come in a variety of colors and are often seen on balconies or in window boxes. Let’s dive into how you can take care of these vibrant plants so they thrive and bloom all year long.
1. Provide Enough Light and Sun
Geraniums love the sun! They thrive best with about 4-6 hours of full sunlight each day. If possible, give them full sun in the morning and then provide light shade in the afternoon to prevent them from getting too much sun exposure, especially on hot days.
These plants also love being in open, well-ventilated spaces, so make sure they aren’t too crowded or tucked in a corner where air flow is restricted.
2. Avoid Overwatering
While geraniums don’t like dry soil for long, overwatering is one of the most common mistakes gardeners make. They can tolerate periods of dry soil much better than they can handle sitting in waterlogged soil.
How to tell if you’re overwatering? Yellowing leaves are a sign, and it’s usually due to either too much or too little water.
Geraniums prefer humid but well-draining soil, so make sure your pot has drainage holes to allow excess water to escape. Water them only when the soil feels dry. If you find it tricky to gauge the moisture, consider using a moisture meter to make things easier.
3. Feed Geraniums with Fertilizer
Although geraniums planted in nutrient-rich soil don’t require frequent feeding, fertilizing them occasionally will encourage better blooms and healthier growth. During spring and summer, feed them once every 4-6 weeks. In the fall and winter, reduce fertilization to once every 8 weeks.
You can purchase a water-soluble fertilizer, or if you want a homemade option, try this simple DIY recipe:
- 1 gallon of water
- 100g of fresh yeast
- 1/2 cup of sugar
Mix the yeast in warm water, add sugar, cover with a kitchen towel, and let it ferment. Once fermented, dilute the solution with 10 liters of water and use it to water your geraniums every 10 days during the growing season.
4. Deadhead and Remove Yellow Leaves
Deadheading is a must! Once your geranium’s blooms start to turn brown, trim off the spent flowers from the bottom of the stems. Doing this not only improves the plant’s appearance but also allows it to direct its energy toward new blooms.
Don’t forget to remove yellow leaves as well, especially those at the bottom. Yellowing leaves can be caused by various factors like lack of light, over-watering, or even disease. Keeping your plant tidy helps prevent the spread of any potential issues.
5. Protect Geraniums from Pests
While geraniums are generally pest-resistant, they can still fall victim to aphids, caterpillars, and whiteflies. Here’s how to handle them:
- Caterpillars: The easiest way to deal with caterpillars is to hand-pick them from your plants. If you’re not a fan of that, you can use a pesticide containing Bacillus thuringiensis, a natural bacteria that’s safe for pets and humans.
- Aphids and Whiteflies: For aphids, mix 1 gallon of water with 1 tablespoon of organic soap. Spray the solution on your plants when you spot aphids, and it should help eliminate them.
6. Pinch Back for a Bushier Plant
To make your geraniums grow bushier rather than just tall and leggy, you can pinch them. This simply means cutting off the tops of the plants when they’re young. This encourages the plant to grow side shoots, creating a fuller, more compact look.
Conclusion
Geraniums are easy to care for, but knowing their needs is key to growing healthy, vibrant plants that produce gorgeous blooms all year round. By providing them with enough sunlight, watering correctly, fertilizing occasionally, deadheading regularly, and protecting them from pests, you’ll be well on your way to enjoying a beautiful garden full of colorful geraniums. Happy gardening!

Q3: Can geraniums tolerate cold weather?
👉 Geraniums are sensitive to frost. If you live in a region with cold winters, bring your plants indoors or cover them during frosty nights.
Q4: How can I make my geraniums bloom more?
👉 Regular deadheading, ensuring the plant gets enough light, and providing appropriate fertilizer will encourage more blooms.
Q5: Why are my geranium leaves turning yellow?
👉 Yellowing leaves are usually a sign of overwatering or nutrient deficiencies. Check the watering schedule and consider feeding them with a balanced fertilizer.
