Geraniums (Pelargoniums) are beloved for their beautiful flowers and easy care, but they can be quite sensitive to certain things. Here are the 10 most common mistakes that can weaken or even kill your geraniums — and how to avoid them for healthy, long-blooming plants.
1. Overwatering
Geraniums hate “wet feet”. Too much water leads to root rot and yellow leaves. Solution: Water only when the top 2–3 cm of soil is dry. Always ensure good drainage.
2. Poor Drainage
Water that stays stagnant in the pot is deadly for geraniums. Solution: Always use pots with drainage holes and add perlite or gravel at the bottom.
3. Lack of Sunlight
These plants love light. Without enough sun, they become leggy and produce few flowers. Solution: Place them in a spot with at least 6–8 hours of direct sunlight per day.
4. Cold Drafts and Low Temperatures
Geraniums are sensitive to cold. Temperatures below 10°C can damage them. Solution: Protect them from cold drafts, especially in winter. Ideal temperature is 15–24°C.
5. Over-Fertilizing with Nitrogen
Too much nitrogen makes them grow lots of leaves but very few flowers. Solution: Use a balanced fertilizer or one rich in potassium and phosphorus during flowering.
6. Planting Too Deep
Burying the stem too deep encourages rot. Solution: Plant so the crown (where stem meets roots) stays at soil level.
7. High Humidity Without Airflow
Constant high humidity without ventilation promotes fungal diseases. Solution: Ensure good air circulation around the plants.
8. Using Dirty Tools or Pots
Old soil or dirty pots can spread diseases. Solution: Always clean pots and tools before use.
9. Leaving Faded Flowers
Not removing dead flowers wastes the plant’s energy. Solution: Deadhead regularly to stimulate new blooms.
10. Sudden Temperature Changes
Big swings in temperature stress the plant. Solution: Gradually acclimate them when moving indoors or outdoors.
Conclusion
By avoiding these 10 things your geraniums “hate”, you will enjoy stronger plants, more abundant flowering, and healthier foliage. Geraniums are quite forgiving when given the right conditions — just a little attention goes a long way!
