Understanding Geraniums

Geraniums, or Pelargonium, are a diverse group of flowering plants that are popular for their bright blooms and aromatic leaves. They are often grown as annuals in temperate regions but can be perennial in warmer climates. Geraniums thrive in well-drained soil and full sunlight, making them a favorite choice for gardens and containers.

Geranium Varieties

• Zonal Geraniums: Known for their distinctive leaf markings.
• Regal Geraniums: Noted for their stunning flowers and compact growth.
• Ivy Geraniums: Popular for hanging baskets due to their trailing growth habit.

Effects of Low Temperatures on Geraniums

Low temperatures can have various effects on geraniums, ranging from stunted growth to flower drop. Understanding these effects can help you take proactive measures to protect your plants.

Temperature Thresholds

Geraniums are sensitive to temperatures below 50°F (10°C). Prolonged exposure to cold can lead to:

• Wilting leaves
• Discolored foliage
• Reduced flowering

Preparation for Cold Weather

Preparing your geraniums for cold weather is essential for their survival. Here are some key steps to take before the frost sets in:

Timing Your Preparations

Monitor weather forecasts closely and be ready to act when temperatures are expected to drop. Generally, preparation should begin in late fall.

Pruning and Cleaning

Prune dead or damaged leaves and clean the area around your geraniums to prevent pests and diseases.

Indoor Care for Geraniums

If you're bringing geraniums indoors for the winter, it's crucial to provide them with the right environment:

Lighting Requirements

Geraniums require plenty of light to thrive. Place them near south-facing windows or use grow lights to ensure they receive 8-10 hours of bright light daily.

Humidity and Temperature Control

Maintain indoor temperatures between 65°F to 70°F (18°C to 21°C) and ensure adequate humidity levels to prevent stress on the plants.

Outdoor Care for Geraniums

If your geraniums remain outdoors during the colder months, consider the following care tips:

Mulching

Apply a layer of mulch around the base of your geraniums to insulate the roots and retain moisture.

Covering Plants

When frost is forecasted, cover your geraniums with frost cloths or blankets to protect them from cold damage.

Common Pests and Diseases

Even in low temperatures, geraniums can be susceptible to pests and diseases. Here are some common issues to look out for:

Pests

• Aphids
• Spider mites
• Whiteflies

Diseases

Watch for signs of fungal infections, which can thrive in damp conditions. Ensure proper air circulation and avoid overhead watering to minimize disease risk.

Propagating Geraniums

Propagation is an excellent way to expand your geranium collection. Here’s how you can do it:

Stem Cuttings

Take 4-6 inch stem cuttings from healthy plants and place them in water or soil to root. Keep them in a warm, bright area until roots develop.

Seed Propagation

Geranium seeds can also be sown indoors 6-8 weeks before the last frost date for a head start on the growing season.

Conclusion

In conclusion, understanding how to care for geraniums during low temperatures is vital for maintaining their health and beauty. By preparing your plants for the cold, providing adequate indoor care, and being vigilant against pests and diseases, you can ensure your geraniums thrive despite the challenges posed by winter weather.
