- Water at the base of the plant
- Reduce watering in cooler months
Meeting these care requirements will help your geraniums flourish. They'll add vibrant color to your Canadian garden or patio all season long.
Container Gardening and Landscape Design with Geranium

Greenhouse Cultivation and Winter Protection
Greenhouses help Canadian gardeners grow geraniums and other plants longer. They shield plants from harsh weather and allow year-round care. This controlled space extends the growing season significantly.
Overwintering Techniques
Protect geraniums during cold months with these methods:
- Bring potted plants indoors before frost
- Trim back foliage and store in a cool, dark place
- Take cuttings to propagate new plants
Temperature and Ventilation
Climate control is key for greenhouse cultivation. Keep daytime temperatures between 60-75°F (15-24°C) and slightly cooler at night. Good air flow prevents fungal diseases and boosts healthy growth.
Pest Management
Greenhouses can attract pests that harm geraniums. Check plants often to catch problems early. Try organic methods like neem oil or insecticidal soaps first.

Propagation and Maintenance Tips
Growing geraniums from seeds, cuttings, or division can expand your garden beautifully. For seed propagation, start indoors 8-10 weeks before the last frost. Cuttings are popular for perennial geraniums - snip a 4-inch stem and plant in moist soil.
Division works well for mature perennial varieties in spring or fall. Regular maintenance keeps geraniums healthy and blooming. Deadhead spent flowers and prune leggy stems to encourage new growth.
Pinch back growing tips on young plants for fuller, more compact Pelargonia specimens. These practices apply to both annual and perennial geraniums. Perennials may need less frequent attention.
Watch for common issues like leaf spot or root rot. Ensure proper air circulation and avoid overwatering to prevent these problems. Check for pests like aphids or whiteflies if you notice yellowing leaves.
A quick spray with insecticidal soap often solves pest issues. With proper care, your geraniums will thrive season after season.
