- Use Quality Soil: A well-draining, nutrient-rich soil mix helps support healthy root growth and vibrant blooms.
- Water Consistently: Keep the soil consistently moist but not waterlogged. Geraniums prefer slightly dry conditions between waterings.
- Fertilize Regularly: Use a balanced, water-soluble fertilizer every 4-6 weeks to promote continuous blooming and healthy growth.
- Prune and Deadhead: Regularly prune and deadhead geraniums to encourage bushier growth and more blooms. Remove spent flowers and any leggy or damaged stems.
By carefully selecting companion plants and providing the right care, you can create a stunning and healthy garden with geraniums as the centerpiece. Happy gardening!
