For geranium landscaping, consider these planting tips:

• Space plants 12-24 inches apart in garden beds
• Use geraniums as colorful borders or in mass plantings
• Mix varieties in container gardens for visual interest

When transplanting, gently remove geraniums from their nursery pots. Loosen the root ball and place the plant in a wide hole. Fill with soil, water well, and add mulch around the base.

For container planting, choose pots with drainage holes. Use a quality potting mix for best results.
