  4. Fertilize as needed: Apply a balanced, slow-release fertilizer to your annuals and perennials to provide them with the necessary nutrients for optimal growth and bloom production.
  5. Deadhead spent blooms: Removing spent flowers encourages continuous blooming and keeps your plants looking tidy throughout the summer.
  6. Mulch around plants: Apply a 2-3 inch layer of mulch around your plants to help retain moisture and suppress weed growth, allowing your flowers to thrive without competition.

By incorporating these summer flowering plants into your garden and following the recommended planting and care tips, you’ll be rewarded with a vibrant, long-lasting display of blooms that will transform your outdoor spaces into a true summer paradise.
