Maintaining your summer garden involves regular care and attention to ensure your plants thrive.

  1. Watering: Deep watering is essential for summer gardens. Water plants early in the morning to reduce evaporation and prevent heat stress. Ensure the soil remains consistently moist but not waterlogged.

  2. Mulching: Apply a layer of mulch around your plants to retain soil moisture, suppress weeds, and regulate soil temperature.

  3. Weeding: Regularly remove weeds to prevent them from competing with your garden plants for nutrients and water.

  4. Fertilizing: Use a balanced, slow-release fertilizer to provide essential nutrients throughout the growing season. Follow the manufacturer's instructions to avoid over-fertilizing.

  5. Pest Control: Monitor your garden for pests and diseases. Use organic pest control methods, such as neem oil or insecticidal soap, to manage infestations.

  6. Pruning and Deadheading: Regularly prune and deadhead your plants to promote healthy growth and prolong the blooming period.
