Prep Your Garden for a Vibrant Season
Before planting in the Treasure Valley area, prepare your flower bed by choosing a well-drained location with the right amount of sunlight for your flowers. Clear the area of weeds, rocks, and debris. Amend the soil with compost or organic matter as needed, and loosen it to a depth of 6-8 inches for better root growth. Plan your flower layout with taller plants in the back and shorter ones in front to create a balanced, vibrant display. These steps will ensure your garden is set up for success and blooms beautifully throughout the seasons.

*Special garden tip*
For a stunning, low-maintenance garden, group your flowers based on their water needs. Pansies, coneflowers, and blanket flowers thrive with regular watering, while drought-tolerant plants like lavender, Russian sage, and lupine prefer to dry out between waterings. Planting them in clusters with similar water requirements not only makes maintenance easier but also helps each flower reach its full potential. This simple tip will keep your garden healthy and vibrant with less effort!
