To encourage abundant blooms, plant Coreopsis in full sunlight and ensure good soil drainage. Regular deadheading encourages continuous flowering and will help to delay the setting of seed prematurely. Water regularly, allowing the soil to become slightly moist before watering again. Lightly fertilize as excess fertiliser may lead to fewer blooms. Dividing perennials every few years will maintain plants in good vigor and health. These are easy home care tips for a long-lasting, colorful display in your garden.
