Find answers about growing yellow Calibrachoa, choosing containers, and understanding the difference between seeds and named cultivars.
Calibrachoa can be grown from seed, but named Superbells cultivars are commonly propagated by cuttings. Plants grown from seed may not retain all the characteristics of a specific named cultivar. Check that the seeds are correctly identified and obtain variety-specific germination instructions from your supplier.
Use a hanging basket with drainage holes and a lightweight, well-drained potting mix. Place it where the plant receives several hours of sunlight, and water when the growing medium begins to dry. Hanging baskets can dry out faster than garden beds, so check soil moisture regularly and provide suitable space for trailing stems.
Reduced flowering can result from insufficient sunlight, excess moisture around the roots, nutrient imbalance, or unsuitable growing temperatures. Move the plant to a brighter location if needed, use well-drained soil, and follow a balanced feeding schedule. Check the foliage and stems for pests or other signs of stress.
