Water:
Wild Petunia prefers moist, well-drained conditions and benefits from weekly watering. While it has moderate drought tolerance, consistent moisture is vital for its growth. Typically grown outdoors, wild Petunia thrives with natural rainfall while maintaining soil moisture without waterlogging is essential for its health.
Fertilize:
For optimal growth, wild Petunia requires a balanced fertilizer: a granular, slow-release application in spring, then a monthly liquid fertilizer during blooming. Avoid over-fertilizing and adjust feeding during growth phases. Always water wild Petunia after fertilization to ensure even nutrient distribution.
Pruning:
Wild Petunia boasts vibrant, funnel-shaped flowers and prefers moist, shady areas. Prune in early to late spring, removing dead stems and trimming one-third of the plant to encourage bushier growth and prolific blooming. Use sterilized tools to avoid disease, ensuring wild Petunia remains vigorous and attractive.
Propagation:
Wild Petunia prefers direct sowing in well-draining soil and sunny spots. Lightly cover seeds and maintain moisture without overwatering. Thinning seedlings prevents overcrowding. Regular watering and balanced fertilizer contribute to healthy plant establishment.
