In early spring, provide a light feeding with a balanced fertilizer to kickstart growth. This simple step can significantly enhance the health and blooming potential of your plants.
Pruning and Ongoing Care βοΈ
Regularly deadhead spent flowers to encourage more blooms throughout the season. Additionally, keep an eye out for pests and diseases to maintain the overall health of your plants.
Outdoor vs. Container Growing π‘
For container growing, choose a large pot with drainage holes to prevent water accumulation. If planting outdoors, ensure adequate spacing between plants for proper air circulation, which helps reduce disease risk.
