Fertilizing Schedule 🍽️

Feed your plants with a balanced fertilizer every 4-6 weeks during the growing season. This will support robust growth and vibrant blooms.

Pruning Methods ✂️

Pruning is essential for maintaining shape. Trim back any leggy growth in early spring before new growth begins to encourage a bushier appearance.
