Fertilize: For 'silver bush,' use a balanced, slow-release fertilizer in spring and midsummer to promote growth and blooms, applying gently to prevent over-fertilization. Adjust frequency after flowering and follow safety instructions for application, enhancing overall health and vigor of 'silver bush.

Pruning: Silver bush, with silvery leaves and pale flowers, requires minimal pruning. Focus on dead branch removal and light trims in late spring post-bloom. Proper pruning improves air circulation and growth but avoid over-pruning. Clean tools to prevent disease; light maintenance yields best results.
