Maximizing Growth of 300 Bare-Root White Pines

300 three-year bare-root white pines (12–18 in) planted in tilled rows for a screen. All green after good rains. Owner asked how to maximize growth rate over coming years.

The expert recommended mulching (pine straw) to suppress grass/weeds and retain moisture. After one year, fertilize with 10-10-10 at ~1 cup per tree in spring and early fall. Later, 1 lb per inch trunk diameter. Water in fertilizer or apply before rain.

Growth Acceleration

• Mulch heavily with pine straw.
• Year 1: no fertilizer.
• Year 2+: 10-10-10 spring & fall.
• Scale fertilizer with trunk diameter.
