Transplanting White Pine into Heavy Clay: Drainage Critical

5-ft, 5-yr white pine (1.25" trunk) moving from loamy clay to hard brown clay.

Timing

Now (fall) or early spring. Fall: 6+ weeks before freeze.

Clay Planting Protocol

• Root ball: 9–12" wide per 1" trunk (11–15" for 1.25")
• Hole: 2× ball width, same depth
• Critical: Roughen hole sides (glazed clay seals)
• Punch drainage holes in hole sides
• Backfill: Quality topsoil/potting mix
• Mulch 3", water 1" every 3 days initially

Watering Schedule

• Every 3 days × 2 months (no rain)
• Then weekly × first growing season
• Pan method for accuracy

Drainage holes prevent "bathtub effect" in clay. Essential for survival.
