Slow‑Growing Linden: Fertilizer Jump‑Start

5‑Year‑Old Linden with Zero Growth

If one of two identical lindens is stagnant, suspect root restriction (clay, compaction, girdling roots) or nutrient deficiency.

First Step: Fertilize

Apply 1 lb 10‑10‑10 per inch trunk diameter, scattered under canopy, watered in (before rain). This often triggers root expansion and canopy fill‑in.

If No Response in 6–8 Weeks

• Check for girdling roots (excavate root collar).
• Soil test for pH/nutrients.
• Consider air‑spade root zone decompaction.
