Meyer Lemon Leaf Edges Yellow: Miracle-Gro Salt Buildup Suspected

Diagnosis

Yellowing starting at leaf tips and moving inward on Meyer lemon, while other citrus tolerate Miracle-Gro, suggests salt toxicity from that fertilizer. Miracle-Gro’s carrier salts accumulate in pots, burning roots.

Evidence

Yellow-brown residue on pot sides, soil surface.
Undissolved salts in fertilizer solution.
Many gardeners report recovery after stopping Miracle-Gro.

Action

Switch to slow-release citrus fertilizer.
Leach pot thoroughly with clean water.
Repot if salt buildup is severe.

Test by growing one plant without Miracle-Gro for comparison.
