Lemon Tree Mysterious Decline: No Clear Pathogen, Focus on Cultural Care

Jim's 8-month-old lemon tree blossomed twice, produced new leaves, then suddenly: new leaves stopped growing at emergence size, old leaves dying strangely (folding, yellow spots turning brown/rusty with holes). Photos provided via links.

Expert Assessment

Steve found no insect or disease evidence in photos. Recommended:

• Examine folded leaves internally for insects/webs
• Check watering: soil moist not wet (prevents root diseases)
• Let soil dry down if currently moist
• Water thoroughly, drain completely, repeat when dry
• Consult local garden center with plant for live diagnosis

Key Insight

Without visible pathogens, cultural issues (water management, possible chemical exposure) become primary suspects. The folded leaves suggest possible insect activity inside the curl, requiring close inspection.
