Leggy Growth on indoor lemon
What's Happening
Juvenile lemon seedlings exhibit strong apical dominance, prioritizing vertical growth over lateral branching. Indoors, this is amplified by low light levels, resulting in single-stemmed, leggy plants that struggle to fit in windowsill spaces.
How to Fix It
- 1
Top the leading shoot 1/4 inch above a node once it reaches 6-8 inches.
- 2
Repeat topping on new regrowth every 4-6 weeks to repeatedly disrupt auxin flow and activate lower axillary buds.
- 3
Provide 12-16 hours of full-spectrum light to reduce etiolation and promote shorter internodes.
- 4
Apply diluted seaweed extract to boost cytokinins, which encourage lateral bud break.
How to Prevent It
Position for maximum direct sun. Transition to dwarf rootstock clones for compact growth. Use reflective surfaces to amplify light from all sides.
