Undoing Harmful Repotting of a 50-Year-Old Ornamental Orange Tree

Why Mature Plants Should Never Be Repotted

A 50-year-old ornamental orange tree repotted into a heavy pine bark/sand/peat mix with "drainage material" at the bottom is in shock—droopy, dropping leaves. The mix lacks porosity; drainage layers are a myth. The large pot retains water, causing root rot.

Emergency Correction

• If original rootball was kept intact: remove tree, strip all added soil and drainage material, return to original pot.
• Do NOT fertilize until vigorous recovery.
• Leaf loss may be seasonal (shorter days) or from lack of pruning.

Mature potted plants are stable; they need occasional fertilizer, not new soil. Bad advice caused this crisis.
