Oxalis leggy growth

Long, weak stalks leaning toward a window suggest the plant is reaching for light. Normal leaflet folding at night is a separate movement and does not indicate legginess.

Improve the position before trimming

Move common false shamrock toward brighter light, introducing direct sun gradually. Rotate occasionally to balance growth; rotation alone cannot make a dim location brighter.

Once new leaves emerge on stronger stalks, remove the weakest older stems at their bases. Keep moisture steady during active growth, reducing watering if the plant enters a genuine dormant phase.
