Remove yellowing lower leaves throughout summer; pinch out the growing tip in late summer (August in the Northern Hemisphere)
How often
Remove lower leaves every 2–3 weeks; top once in late summer
Technique
Snap or cut yellowed leaves cleanly at the stem as they appear. In late summer, snap or cut the main growing tip (the top few centimetres) once you can see small sprouts forming along the stem — this halts upward growth and tells the plant to put energy into maturing existing sprouts.
