- Feeding
- Under glass, use a loam-based, peat-free potting compost and bright filtered light; during active growth water moderately with a monthly balanced liquid fertiliser, and in winter water sparingly.RHS · read 13 September 2026
How this shows up on a Inch plant
Lower leaf blades collapse and yellow within days of a watering
On a inch plant the yellowing climbs from below. Affected leaf blades feel limp rather than papery, and water sits in the saucer long after it drains through.
The source for this plant describes moist but well-drained soil. Compost that stays saturated loses the air spaces fine roots grow into, and those roots die back first.
Telling it apart: Weigh the pot in your hand. A pot still heavy a week after watering is holding more water than the roots are using.

Most likely not enough light
- Full sun, Partial shade RHS · read 13 September 2026
Why: Far from a bright window, a inch plant builds leaves it cannot afford.
What to try:
- Move it closer to the brightest window you have, over a week or two rather than in one step.Useful: grow light
- Water less while it is in low light; a inch plant that is barely growing uses little.
What would settle it: Compare a new leaf with one from last year. Smaller and paler, with a longer gap below it, is the reaching pattern rather than a nutrient one.
Possibly its natural habit, or heat
Why: Close to a south window, light is seldom short, so stretching there is less likely to be reaching.
What to try:
- Turn the pot a quarter-turn each week and see whether the lean follows the window.
- Pinch out the growing tips to encourage bushier growth, if the inch plant is one that branches.
What would settle it: Whether it leans. A inch plant reaching for light bends toward the window; one growing to its habit, or growing fast in warmth, does not favour a side.
Possibly a lamp that is too far away or too weak
- Full sun, Partial shade RHS · read 13 September 2026
Why: The light a lamp delivers falls away quickly with distance, so a inch plant a little further from the lamp than intended gets much less.
What to try:
- Check the manufacturer's recommended distance for the lamp and measure it.
- Use a lamp made for growing plants rather than an ordinary household bulb.
What would settle it: Whether the growth nearest the lamp is more compact than the growth further away. A difference down the inch plant is a distance problem.

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
