Stunted Growth
Growth stagnation, noticeably smaller than same-species peers
Overview
Stunted growth means a plant has stopped growing or is growing extremely slowly, showing a clear size difference compared to healthy same-age plants of the same species. Possible causes include root restriction (rootbound pot), soil compaction, nutrient deficiency, or pest damage. Left unresolved, the plant will gradually weaken and may die.
Symptoms
No new leaf growth for weeks or months. Existing leaves are small, pale, or yellowing. Plant height and crown width remain static over long periods. Roots protruding from drainage holes indicate a rootbound condition. Hard, compacted soil surface causes water to run off without penetrating.
Treatment
Remove from pot and inspect roots. If rootbound, move to a pot 1-2 sizes larger, gently tease out circling roots, and add fresh potting mix. If soil is compacted, replace with a loose, airy mix (peat + perlite + coarse sand). Allow one week of recovery in indirect light after repotting, then begin light fertilization.
Prevention
Repot every 1-2 years in spring, going up 2-4cm in pot diameter. Use a potting mix with 30% perlite or coarse sand for aeration. Apply balanced liquid fertilizer monthly during spring and summer; stop in winter. Loosen the topsoil periodically to prevent compaction.
