Leggy Growth / Stretching
Leggy growth means long, stretched stems with wide gaps between leaves. The plant is reaching for more light.
可能原因
Insufficient Light
Why: Plants stretch toward the nearest light source, producing elongated stems with fewer leaves.
Signs to check: Long internodes (gaps between leaves), stems lean toward windows, sparse foliage.
Seasonal Light Changes
Why: Shorter winter days reduce available light, causing plants to stretch.
Signs to check: Growth becomes leggy during fall and winter months, normalizes in spring.
Overcrowding
Why: Plants competing for light in a crowded arrangement will stretch to rise above their neighbors.
Signs to check: Multiple plants grouped tightly, all reaching in the same direction.
檢查要點
- 1Assess the quality and duration of light the plant receives
- 2Note whether the plant leans toward the light source
- 3Compare current growth to earlier, more compact growth
- 4Check if the season has reduced available daylight
處理方法
- Move the plant to a brighter location with more indirect light
- Rotate the pot regularly so growth is even on all sides
- Consider supplemental grow lights during winter
- Prune leggy stems to encourage bushier regrowth
- Propagate cuttings from pruned stems if desired
何時尋求幫助
- Stems are so thin and weak they cannot support the plant
- Leaves are extremely small and pale in addition to leggy growth
關鍵要點
Leggy growth is almost always a light issue. Increase light exposure and prune to encourage compact, healthy growth.
