Unusual Growth on Grand Duke Jasmine: Natural Variation or Fertilizer Effect?

Thick, dense, curling new stems on one plant may be natural variation. Check fertilizer: high nitrogen causes excessive green growth. Switch to balanced (12-12-12) or bloom-booster (high P/K) fertilizer for flowering shrubs. Monitor; if growth normalizes, it was likely fertilizer-related.
