Vegetative Growth
2-4 monthsPlant produces new stems and elongated leaves with emerging color patterns; leaf size increases and branching develops
Fertilize every 2-3 weeks with balanced, diluted liquid fertilizer. Provide bright light to encourage vibrant coloration. Pinch stem tips to encourage bushier growth.

Prune to maintain shape and encourage dense growth. Reduce fertilizer frequency to monthly. Continue proper watering and light regime.
Dormancy/Rest
November-February (or during winter season)Growth slows significantly in fall and winter; leaf drop may occur if conditions are suboptimal; existing foliage may become less vibrant
