Fertilizer:
During growing season (spring to early autumn):
Use a balanced liquid fertilizer every 4–6 weeks.
Optional: Use compost or worm castings for organic feeding.
Reduce or stop feeding in winter when growth slows.
⚠️ Avoid over-fertilizing—can cause leaf burn and chemical buildup in soil.
✂️ Pruning and Maintenance
Trim yellowing or dead stems at the base regularly.
Light pruning helps maintain bushy, compact shape.
Remove old stems in early spring to promote fresh growth.
Wipe leaves gently with a damp cloth to remove dust.
