Water: Water generously but ensure good drainage for lobelia deckenii. Water should reach 15-20 cm deep, allowing the top 2.5-5 cm of soil to dry between waterings. It's not drought-tolerant and requires consistent watering, especially in gardens receiving under 2.5 cm of rain weekly.

Fertilize: Regular fertilization enhances the color of lobelia deckenii's blossoms. Initially, lobelia deckenii requires potassium, while blooming plants need balanced fertilizer. Use a quality liquid fertilizer with NPK ratios of 5:7:7 or 7:8:6, mixed with water, every two weeks during growth and bloom periods.

Pruning: Lobelia deckenii showcases beautiful blooms with a multi-branched structure. Prune in early spring, removing damaged branches and shaping for air circulation. Regular pruning fosters healthy growth and flowering, while avoiding late-season cuts prevents winter harm. Consistent care enhances both vigor and visual appeal.

Propagation: Lobelia deckenii thrives in its environment, requiring careful propagation through sowing. Use well-draining soil and maintain moisture without overwatering. A mild, stable temperature is crucial for growth. Gradually acclimate young plants to outdoor conditions before transplanting to their permanent site.
