Care Guide
💧 Water
☀️ Light Full sun
Sea rosemary comes from open habitats, like sunny meadows and forest edges, which offer plenty of light. It grows best in full sun but can also tolerate partial sun, adjusting well to different light levels.
🌡️ Temperature 20–37.8°C
Sea rosemary comes from tropical areas, where the weather is usually warm and humid. Consequently, it is adapted to high heat and moisture. It does not tolerate sudden temperature shifts and prefers a constant temperature, so avoiding indoor temperature fluctuations is important. It typically cannot withstand cold and needs higher temperatures to grow. If the surrounding temperature falls too low, the plant may stop growing or even die.

🪴 Soil 6-7
🌱 Fertilizer
The best time to fertilize a Sea rosemary is in early spring as it breaks dormancy. This encourages overall growth and flower production. Fertilizing improves foliage, stems, and branches, and promotes large, vibrant, long-lasting flowers. It also helps move nutrients from the roots to the blooms and enhances the plant's health and disease resistance.
