How to Make Hibiscus Plant Grow Faster?
There are many things to keep in mind while caring for the hibiscus plant. By providing the right conditions, nutrients, and care, you can help your hibiscus thrive and grow faster.
1. Right Sunlight Exposure
Hibiscus plants need ample sunlight to thrive. They need at least 6 to 8 hours of direct sunlight daily for growth and blooming. When choosing a location for your hibiscus, look for a spot that receives plenty of sunlight.
Avoid placing your hibiscus in areas with intense midday sun to prevent sunburn and stress. Providing the right sunlight exposure will help your hibiscus plant flourish and produce beautiful flowers.
2. Well-drained soil
Ideal soil provides the necessary support, and nutrients for your plant’s growth. Hibiscus prefers well-drained soil, which means it allows water to pass through easily without becoming waterlogged. Loamy soil, a mixture of sand, and clay, is generally a good choice for hibiscus.
Whereas good drainage is essential to prevent water from pooling around the roots which can cause root rot issues. Well-drained soil ensures that excess water can escape, keeping the roots healthy. Also, hibiscus plants prefer slightly acidic soil in the range of 6.5 to 6.8. So, maintaining the soil slightly acidic is vital for their growth.

Watch the soil moisture levels and modify the frequency of watering accordingly to it, based on the weather conditions and the specific needs of your hibiscus. Infrequency of watering can result in hibiscus plant turn yellow leaves.
4. Proper fertilizing
Select a balanced fertilizer that is prepared for flowering plants. Look for one with a ratio of equal or slightly higher phosphorus content compared to nitrogen and potassium. This nutrient balance supports plant growth and encourages flower production.
Fertilize your hibiscus every four to six weeks during the growing season, which starts from spring to early fall. Avoid over-fertilizing, as extreme nutrients can lead to leaf burn and hinder blooming.
The soil must be moist when applying the fertilizer. This prevents potential root damage and helps the plant absorb nutrients more effectively. Water the hibiscus thoroughly after applying the fertilizer to ensure it reaches the roots.
