Here, you will learn what fertilizer works well and why. You’ll also find out when and how to fertilize your hibiscus plants.

When you shop for hibiscus fertilizer, you’ll see three numbers on product labels, known as the N-P-K ratio. These numbers signify the percentages of the three most important plant nutrients in that fertilizer formula.

The first number is every time nitrogen (N), known for promoting foliage growth. The second number shows phosphorus (P), usually touted for developing roots and promoting prolific blooms. The third number is potassium (K), which indirectly promotes root development and assists overall health and growth. Hibiscus chooses a ratio of medium-low-high.


Hibiscus suffer from nitrogen too high or too low. At low levels, plant lacks sufficient nutritional support. At high levels, nitrogen stimulates foliage at the expense of blooms. Too much nitrogen causes buds to drop and might burn roots and foliage.

Still, nitrogen is very essential. It moves easily through soil, so it leaches away with water and should be replaced. This is especially true if your hibiscus grows in a container. Hibiscus fertilizer needs a moderate nitrogen level in proportion to the other two numbers.


Many bloom-intensifying fertilizers contain high phosphorus. This isn’t well for hibiscus. Phosphorus doesn’t move willingly; it builds up over time. Too much soil phosphorus bind up other essential nutrients that hibiscus need to thrive.

The nutrients can’t be absorbed even when they are present. Instead of enhancing hibiscus flowers, high phosphorus inhibits them. Alkaline soil compounds the problem. Once phosphorus builds up, soil can take up-to a full year to recover. Always keep the middle number on your hibiscus fertilizer low.


Potassium is the most important nutrient for hibiscus blooms and overall health. It balances, regulates and supports all aspects of plant growth. Hibiscus flowers, with their vibrant colours and size, demand more potassium than other blooming flowers do.

High potassium helps foliage and flowers stay hydrated, and provide the nutritional support those magnificent flowers need. The last number on your fertilizer label, phosphorus should be the highest of the three.
