Fertilizing plants plays a crucial role in their growth and bloom production, and hibiscus are no exception. These tropical beauties, native to places like Mauritius and Fiji, thrive with proper feeding, resulting in vibrant flowers and healthy foliage.

For those cultivating hibiscus, whether in gardens or pots, regular fertilization is essential. This regimen ensures they showcase their spectacular blooms to the fullest. However, it’s vital to fertilize correctly to avoid potential pitfalls that could harm your plants.

Understanding the timing is paramount. Lotte Berendsen, a plant expert at PlantIn, advises on the best schedule: fertilize hibiscus once in early spring before new growth, again after the initial blooming in mid-spring, once more in mid-summer, and a final time at the end of fall. Avoid fertilizing during winter when the plant is dormant to prevent issues like root burn and rot from oversaturated soil.

Choosing the right fertilizer is equally critical. Look for balanced options like 10-10-10 or 12-12-12 NPK (nitrogen, phosphorus and potassium) ratios, or opt for higher phosphorus content to enhance bloom growth. Always follow manufacturer guidelines, particularly when using liquid fertilizers mixed with water. Lotte recommends diluting the feed to half strength or less to avoid overfeeding and potential root damage.

The frequency of fertilization depends on whether your hibiscus are in the ground or containers. Container plants can be fed monthly at quarter strength, benefiting from better drainage compared to ground-planted ones, which thrive with quarterly feeding.

By adhering to these expert tips, you can ensure your hibiscus receive the nutrients they need to flourish, producing abundant and stunning blooms throughout their growing season.
