Yes, Plumeria can benefit from mycorrhizal inoculants, which are beneficial fungi that form a symbiotic relationship with plant roots. These fungi extend the plant’s root system and help improve nutrient and water uptake. The mycorrhizal network enhances the plant’s ability to access nutrients, especially phosphorus and micronutrients, which can be particularly advantageous for Plumeria. Using mycorrhizal inoculants during planting or repotting can improve the plant’s establishment and overall growth. Follow the manufacturer’s recommendations for the appropriate mycorrhizal product and application rate.
