Mandevilla is a fast-growing vining plant that does well with routine fertilization. Feeding this plant supports abundant growth and blooms and keeps it looking its best. While fertilizing Mandevilla is helpful, it is important to understand the types of fertilizers and how often to apply them. Using the proper fertilizer at the right time will help Mandevilla flourish.
How to Fertilize Mandevilla
Rich soil with high organic content will support the Mandevilla's rapid growth and lovely flowers. Mandevilla appreciates soil that has a neutral to slightly acidic pH. Fertilizer will give the plant an extra boost of nutrition and keep the flowers coming during the summer. You can apply a slow-release fertilizer in the spring or a water-soluble fertilizer every few weeks during the growing season. Always water the plant before applying fertilizer so the roots can better absorb the nutrients.
Best Time To Fertilize Mandevilla
Spring is the best time to fertilize Mandevilla. This plant starts to grow in the spring, so feeding it as soon as new growth emerges will help the plant thrive and set summertime blooms. A slow-release granular fertilizer can be applied once during the spring. Hands-on gardeners can apply a water-soluble fertilizer every few weeks during the growing season.
Best Fertilizer For Mandevilla
The best fertilizer for Mandevilla will be balanced and have an NPK ratio of 10-10-10 or 20-20-20. Whether you use a slow-release or water-soluble fertilizer is a matter of preference. A slow-release fertilizer is applied once, and that’s it for the entire growing season. A water-soluble fertilizer needs to be reapplied during the growing season continually.
