1. What to do if Trumpet Creeper is overfertilized

Although trumpet creeper likes fertilizer, be careful not to apply too much fertilizer, as excessive fertilizer can easily burn the roots. Therefore, if you apply too much fertilizer, you must deal with it as soon as possible. You can water the plants with clean water to dilute the fertilizer and let the fertilizer flow out. You can also directly repot the plant and replace the soil with new one to maintain it again. If you find rotten roots when repotting, cut them off and disinfect them, then replant them. They will recover soon.

2. When to fertilize trumpet creeper

The best time to fertilize trumpet creeper is in spring and autumn. These two seasons are its peak growth seasons and require a relatively large amount of fertilizer. Timely fertilization and sufficient nutrients are required to maintain growth needs. In addition, fertilize once before flowering. The flowering period is between March and May. Apply decomposed organic fertilizer once, and also apply phosphorus and potassium fertilizers during the flowering period to make the flowers bloom more brightly and last longer.

3. How to fertilize trumpet creeper

When fertilizing during the spring and autumn growing seasons, you should apply compound fertilizer, approximately once every 15 to 20 days, and use different fertilizers based on its growth needs. It can be applied directly around the root system and diluted with appropriate amount of water after application to promote faster absorption. During the flowering period, phosphorus and potassium fertilizers should be applied every 20 days or so. It is best to dilute them before applying to avoid fertilizer damage.
