Fertilizing Your Bluebeard Plant:
The Dos and Don’ts

Bluebeard, also known as caryopteris, is a beautiful shrub that produces stunning blue flowers in late summer and early fall. To keep your bluebeard plant healthy and blooming, it’s essential to fertilize it properly. In this article, we’ll cover the dos and don’ts of fertilizing your bluebeard plant.

Dos

Do fertilize your bluebeard plant in the spring

In early spring, when the plant starts producing new growth, it’s an excellent time to fertilize. Use a slow-release fertilizer that will gradually release nutrients over time. This type of fertilizer will provide your bluebeard plant with the nutrients it needs throughout the growing season.

Do water your bluebeard plant before fertilizing

Before fertilizing your bluebeard plant, make sure the soil is moist. Water your plant thoroughly a day or two before applying fertilizer to prevent burning the roots.

Do use a balanced fertilizer

A balanced fertilizer contains equal amounts of nitrogen, phosphorus, and potassium. A 10-10-10 or 20-20-20 fertilizer is ideal for bluebeard plants. Nitrogen promotes leafy growth, phosphorus encourages flowering, and potassium helps with overall plant health.

Don’ts

Don’t over-fertilize your bluebeard plant

Over-fertilizing can harm your bluebeard plant by causing root burn or excessive foliage growth at the expense of flowers. Follow the instructions on the fertilizer package carefully and avoid applying more than recommended.

Don’t fertilize your bluebeard plant in late summer or fall.

Avoid fertilizing your bluebeard plant in late summer or fall when it’s preparing for winter dormancy. Applying fertilizer at this time can stimulate new growth that may not have time to harden off before winter, making it more susceptible to damage or death.

Don’t use a high-nitrogen fertilizer

Using a high-nitrogen fertilizer can promote excessive leafy growth at the expense of flowers. Bluebeard plants need more phosphorus than nitrogen to produce abundant blooms.
