How To Prevent Late Season Poinsettia Problems

Preventing Late Season Poinsettia Problems

To maintain healthy late-season poinsettias, growers should be aware of common issues that can affect these plants.

According to Clayton Humble, Patrick Veazie, and Brian E. Whipker of North Carolina State University, some of the most common problems include disease, environmental, nutritional, and pest issues.

Nutritional Issues

One common nutritional issue is magnesium deficiency, which can occur when using 20-10-20 fertilizers in areas with low magnesium in the water source.

“can easily develop with the use of 20-10-20 in areas that lack Mg in their water source, especially when the Mg contribution from any dolomitic limestone leaches out of the pot over time.

Growers can take preventative measures to avoid these problems and ensure their poinsettias remain healthy.
