· Hi Julie,
What you've researched and found out about Firepower Nandina is true. It is drought, heat and mildew resistant. Consistently wet or soggy soil is most often the cause for this plant to defoliate and for the foliage to become irregular and often yellow or whitish in appearance. These plants simply must have very well-drained soil. I always recommend planting them in raised or mounded beds or on sloped ground.
Are your two plants planted side by side or in different locations? Check the soil around each plant to see if it is wet or dry. If the soil is wet you will have to lift it up, planting it in a mound. This way the roots won;t be standing in water.
