Question: My nana nandinas are yellow. They seem to look sickly all through the year. What do they need?

Answer: Probably iron. While all nandinas can show chlorosis in really alkaline, rocky soils, nana seems most likely to do so. Add an iron/sulfur soil acidifier to their planting beds several times during the growing season. Keep it off adjacent concrete and bricks. If you’re planting new nanas, prepare their soil carefully. For what it’s worth, it’s not uncommon for nana nandinas to play out and die within 5 or 6 years of being planted.
