|Hello! I have some podocarpas in redwood planters on a south-facing deck (lots of direct all-day sunlight) but their leaves seem to be turning yellow (rather than the original green they started out life as). The planters appear to be getting enough water (soil is usually damp and it has been a rainy spring so far). Can you offer some suggestions about what is causing this and what I can do to bring back the nice green color?
|Podocarpus prefers growing in light, slightly dry soils and will develop chlorosis where soil is alkaline or heavy and damp. I suspect that the planters have held too much water during the rainy spring and the result is a yellowing of the foliage. Although you can't control the rain, you can make sure the containers drain quickly, and you can fertilize with an acid-based fertilizer. Iron will help the foliage green up - use in amounts as listed on the label. Best wishes with your podocarpus!|
