Why 'Bloodgood' Japanese Maple Leaves Turn Green in Summer

'Bloodgood' Japanese maples naturally shift from spring's deep red to summer's bronzy-green, especially in shade. This isn't a problem—it's genetics and light response.

The Science

Red pigments (anthocyanins) protect young leaves from high light. In summer shade, the tree reduces anthocyanin production, revealing green chlorophyll. More shade = greener leaves.

What to Expect

• Spring: Deep burgundy-red
• Summer: Green with red undertones (variable)
• Fall: Brilliant crimson—reliably, every year

Maximizing Red Color

Plant in morning sun/afternoon shade. Avoid deep shade. Ensure adequate water—drought stress also fades color. But accept the seasonal shift; it's normal and healthy.
