Pruning Dead Branches on Japanese Maples

Dead limbs on a Japanese maple should be removed promptly. The tree gains no benefit from them, and removing them encourages new growth to fill the gaps. Use clean, sharp tools and cut back to live wood or the branch collar.

Sun tolerance varies among Japanese maple varieties. Dissected-leaf types generally prefer some afternoon shade, while broader-leaf cultivars like 'Bloodgood', 'Emperor 1', and 'Sango Kaku' can handle full sun if they are well-mulched and watered consistently during the hottest months. Mulch out to the drip line and irrigate deeply in July and August to reduce stress.
