Corn Plant (Dracaena massangeana) Brown Tips & Spots: Root or Water Issue

A 3-foot, 3-stalk corn plant in a 12-inch pot (18 months since repotting) has brown dried tips and whitish-gray edge spots on new and old growth. 3 feet from west window.

Root Check

Look for roots emerging from drainage holes or a dense mat at the bottom of the root ball. If found:

• Cut off circling/bottom roots.
• Add 1 inch fresh potting mix to pot bottom.
• Reset root ball on top.

If Roots Are Fine

• Water thoroughly when top 2–3 inches dry.
• Switch to filtered/distilled/rainwater if tap is hard.

Why This Works

Root binding or salt buildup from hard water causes tip burn and edge spotting. Fixing root zone or water quality stops new damage.
