Dracaena 'Lisa' healthy for a year, now shortest stem browned and died, next shortest discoloring with brown leaf tips. Water <1×/week, no pooling, cork plate under pot. Should I repot or fertilize?

Diagnosis: Root Damage from Watering Issues

Symptoms indicate serious root damage — likely overwatering, possibly underwatering. Damaged roots can't absorb water, causing stem dieback and leaf tipping.

Light Check

• Must be within 6 ft of sunny uncovered window.
• If farther or window covered, light is insufficient → easy to overwater.

Watering Protocol

1. Keep in original nursery pot with original mix.
2. Check cache pot after watering — no standing water allowed.
3. In proper light: water ~weekly, just enough for trickle through drains.
4. Top ½ inch of mix should be barely damp before next watering.

What NOT to Do

• No repotting — destroys fragile roots.
• No fertilizer — not medicine, harms stressed plants.
• No root inspection — too risky, destroys root hairs.

Pruning

Cut off flopped/bent stems — they won't recover. Canes with no healthy leaves can be removed entirely.

Plant looks healthy overall — may be just one cane dying. Focus on precise watering + good light.
