Diagnosing a Dracaena 'Janet Craig' with Brown Leaf Tips

A Dracaena 'Janet Craig' is a low‑light plant that suffers when placed in a south‑facing window. The brown tips on your plant are a classic sign of too much light, improper watering, or mineral buildup from hard water or fertilizer spikes.

Light and Location

Move the plant to a spot with bright, indirect light—ideally a north‑facing window or a location away from direct sun rays.

Water Quality and Watering

Letting tap water sit for a few days removes chlorine but concentrates minerals. Switch to filtered or distilled water to prevent tip burn. Water thoroughly when the top quarter of the soil feels dry, and never let the pot sit in standing water.

Drainage and Fertilizer

Your pot lacks drainage holes, which is a major problem. Repot into a container with drainage, using a similar‑sized pot to avoid adding excess soil. Stop using fertilizer spikes—they create mineral hot spots. Hold off on fertilizing entirely for a year or two, then resume with a half‑strength liquid fertilizer if needed.

With these adjustments, your 'Janet Craig' should recover and maintain its deep green foliage.
