Brown crispy tips are the most misdiagnosed Devil’s Ivy problem in the country, because they look like thirst โ and the reflex is to water more. Sometimes that is right. Often it makes things considerably worse.
๐ First: Crispy or Soft?
This single distinction sends you down completely different paths. Get it wrong and you will treat the opposite problem.
๐ Dry & crispy
Tips and edges, brittle, papery. Often with a thin yellow halo.
Think: dry air, erratic watering, fertiliser salts, tap-water minerals, sun scorch.
๐ง Soft & mushy
Limp brown or black patches, often near the stem. Mix smells sour.
Think: overwatering and root rot โ see our root rot rescue guide.
๐ง The Cause People Never Suspect: Salt Build-Up
If you have been feeding your plant regularly, mineral salts from the fertiliser accumulate in the potting mix. Those salts burn the fine root tips, and the damage shows up at the furthest point from the roots โ the leaf tips and edges. A white crust on the surface of the mix or around the drainage holes is the giveaway.
๐ฟ How to flush the mix
- Take the plant to the sink or shower.
- Run water slowly through the mix for several minutes โ aim for roughly twice the pot’s volume of water.
- Let it drain completely.
- Hold off fertilising for a couple of months, then resume at half strength.
๐ฌ๏ธ Dry Air and Erratic Watering
Reverse-cycle heating in a Melbourne winter and air-conditioning in a Perth summer both strip moisture out of the air. Devil’s Ivy copes with normal household humidity, but it does not love sitting directly in the blast of a vent. Move it out of the airflow first โ that alone fixes a lot of cases.
The other common culprit is a swing between bone-dry and soaked. Letting the plant wilt hard before every drink damages the fine root tips, and the leaves record it. Consistency beats volume.
โ๏ธ What to Do With the Damaged Leaves
A brown tip will not turn green again โ that tissue is dead. You can trim it off with clean scissors, following the natural shape of the leaf, purely for looks. What matters is whether the new growth comes through clean. That is your evidence the fix worked.
โ Frequently Asked Questions
โ Should I mist to fix brown tips?
Misting raises humidity for a few minutes at most, so on its own it rarely fixes anything. Moving the plant away from a heating or cooling vent, and watering more consistently, does far more.
โ Only one or two leaves have brown tips. Should I worry?
No. A few older leaves showing wear is normal. Worry when it is spreading across new growth โ that means the underlying condition is still there.
โ Can too much sun cause brown tips?
Yes โ direct Australian sun through glass scorches leaves, but that usually shows as dry bleached or brown patches in the middle of the leaf where the light hit, rather than neatly along the tips and edges.
โ I flushed the soil and it is still happening. Now what?
Look at the roots. If the plant is severely root-bound, there is barely any mix left to hold water and the roots dry out between drinks. Repotting one size up is often the real answer.
