My houseplants are getting brown tips. Why is that and what can I do to fix it?

Answer 1

You can improve this by letting th water sit overnight before you water. The chlorine and the salts in the water dissipate. Also some plants need extra humidity which can be achieved by putting a little gravel in the tray beneath them and put a bit of water in there. You do not want them to sit down in the water. Also you can mist them with a sprayer.

Answer 2

Julie is right.... It is most likely mineral salt build up... The only thing I can add to what she said is that before replacing the soil you could try "leaching" the plant: Take the plant outside or put it in the sink and let the water run from the top of the pot out the holes in the bottom for a good 10 minutes.... sometimes this can help to "rinse" the salt build up from the existing soil and you should see a difference on the new growth!

Answer 3

I would guess that you probably have a soil/nutrition problem. if the plants have been in the same pot for a while, you might have a build-up of salts (fertilizer) or the pH of your soil is out of whack. Potted plants typically need low soil pH to do well (slightly acid).

Try re-potting with some new potting soil. Use some controlled release fertilizer after re-potting.

After the tips go brown, they won't turn green again. you may need to trim the leaf tips to make them look nice again. Hopefully, any new growth will look much nicer with a good supply of fertilizer and fresh potting soil.

Good Luck!

Answer 4

If you live in a hard water region, you may have a mineral build up in the pot/soil. Try changing the soil and only using filtered water.

Answer 5

I have found that it could be a couple of things. It could be the chlorine in your water or it could be the lack of moisture in the air in your house. See the links below.

Answer 6

uneven watering causes this.
