I've been growing my avocado plant since last summer but recently the tips of its leaves are turning browny/yellow and are drying out - one even breaking off. I've read in some places that it might be salt burn but I want to check again and also see if there's anything I can do to help it? One of the leaves has also started developing small holes - is this just from a bug or something else? Thank you!!

Update: I had just watered it and it seems to be getting better now I run water through the soil weekly to flush out excess salts and the new leaves seem to be healthy

Thank you for the advice

Are the leaves sticky? Or did you just water it?

Have you been giving it fertilizer all through the winter months? How about the amount of water?

Indoor plants to experience "winter" even though they are in your house. If they're growing by a window, which surely your avocado would be, they get less intense light, and a shorter amount of daylight as well as probably getting cooler at night. This causes them to slow down growing so you need to respond by slowing down or stopping fertilizer and using less water in winter as well.

What you have looks like it could be fertilizer burn to me although your new leaves at the top look good. The hole in the leaf would certainly be from a bug, or something else like mechanical damage and not a disease. I wouldn't worry too much about it unless you start seeing a lot more of them. Check the backs of the leaves for tiny green caterpillars if more holes appear. Just pick them off with your fingers - you can see them really well if you use a flashlight.

It might be time to give your plant a bigger pot. When you do re-pot it, give it a good long soak - a couple of hours maybe - in tepid water beforehand. This will get it all nicely hydrated, and also flush out any accumulated salts from old fertilizer that are hanging around in the pot. Be sure to rinse the saucer as well too before you re-use it.
