Dear Gardeners,

I hope one of you can shed some light on the problem I'm facing with my avocado tree in a pot.

The hass avocado plant on the pictures is ~3 years old, has been in pots ever since it sprouted, repotted yearly. In the current container for about 8-9 months. It's about 2 meters tall.

It has always had steady growth, also during winter, but about one year ago some leaves started to slowly brown from the tips up. My remedy for this problem was cutting the browned part, but the process continues - the closer to the trunk, the faster. New leaves tend to look healthier (as on the pictures). The plant did not stop the growth, though.

I'm aware that avocados require certain humidity, and in the room where it's growing it's always around 40-50%. The sun exposition is also quite good, it stands right next to the south-eastern window. The soil is premade tree soil with peat mixed with sand. I also provide it with bio fertilizer.

Questions:
1. Is the browning of the leaves a natural process for avocado trees?
2. is there a way to stop it?
3. Is there something I'm doping wrong? Maybe it's the soil or root sickness?

I've decided to ask you as where I'm from (central Poland) the tree is obviously not native, the literature is very scarce and I have not met a single fellow gardener who could possible lend me a hand with this.

Thank you in advance for any tips you can share

Hi! gregz, welcome.

Try giving your avocado tree a bit more water.

Thank you, Kevalsha!

I'm watering it every second da, but I will give it a shot. Usually, when it does not have enough water, the leaves go down a bit.

Any other ideas what might be the case here?

I think your avocado looks fantastic! It's hard to grow one indoors. It does look like you have sufficient light, which can be a problem indoors. They do require a lot of water, but too much watering could cause the edges of the older leaves to brown. You might want to raise the humidity level a bit, houses inside are usually very dry, comparable to deserts sometimes! I have to have mine in for the winter, and I've found a cool mist humidifier to be a great help in keeping it healthy.

Thanks, gardenfish

It has a humidifier right behind it, which works every day to increase to levels to about 50% - I'll try to make it run longer in that case.
I wasn't aware that too much watering can cause the browning of the leaves too - that's good to know I'll leave the soil to dry a little longer before watering again.
