Hello, new to the forum, I really hope there is someone here who can help me!

I have been raising a coffee plant that started out about 20 cm high ( I do not know the type, I'm sorry!) for over ten years now. It has steadily grown over the years (in a pot) to it's current height of just under 2m. Last year was the first year it grew berries - I was so thrilled!

We moved houses 6 months ago. The plant is in an airy, sunny location, but without direct sunlight. In the last few weeks the leaves have been showing systoms of illness, almost as if they were being eaten, but I see no signs of infestation anywhere. I attach two pictures, plus a picture of the plant (sorry taken this evening at 7pm, but the room really is bright in the daytime). If anyone could tell me what to do and how to treat this I would be so greatful. I really do not want my plant to die...
I was also planning on changing its pot within the next couple of weeks...

Here's hoping my saviour is out there!

Your plant is reacting to the changes in its environment. Where you now have it does not provide enough light because it is off to the side of the window where it gets far less light than you realize. It really needs to be close to and directly in front of the window.

I don't know your watering routine and there is no single rule for how often to water it. If you are watering it the same as you did prior to the move, then you may be over watering because the light is now reduced. Allow the top half-inch of soil to dry before watering thoroughly. You may want to prune it back some to keep it from becoming leggy and overgrown. Prune when it is not in the midst of producing berries.

Thank you WillC for your answer. I will move the plant so it is directly in front of the window (though it actually gets more light now than before the move). As for watering, it seems to me to be a very thirsty plant, as the leaves start to wilt rapidly enough after a thorough watering. I do need to give it some 'engrais' (food).

How do I prune the plant? It is true that many of he branches are bare for at the the first half of the branch. There are no berries at the moment so I suppose I could prune it now.

Best to water thoroughly just before the leaves start to wilt.

Plant food is vastly over-rated and it is not medicine. I don't see any evidence that yours needs feeding. In fact, plant food is intended for plants that are healthy and growing vigorously.

In general, any stem can be cut back to any length and new leaves will emerge just below the point on the stem where you make the pruning cut and will grow upward from there. Prune it back to eliminate bare stems and to get it to the shape and size you prefer. But try to anticipate how it will look as new growth comes in.

Thank you once again for your help!
I have trimmed the bottom most branches, which were the oldest and most leggy. Moved in front of the window. WIll water before leaves droop.
Hopefully it will go back to being a happy plant!
Have a nice weekend!

Removing the lowest leaf stems will not eliminate the legginess. Pruning means cutting off the TOP section of any stem. Yes, that means removing a healthy portion of the plant, but it will not harm the plant. Pruning stem TOPS is done to get new growth to emerge lower down on that stem.
