My lemon plants (the two to the right) are about one year old now and they are planted from seed at the same time.
Nr 2: It stopped growing on the height for a while but instead developed two new seperate branches which are now growing slow but steady. It is about 45cm tall.
Nr 3: This plant is still growing on the height without the same branch development like nr 2. It is about 70cm tall. It seems like this one starts to tilt a little bit. It is quite hard to see on the picture (see red lines) below, but when I spray the leaves with water the plants gets heavier and it starts to tilt quite a lot. It makes me think that it's gonna break.
I've planted them in a citrus-compost-mix bought at the local plant store. They don't get enough sun as they should have but it seems enough to keep them happy and growing, slowly but steady.
In my own head I thought this way normal and that the lemon plant understand itself that it should focus om developing a stronger stem, but that is not the case yet.
Is this a normal behavior or do I need to do something about it? Is it time to prune? Should I support it in some way (with like a stick and some rope)?
