Lemon Tree help
Last year I purchased two seedling lemon trees, along with two seedling orange trees. The orange trees are flourishing very well. The lemon trees, on the other hand, had some issues. A few months back they started to grow thorns and lost their leaves. One of the trees lost all its leaves and died. The other, pictured here, made a recovery. However, I am concerned by the placement of its lower branches. These branches grew after its recovery and I am concerned that they may be too low (like "suckers"). Should I leave them be or are they just sapping energy from the main trunk?
Also, would it be possible to use rooting hormone on one of these branches in order to replace the tree that was lost?
Thanks for your advice!
