My lime tree has been growing like crazy this winter and is now a whopping 3 feet tall (well almost). I know that this isn’t actually tall as far as trees are concerned, but since my lime is an indoor tree, if it grows much taller it’ll be a bit too big.
In order to halt vertical growth, and hopefully redirect growth horizontally to form branches, I’ve decided it’s time to head my lime. This involves chopping off the top few inches, which will remove the apical meristem. The apical meristem is responsible for the upward growth and also secretes hormones that inhibit certain other types of growth (like branches) from taking place near the top of the plant. Hopefully with it gone the lime starts to branch out and become more tree-like instead of looking like a leafy stick. I have no idea if it’ll work that way, but I’ll keep you updated.
