Every bulb has a basal plate from which the roots and leaves grow. Most bulbs have a thin basal plate but in some it can grow thick.
Three mature Football lily bulbs, the centre one has thin basal plate but is bigger than the others. This thicker basal plate is an advantage or a dis advantage? Should I leave it as it is or slice it thin. Arif
An extract from bulb forum Garden Web, This is what Paul of Royal Colors said about this slicing of basal plate when I asked him about the topic. Paul or Royal Colors is in no way connected with the suppliers of these HD bulb kits.
"This is absolutely not harmful for the bulb. It is even better to this, because the bulb MUST now make new roots and the bulb WILL do this. All professional growers do this with older bulbs to make them younger and more vital. After 3-4 growing seasons the basal plate is thick, old and will hardly make new roots. By cutting of the complete basal plate, and 1 new growing season, the bulb will have a beautiful new, vital root system. Also will the bulbs grow better with their new roots!!"
