Forget-me-not flowers are hard to transplant because they grow deep in the soil. The process of transplanting them may require some digging, which can cause damage to the plant.
One way to do it is by using a spade. You would also need some patience and a lot of care while transplanting these flowers because they are delicate plants that need special care and attention.
In order to prevent shock, use your fingers or a trowel to break apart the root ball so you can see the true shape of it before planting. You can also use your hands, but make sure not to rub off any soil on your skin as it will be difficult for you to get all of it off later on.
