When it is time to plant bulbs, there are several things you can do to ensure they are inserted into the ground correctly. Knowing how deep to plant bulbs and prepare the ground are important.
Before you plant bulbs, read the instructions that come with them. It will give you customized information on how best to plant the individual bulb.

Being sure that your spring flowering bulbs are planted at the correct depth is important for overall plant health, as well as ensuring that the bulb will bloom. Different types of flowering bulbs need to be planted at different depths, but a good general rule of thumb is to plant the bulb at three times the height of the bulb. So, for example, if your bulb is two inches tall, you'd plant it six inches deep.
Another general rule is that the best depth to plant large bulbs is about 8-inches deep. Smaller bulbs should go about 5 inches underground.
