The images above show 1. a long-handled bulb planter, 2. the bulb planted at a correct depth in the hole of 3x its size, 3. the bulb pointy end up which is the correct way and 4. replacing the earth plug after planting.
Planting spring bulbs is easy, and a long-handled bulb planter comes in handy especially if you are planting a lot of bulbs. Most bulbs have a discernible flat end and a pointed end, or nose as shown in third top image. It's easy to remember the flat end goes at the bottom and the pointed nose end pointing upwards.
A bulb planter will make a regular hole just the right size for the bulb and the second image shows the bulb about 3 x its own depth in the hole. Cover with the plug or soil and no other attention is needed. Most bulbs with the exception of Tulips will re appear each year and flower well.
