The images show how to plant spring bulbs
1. Dig a hole with a long-handled bulb planter.
2. Plant the bulb at a correct depth in the hole, which is 3x its size. This means the smaller bulbs, snowdrops, crocus will be planted at a shallower depth than larger tulip bulbs.
3. The pointy end of the plant goes up, which is the correct way
4. Replace the earth plug after planting.
5. The correct planting depth is important.
I find planting spring bulbs much easier with a bulb planted, and preferabley a long-handled bulb planter especially if you are planting a lot of bulbs. Crocus has a good selection, affiliate link to Bulb planters.
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.
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.
