Bulbs are an excellent addition to your garden and will surely prove to be an interesting experience for you as a gardener.

As compared to other plants, planting bulbs is a little different. While planting bulbs, you should dig a deep hole to fit your bulb, make sure that the shoot of your bulb is facing upwards.
