When planting bulbs, it’s also essential to consider the soil quality and drainage. Bulbs generally prefer well-draining soil to prevent waterlogging, which can lead to bulb rot. Additionally, planting depths may be influenced by climate and local growing conditions, so it’s advisable to take those factors into account as well.
