Practicalities

  • Flower bulbs should generally be planted at a depth that is three times the height of the bulb. Deeper planting helps protect the bulbs from temperature fluctuations and encourages stable growth.
  • Most bulbs have a specific orientation for planting. Pointed ends usually face upwards, while the flat or root ends should be planted facing downward. Planting bulbs in the correct orientation ensures proper growth.
  • Well-draining soil is crucial for flower bulbs. Bulbs are susceptible to rot if planted in waterlogged soil. Adding organic matter to the soil can improve drainage.
  • To achieve continuous blooms, consider planting bulbs with different bloom times in layers. This technique, known as lasagna planting, involves placing bulbs with later bloom times on top of those that bloom earlier.
  • After flowering, leave the foliage intact until it turns yellow and withers. This allows the bulb to store energy for the next growing season. Bulbs can be lifted and divided every few years to rejuvenate crowded clumps.
