Good soil preparation is recommended before planting the bulbs.
Make sure the soil is loose and free draining. A well-drained soil is a must or
bulbs will rot. On heavy soils, such as clay, add plenty of organic matter to
assist with this.
The spacing of bulbs depends largely on the effect you are trying to create.
The most effective display is obtained by planting in clumps.
Let the foliage on the bulbs die back before trimming it back or lifting the bulbs.
If healthy green foliage is cut back the bulb is unlikely to perform the following
year as it is during this time that energy is stored in the bulb for the next flowering
period.
You could always fill those gaps in your border by plugging them with bulbs grown
in pots. Buy a few extra bulbs, pot them up and keep them in a cool and sheltered
position over winter. Once they have started to flower, simply transfer them into
those empty spaces and they will grow happily in their new home. All types of
bulbs including narcissus, tulips, crocus and iris can be grown in pots.
Most bulbs need full sun, with exception of woodland bulbs such as bluebells, which need shade. As your garden matures and they become shaded, it may be worth lifting them and transferring them to a sunnier spot. |
