In summary, what you need to know:

NameAllium giganteum

Flowering : May to July

Easy to grow, it is perfect in beds or in pots and planters to adorn terraces and balconies.

Planting allium

The allium giganteum is planted in the fall about 10/12 cm deep in light soil.

  • The allium likes sunny situations
  • The soil should be light and well drained, even poor

A good benchmark to know the depth of planting is to multiply the size of the bulb by 3. If it is 5 cm high you will therefore plant it at 15 cm.

  • Proceed in groups of 10 to 15 bulbs to create beautiful splashes of color.
  • Space each bulb about 20 cm apart.

Caring for an Allium

The maintenance of the allium is very simple as the care to bring to this bulbous perennial is limited.

In the ground or in a pot , you will enjoy its beautiful flowering without having to worry too much about it.

  • Cut off faded flowers as you go, cutting the stem as close to the ground as possible.
  • Cut the foliage only when it has yellowed because this is when it builds up its reserves for the next flowering.
  • No fertilizer input is necessary.

It should be noted that the leaves of the allium tend to wilt before or during the flowering of the large umbels and that it is therefore interesting to plant ground-covering perennials at the base in order to cover the withered leaves and leave only the stem protruding.

For the culture of the allium in pot , do not forget to water regularly because the needs in water are more important because of the rapid drying of the ground in pot.
