Some plants are antagonistic so must be kept apart!

"Best time for planting Alliums starts end of September till end October, or before it starts freezing they need to develop roots before the soil becomes solid. In general Allium bulbs need to have 3 to 4 times the height of the bulb of soil on top of them and most like mulching. They do like some old cattle manure (compost) when planting.

We are in zone 2 – 3 here and we grow them all outside in the open. In the wild they’re often covered with dead grass/twigs or bush, we give them a winter cover of leaves or straw.

In the growing stage they need moisture but after flowering, bulbs need warm and dry conditions to get ready for winter and the next flowering season.

It is wise to replant the big Allium bulbs every 2-3 years, as they will have used up all the necessary nutrients they need at that spot. At the same time you should divide the bulbs while planting, that way you will get extra Alliums. " from Alliums-Everywhere who sell them in Canada
