How to plant alliums
Fill half the pot with compost. We are using a general purpose compost mixed with coarse sand. We planted the bigger bulbs of Allium gladiator deeper.
Then cover with a layer of compost and planted the 5 mixed bulbs.
Another layer of compost and, finally the smaller bulbs of Allium sphaerocephalon near the surface.
Cover with a last layer of compost and you are done. We can’t wait to see the result…
