How many allium bulbs should I plant together?Updated 21 days ago

You can plant one bulb per hole, or dig a wide hole or trenches and plant several at a time. Just ensure the bulbs are spaced correctly—generally this should be around 2-3 times the width of the bulb apart. If planting in small groups, odd numbers look better, e.g. 3, 5 or 7. Upwards of 7 bulbs it does not matter whether the number is odd or even.
