When to Plant Alliums in Hardiness Zone 6
As you may have already guessed, you need to pay very close attention to your local weather in the fall. Specifically, you are going to need to watch when the first frost occurs.
In general, when there hasn’t been a frost for two weeks, you are SAFE to plant your alliums outside in Hardiness Zone 6!
Unfortunately, Mother Nature plays cruel tricks on us every year.
It should be noted that the above dates are just averages.
There are years when the first frost comes MUCH later. Sometimes, the first frost happens much earlier and you can get your alliums planted outside in Hardiness Zone 6 much more quicker.
Like I said before, you need to be very diligent in checking your local weather.
So what happens if a frost comes Before you plant your alliums?
When you know a frost is coming you need to take action.
- If alliums are in pots, bring them inside
- If alliums aren’t in the ground, make sure to plant them before the frost happens
Also, make sure not to plant your alliums in your garden too late.
- Planting alliums too early will cause small blooms or even worse, no blooms.
When Should You Start Your Allium Seeds Indoors?
Depending on the type of alliums, it takes roughly 21 days to grow alliums from seed indoors and then transplant them to your garden. And then another 360 days to bloom!
For a specific date that you should start allium seeds indoors you should:
- Find the first average frost date HERE
- And then subtract 21 days from it
Not only this, but I recommend again paying close attention to your local weather report.
It should also be noted that the best technique for bringing your allium plants outside is to introduce them (in their pots) outside for an hour. And then increase the amount of time they spend outside each day by an hour until they have been outside for 8 hours.
This will “harden” your allium plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
