Do you want to grow spring flowers in Delaware, but don’t know when to plant them?
Planting spring flowers is not as easy as it seems.
- Spring Flowers are not able to survive frost or cold weather under 40 degrees Fahrenheit.
So if you plant them outside too early in the spring they will die. And if you plant them too late, your spring flowers won’t bloom or may have a short, small bloom.
Today, I’m going to teach you the ideal time to plant spring flowers in Delaware:

When to Plant Spring Flowers in Delaware
As you may have already guessed, you need to pay very close attention to your local weather in the spring. Specifically, you are going to need to watch when the last frost occurs.
In general, when there hasn’t been a frost for two weeks, you are SAFE to plant your spring flowers outside in Delaware!
For your reference, I have created this table for average frost dates for most major cities in Delaware. If your city is not listed below you can find its Last & First Frost Dates HERE.
Delaware Last & First Frost Dates
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 last frost comes MUCH later. Sometimes, the last frost happens much earlier and you can get your spring flowers planted outside in Delaware much quicker.
Like I said before, you need to be very diligent in checking your local weather.
So what happens if a frost comes AFTER you plant your spring flowers?
When you know a frost is coming you need to take action.
- If spring flowers are in pots, bring them inside
- If spring flowers are in the ground, cover them in burlap and hope they survive
Also, make sure not to plant your spring flowers in your garden too late.
- Planting spring flowers too late will cause no bloom or a short, small bloom.
When Should You Start Your Spring Flower Seeds Indoors?
Depending on the type of spring flowers, it takes roughly 40-80 days to grow spring flowers from seed indoors and then transplant them to your garden.
For a specific date that you should start spring flower seeds indoors you should:
- Find the last average frost date HERE
- And then subtract 40 – 80 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 spring flower 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 “hardened” your spring flower plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
