It’s about time to plant your garden for summer crops!! Well, in most places in North America, that is…
If you’re planting seeds or starts, you’ll need to know around when your last frost might be. Planting out too early can mean a disappointing beginning of the season.
There are things you can do to protect hardy seedlings and plants from frost. However, if you plant seeds too early your seeds and/or seedlings likely to rot from cold and wet, die in a frost or freeze, or at the least take a very long time to germinate – and with low rates of germination.
Where Do You Find Last Frost Information?
For the United States, the most comprehensive information comes from the National Climatic Data Center. There, you’ll be able to download a PDF showing many cities in your state, and the probability of light frost, heavy frost, or freeze (36, 32, and 28 °F).
They also have the same information in map form, if that is more helpful.
Weighing The Risks
Each of these resources will have different dates (as the Cheap Vegetable Gardener points out), plus this is the average last frost date – which means sometimes it happens earlier and sometimes it happens later, and there are always outlying years.
As a result, you’ll have to weigh the risks and decide for yourself. But at least these will give you more information upon which to measure those risks!
Other Areas Of The World
I had a tough time finding information for other areas, so if you have a resource please let me know in the comments and I’ll add it to the list!
Do You Have Other Resources?
Please share – thanks!
