Growing from Seed

germination temperature in relation to outdoor temp

12 years ago

Here we have big contrast of morning and night temperature difference, in average about 20 degree difference. When the direction on the package says "germination: 68," do I sow the seeds outdoors when the highest or lowest temperature reaches to 68, or I will have to find a mid point?

Thanks

It is referring to the soil temperature, not air temps. Air temps are not relevant to germination so you have to measure the soil temp. If germinating indoors then the soil needs to be maintained at or near 68 and if direct seeding outdoors then the soil temp needs to be 68.

Soil temps don't change as quickly as air temps do so once the soil temp reaches 68 outside it would take several days of colder temps for it to fall.

Hope this helps.
