How much time does it take for squash seeds to germinate?

Sow the seeds 1/2 to 1 inch deep and space them apart 12 to 18 inches, as the squash plants can become quite large. Seeds should germinate within 7 to 10 days if the weather is warm enough. If you are transplanting seedlings to the garden, wait until it has been 2 to 3 weeks after the last frost.

If your soil is very sandy or the weather is smoking hot, you'll need to water more frequently.

How cold is too cold for veggie germinating seeds?

Will seedlings be OK in 40 degrees?

Can seedlings survive 40 degree weather?

Hardy vegetables tolerate cold temperatures the best—their seeds will germinate in cool soil, and seedlings can typically survive heavy frost. Plant these seeds or transplants two to three weeks before the date of the average last spring frost; they will grow in daytime temperatures as low as 40 degrees Fahrenheit.

Is 40 degrees too cold for seeds?

What helps seeds germinate faster?

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
