Why aren't my cucumber seeds coming up?

GOOD morning, what a lovely, perfect morning it is.  I do believe it will be like that all day.  Clear, blue sky with little wind, and after all the rain the green is everywhere.  Enjoy and take time to look around you as it is looking like spring. 
I have been hearing this a lot….” MY cucumbers, squash, or pumpkins didn’t come up.”  This year is the year we need to follow the rule after June 1st.  You can plant the vine plants from June 1st to the 15th for a very successful crop.  They don’t like cool or cold nights, and we have been having them.  Last year, we had a very warm May so you could plant them in May, and they would have come up.  But not this year.   Here are the conditions that you need for have any vine plants (cucumbers, squash, watermelon) come up.  Do you notice that the soil temperature should be 70 degrees?  That is the clue for success. 
I started mine 10 days ago and put on the propagation pad(heat pad) and they came up in 3 days.  Well water is the key also. 

     When to Plant Cucumbers
For an early crop, sow cucumber seeds indoors for about 3 weeks before you plan to transplant them outside into the ground. Provide bottom heat of about 70ºF (21ºC) with a heating pad or place the seed flats on top of a refrigerator or water heater. Sow two seeds an inch deep in each pot, then water well. Once the seedlings emerge, remove the weakest to leave one per pot.
Outdoors, cucumbers should be sown or transplanted into the ground no earlier than 2 weeks after the last frost date. Cucumbers are extremely susceptible to frost and cold damage; the soil should be at least 70ºF (21ºC) for germination. Seedlings set best at that temperature, too. (In cooler climates, warm the soil by covering it with black plastic prior to planting.)
Make successive plantings (every 2 weeks) for continued harvests through the season. In warm soil, cucumbers will grow quickly and ripen in about 6 weeks.
Hope this helps, so just need to be patient.  Plant the cucumbers by June 15th and you will have a crop.  I promise.
