Some of the flowers seeds sown straight into the ground end of May have not yet germinated?

I suspect the cold and persist rain is to blame. Can I say goodbye to them ever germinating this summer?. Zinnas and Cosmos seeds were sown never germinated whilst cornflowers and others seeds have germinated.

Some of the flowers seeds sown straight into the ground end of May have not yet germinated?
Some Zinnias take 5-7 days to germinate, other varieties can take 7-10 days when temperatures are at 70 degrees.

Cosmos plants will germinate in 7 - 21 days when the soil temperature is optimum for germination at 70 - 80 degrees F.


" If the early spring has been cold, soil temperatures will remain cool also. If the soil temperature is below 65 F., seeds may not germinate as rapidly."

If you have had at least 70 degree temperature (for the time required to germinate) %26amp; your other flowers with similar temperature requirements have germinated, your Zinnia %26amp; Cosmos seeds should have also germinated by now. Maybe you got some bad seeds. You can see if you can get a refund or replacement. Zinnia seed may be sown up until the end of July.





Keep in mind that Cornflowers start germinating at a lower temperature, so it's reasonable to assume that they can germinate earlier than Cosmos:


Cornflower/Bachelor's Button ... Germination: 7-25 days. Optimum soil temperature for germination: 60-70F. Sowing depth: 1/8"

Good luck!!! Hope this helps.
Reply:Yes, they still might germinate.


Thanks for letting me know the info was helpful.


Good luck...fingers crossed :) Report It

Reply:There's also a possibility that the seeds could have been carried by the rains further from where you planted them. Wouldn't it be a surprise to find them popping up where you didn't expect them?? Report It

Reply:yep you right bout cold and rain,,,if you happen to have planted them too deep,,the rain packed the dirt so hard ,,that they can not push thru,,,,also cool or cold weather makes the ground too cold for them to germinate,,,,,,the Zinnas and Cosmos seeds are way smaller than Cornflowers and etc,,,so they only did bout 1/8 inch of coverage,,,i sow mine on top of ground,,then press them in with a garden rake,,,i do not put dirt on em,,,,
Reply:If you kept the packet it should have some form of germination guarantee on it. Take the packet back to where you bought it anyway as if no one does the problem of duff seeds never come to light.
