Hi Veronica! Where to start... First, the seeds on damp builders sand, are they in an enclosed container, or simply sitting on the top of the sand in an open container? If it's open and your refrigerator is frost-free, they are being kept too dry to germinate. If the container is enclosed, you should bury them under the damp sand about a quarter of an inch below the surface. Some people sprout their seeds on damp paper toweling, enclosed in either zip loc baggies or other enclosed containers. The temperature of the refrigerator also makes a difference. The lower the temperature, the longer the seeds hold before germinating. Some will sprout below forty degrees, many won't. Supposedly, germination begins to fall off at temps above 70F, but I see many sprout well up into the eighties.

I would plant them in the sand to about a quarter of an inch depth and make sure the sand is still damp and it is well covered to prevent it from drying out. Dry storage will hold the seeds longer without germination. Some believe drying them out will cause them to take even longer to germinate. If they haven't germinated by the time your outdoor temps fall into the sixties and seventies, remove the container from the refrigerator and place it where it will receive those temps. Hopefully, that will be indoors where you can keep an eye on them without the container filling full of water or something getting in and eating the seeds. Rodents LOVE rose seed. Good luck!

Thanks, Kim! They are in a bowl on top of the sand and covered with plastic wrap. Still nice and damp. I'll shove them deeper and perhaps take them out this week. Wait... I think I'll take some of them out and put them on the sink window sill. I'm there everyday at least twice. The others can stay till cooler weather. Fingers crossed....

You're welcome, Veronica! Hopefully, the sun doesn't shine directly on the window sill or it may over heat them. As long as the temps in the kitchen remain lower than the mid eighties, you should see something. When? Who knows? But SOMETHING. Mine are crossed with yours!

Yes, the sill is shaded all year and it should remain about 85 or below in the kitchen until next spring.
