Where can I find smooth gourds similar to the one you show as a water bottle? In Mexico we used to cut one in half lengthwise to use as a water dipper.
Ebay is an excellent source for dried gourds.

I have tried many times & multiple ways to get fancy gourd seeds to germinate, eg. Birdhouse gourds, lg round gourds. I can't get them to germinate!! I have even sanded down the seeds to try & make it easier for them to germinate-but no luck!! I have been able to grow the lg warty pumpkin like gourds, however that is it. There are many kinds of these fancy lg gourds that I would love to grow, dry & paint etc. Can you help me?? Thankyou & happy growing!!
Soaking your gourd seeds overnight in water prior to planting will help increase germination. Sometimes gourds take much longer to germinate that the suggested time table in the packet. My last batch of snake gourds took two months to germinate because the night temperatures were too cold. Don't get too discouraged. Soil temperature and planting depth are important considerations. Gourds transplant well so you can start them in small pots and transplant when they are 3-4 inches tall. Be sure to use potting soil and not planter mix in the pots. Another option is to soak the seeds then place in moist but not soggy paper towel in a baggie (not sealed) and watch for germination, then transplant at the correct depth. I do this on my kitchen counter.
So your seeds are not germinating?

How do you clean out the gourd?
There are many ways to do this. If you want the gourd to be a birdhouse, you will cut a hole in the side, and pull out as much of the seed as possible. then let it dry. Alternatively, you can hang the gourd somewhere dry and dark until its fully dry, and the seeds will be able to rattle inside. For this method, there is no need to clean out the gourd.
I bought a bag of gourd seeds and they are going to come after the last frost this year. can I store them for next year? If so how? If not what should I do?
You can. Either a plastic bag, or my preference, a glass jar, will keep them fresh. Just keep them in a drawer, or a cool dark area until you are ready to plant.
