Do you know where I can get triamble pumpkin seeds from. I haven't seen them since koanga gardens had them.

surely it is not worth saving pumpkin seeds unless you have an heirloom variety? Most supermarket ones would be hybrids so they are unlikely to be true to the parent, and pumpkins are known to cross easily with cucumbers etc. Of course you would dry the seed if you are going to store them. Hardest thing with pumpkins is keeping the water up to them, they have so much foliage, they dry out easily.

Do seeds need to be dried before planting?

If l were to save the seeds from a pumpkin l bought from the supermarket will they be Hybrid variety? Do l have to dry the seeds out before planting them?

Pumpkins from a supermarket are likely to be hybrids . You do not need to dry the seeds before sowing but they will keep better until you want to use them, if you spread them out on some kitchen paper

Have you heard of a tribumple pumpkin or a name similar.

The name you want is Triamble. A grey pumpkin with deep grooves between usually three segments

Brett, Are you using bought seeds or saving seeds from pumpkins? If you have bought seeds, it might be worth contacting the supplier and telling them about your problem. Otherwise, if you saved seeds, see the answer to Jean's query.

Ray, your pumpkins are falling off early because they are not fertilised. You may need to go around with a paintbrush and transfer pollen from the male flowers to the female. Check the comment from Jaci to identify which is which.
