Hi, I have the same problem. So far I have not found a definitive answer. Lack of water? Not last summer! Deficiency? Maybe, but cannot find any help there neither. Some pumkin have maybe one lump, others go to the cattle.

I am getting this mould or rust on my vegetables in my garden. It is causing many of the butternuts to die and the spinach to be spoiled. What could I do to prevent this?

try charcoal ash in your garden to prevent any diseases to the plants..

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?

Seeds need drying if being kept for planting in the future.

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.

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.
