Butternut Squash Seeds

Hi I had a bumper crop of Butternut Squash this year but I'm thinking it was the record sun we got.

is it worth using the seeds from the ones I grew or is it best to buy another lot from a seller?

 

They could have crossed with marrows, courgettes, pumpkins and any other squash growing in the vicinity.

My local Wilko still have Butternut squash seeds for 10/30p packet.

 

oh right never knew that I was growing yellow courgette next to them so better not use them then
