Can anyone please tell me about these squashes

You can still eat it @BobMcFish and see if it ripens a bit further if you want. When they aren't fully ripe they don't have the same flavour but are perfectly edible, more like a courgette/marrow. It may be hard to tell which stage it is at until you cut into it.

 

@Thevictorian great! Thank you for this advice. Much appreciated

 

All of the curcubrit family (courgettes, pumpkin squash cucumbers etc) cross pollinated very readily, so it's not unusual to get variation in the fruits. The seed companies have to take special measures to keep their seed strains true to type, but sometimes the odd bee gets through. If you grow in an open situation, as most of us do, then many pollinators will travel up to 3miles in a day, so any other pollen may set your flowers and cause variation in the resulting fruit. As already said I'm sure it will be fine to eat.
That said I do recall an instance of some courgette seed that were producing very bitter, dare I say even slightly poisonous fruit. I don't remember all the detail now but someone on here will.

It can make you very ill when it happens. The advice is when you pick the first fruit of a plant, put your tongue to the flower end of it. If it has the bitterness, you'll notice immediately. If you can detect nothing unpleasant, then it's fine and so is the rest of the plant.

 

Can you please advise? This fungus is spreading over its surface. I think I need to eat it soon. Do you think the internal flesh will still be ok? TIA

 

Yes - eat it very soon - just cut out the brown bits - it'll be obvious

 

You can always freeze the flesh if you don't have an immediate use for it.

 

@Stephen Southwest many thanks Stephen

 

@Escarpment Thank you Escarpment

 

It’s not that lovely orange colour so not as ripe but it looks and smells ok. Quite moist and no brown bits

 

Gourds for drying go completely mouldy before fully drying but you cant eat them. Bottle gourds and similar. Has anyone here tried growing those? Having a home made squash water bottle would be fun!

 

@Adam I Sounds a bit too advanced for me
