Growing giant marrows, advice wanted

Postby Mouse2 » Fri Jul 13, 2018 1:11 pm

I want to have a serious contender for the heaviest marrow class in our village show this year, having failed dismally in the past.
(Ok, I could hollow one out and fill it with concrete, but I am too honest for that, :lol: )

This year, I did the first basic essential by buying some seed for a variety that actually has the potential to grow to a good size, supposedly, (Fatboy F1) and the claims seem valid, as in less than three weeks since baby fruits appeared, I already have marrows bigger than anything I have managed before.
I am only growing two pants, and am limiting each plant to just one marrow

The thing is, the show isn't until 9th September, and I am wondering if I have started too early. Are these fruits likely to stop growing and start rotting in that time? How long before a show do the serious growers allow from baby fruit to show?

I would be really grateful for any expert advice :)

Snap, be most interested to hear what others have to suggest.

Everywhere I went this year the only plants I could get were Long Green Bush, the variety KG / DT Brown gave away last year which I had dismal success with

The danger when people start to believe their own publicity is that they often fall off their own ego.

At least travelling under the guise of the Pa Snip Enterprise gives me an excuse for appearing to be on another planet

Pa Snip, I sourced my marrow seeds online this year. They weren't expensive - I think I only paid three pounds something including postage. Like you, I had no success with Long Green Bush - my standard 'courgettes' grew bigger!

I would and did last year , I put straw under each marrow to keep them off the soil I also scattered slug pellets in the straw ,plenty of manure and liquid feed as well ,I limited each plant to one marrow but made sure the chosen one was growing well before removing others , saying this is no reason to think I'm an expert it's just what seemed right at the time , this year in growing pumpkins at least they are ok for soup

I hadn't thought of slug pellets, Robo - that might be a good idea, especially when the dry weather ends!

Due to lack of space, I am trying to grow a pumpkin plant up into a tree this year. :D
If I actually succeed in producing any, the grandchildren will probably claim them for Halloween.

I think I have found the answer to my own question - or part of it, at least - here:
http://www.giantveg.co.uk/index.php/en/ ... from-seeds

That giant-grower pollinated his marrows 45 days before the show, letting the plants get very large first.
I also found another site where the grower didn't allow pollination until mid-July. Based on those timings, I definitely started mine off too soon.

Now, a dilemma - to remove the existing large marrow on one of my two plants and let another flower pollinate (hedging my bets by letting the one on the other plant grow on), but risking that the plant has already put too much of its energy into that first marrow, or to leave things as they are for this year.

Difficult! As I have the 'spare', I will probably opt for the first option. Next year, I will hopefully remember to do things differently!

That's interesting Mouse, I wouldn't have thought you could get a giant one in so short a time. I think I would hedge my bets as you suggest and nurture the big one and have the other as back up.

Dear Mouse,
there is a book called growing giant veg by Bernard Salt; I think it is out of print so It may be hard to find. Whilst searching for a supplier I found that there are loads of youtube vids on the subject.
Regards Sally Wright.

Thanks, Sally. I will keep an eye out for that book when browsing second hand book stalks/shops.
