I may have made a school-girl error by sowing some pumpkins (large variety: Rocket)…
It seemed like a cool activity to do with the niece but now I’m
thinking that I don’t have the room or experience to make a success. 

Questions:

Can I grow in a large pot?
Should I let sprawl or try an upright support?
Is it just the main plant that needs the good earth/compost and the ‘vines’ can sprawl on grass/patio etc? 
Could I put in my poly greenhouse? 
Is it best to nurture just a couple of ‘fruits’?


Any tips gratefully received 🎃

    If you let them sprawl over grass they'll shade it out and you won't be able to cut it (which may or may not be a problem). I don't know how big a pot you'd need but my instinct is to go as big as possible if you can't plant in the ground and to limit the number of fruits as well.

    I have only ever grown them in the ground, in a hole with well rotted manure and my garden soil. They are very thirsty and hungry plants so you would need to be really on top of watering and feeding in a pot. When I plant them I put a upside down pop bottle in at the roots of the plant with the bottom cut off so I can fill the bottle with water and let it soak in under the soil.

    I leave mine to grow over the floor not upright as the pumpkins can get very heavy and I wouldn’t be able to support them. Yes the ‘vines’ are able to ‘sprawl’ over your grass/patio if you want.

    They need to be pollinated so keep that in mind in a green house.

    It depends what your doing with the pumpkins when your done. I eat mine so don’t mind the size. If your carving and want a big one I would limit to one or two pumpkins growing on each plant. Also I remove some that start later in the season as I know there won’t be time for them and it’s a waste of plant energy growing them.

    I also trim the shoot ends to stop them getting too big, they always want to make a massive plant.

    I find them quite a forgiving plant to grow, if you’ve already got them growing have a go, ‘nothing ventured’ and all that. 😀

    Hope this helps

    It is possible to grow pumpkins in a pot as small as 20L. I have grown Dill's Atlantic Giant successfully this way - I usually got 2 or 3 pumpkins with a combined weight of up to 6kg.

    However, this means that you will be tied to watering at least once every day (even when it rains) from mid June till October assuming that you plant in early June. You would also need to feed at least twice a week with half strength liquid feed.

    If you don't keep up this regime then the plant will get stressed and fail to set fruit and/or abort fruit even when it is the size of a child's football.

    If you increase the container size to 80-120L (black dust bin size) then it becomes a little bit easier.

    In all cases, you will need at least about a 2 square meter area for plant spread. This can be horizontal or vertical like a solar panel facing the sun at the most intense period.

    The pumpkin vines can be trained to follow any pattern you like. In tight spaces train the primary vine to follow a compressed Sine wave. Allow one or two secondary vines (side shoots) to grow in order to hedge your bets and remove all other secondary, tertiary etc vines in order to force the plant to form a fruit on the primary vine or close to it.

    Vine training can be done by tying down against a frame work (I used a metal frame from a bunk bed) or by sticks pushed into the ground to change the direction of growth.

    Pumpkin vines can produce roots at every leaf node so bury those points if possible if growing directly on the ground.

    It is not recommended to grow pumpkins inside small polytunnels unless conditions are not conducive to growing them outdoors in you local area.

    You are all fabulous- thank you for replying! 

    I am actually tempted to replace with small ones @B3

    Well I will see if the seedlings survive and I have a massive pot/bin so I will give it a go. I can put the daily watering in and if they sprawl onto the grass that will be ok. 

    If there is any success, I might shout out for tips again. Thank you 🎃

  • never grow pumpkins pots long term
     only fer transplant. pumpkin goal is
     taking over. 25ftx25ft for one plant
    is min space need most of time.

    Ok I have made the decision to give one a go! 

    I had an old recycling box and have filled it with well rotted manure and peat free compost. I’m going to use my potting bench to fashion a scramble frame (using a broken chair back and some planks of wood) and give it a chance! 

    Hopefully a success, and if not a learning exercise (one piece of learning will be not to grow the big ones. Maybe squash or mini gords next year?). 

    Keep you posted!

    Please post your pics of pumpkins/gords!

    🎉  🍾 

    Looks good to me. 

    Don’t forget you can make soup with the flesh you carve out.
