I'm sure it would, in the right sized pot. A good quality potting mix, with plenty of compost added to it, and some coir peat to help moisture retention. But what are you growing with your sweetcorn? The cucumbers could grow around and up the corn.

When the corn get big enough i was thinking of running beans up them.

Try growing on a trellis. An inverted V or even a vertical one. I'm trying a vertical one at the moment. Pumpkins and watermelons take up so much room. Best to decide what you are going to plant and where before you start planting. Give each the required area to produce a good crop.

Hi, I've just moved to Cocos Keeling Islands and have heard it is difficult to grow any fruit or veg here. Any advice on what to plant and when, how to improve soil conditions etc. would be appreciated as fresh food options are costly and not reliable. TIA

This is just a generic answer, not specific to the Cocos Keeling Islands. Any where the soil conditions or climate are considered poor, I would suggest raised garden beds filled with a good soil blend and organic matter. If the soil is unavailable, then a good potting mix (without moisture retention) and organic matter/compost will be fine. Then just grow what you want according to your climate.

Improving soil condition is about adding good soil if possible or adding organic matter - compost, manures, plant residue, grass clippings, veggie scraps etc to the soil and letting it all decompose - could take a few months. As for what to plant ask the locals what grows and what doesn't. I assume it is hot and wet so that rules a lot of things out. Look around and see what grows and have a go.

Why are my cucumber plants not making a cucumber, only flowers?
03 May 17, John (Australia - temperate climate)
Cucumbers often produce male flowers early in the season before they start to produce female (cucumber) flowers. The male flowers have a longer stem and do not have the unformed cucumber at the base of the flower. I'd say, give them a bit more time.

Hi, I am planning to move to Mount Victoria up in the Blue Mountains and was wondering if cucumber can grow in the cooler climate? Thanks!

You should be able to grow cucumbers successfully at Mt Victoria even with a longer winter as you get hot summers. Plant the seeds indoors in September in egg carton cells ready for transplanting into the garden in October. Plant the carton cell as well, it will rot. You can plant seed up until mid December. Choose a warm spot with good air circulation to reduce mildew problems. Growing them on a trellis is also beneficial.

The rules of companion planting indicate that cucumbers and tomatoes/potatoes should not be planted in close proximity to one another. Let's consider what companion planting is all about first. 1. Companion planting is about creating a diversity in the garden that reduces the chances of PESTs/disease wiping out your garden. So in CP you don't plant things that are prone to the same diseases or attract the same pests close together. In the case of cukes and tomatoes it is: fusarium wilt and powdery mildew. (there could be more things...but this is enough that you have violated one of CP rules). 2. CP is about nutrition in the soil -- that is, you would not plant two things in close proximity that both require heavy amount of any particular mineral/vitamin. So for example if both plants are heavy feeders of potassium -- clearly they would compete too heavily for this resource most likely all plants would not get enough potassium. Cucumbers are heavy feeders and require lots of nitrogen and potassium. Pale, yellowish leaves indicate nitrogen deficiency. Leaf bronzing is a sign of potassium deficiency. Potatoes LOVE potassium, and low levels of potassium cause hollow heart (the middle of the potatoes looks like it is rotting), further the potato plant needs ALL it's potassium at the early stages (BEFORE setting tubers). Potatoes are also HEAVY feeders. Tomatoes are HEAVY feeders. So CP says not to plant heavy feeders next to each other... they compete to much for nutrition. Ok, so now you know why CP says not to plant these plants next to each other. The question then becomes.... but CAN I still do it knowing about the wilt and mildew and potassium and general heavy feeding of all the plants.... SURE, BUT be sure to add lots of nutrition to the soil (compost/manure) add lots of potassium (before planting mainly) and be sure to top up the nutrition during the growing phases... so maybe add manure/compost before planting, mid season and again when fruit starts setting. Also all these plants LOVE water... and lots of it, and this to me, makes it convenient when watering, to have my water lovers all in one spot... that way I can just dump a 5 gallon bucket of water int he middle of them. Also, careful how you trellis the cucumber, you don't want to create a roof over the tomatoes/potatoes that will hold moisture and encourage the mildews.
