My first time for growing veges, i am volunteering at a charity, putting a lot of good stuff in the assigned garden bed, can i plant cucumbers now? What happens if i plant too early? Brisbane location.

It is a bit like going for a swim in winter compared to summer. It is a spring crop - not winter. It says plant from August - that is only 4 weeks away. There is a reason why you plant at a certain time - different plants need different temperatures to grow - to achieve the best results.

I am getting lots of flowers on my plant and they are turning into fruit, but die at about 2cm, why? How do I get more fruit, I only got 1 cucumber that grew to 10cm

This may be a bit late for this year but my best suggestion is that after one or two fruit (cucumbers) on each runner have set, pinch off the end of the runner. This means the plant puts its resources into the fruit instead of growing a longer runner. Cheers Arismac

The flower with no fruit is a male flower. The flower with a small cue is the female flower - if it is not pollinated then it dies. You probably no bees (or more like very few of them) in your area. You might have to hand pollinate each day. Or plant some bee attracting flowers to encourage more bees to come to your area.

Plant some Basil and let it flower. Bees just love it and they will keep coming back for most of the summer and autumn. Solved my problem with all my Curcurbits (melons, cucumbers, pumpkins, etc)

I will try that. Over the summer I had about 20 sun jewel flowers plants in my garden, with hundreds if not thousands of flower heads - saw about two bees all summer. The bee population has taken a massive hit world wide I hear.

If you have TRUE high humidity: humidex above 95% consistently -- then you have a real issue. If you have a "created" high humidity situation: like a poorly ventilated greenhouse; then correcting the ventilation will fix things. You can create an updraft by placing a screened window/door very close to ground level (or the lowest level that opens to fresh air) and then furthest and highest away from this point another screened window (on the ceiling/roof, or very high on the wall). So if you have a door on the North/East Bottom. the window goes on the South/West Top. When both of the windows are open, you should get a nice updraft that will whisk away all your humidity. It is best to situate the ground level door/window in a shady spot -- because this will be cooler air, and as this comes in it will force the hot/humid air up and out. There are also green house fans that can be installed (but if you do your updraft correctly you will probably not need one) ; and if you are fully indoors even a dehumidifier might work. If you are in a garden setting like the situation above; I think perhaps the cucumber created a roof that was helping hold in the moisture. In this case prune the cucumber to increase airflow. Things like fences can hold moisture; for example if you have a garden between two houses and there is a wood picket fence; this could impede the flow of air, and cause humidity to build up. The answer will ALMOST always be to increase air flow. If this is a true climate issue then you should select what you are growing with care, choosing plants that can tolerate high humidity; and still trying to situate your plants/garden in such a way that air flows freely. I have an allotment, that has "dense" fencing on two sides (I am in the back corner) and I can feel that I have an extra humid situation. I have found that runner beans do well; once they climb higher than fence level, they get a lot of air flow and do nicely. As far a hydroponics; I am not well versed enough to even begin guessing at the issues that may exist in these environments. Just remember that even when the humidex is NOT high, plants still need the airflow to move what they have transpired away from their leaves.
