Hi, I live in Polokwane, Limpopo Province, so it is quit hot around here. Can I plant English Cucumbers in direct sunlight or can I plant it in a greenhouse with 40 persent sun troughlet, what kind of insectisides do I use? Can I plant it in pots of about 30cm high and 20 cm wide, then spaced to your specs or must it go directly in the ground?

My cucumbers are HUGE and yellow, I'm almost convinced that they are something entirley different. They have been planted too close together as I only have a small space, which I'm geussing may be the yellow, but I cant understand the why they are so big.

I am a learner gardner growing Lebanese Cucumbers for the first time. We have had lots of rain and some of the leaves are getting yellow marks on them. Is that a fungus or mould if so how do I get rid of it?

I am growing apple cues and on the same vines they are big and white and some small ( golfball size) and yellow so how can they be overripe? I have been juicing the yellow ones and they don't seem to be bitter, I have about 4 vines and they are all doing the same thing, some small and yellow are in shade some in sun, some big and white are hanging in sun in rosé bushes and on trellis covered by leaves, all deep watered nearly every day. It is a puzzle.......

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.
