hi katja sounds like you have sooty mould. how i get around this is to grow my cucumbers on a trellis. just a post at each end and string about 9 inches apart between the poles. clip the cucumber leaves to the string with a clothes peg. keep stringing until they reach a height of about 5ft. the air circulation reduces the amount of sooty mould.

Does anyone know if possums eat baby cucumbers? I have plants that have been flowering for 2 weeks or more, but I cannot see any sign of fruit maturing. (Melbourne Australia)

Hi john d, It is possbile that that is as big as the cucumber/zuchinni was going to get. It is best to pick these fruits when they are still rather small. I have heard that when a cucumber goes dark green and the little spike start to grow on them they are ready. With a zuchinni is is best to pick when they are around 15 cm or so for nice sweet fruit. Apparently with zuchinni you are supposed to be able to pierce it with your fingernail. Both of these fruit grow very fast so it is best to check them at least every day. We have had success growing these for the first time this year. Good luck and happy eating !! Jodie

H Katya, Your cucumbers sound like they have mould. I make some chamomile tea and when cooled, spray it directly onto the leaves. I also use it on tomatoes and zucchini. Works perfectly! I do it about every 10 days. Didn't know about it last year - wish i did!

I'm growing "Bush Champion" cucumbers and they are now starting to produce fruit, I've never grown cucumbers before and am wondering when is the best time to harvest them.

Hi Steph, I just planted the seedling from the tray to the ground. I was using seasol to develop its roo. I have heard the fertilisers are strong and tender plants like cucumber doesn't like it.

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.
