Why do my cucumber plants keep dying as seedlings. I'm lucky to keep one alive this year where as last year i couldn't give enough cucumbers away. They just seem to wilt and shrivel up. Any suggestions?

I've had cucumber seedliings that germinated with quite abstract looking seed leaves, though further growth was slow but normal in appearance. I'm wondering whether cucumbers dislike fertiliser in the soil at germination. I've been told beans dislike it at germination as well. Does anyone know about this or can offer any advice?

An organic farmer handed me an old cucumber of his and said I could use it to grow my own. Being completely new to this I just dug a small hole and buried it. Should I have taken out the seeds and dried them or do you think this will work?

We have successfully grown long cucumbers with over 2 doz picked in last month or so. But all of a sudden, we have these small black crawling insects attacking our bushes which are growing on a trelis. Any thoughts please

Hi Jenny, Cucumbers have male flowers and female flowers. (females have a mini cucumber behind the flower. Sometimes the bees are too few to get the pollen from the male flowers to the female flowers, so you can use a little paintbrush to take pollen from the male flowers over to the female flowers. If you don't yet have female flowers then wait a bit - the male flowers seem to come first. Applying a soluble complete fertilser with potassium seems to help bring on female flowers - or maybe this is coincidence.

Our cucumbers have been on the vine sometime and have very pale skin and when cut are very mushy inside and have very few seeds. What's wrong?

Hi! Jan, John and every cucumber grower. We all make mistakes and I'm no exception.Gee have i learn't. Jan if you look at the mix I suggested to Steve the same applies to your problem,possibly you also need to add lime if the ( ph) of your soil is below 6.8 you need 6.5 to 7 to grow good cucumbers follow this and you will have sweet cucumbers. John I would like to suggest you do the same as i suggested to Steve,also forget pots and grow in one or those green shopping bags they take 25Ltrs of potting mix and you can grow 2 cucumbers in this they also breath The mix needs to be kept damp not wet. also spray with white oil when they are young (natural) and stops most pests and fungus.all the best

I had two cucumbers plants growing in pots both produced a good size cucumber with other smaller ones growing as the larger cucumbers started to ripen the leaves on both plants stated to dry out and turned pale I've lost one plant which produced one large cucumber tasted great the other is going down the same path the 1 cucumber also tasted great why did my plants die or are dieing ? thanks

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.
