Most varieties of apple cucumber are ripe when the greenish tinge has gone and they are a clear white. When they are overripe they go yellowish and are often bitter. This would apply to most apple cucumbers but there are some more recent varieties available that are green when they are ripe and some that are a golden, almost brown colour. Trust this helps.

Hi, I have apple cucumbers growing vigorously and with heaps of male flowers but no female flowers. What can I do please

I don't know of anything that will induce cucumbers, pumpkins, squash, etc to produce female flowers. Male flowers are always produced first but it is very frustrating. Female flowers generally appear as the season becomes consistently warmer. Trust this helps.

You can encourage pumpkins to put out more female flowers by snipping the growing end off after about 1.5 to 2m of vine. This made side shoots, which tend to make more females.

Could you please tell me when to plant Suyo Long Cucumber in Brisbane, should i put in jiffy pots to start or straight in ground where they are to grow.
05 Feb 17, John (Australia - temperate climate)
Direct sowing is always the best but Jiffy pots are OK. (They do not like root disturbance that can occur with transplanting from trays). They don't like frost but that shouldn't be a problem in Brisbane and as they are very mildew susceptible they don't like overhead watering. Good air circulation and ground watering are good ways to reduce mildew problems. Trust this helps.

How do you tell the difference between a female and male flower
28 Jan 17, John (Australia - temperate climate)
On all cucurbits which include cucumbers, melons, squash, pumpkins and zucchinis the female flower has a small fruit behind the flower. the male flowers, which contain pollen, do not and are generally on longer thinner stems. If the female flower is pollinated (fertilised) by pollen from the male flower the fruit will continue to develop to maturity

My cucumbers have flowers and start to develop fruit and then when very small go yellow and die.

Your cucumbers havent been properly pollinated. I suggest you get a small paintbrush and pollinate them by taking some pollen from the male flower and applying it to the female flower.I use this method with pumpkins and watermelon too

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.
