Beans, Peas and Courgettes

Each year I prepare the soil well when I plant my courgettes. However, the first six or so emerging courgettes go yellow at flower end and don’t grow any further. Most courgettes after this are okay. What am I doing wrong?

I would like to know why the zucchini and pumpkin plants we grow produce an abundance of male flowers and very few female flowers. How can I improve this ratio?

I planted pea seed late September but the plants are only about 20cms tall. How can I give them a boost now and what do I need to do next season to get peas for Christmas dinner?

My snow peas went brown and dried before they had chance to produce a crop. They had plenty of water and there was no possibility of them coming into contact with weed killer etc. Why did this happen?

My runner beans usually grow well. This year I did nothing different and the beans grew vigorously and had many flowers, but very few set. They were well watered and in a very warm position. What went wrong?

This is my first year growing zucchini plants. I have raised my plants from seed and the plants are flowering well, however the flowers are not turning to zucchinis but instead are just falling from the plant. Why is this happening and what can I do to ensure zucchinis grow?

For the second year in a row, I’ve unsuccessfully tried to grow courgettes. They grow to about 5cms in length then the base of it burgeons out into a large bulb shape, then the remaining thin part of the courgette turns bright yellow. What am I doing wrong?
