I planted it at the end of my vege garden, someone said I might be overwatering, as the sprinkler system got everything. I have trimmed it right back in the winter, ready for the next summer. My garden soil is composted filterpress, beautiful and black and it was placed over a few inches of cow manure. The worms are plentiful and fat. Any tips, ideas would be appreciated.
If you are getting lots of lush growth but no fruit you might have overdone it with the nitrogen in your soil and be lacking potash. Potash is essential for good fruit formation, and nitrogen is for lush growth. If you have a wood fire try adding the ash from it to the raspberry bed, otherwise a sprinkling of potash which you should be able to buy from a garden centre.
