Where do I start! I've had a few failures this year, more than likely due to the cr*p weather we've had this year. Beetroot has been my biggest failure, despite bei g new seed, 3 direct sowings and 1 sowing in cells, they all failed, no growth at all and a good % just went to seed!
Courgettes, I grew 3 varieties and all had rotten ends before reaching maturity. In the past, I've just chucked them in and let them get on with it withput any care and had a glut every year?
Butternut squash.. I tried them for the first time this year and didn't get a single squash.. but flamin heck they don't half take up a lot of ground space, which I'm pretty short of in the first place!
Apples.. both my dwarf varieties of apple trees were decimated again this year, what with an ongoing battle with aphids & ants and no fruit to speak of, I've removed them from the garden and I'll just buy fruit from the supermarket from now on!
