Fertilisers

I'm at risk of becoming Dave Thornton's groupie as I attended another lecture given by him on fertilisers on Monday night. It's a heavy subject but I'd recommend you attend such a talk if you get the chance so that you can better understand your plants needs. Again, I shall be divulging as much as I can about what I learnt over the coming weeks and months but for now it's important you get any fertilizers onto your beds at least 2 weeks before you plant or sow. A good compound fertiliser with equal NPK is as good as anything for now but you may want to consider applying extra nitrogen. Dave felt that we amateur gardeners don't pay enough attention to nitrogen depletion in the soil, as it's the one ingredient that gets leached out of the soil during winter and which is most easily taken up by plants. Plants requiring a lot of nitrogen will need much more than others....things like cabbages, brussels, celery and leeks. A surprising veg that also needs a lot of 'N' is beetroot.

Like I said, more on this subject soon. At the weekend we went away for a short break in Norfolk but whilst I was there I took the opportunity of visiting the garden of Trevor Last in Norwich. If Andrew Jones, Sherie Plumb and John Branham are (in no particular order) the Man Utd, Chelsea and Arsenal of veg showing then Trevor is the very highly respected Everton, always capable of getting a result. He specialises in long carrots, parsnips and celery these days. I was gratified to see that he wasn't that far advanced in his preparation, although his parsnips, growing under enviromesh and polythene covers were about an inch high. When we returned on Monday afternoon the first of my parsnips had pushed through the compost surface. His onions were on a par with mine but his leeks were probably an inch in diameter which is pretty awesome at this time of year.
