The other type is temeperature controlled. If you imagine tiny golf balls filled with fertiliser which leach out from the 'dimples' as the temperature rises but if it's too cold retains the nurients as it contracts.
In my opinion the second type is better and can control release of fertiliser for up to 6 months!
My white onions that I was so impressed with last year have arrived so will be planted along with the yellow and red onions when I prepare the beds for them.
Thanks Vinny, which brand controlled release ferti do you go for?
