On Tue, 30 May 2017 10:49:49 +0100, "Bertie Doe" Meanwhile back on planet earth, a quick call to a local farm supplier; they have "Copper Mixture" made by Vitax at £3.74p for 175g "Sufficient to make 9 litres". It doesn't state Chris, whether it's c sulphate or oxychloride. "contain copper, manganese and zinc". .Amazon do it, at twice the price of course: .http://tinyurl.com/ya2gsppl But Vitax are marketing it as a trace element fertiliser, but I suspect that's just to get around the regulations, a bit like Root-Out is advertised as a compost accelerator rather than a herbicide The best compost accelerator, by a country mile is Yarrow. It thrives in the grass roadside verges, that have been regularly mown. The fern-like leaves are instantly recognisable. You can buy the seed, pick leaves at 4", a heaped tablespoonful per wheelbarrow of weeds/grass :- https://tedmanzer.com/2012/06/10/yar...edicinal-herb/ snip David, it may be of interest as it includes fruit as well as potato protection. Chris, if Bordeaux is a mix of copper and lime, the local supplier also has "garden lime" 3.5 Kg at £3.98 (inc) and 20 Kg at £9.98 inc. Should I sprinkle lime on soil or mix with the copper and spray on potato leaves? TIA Question: is it truly hydrated lime, aka slaked lime, or is it ground limestone? The latter is frequently advertised and sold as 'garden lime' because hydrated lime needs to be handled a little carefully, especially so that it doesn't get into your eyes. Suppliers these days are very H&S conscious, and won't risk selling anything remotely hazardous to the general public for fear of somebody misusing it and the supplier being sued. Hence proper hydrated lime is no longer available in garden centres, but only through builders merchants. snip Another call to the farm supplier - no it's not hydrated/slaked lime and is in granular form. These should be forked into the ground. It does not state that it's water soluble. If I can't get hold of the slaked, I'll spray with Vitax and dig in the ground lime. I also need to move brassicas from g/house to allotment. These will also benefit from a dose of lime. Going off topic a bit. In the past you used to be able to get calcified seaweed but this seems to have gone off the market in the last few years. |
