Preparing potatoes for planting
Leafy sprouts show at the surface surprisingly quickly. I add potato fertiliser as I’m usually reusing potting mix that has already grown a previous crop. the clay soil was still at 10°C.So why does it matter? Seeds need specific temperatures for germination.
You’ll have much better results if you wait until the temperature is in the right range before sowing spring and summer crops. Beans, for example, need soil temperatures of 18-25°C for reliable germination. There are some soil warming techniques to speed things up. Try covering a garden bed with a cloche or a sheet of plastic to warm up the soil for a couple of weeks before planting. I’m using the polycarbonate sheets to warm up my soggiest garden bed. 18cm so I allow a tad over a handspan between seedlings that need to be 20cm apart. The width of my hand including the thumb is 10cm and that of my index finger is 1cm. From the tip of my index finger to the second joint is 5cm and my gumboot is 27cm long. Learn the measurements of your own hands and feet as a guide when sowing seeds or thinning out seedlings. When diluting fertiliser, it’s handy to know that a standard plastic bucket is 10 litres. For me, one handful is 75g, so I can work out how many handfuls of fertiliser or gypsum to spread.
