VEGETABLES Grow potatoes and thwart moles P otato growing success is possible with welldrained, deep, sandy loam containing plenty of humus, paired with cool, moist conditions. Yet, even in seemingly ideal growing conditions, potatoes are not always problem free, being susceptible to an astonishing number of setbacks. You can encounter Potato tower necessities early blight, late blight, mosaic virus, potato scab or blackleg. You might battle against cutworms, wireworms, moles or aphids. But here's a solution.

You will need 1 – 1,2m tall weldmesh fencing with sufficient gauge to retain its form, and last for a few years; wire cutters, some sort of twisty tie, cable ties or binding wire, straw or hay, pure manure-free compost, a water source and seed potatoes. Use the wire cutters to cut out a section of the fence to create a cylinder about 90cm in diameter. Use either twisty ties, binding wire or cable ties to tie the fence ends together. Use straw to create a nest at the bottom of the bin to both help keep in the compost, and to reduce water-loss due to evaporation. If you do it without the straw, use weldmesh with smaller holes to keep the compost from spilling out. The straw naturally supports itself up the sides as you spread it, leaving a large central area for the compost. Next, shovel in compost to a depth of about 30cm.
