Some time ago I stated in ' The Gardener' that Mr Pettigrew of Cardiff Castle Gardens never thinned his Onions. On his recommendation the Onion crop here, in 1878, was treated in this way, with the most satisfactory results. At the end of the season the crop was a very heavy one for the size of the ground it occupied; and although many of the bulbs were growing in clusters of fives and sixes, all were of fair and useful size. In fact, many were above the average in this respect, as we were awarded second prize at Cardiff amongst over a score of competitors, and the bulbs were all selected from one un-thinned row. For little labour and a heavy crop this plan may be highly recommended. J. Mum.
