| If you have problems growing brassicas, you may be more successful with one of the new "Club Root Resistant" varieties, such as Cabbage Kilaton F1 Hybrid and Cauliflower Clapton F1 Hybrid, available from Thomson & Morgan. | Clubroot can be a big problem for brassica growers. Initial symptoms are stunted or sickly plants and the foliage may develop a purple-red tinge, and confirmation will be obtained by pulling up a plant and examining the roots. Infected roots are swollen and distorted, often producing either a single large club or a cluster of smaller swollen nodules resembling small dahlia tubers. Clubroot affects all members of the brassica family - cabbage, cauliflower, Chinese cabbage, broccoli, Brussels sprouts, kale, kohl rabi, swedes and turnips. It is easily transmitted. Just walking from an infected patch onto a clean patch of land can infect the soil and it can also travel on plants, so do not accept brassica seedlings where the source is not known to be clean. It is also almost impossible to eradicate, staying in the soil for up to nine years. But the good news is that, although no chemical controls are available nowadays, there are now some new "Club Root Resistant" varieties appearing on the market which, although not totally immune, offer a good chance of success and are worth a try if you have had problems! Varieties to look out for include: Cabbage Kilaton F1 Hybrid and Cauliflower Clapton F1 Hybrid, available from Thomson & Morgan, or Cabbage Kilaxy and Swede Invitation from Suttons Seeds. |
