RADISH , Raphanus sativus (nat. See also:order See also:Cruciferae), in See also:botany, a fleshy-rooted See also:annual, unknown in the See also:wild See also:state. Some varieties of the wild radish, R. Raphanistrum, however, met with on the Mediterranean coasts, come so near to it as to suggest that it may possibly be a cultivated See also:race of the same See also:species. It is very popular as a raw See also:salad. There are-See also:RADIUM 807
two See also:principal forms, the spindle-rooted and the See also:turnip-rooted.
The radish succeeds in any well-worked not too heavy See also:garden See also:soil, but requires a warm, sheltered situation. The See also:seed is generally sown broadcast, in beds 4 to 5 ft. wide, with alleys between, the beds requiring to be netted over to protect them from birds. The earliest See also:crop may be sown about the See also:middle of See also:December, the seed-beds being at once covered with See also:litter, which should not be removed till the See also:plants come up, and then only in the daytime, and when there is no See also:frost. If the crop succeeds, which depends on the state of the See also:weather, it will be in use about the beginning of See also: The roots become See also:fit for use during the autumn. For winter use they should be taken up before severe frost sets in, and stored in dry See also:sand. Radishes, like other fleshy roots, are attacked by See also:insects, the most dangerous being the larvae of several species of See also:fly, especially the radish fly (Anthomyia radicum). The most effectual means of destroying these is by watering the plants with a dilute See also:solution of carbolic See also:acid, or much diluted See also:gas-See also:water; or gas-See also:lime may be sprinkled along the rows.
Forcing.—To obtain early radishes a sowing in the See also:British Isles should be made about the beginning of November, and continued fortnightly till the middle or end of February; the crop will generally be fit for use about six weeks after sowing. The seed should be sown in See also:light See also:rich soil, 8 or 9 in. thick, on a moderate hotbed, or in a See also:pit with a temperature of from 55° to 65°. See also:Gentle waterings must be given, and See also:air admitted at every favourable opportunity; but the sashes must be protected at See also:night and in frosty weather with See also:straw mats or other materials. Some of these crops are often grown with forced potatoes. The best forcing sorts are See also:Wood's early See also:frame, and the early See also:rose globe, early See also:dwarf-See also:top See also:scarlet turnip, and early dwarf-top See also: Additional information and CommentsThere are no comments yet for this article.
