The Rural Voice, 1979-08, Page 44Gardening Research trials show wire cages beneficial for good quality and increased yields Research trials show that it is advan- tageous to put wire cages around your tomatoes, insteads of training them to a stake or letting the vines trail on the ground. Besides reducing the labor required for pruning and tying in the conventional staking method, there are other beneficial results. Fruit remains clean, and is generally of better quality. Yields of quality fruit can be increased as much as 30 per cent, and the tomatoes are generally larger. The incidence of sun scalding is reduced because no foliage is removed and fruit remains protected from the sun. Since the fruits do not touch the ground and air is allowed to circulate through the foliage, damage from diseases is also reduced. However, it may be necessary to water more often, because the additional foliage increases the transpiration rate (water loss) of the plant. CONSTRUCTION Ten -gauge 6" x 6" concrete reinforcing wire is generally most effective for wire cages. A 5 -foot roll is cut in half forming two 21/2 foot strips. The cut ends form the "legs", which are pushed into the soil. Four to five-foot sections are then cut off each strip, and rolled into a circular column, 20 inches high, and 15 to 20 inches in diameter.The columns are fastened by PG. 42 THE RURAL VOICE/AUGUST 1979 bending or looping the cut ends around the solid wire on the opposite end of the column. Cost is approximately 50 cents per cage for materials. Building the cage takes only about two minutes. PLACEMENT Plant the tomatoes. After the first cultivation, place the cages over the plants, and push the legs into the soil. Cages may be placed any time, while the plants are upright (12 to 15 inches tall). If poly- ethylene sleeves are to be placed over the cage, to hasten maturity, cages should be installed at planting time. Fertilizer side -dressing and granular herbicides can be applied without remov- ing the cages. Occasionally, a few large weeds, growing close to the plants, inside the cage, may require hand -pulling. SUITABLE VARIETIES It appears, from trials conducted at Vineland in 1972-73, that an intermediate - size plant is best suited for this type of culture. Extremely bushy plants, such as Heinz 1350, were difficult to pick because of the large amount of foliage. Extremely small plants, such as the New Yorker, did not appear to benefit greatly from the treatment. Varieties such as Veebrite, Basketvee, C28, Springset, Moira, Quinte, and Ottawa 78 should perform well under this system. INCREASED EARLINESS Using your cages as a support for a polyethylene cover, you can transform the cage into a miniature greenhouse or •• hot cap". This can reduce the chilling efte‘t of cool spring winds, and promote rapid early growth. Care must be taken, however, to insure that the temperatures are not excessive. On bright days, the "green- houses" should be ventilated by lifting the plastic. Be sure to remove this covering as soon as the plants are well-established, and the weather is warm.
