Cages are held together by bending and crimping the ends of the wire around one of the vertical wires. Place the cages over the tomato plants shortly after planting. One plant inside each cage is recommended. For support, snip off the bottom ring of the cage and push the cage into the ground. It is highly advisable to support the cage with wooden or metal stakes to keep the cage from falling over later in the season.
Several conditions cause tomatoes to fail to set fruit.
Any one of these can cause poor fruit set, but combinations are even more damaging. Few, if any, large-fruited tomato varieties will set fruit during cool, cloudy weather. Most of this poor fruit set caused by cloudy weather conditions directly relates to improper pollination of the blooms. Tomato flowers are wind or mechanically pollinated, so gardeners don't have to have bees. Most insects are detected and controlled using a recommended insecticide.
