Plants are trained so they initially grow vertically, being supported by poly twines attached to a plant support cable approximately 3m tall. When the plants grow until their growing tips reach near plant support cables they have to be lowered and leaned horizontally, and 102 only raised back to a height approximately 12cm tall, making sure that no fruits or leaves are touching the ground after plants are lowered. Tomato plants will require pruning every 3-4 days.
Lower leaf removal, de-suckering, de-flowering and, cluster pruning, are best done before leaning and lowering. The use of a fungicide to spray or paint unto open wounds on the stem after these activities is recommended.
The grower must maintain a good fruit to leaf ratio making sure there are enough leaves to manufacture sufficient food, leaves to support the transpiration process, and to provide …show more content…

It first appears as a sunken, brownish black spot 12 to 25mm in diameter on the blossom end of the fruit. These spots may gradually increase in size. Although BER itself causes only local injury, secondary organisms frequently invade the lesion and cause complete rotting of the fruit. It often occurs in rapidly developing fruit during periods of hot, dry weather and tends to have the greatest impact on the earliest maturing fruit. BER is caused by a calcium deficiency that is related to wide fluctuations in available moisture. To prevent BER, maintain a steady rate of plant growth without stress. A consistent and ample supply of moisture can reduce the problem by helping to maintain a steady flow of calcium from the growing medium to the fruit. Mulching also will help by conserving soil moisture. BER is more serious when an excess of nitrogen fertiliser has been applied. If BER occurs, remove the affected fruit so that later-maturing fruit will develop normally. Blossom End Rot. (Sources: The Garden of Eaden.
