tomato rot

[shianne]

can anyone let me know why my tomatoes are going brown at the flower end before they ripen, they are grown in Levington Gro bags in my green house, and fed according to Miracle gro instructions. we had this problem last year, so over winter we washed green house out with Jeyes Fluid, to no avail.

Blossom end rot is caused by a lack of calcium in the developing fruit. This may be due to a lack of calcium uptake from the soil or to extreme fluctuations in water supply. Incidence of blossom-end rot is also increased where there is a low ratio of calcium to certain other nutrients such as potassium and nitrogen.
Although the most desirable calcium levels for preventing blossom-end rot have not been determined, the application of lime to the soil  known to be low in calcium has helped to prevent the disease.  Since blossom-end rot is so closely related to extremes in the water supply, an important aid in control is to regulate moisture supply in the soil.

Additionally, after tomatoes are planted, good results have been obtained by spraying foliage and stems with anhydrous calcium chloride  four times on a weekly schedule beginning when the second forms, or when symptoms first appear. Follow the recommended dosage... Good luck!
