Questions and Answers / Cherry Tomatoes dying prematurely
« on: January 14, 2019, 11:39:26 am »
I grow the same tomatoes in Earthboxes every year. I follow the instructions exactly. I plant them in my pool area, under a screened cage; the plants row  grow very large, I believe because the light is filtered. But the plants have always been healthy. This year the Husky Cherry Red tomatoes are dying from the bottom up, inside out. They are planted in the same box and in the same spot as last year. Watering is constant with the AWS. there is no evidence of an insect problem; I spray w Safer road approx every 2 weeks.T he only difference is that this year I am using the snack 1 tsp. of ammonium calcium nitrate 15.5-0-0 weekly. The tomatoes on either side are thriving as usual. So my questions:
1. Why are these plants dying? Is it the snack? Are the plants growing too rapidly because of the snack? If it is so, why are the plants next to them thriving?
2. Is the ammonium calcium nitrate 15.5-0-0 the correct snack? I saw this stuff on a vireo in the forums
3. Should I replant? Should I use a replant kit as usual? Should I start fresh with an empty box and new potting soil? I planted these tomatoes the first week of November
4. Any other guidance?
Photos attached problem box is in the middle
THANKS for any help.

Questions and Answers / More snack questions
« on: November 07, 2018, 09:08:22 am »
This is my sixth season with Earthbox but my first using the snack
Two questions
1. I know I need the snack for my tomatoes because they are susceptible to BER. Is there a benefit to adding it to other boxes such as herbs and basil?
2. I had got into the habit of adding hydrated lime when my tomatoes were about 3 foot tall to prevent BER, rather than waiting to see if the BER occurred. It worked pretty well but not perfectly. Should I continue to do this in addition to the snack or will I be over fertilizing?
