This year I will be growing tomatoes in large pots and I plan on using potting soil for this. Should I add a fertilizer to the soil when I plant them? If so, which of these is best: humus & manure, bone meal, lime? These are the only fertlizers that are available around here (other than Miracle Gro) so please don't suggest something not listed as I won't be able to get it.
Last year I had a problem with BER near the end of the season. I also wasn't able to get as many tomatoes as I should've and it took forever. I know the weather was partly responsible (tons of rain in June; HOT, dry weather in July and August) and I was never able to figure out when the plants needed water. I also think the fertilizer I was using (Miracle Gro) had to much nitrogen.
