Just read the article on fertilizing tomatoes. I use the Epsoma Tomato fertilizer and gave some to all the tomatoes when I planted them. The ones we planted in containers are setting fruit, but I am wondering if I should give them a bit more of the fertilizer now or wait a while since they are in containers? What do you think?

For container tomatoes, I would use a slow release fertilizer. Since they can't spread their roots out and continuous watering washes out fertilizer much faster, a slow release fertilizer makes sure they get ongoing nutrients. Slow release fertilizer is also good to keep the roots from burning from the fertilizer in the container.
