I am quite amateur to any kind of gardening really but I decided to start some Brandywine tomato seeds this spring. our soil isn't great but we have periodically added rabbit poop and hay fertilizer as well as my own compost. It has been several months and the plants are not doing well. We had about twelve and all but maybe three died. The ones that remain are the ones that get the most sun throughout the day. Anyway, they haven't bloomed yet although the package said they would in about 90 days and most of the leaves are looking rather yellow. I try to give them a full watering every couple of days if it doesn't rain but the heat here in FL is brutal so I think they may need more than that. I am trying to grow things organically so I don't want to use anything that contains chemicals. I've already heard enough people say that is my problem but I know plenty of people grow tomatoes organically so there must be an alternative. Any advice would be greatly appreciated.
