I have a tomato plant the size of a washing machine, and I need some suggestions. As you can see, lots of foliar growth, but very little in the way of fruits yet. I really, really wish I remembered what variety this was. It could be arkansas traveller, purple cherokee or black brandywine. I haven't pulled any fruits off of it yet, but some of my housemates may have. So. What do I need to do to it? Pruning? A lot? Side dress it? Is there a suitable organic phosphate type fertilizer to encourage more fruiting?
