There are so many different ways to grow tomatoes. But, the latest idea I've found is ingenious if your tomatoes are looking tall, thin and floppy: you can grow tomatoes sideways to make them stronger.
It may sound a little strange at first because this method of growing tomatoes requires burying the tomato stem in a trench. Roots then grow from the buried leaf nodes, resulting in a stronger root system. It's the perfect solution to saving leggy or weak tomatoes, so you can still have a good harvest.
