Container potato companion plants
I have planted various types of potatos in wooden crate containers on my back patio. I am wondering how large the above ground plant will be. Can I make use of the upper part of the containers to grow something without a huge root system, maybe something that can be grown on a trellis like beans or cucumbers? I wasn't sure if the potato foliage would choke out the seedlings or if the roots would disrupt the potato formation.
You may be able to combine potatoes with a trellised vining crop such as cucumbers or beans. A lot depends on the size of the container. Basically the plants need just as much space in the container as they would growing in ground.
