wanting to manage space as much as possible, we have been interplanting the summer season crop where the cool season crops were growing. many of those cool season crop have now been harvested, but some continue to grow. since most of the cool season crops grow pretty low, the hot season crops are able to grow above them and then when it gets too warm for the cool season crops, we simple remove them and cultivate around the warm season crops. some examples.
part of this has been a bit of fun and experimentation. i wasn’t sure how growing in the other plants would affect the growth of the summer plantings, but so far they seem to be doing great. i have a control area, of tomatoes in beds that we never planted any cold season crops into, and they don’t seem any slower to develop!
