A had planted both sides of the garden one last time after she moved to her own place, then started a garden at her house last year. Last year E and I decided to leave one side to go fallow and I planted pickling cucumbers the other side and started up some herbs on that side because the other area was getting taken over by the chives and lemon balm. What we discovered is happening is that the one side really didn't go fallow per say, it's being overtaken by the strawberries, chives and surprisingly enough spearmint which had almost gotten wiped out by the lemon balm. The spearmint and strawberries are even moving outside of the boxes around that plot.
Last year the other side did OK although the weather was weird so my cucumbers didn't grow well and I worried about the herbs. This year everything is doing really well, so well in fact that the raspberries are starting to spread into the garden plat. I'm still not sure what I'm going to do with the stray raspberries.
