When too much rain comes, you want to have holes in containers you grow any plants, so water doesn't bother them. They are not aquatic plants - right? As you know, we had lot's of rain and floods in Poland. My house and garden was safe, but after few days of rain, my largest container where I planted lettuce and radishes looked like aquatic feature, not vegetable container. I wished there were holes. I emptied the water partially several times, but yesterday I gave up. No hope!
I decided to move my 2 months old lettuce to veggie beds to save it. Some radishes are still there, but majority was harvested.
Lesson learned. Make holes in your vegetable containers. No excuses.
