Just put in a vegetable garden. On one end of the garden, the soil is turning green. I reworked the garden to improve drainage but the north stays somewhat moist, causing the soil to develop a green coat. I don't think I will get the drainage any better. What can I do?

Since drainage is definitely an issue here that is causing algae to build up in the soil, you may want to consider putting in a raised garden bed instead. Alternatively, you could construct a berm to redirect the drainage to another area. These articles should help: https://www.gardeningknowhow.com/edible/vegetables/vgen/raised-vegetable-gardens.htm
