This is horsetail. It is a plant that has survived 300 million years so it isn't easy or quick to get rid of it. Herbicide often isn't effective at killing roots. Persistence, improving drainage and luck seem to be involved in riding your garden of it. Here is an article: https://www.gardeningknowhow.com/edible/herbs/horsetail/horsetail-weed-control.htm. Here is another link. Note it was written in 2004. https://www.maine.gov/dacf/php/gotpests/weeds/factsheets/horsetail-swanson.pdf
