Good afternoon, I work in the landscaping industry as a residential production manager. I have a question regarding a site I manage in new Albany. I want to provide as much information as I possibly can to help you understand the issue I'm dealing with. This site was completed last fall by our design build team, we have had massive amounts of drainage issues that has caused flooding in the taxus hedge row, our team excavated a trench (through clay) and we installed professional blend garden soil. About 1-2 feet of new soil. We then installed the taxus, but with the grade of the property all the run off goes to the taxus hedge and they have been sitting in water. I have finally installed enough drainage to keep water flowing past them, but the clay was creating a dam. I feel I'm in a better place with the water issue, but I'm trying to get roots to start moving and get them established. So my question, Is it safe to apply a liquid fertilizer to the Taxus hedge without causing damage? I have a product called "Grow In" (this is labeled for turf grasses like bent grass to help establishment). But my thought process is when plants are newly installed/ transplanted they do more surviving than thriving, while trying to set their roots ( perfect conditions) but I don't have these conditions, i have Taxus that were submerged in water, so would they absorb nutrients through their root system under such stress and conditions? Because they are not even pushing any root growth, and they have been in the ground for months. So would it be better to apply a liquid fertilizer to have instant absorption through a Foliar application to help the roots start moving? I did apply a product called sanctuary 3-4-4 to help them get established, about 2-4 weeks ago. I don't want to lose anymore taxus. We have replaced about 70 of them since install. I also just today applied a 24-0-12 fert I am no arborist, but this makes sense in my head, and this thought process could be completely wrong. But id love to hear your thoughts. Thank you.
