I have a young American filbert hazelnut plant in my front yard that was planted at the beginning of April this year that is having some issues and looks unhealthy. These problems include orange/brown leaves, soft branches, losing leaves, and it is not growing (it is only 18 inches tall right now). I planted this plant with another of the same species for cross pollination - the plants are 7 feet from each other in my front yard and get lots of sunlight during the day. The other plant is healthy and approximately 33 inches tall with lots of green leaves. It does have a few (less than 5) leaves that also have the orange/brown leaf issue, but its overwhelmingly healthy. Since planting in April, both plants have been watered deeply, roughly, once a week, it's possible I missed a few weeks earlier in the summer. However, in last 2 months they have been watered more frequently (3-4 times a week) and given them two doses of plant food using this product (https://aerogarden.com/accessories/plant-food/<personal data hidden>.html) (diluted for outdoor plants). In my Google searches before reaching out, it seemed like maybe the issue was a potassium deficiency in the soil so they were given plant food to try and correct the issue, but the struggling plant looks like its losing more and more leaves even with plant food and watering over the last two months. I'm not sure if I need to be more patient as the plant is recovering or if I need to take additional steps to help the plant make it. I'd also like to note that both plants have been in deer cages and I have not noticed damage from deer. I also havent noticed a bug infestation of any kind on the plants. Can you please help me figure out a course of action to help the struggling plant get become healthy?
