Q.I Bought One Blackberry Bush 4 Years Ago, and Still Doesn’t Blossom

Why doesn’t my blackberry bush blossom? It is very healthy and I bought from a reputable nursery. It continues to grow and spread, but still no blossoms, so no fruit.

The amount of nitrogen is too high, which results in more foliage growth and little to no blooming/fruiting. Add a phosphorus rich fertilizer or bone meal to the soil to encourage flowering, and in turn more fruiting, and this should help: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm
