Q.flowering transplanted shrimp plant has curling leaves
Why are all the leaves on my 16″ transplanted flowering shrimp plant curling this year? Soil is used but amended with fish emulsion and bone meal, and is kept moist. Do I need more perlite?
Not sure exactly what you mean by "transplanted." That word usually refers to a plant that has been growing in the ground, and has been dug up and moved to a new location -- is this what you mean? If so, the curling leaves could be a result of losing part of its roots, or being moved to a new location. Or do you mean it's a plant you bought from a nursery and removed from its pot and planted in your yard? It might be a disease such as verticulum wilt: https://www.gardeningknowhow.com/plant-problems/disease/verticillium-wilt-treatment.htm
Or do you mean - because of the way you refer to the soil and adding perlite - that it's in a container? It may be a cultural problem; this article brings up some good points: https://www.gardeningknowhow.com/plant-problems/environmental/what-causes-brown-edges-on-leaves-of-plant.htm
