Is it okay to plant chicken cone trees outside the fence?

Very good. Sweetheart trees can be used not only for landscaping, but also for building sightseeing and picking gardens. They are also suitable for planting in home courtyards. Compared with apple tree species, chicken core fruit does not have obvious growth and development requirements, is not strict with water and fertilizer requirements, and has strong resistance to diseases and insect pests. So it's nice to be outside the walls.
