Compacted soil with poor aeration will lead to poor root growth, which in turn affects leaf growth. When planting coleus, choose soil that is well-aerated and has good drainage.
4. Improper Fertilization
Too much or too little fertilizer will affect the growth of coleus. Excessive fertilization can cause leaves to turn yellow and fall off, while too little fertilizer will lead to slow plant growth. Fertilize reasonably according to the growth stage and needs of the coleus.
