Most malus species prefer full sun and well-drained, slightly acidic soils. Begin by preparing the planting area, ensuring it provides adequate light and rich, loamy soil. Dig a hole twice as wide as the root ball, place the malus plant in, and backfill, lightly packing soil to eliminate air pockets. Water thoroughly after planting. While these guidelines apply generally, each malus species may have specific requirements, understanding these is critical in fostering a healthy plant.
