Malus spp., or flowering crabapple, is a popular ornamental tree prized for its blossoms but prone to pests and diseases, including fire blight, scab, cedar-apple rust, and aphids. To thrive, they should be planted in full sunlight with moist, well-drained, slightly acidic soil, and prefer regions with cold winters and cooler summers. They are moderately drought-tolerant once established and can tolerate a range of pH levels. Regular pruning to thin the crown and improve air circulation helps prevent disease. Most crabapples are grafted, so ensure the graft union stays above the soil line. Though somewhat messy due to fallen fruit, crabapples are well suited in a variety of conditions.
