Malus × zumi (or Malus zumi) is a naturally occurring hybrid species of crabapple in the family Rosaceae, native to Japan, and a garden escapee in the US state of Ohio. Its parents are Manchurian crab apple Malus mandshurica and Siebold's crabapple Malus sieboldii. It is used as a salt‑tolerant rootstock for apples, Malus domestica, as it can survive NaCl concentrations up to 0.6%. A number of ornamental cultivars are available, including 'Golden Hornet' and 'Professor Sprenger'.
The Japanese flowering crabapple has good resistance to disease and is generally not susceptible to illnesses. In terms of care, this plant is fairly low-maintenance. When grown outdoors it needs only minimal watering, and larger specimens typically do not require pruning. Smaller plants, however, should be pruned after they finish blooming. The Japanese flowering crabapple is suitable for anyone with an outdoor area, such as a garden or a deck, and does not demand extensive gardening experience.
How to keep Malus Zumi.
Light
The Japanese flowering crabapple comes from open spaces, like bright meadows and the peripheries of forests, where lots of light is available. It flourishes in Full Sun yet can also withstand Partial Sun, showing good adaptability to differing levels of sunlight.
Temperature
Japanese flowering crabapple shows strong adaptability to a wide range of climates, from scorching summers to cold winters. However, it still has a preferred temperature range for healthy growth. If temperatures become too high, the plant is vulnerable to heat and humidity stress, which can lead to its death. In regions where temperatures near the lower limit of its cold tolerance, it's important to apply insulation measures to protect the plant.
Fertilizer
The timing for fertilizing Japanese flowering crabapple is significant. Apply fertilizer beginning in the early spring and continue monthly until the early summer. The nutrients from the fertilizer assist in producing beautiful flowers and supply energy during periods of dormancy and active growth.
