crabapple

Water Crabapple trees when they are newly planted until they are established. This will usually take 1 to 2 growing seasons, after which a period of deep but infrequent irrigation is generally sufficient. Watering Crabapple trees after they are established is best done once every 7-14 days during spring and early summer, and every 4-7 days during summer droughts or periods of extreme heat. The amount of water should be enough to moisten the top 12 inches of the soil and saturate the root zone. A soaker hose works well for this purpose. It is best to water in the early morning or evening to minimize water evaporation.

Crabapple (Malus 'Cardinal') is a deciduous plant species that benefits from full sun, receiving at least 6 hours of direct sunlight per day for best growth. It will tolerate partial shade, but flower production may be reduced in shadier conditions. In areas with hot summers, dappled or partial shade may be preferred to prevent sunburn. It can tolerate temperature extremes of -40 degrees Fahrenheit during winter dormancy, and as high as 115 degrees Fahrenheit during summer extremes.

Crabapple (Malus 'Cardinal') should be pruned in late winter or early spring before or shortly after the tree begins to bloom. Pruning should focus on removing dead, diseased and/or crowded branches, crossing branches, and any suckers coming from the trunk. Additionally, any dead leaves should be stripped away with the pruning. Pruning too heavily can be damaging to the plant, so it is generally recommended to lightly prune the plant in order to keep its desired shape and structure. Prior to beginning the pruning process, it is important to inspect the tree for any areas of dead or diseased branches that may need to be removed so that the tree can remain healthy.
