Some plant species actually survive and grow better if planted in spring. Examples include beech, sassafras, sweetgum, sourwood, walnut, white oak, or others that have few, but large roots. Most plants that have many small fibrous roots can be transplanted with a high degree of success throughout the year. Most Ohio soils, however, are not well drained. They usually consist of silt and clay particles, and drainage is often less than desirable.
More air needs to reach the root system when soils drain poorly.
In these soil conditions, plants can be placed from 2 to 4 inches higher than they were during their growth in the nursery. The major reason plants do not survive transplanting is improper moisture, e.g., too little, too often, too much, or a combination. Balled and burlaped plant planted at original depth with watering depression. Balled and burlaped plant slightly raised above grade. Soils that remain wet for long periods of time after a rain or irrigation can be managed to prevent problems.
