This is not recommended. A light soil mix placed where it is surrounded by heavy soil too often results in trapped water, suffocated roots, and eventually a dead plant. Planting depth is important. Deep planting results in suffocated roots while shallow planting causes root stress from the more extreme temperature and moisture fluctuations in shallow soil. Refer to Purdue publication HO-100 for recommended planting depths when planting in heavy or sandy soils.
Problems can result from failure to spread roots of container grown plants.
Such plants often have roots that are coiled around the inside of the pot. Gently uncoil and spread the roots apart before planting. If this is not done, circling roots can eventually girdle or strangle the trunk as the roots increase in diameter with growth. Always remove twine, rope, or wire from the trunk at planting time to prevent strangulation of the tree as it grows. Improper watering .
