Using trees on vigorous rootstocks which will have a better chance of competing with the pathogens, or plants grown in large containers with a large root ball may also have a better chance of resisting replant disease. The extra time to cropping may be offset if new trees are planted a few years in advance of old trees finally falling over, furthermore, if the old orchard was grubbed— i.e. trees were healthy when removed, it is unlikely that replant disease would be a problem as pathogen levels may never have been high. The malady is worse where trees have died in situ-pathogens are likely to have contributed to the death and therefore be at a higher level in the soil.
