|Why do my cabbage split when growing?|
|Splitting is caused by the pressure of excessive water taken up after the heads are solid. Cutting the roots (spading on two sides of the plant) or breaking the roots (lifting and twisting the head to one side) can often reduce excessive splitting or bursting, but it also damages the plant and requires that the head be harvested relatively soon. Cabbage head splitting can be avoided by keeping the soil uniformly moist near harvest time. Splitting is seldom a problem with varieties maturing during cool weather.
