Many root knot nematodes have been found in association with caladiums in Florida. Symptoms include discolored, decayed, galled or deformed roots and stunted growth. Control has been achieved with hot water treatments and nematocides.
3) p H - Often in the upper midwest we can have difficulties maintaining a lower pH, i.e. 6.0. If pH should rise above 7.0 caladium growth can be reduced and foliage
