Tuh culture should be resorted to only from lack ofspace, or when no other method can be adopted (). For this system of culture, nympheas should be chosen that are moderate growers, yet free-flowering,and other miscellaneous aquatic plants. The tubsshould hold from 4 to 12 cubic feet of soil for nympheas,according to the variety, some being moderate growers,others vigorous and robust. The tubs may remainabove ground or sunken. If sunken during the warmweather, the roots are kept cooler, and this is desirable,especially if hardy kinds are grown. A great improve-ment over tubs is a concrete pool 4 or .5 feet in diametermade in the shape of a tub, and 2 feet deep. A circularform 4 or more feet in diameter should be made and theground then excavated 8 inches larger than the will allow a wall of concrete 4 inches thick.
