V.O. Porter, Erath County horticulturalist, described how he started tomatoes in the 1920s: “On a sunny site, south of building, a wood frame is filled with two-thirds full of a half and half mixture of rotted barnyard manure and sandy leaf mold. Boiling water is poured on the bed to sterilize the soil. Tomato seeds are started in February, covering the bed on cold nights.”
