A bulb casing encases a plant bulb and properly positions, feeds and protects the plant bulb, in a biodegradable casing including two joinable, substantially hemispheric cavity members, preferably having plant nutritional supplements on or in an inside surface adjacent to the bulb's outer surface and rodent repellent materials on or in the outside surface thereof. The plant nutritional supplements can be plant food, such as bone meal. Artificial rodent repellents such as mothball materials or biodegradable, non-toxic chemicals such as cayenne pepper can be used. Preferably, the hemispheric cavity members are formed out of biodegradable cardboard or cellulosic material, such as moldable paper pulp or starch resins, so that the casings will degrade in the ground as the bulb grows to a plant. The two hemispheric cavity members are provided preferably each on a flat piece of material, which is scored at its mid point to form a hinge, so that the two hemispheric cavity members converge to form a substantially spherical casing around the plant bulb. A loose latch joint closes the bulb casing around the plant bulb. On the bottom of the bulb casing are provided extendible leg portions, so that the bulb casing can be self-standing within the hole in the ground in which the plant bulb is to be planted.
