Shown is a portion of a two-metre vine, which produced over 50 perfect tomatoes where crushed egg shells had been placed in the hole at planting.

Often gardeners ask, “Why do my tomatoes develop blossom end rot?” A simple solution to this disappointing situation is to save your egg shells.

Although nitrogen, phosphorous, and potassium are important for healthy plants, calcium is also very essential, especially to produce a great tomato crop. As shown in the photo, by placing a container in a convenient place, egg shells for your garden can be easily “harvested”.
