Tomato tapping is the unconventional yet highly effective trick gardeners across the US are using this summer to guarantee a bigger, healthier crop of fruit.

During extreme weather, gardeners can often face failing plants, or malformed, weak fruits. The problem comes down to pollination, or lack thereof. Tomatoes are self-pollinating plants, however, for successful pollination to occur, the pollen must travel down to the ovum.
