Seedless watermelons are extremely dependent on pollinators for yield. A pollinator, typically a bee, has to first visit a male flower from a pollinizer plant (pollen donor) and then deposit the pollen on a female flower from the seedless plant.

Soil testing is a valuable tool for assessing what nutrients are present in soils and the amount of[Read More…]
