How To Hand-Pollinate Plants
Increase plant production in your garden by learning how to hand-pollinate plants. Cucurbits (the family of plants including squash, cantaloupe, watermelon, pumpkins, and cucumber) are notorious for having pollination problems. Rather than having male and female parts in one flower, like a tomato plant does, cucurbits have separate male and female flowers on the same plant. That means pollen must be carried from one flower to another (male to female) in order for pollination to occur.
Here’s a little more in-depth description of how cucurbits flower: The first flowers on a cucurbit are male, and these may remain on the plant for about a day before falling off. Sometimes, this falling scares gardeners, especially those growing squash, because it seems like blooms are dropping and all is lost. But don’t fear, the female flowers come along soon, and they’re the ones that produce fruit. Female flowers show up on the plant usually a week or two after the male flowers start showing. After that, there should be both male and female flowers on the plant at any given time while the plant’s still blooming.
There are a few ways to distinguish male flowers from female flowers. The easiest way is to look at where the stem meets the flower. On a female, this area will look like small fruit. Male flowers are typically shorter, don’t show immature fruit, and often appear in clusters. Here are a few examples of male and female flowers on cucurbits.
