Greetings,
A quick beginner question; What kinds of crop plants need to be pollinated? Also; do all crop plants need to be pollinated or just certain kinds?
Thank you

Generally, any crop plant that produces a fruit needs to be pollinated. Some require pollen from another plant, while others self pollinate.

That being said, some varieties are parthenocarpic. They produce fruits without pollination. But that's not the general norm.

On my homestead, bananas and pineapples produce fruit without pollination. I also grow parthenocarpic cucumbers so that I can have cucumbers that are grown in a screened shelter that protects them from pickleworm moth. No pollination required.

There are crops that are not fruits, thus no pollination is required to produce them. Examples: Kohlrabi. Rutabagas. Beets. Turnips. Onions. Broccoli.Ccauliflower. Cabbage. Anything leafy. It's a long list.

And to make things even more complicated, many of the varieties that are called "self-fertile" will produce more fruit if there is a pollinator around.
 
Listen. That's my theme music. That's how I know I'm a super hero. That, and this tiny ad told me:
