how do i cross pollinate vegetable plants in my garden?

Answer 1

If you are trying to cross, say, a pumpkin with a watermelon, or squash with cucumber then you can't. The only plants that can cross pollinate are those that belong to the same species. If you are wanting to pollinate the flowers on you tomatoes or some other plant then you can use a soft thin paintbrush and just swirl it inside each flower or just leave it to the bees. After all, that's what we have our pollinating insects for.

Answer 2

You will need to "bag" the blossom and twist tie the open end to try and keep the blossom from being naturally pollinated after you have done the brush bit. You may also want to make notes about which bloom was pollinated by which other bloom.
Since some plants self pollinate, you might want to remove the pistils too.
I'd suggest a little googling......
good luck

Answer 3

The best is to take a fine paintbrush, and when the flower opens, take some pollen off the one plant and transfer it to the other plant. And vice versa. The problem that you might encounter is that bees and other insects also visit the flowers and will pollinate all that they visit. This might mix up your attempt.
