What Vegetables Will Cross Pollinate with Each Other?
Cross-pollination occurs when pollen from one plant fertilizes the ovules of a different plant of the same species. This can result in the production of hybrid seeds, which can exhibit traits from both parent plants. In the case of vegetables, cross-pollination can impact the quality and yield of your harvest.
Which vegetables can cross-pollinate?
- Cruciferous vegetables: broccoli, cauliflower, cabbage, Brussels sprouts, kale, and collard greens
- Cucurbits: cucumbers, squash, pumpkins, melons, and watermelon
- Alliums: onions, garlic, leeks, shallots, and chives
- Other vegetables: carrots, celery, parsnips, parsley, and dill
How to prevent cross-pollination
To prevent cross-pollination, you can:
- Plant different varieties of the same species at least 100 feet apart.
- Use physical barriers, such as row covers or trellises, to separate different varieties.
- Hand-pollinate your plants to control which pollen fertilizes the ovules.
- Remove any volunteer plants that may have sprouted from previous crops.
