Spring is just around the corner here in the U.S. and garden planning is in full swing. Are you are gardener who plans to grow several varieties of each type of vegetable? Are you a frugal gardener who will purchase heirloom or open pollenated seeds so that you can save the seeds and not have to purchase seeds again next year or the next. If you are new to gardening it might be worth noting that these two methods of garden management are not necessarily compatible.
When growing multiple varieties of the same plant cross pollination can occur. If two varieties of the same type of plant do cross pollinate the product of that year will not be affected. The plant will still bare the fruit of the seed that was planted. Changes that occur due to cross pollination will only become apparent when seeds from the current years crop are grown in future years. Cross pollination can effect the color, size, and/or shape of the fruit or there may be less visible changes like flavor or texture. While the product would still be edible you may be sadly disappointed with the results.
Squash and pumpkin crosses (like the one above) are usually visually apparent. Changes in corn or tomatoes might not be as noticeable.
I have included the some links that you might find useful in preventing cross pollination
and I hope that all of your gardens are bountiful. 🙂
