Pollination<\/h1>\n

\"GardenStep outside on a sunny morning and if you\u2019re lucky, you\u2019ll hear the low pleasant hum of bees going about their daily work of collecting nectar and pollen.\u00a0 As they do, they transfer grains of pollen from flower to flower, a process many plant species rely on for survival.\u00a0 In the vegetable garden, pollination is more important for some plants than for others.\u00a0 Crops grown for their leaves (lettuce, cabbage, basil) or roots (carrots, radishes, onions) don\u2019t require good pollination to produce the part of the plant we want to eat.\u00a0 But to develop fruit (peppers, melons, zucchini) or seeds (corn, dry beans, grains), plants need to be pollinated.\u00a0 While those busy bees are the most visible signs that pollination is happening, not all vegetables need bees for pollination.<\/p>\n

Wind-pollinated vegetables<\/span> \u2013 Corn, beets, chard, and spinach depend on the wind to carry their pollen from plant to plant.\u00a0 Beets, chard, and spinach are grown for their leaves and roots, so ensuring pollination isn\u2019t essential (from the standpoint of the human gardener and cook, anyway).\u00a0 Corn, however, requires a transfer of pollen from the tassels to the silks in order to form ears of plump, full, juicy kernels.\u00a0 For this reason, corn should be planted in blocks at least four rows wide rather than one or two long rows, so each plant is surrounded by the maximum number of other, pollen-releasing, plants.\u00a0 Saving seed from wind-pollinated vegetables is difficult, as the pollen can travel great distances, crossing with other varieties or even related wild species.<\/p>\n

Self-pollinated vegetables<\/span> – The flowers of self-pollinators contain both male and female parts, so that pollen transfer can easily take place within the flower without needing insects or wind to spread it around. \u00a0Beans, peas, tomatoes, eggplants, lettuce, and peppers are usually self-pollinating \u2013 saving seed that will produce a plant just like the parent plant is easy with these, because cross pollination is much less likely.\u00a0 However, it\u2019s still possible that insects will still manage to transfer a little pollen between varieties, so if you plan to save seed, it\u2019s a good idea to separate different varieties by at least ten feet.<\/p>\n

Insect pollinated vegetables<\/span> \u2013 These crops need bees and other insects to move pollen around, either from plant to plant or from a male flower to a female flower on a single plant.\u00a0 They include carrots, cucumbers, melons, squash, onions, radish, pumpkins, and broccoli, cabbage and the other brassicas.\u00a0 A healthy population of pollinating insects, like honeybees and bumblebees, is especially important to grow full-size, well-shaped squash, pumpkins, melons, and cucumbers.\u00a0 To encourage bees and other beneficial insects to visit your vegetable patch, fill nearby beds with flowering herbs (monarda, borage, thyme, lavender), annuals (marigold, cosmos, poppy, sunflower, zinnias), or perennials (clematis, echinacea, foxglove, geraniums, hollyhocks).\u00a0 Seed-saving for insect-pollinated vegetables can be tricky, because most will cross readily within species (including with wild relatives).\u00a0 A few tips:<\/p>\n

Melons<\/span> will cross with each other, so plant only one variety if you want seed that comes true<\/p>\n

Cucumbers<\/span> also cross with each other, so plant only one variety<\/p>\n

Squash<\/span> will cross within species, so plant only one variety of each species if you plan to save seed.<\/p>\n

Cucurbita moschata \u2013 butternut squash and some pumpkins<\/p>\n

Cucurbita maxima \u2013 buttercup, cushaw, hubbards, and banana squash<\/p>\n

Cucurbita pepo \u2013 acorn, crooknecks, zucchini and most summer squash, some pumpkins<\/p>\n

Peppers<\/span>, while usually self-pollinated, can be visited by bees or other insects which carry the pollen around.\u00a0 For seed saving, plan to separate varieties (fifty feet apart should be okay for home gardening purposes).\u00a0 Sweet and hot varieties, especially, should be planted apart from each other, or you may get an unexpected blast of heat from a supposedly sweet pepper next season.<\/p>\n

\"Garden<\/a>Dedicated gardeners have many tricks for manipulating pollination, like placing bags over flowers to isolate them and then hand-pollinating each one, but these general rules should get you started planning what and where to plant in order to save your own seed for next season.<\/p>\n

Sometimes gardeners report that planting similar vegetables next to each other (like cucumbers and melons, or hot peppers and sweet peppers) result in funny-tasting fruits and wonder if cross-pollination affects the current generation of vegetables.\u00a0 According to our research, this isn\u2019t the case (corn and other \u201cseeds\u201d being the exception); the results of crossing will only show up in the seed (which includes information from both the male and female parent) and not the flesh (which includes information only from the female parent) of a fruit.\u00a0 Those funny-tasting cucumelons or watercumbers are probably suffering from some sort of disease, not cross-pollination.\u00a0 \"Garden<\/span>The possible exception seems to be with hot and sweet peppers \u2013 one gardener suggests that we may taste a little hotness in a sweet pepper that has cross-pollinated with a hot pepper if you eat the whole pepper, because the heat of a pepper is in the seeds.\u00a0 We\u2019d love to hear back from anyone who has information that supports or disproves any of these ideas!<\/p>\n
