A Beginners Guide to Pollination

Gardeners often talk about the importance of bees and butterflies. While these pollinators are important, there are other aspects of pollination that are sometimes overlooked. Learning about the process of pollination can help gardeners produce more food and save seed successfully.

How Does Pollination Work?

Pollination occurs when the pollen, a powder containing male reproductive cells, is transferred from one flower’s anthers to another flower’s stigma. As plants can’t make this transfer themselves, they rely on outside forces to move the pollen. Pollination can occur in several ways.

Is Pollination Necessary?

Pollination is necessary for all plants to produce seed. Certain vegetables also require pollination to produce a yield. These include fruiting crops such as tomatoes, squash, beans, and corn. Root and leaf crops like beets and lettuce don’t require pollination to produce a yield but still need to be pollinated to produce seed.

Insect & Animal Pollination

When we think of pollinators, we typically think about bees and butterflies. In reality, various insects and animals pollinate plants, including moths, flies, wasps, birds, and even bats!

Pollination isn’t intentional on the part of the animals or insects. These creatures accidentally transfer pollen from one flower to another while harvesting pollen, nectar, or both.

Bees are considered some of the best pollinators of food crops. Their bodies are covered with bristly hairs which collect pollen electrostatically. The pollen rubs off on other flowers as they continue to collect it. Some native bees, like the Southeastern Blueberry Bee, also specialize in specific plants and do a better job at pollination than other species.

Wind & Water

Wind pollinated crops produce billions of super light pollen grains that are easily carried by the wind. They typically have feathery stigmas to help catch wind-borne pollen. These crops include most grains like corn, barley, wheat, and oats. Many nut trees are also wind-pollinated. 

In our Corn Growing Guide, you may have noticed that it says to plant corn in blocks at least five rows wide for good pollination and well-filled ears. As corn by wind-pollinated, it has a much better chance of being pollinated in larger block plantings than if you plant a row or two.

You may occasionally notice insect pollinators visiting these crops. Bees and other insects may gather pollen but are generally ineffective at pollination.

Water pollination is rare but there are a few species of aquatic plants that rely on pollen transfer through water. 

Human

Why would humans need to pollinate crops? Hand-pollination is typically done when natural pollination is either lacking or undesirable. 

The most well-known example of hand pollination being necessary is vanilla. The vanilla orchid, which is native to Mexico, is pollinated by a specific species of wild bees. Vanilla crops grown in other locations such as Madagascar have to be hand-pollinated because natural pollinators don’t exist.

Natural pollination may be undesirable when breeding plants or avoiding cross-pollination. When trying to breed a new variety or create a specific hybrid, gardeners may rely on hand pollination. You can also use hand-pollination to keep plants from cross-pollinating if you don’t have the space to separate them the necessary distance. Bagging or covering and hand-pollinating flowers will keep your varieties pure.

Hand pollination is simple to do. You need to identify the flower’s anthers and use a cotton swab or small brush like a paintbrush to move pollen to another flower’s anthers.

Keeping these pollination facts in mind can help ensure your garden is a success.

5 Butterflies Found in the Mid-Atlantic & What to Plant for Them

By now many have heard about and understand the plight of the Monarch butterfly. Over the last few decades, their numbers have been steadily declining as they face food and habitat loss as well as pesticide exposure. Though they’re certainly a deserving and beloved species (plant milkweed!), Monarchs aren’t the only insect or even butterfly that’s struggling. Here are five slightly lesser known butterflies found in the Mid-Atlantic and what you can plant this year to help them.

American Copper Lycaena phlaeas americana

The American Copper’s is a fairly common butterfly though anecdotally it is seen less frequently today than in the past. These butterflies are orange and grey with black spots.

American Copper caterpillars preferred larval host plant (the plant where a butterfly lays eggs and is eaten by caterpillars) is Sheep Sorrel though it will use curly dock. Leaving sheep sorrel and curly dock available is important for their survival. As adults American Copper butterflies will feed on a wide variety of available flowers.

Black Swallowtail Papilio polyxenes

Commonly mistaken for other swallowtails this mostly black butterfly can be distinguished from other species by the black center on the orange spot on the inside corner of their hindwing. 

If you love the black swallowtail you may have to be willing to share a few of your crops. Black Swallowtail caterpillars will feed on carrots, dill, fennel, and parsley. As adults black swallowtails will feed on a variety of flowers. Like many other butterflies, they are particularly attracted to species such as milkweed, thistle, and clovers.

Common Sootywing Pholisora catullus

This butterfly can be identified by its glossy black (sometimes dark brown) appearance and the double rows of white dots prominent on the outer margins of the upper forewings. 

The Sootywing’s favorite host plants are lambsquarters, amaranth, and cockscomb (celosia). Adding some of these to your garden or in the case of lambs quarters simply letting them grow can help this butterfly thrive in your yard. Adult Common Sootywings can be found feeding on dogbane, common milkweed, purple loosestrife, and wild indigo.

Long-tailed Skipper Urbanus proteus

The Long-tailed Skipper gets its name from the long tails on its hindwings. It can also be identified by its iridescent blue-green head, thorax, and basal areas of both wings. 

This species of caterpillars feed on legumes, including cultivated varieties. Legumes include all sorts of beans and peas, alfalfa, clovers, and wisteria. Many of these species also happen to be really easy to grow. In their butterfly stage, they will feed on a variety of flowers.

Orange Sulfur Colias eurytheme

The Orange Sulfur can be identified by yellow-orange to darker orange upper wing surfaces.

Like the Long-tailed Skipper, Orange Sulfur Caterpillars feed on legumes. However, Orange Sulfurs have a strong preference for alfalfa earning them their nickname the alfalfa butterfly. As adults, they aren’t selective about which type of flowers they feed on.

Additional Tips

A few great flowers for many butterflies include:

The most important consideration with flowers is providing blooms throughout the season. Plant successions and choose flowers with a variety of bloom times from early to late. Choosing native plant varieties can also help butterflies succeed.  Check out our Welcome-to-the-Garden Pollinator Collection.

Avoid the use of pesticides whenever possible. Even certified organic pesticides can affect more than the targeted species. Especially if you live in a dry area consider adding a water feature for butterflies and other pollinators to drink from. 

These are just a small fraction of the Mid-Atlantic’s native butterflies. If you’d like to help butterflies and other pollinators consider some of these tips as your planning and working in your garden this season. 

Planning a Pollinator Garden

Thankfully it seems people are coming around to the idea that our pollinators are in trouble. Wildflower packets and seeds bombs are “in” right now. While they may provide some relief, saving our precious bees, butterflies, moths, and other insects is going to take a little more than tossing a seed bomb into an empty garden bed.

Pollinators need food sources all season long from very early in the spring to late in the fall. In many areas native wildflower and meadow species have been replaced by monoculture lawns and select ornamental flowers. While this isn’t the only reason our pollinators are dying it certainly is a contributing factor. If you truly want to help pollinators it’s important to learn to plan a garden that offers an abundance of food sources all summer.

Timing

Figuring out how to have a garden that’s always in bloom can be a bit tricky. You’ll need to plan your plantings to maximize your garden’s potential.

Start Plants Early

Butterfly Weed

For many hobby gardeners flowers get planted when all danger of frost is past. Unfortunately many pollinators are active early and need flowers as soon as it’s warm enough to move around. If you don’t start flowers ahead of time there won’t be any flowers when they need them most.

The easiest way to start flowers early is to start them indoors. The Southern Exposure Beginner’s Growing Guide is a great resource and can help you get a jump on the season.

Another great way to have early blooms is to plant perennial flower varieties like Butterfly Weed or self-seeding varieties. These are often sooner to bloom than the annuals.

Succession Planting

Some families may already practice succession planting in their home vegetable garden. Just like it’s better for families to have summer squash spread throughout the season than a ton all at once pollinators do better if you’re plants’ bloom times are staggered too.

To help pollinators with this problem it’s simple to start flowers in small batches, every two-four weeks depending on the variety so that they’re not all blooming at the same time. This can be done indoors in seedling trays or direct sowing in the garden.

For example single stem sunflowers generally only have pollen for about two weeks. To extend your harvest you can sow batches every two weeks. Just take into account your chosen variety’s “days to harvest” to ensure all of your plantings will bloom before fall frosts.

Selecting Varieties

Everyone has trouble picking out seeds. There’s so many varieties and so little time and space! For your pollinator garden there’s a few special considerations to help you narrow down your list.

Bloom Period

Typically flowers are selected for their looks and smell but for your pollinator garden you’ll want to consider when varieties flower, what time of day they flower, and how long they flower.

Some plant varieties offer much longer blooming periods than others. Often these varieties are favorites for cut flower growers but they can also be helpful for pollinators. Some great long blooming flowers include Cosmos, Zinnias, Bergamot, and Poppies.

Sadly moths are often forgotten in the pollinator conversation. Moths are beautiful and absolutely play a necessary part in the ecosystem. To give them a helping hand plant varieties like Four O’Clocks or Evening Scented Primrose which bloom in the evening.

Native Wildflowers

Another consideration when planting for pollinators is to be sure and include native species. Those free promotional wildflower seed packets are great but they may not include varieties that are essential to the survival of your local pollinators.

Native wildflowers are also well adapted to your local climate meaning that they can do well with much less watering and maintenance. They’re great for pollinators, the environment, and you! What’s not to love?

Some of my favorite native wildflowers from Southern Exposure include the Appalachian native Lemon Bergamot, the aptly named Butterfly Weed, and Texas native Red Drummond Phlox.

Dual Purpose Flowers

Echinacea

If you’re like me your garden is all about practically. While helping pollinators is obviously important to having a successful farm I still like to squeeze extra productivity where possible. I often pick varieties of flowers that are edible, medicinal, or can be used for dye. If you’re all about making the most of your garden space check out these varieties.

Edible Medicinal Dye
Bachelor’s Button Anise-Hyssop Coreopsis
Bread Seed Poppy Bergamot (Bee Balm) Hopi Dye Sunflower
Grain Amaranth Calendula
Johnny-Jump-Up Chamomile
Mexican Mint Marigold Echinacea
Nasturtium Feverfew
Red Clover Hyssop
Sunflowers Lavender

Other Ideas

Aside from a carefully planned flower garden there are several ways to incorporate more blooms into your property.

Save Seed

You may think that plants like lettuce and radishes offer little benefits to pollinators because they’re harvested before they flower. However if you choose to save seed they’ll flower before you harvest your seeds.

Cover Crop

Never leave soil bare! Not only does it contribute to nutrient depletion and erosion it’s also a waste of valuable space. If you’re letting a section of garden rest for the season consider a cover crop like alfalfa or clover which fix nitrogen in your soil and flower for long periods. When you finish with an early crop like radishes, arugula, or peas consider quick to flower, cover crops like Buckwheat.

Leave Un-mowed Areas

If you have a larger property than you use for gardens a great way to help pollinators and many other native species is simply to leave areas natural. Without constant mowing many native species will flourish.

Sometimes all the world’s problems can be a bit overwhelming but small actions can really make a big difference. Following these tips can help you create a beautiful garden that will give pollinators a helping hand. With a little extra effort you’ll be helping moths, bees, butterflies, and other pollinators and beneficial insects.
