Tips for Organic Pest Management

Especially for new gardeners, seeing your veggies getting munched by pests can really dampen your gardening enthusiasm. There are a few ways you can solve your pest problem without resorting to chemicals.

Control

Handpicking

If you have a small garden one of the best things you can do is handpick pests. Small insects like Potato beetles are easy to squash with your fingers. For larger insects like tomato hornworms you may want to carry a bucket of soapy water to drop them into.

Note leave any hornworms with white eggs on their back. These are eggs of parasitic wasps that will help control the problem.

Ducks

Ducks and other small livestock can be helpful in ridding your garden from certain pests. Ducks are great at eating slugs! Of course, they’re a serious commitment and can also harm your garden by eating and trampling plants.

Organic Pesticides

These include products like neem oil and diatomaceous earth as well as homemade options. A popular mixture is one quart of water with 4-5 drops of dish soap and a few garlic cloves. After soaking for a few hours the garlic can be strained out and the mixture sprayed onto the plant’s leaves to kill and deter pests.

With any pesticide it’s important to keep in mind you may also be harming beneficial insects.

Prevention

While it may be too late for this season prevention is always the best option.

Plant a Trap Crop

If you notice that one particular variety of brassica is particularly infested with cabbage worms you can use this to your advantage. Use these varieties to draw pests away from others. Some folks choose to burn a trap crop that becomes heavily infested. This can help prevent pests from reproducing and being a problem the following season.

Plant a Late (or Early) Crop

If you struggled with Mexican Bean Beetles at the beginning of the summer you may have better luck with a fall crop. Experimenting with when you plant and learning about pest’s life cycles can help you work around their peak times. Keeping a garden journal can be really helpful with this!

Use Row Cover

Row cover can be used for more than just frost protection. Lightweight row cover is perfect for keeping out some pests as long as it’s set up over plants early. We sometimes use row cover or tulle to protect brassicas from cabbage moths.

Practice Crop Rotation

Avoid planting the same type of crop (ie. brassicas) in the same place more than one year. Many pests over winter in the soil and will be ready to attract plants again the following year. Check out our post, Planning Crop Rotation by Plant Family.

Attract Beneficial Birds/Insects

Some birds and insects are the natural predators to common garden pests. Making your property a haven for these creatures can help prevent pests from getting out of hand.

Keep Plant’s Healthy

Weak plants are more likely to attract pests. Keep your plants healthy by weeding, watering, and building healthy soil.

Heirlooms to Plant in July

As we head into the hottest part of summer it may feel like the only garden chores left are weeding, watering, and harvesting. However, you can still be planting some summer vegetables, fall crops, and even flowers. If you’d like to squeeze a little more out of your garden this year consider planting some of these heirlooms this July.

Summer Crops

To get good production from summer crops pick quick-growing, heat-tolerant varieties. Beans, southern peas, summer squashes, cucumbers, swiss chard, and collards are all great choices for second successions or empty spaces in your garden.

In the heat, remember to provide consistent water especially while seeds are germinating. This will greatly improve your yields.

Straight Eight Cucumber 

An old standby, this variety won All-American Selections in 1935! It’s incredibly dependable, high-yielding, and ready to harvest in just 57 days!

Creel Crowder Southern Pea (Cowpea)

Ready to harvest in just 61 days this variety is a family heirloom of Cheryl and Garey Hughes, from Garey’s great-uncle R.E. Creel, a truck farmer in Warrior, Alabama in the 1930s. They’re semi-vining plants that are very productive.

Georgia Green (Georgia Southern Creole) Collards

This pre-1880 variety is resistant to both heat and frost and tolerates poor soils. It’s perfect for areas where growing cabbage is difficult.

Pencil Pod Black Wax Bush Snap Bean

This variety was developed in 1900 by crossing ‘Improved Black Wax’ and ‘Black Eyed Wax’. It’s not as productive as modern wax beans but it is extremely tolerant of high heat. Ready in 52 days, it’s great for fresh eating and canning.

Benning’s Green Tint Summer Squash

Developed around 1914, this is one of the hardiest and most beautiful varieties of Patty Pan squash. It’s ready in 52 days and is best harvested small.

Fall Crops

July and August is actually the perfect time to start a lot of fall crops. The heat can make it a bit tough though. To improve germination and yields, keep your soil moist and use tricks like shade cloth or covering seeds with cardboard until they germinate. For more tips check out our post about direct sowing in hot weather.

Little Marvel Dwarf Shelling (English) Pea

Developed in 1908, this is an Improved American Wonder. The dwarf vines produce double-born pods. It’s ready in 62 days, resistant to Fusarium wilt, and dependable.

Oxheart Carrots

A great storage variety, these carrots are ready to harvest in 90 days and can weigh up to a pound! The short, wide, “oxheart” shaped roots do well in heavier, rocky soils than other varieties. They date back to 1884!

Early Purple Vienna Kohlrabi

This pre-1860 is slightly larger and more flavorful than White Vienna. In our trials its also shown to be more resistant to cabbage worms.

Early Flat Dutch Cabbage

The best storage cabbage, this variety dates back to before 1875 and possibly before 1855. It’s heat resistant and the 6-10lb heads are great for sauerkraut.

Flowers

Growing a few autumn flowers can keep your garden looking full and fresh until the end of the year. It’s also a great way to help pollinators.

Evening Sun Sunflower

Blooming in just 53 days these are perfect for midsummer plantings for great fall color. The 3-5 inch flowers are in shades of autumn colors ranging from red, mahogany-red, burgundy, russet-bronze, vivid gold, all in bicolor blends. Plants grow 6-8 ft. tall with a number of secondary blooms.

Mona’s Orange Cosmos

Introduced 1990 by SESE, this family heirloom is from southern California. The flowers are radiant orange and mostly single-petalled. About 10% have red-bordered petals with some interior red streaks.

Peruviana Red Zinnias

This pre-1700 variety was introduced by SESE in 1992. The flowers are of uncluttered simplicity and antique elegance. Single blooms, 1½ in. diameter, are bronze-red, changing to antique-red, then fading to pastels of red.

Midsummer doesn’t mean the end of the planting season. Keep growing with these awesome heirlooms!

5 Bees Native to the Southeastern U.S. and Tips for Supporting Them

Did you know that honeybees aren’t native to the United States? They were brought from Europe by colonists in the 1600s. Don’t get me wrong, I still love honeybees. Local honey is an amazing sweetener and they do a great job pollinating a lot of our crops. However, native bees are awesome too! Some studies show they may do a better job of pollinating native American plants like tomatoes, beans, and squash. Sadly, many of them are struggling. Check out these five bees native to the southeastern U.S. and consider using practices that support them.

Augochloropsis anonyma (a species of sweat bee)

These metallic little bees can be found in North Carolina south to Florida. They are generalists when it comes to foraging and utilize and pollinate a variety of species including those in the aster, clover, and raspberry families. They nest in relatively small ground burrows.

In the southern part of their range like Florida, they are active year-round. In the northern reaches, they’re typically only active between April and September.

Bombus affinis (Rusty Patched BumbleBee)

Like honeybees, these bumblebees live in colonies with a single queen and female workers. However, unlike honeybees whose colonies number around 10,000 individuals these bumblebees typically only have 500 to 1000 individual bees in a colony.

They also differ from the honeybee in that only a solitary queen overwinters. In spring she emerges from hibernation and selects a site for an underground nest (often a small mammal burrow) where she lays her eggs. She guards the nest, forages, and tends to the larvae until some workers mature and begin helping forage for food, tend the larvae, and protect the colony.

These bees are generalist foragers and will utilize pollen from a variety of plant species. However, they are often some of the first bees to emerge in the spring and the last to hibernate in the fall meaning they need a diverse supply of blooming flowers.

The Rusty Patch Bumblebee is severely endangered. It’s estimated that its population has declined by 87% since the 1990s and it now covers just 0.1% of its historical range! In the Southeastern U.S., its range as of 2000 included Virginia, North Carolina, West Virginia, Pennsylvania, and Maryland. Its historic range extended though the Northeast and South to Georgia.

If you have property check out the U.S. Forest Service Conservation Management Guidelines for this species.

Habropoda laboriosa ( Southeastern Blueberry Bee)

This bee rockstar is the most active February through April. As their name suggests, these bees primarily forage blueberries. They’re much more effective at pollinating blueberries than honeybees and can improve yields. They’ll also visit Eastern Redbud, Azalea, Clover, and Trumpetflowers.

They excel at early spring pollination because they can vibrate their wing muscles to warm up and fly before temperatures reach 60°F. They’re solitary ground nesters though the nests are often found grouped. The female bee builds a tunnel in sandy soil and brings masses of blueberry pollen. She lays one egg on each mass which will hatch the following spring.

Osmia lignaria (Blue Orchard Mason Bee)

Subspecies of these bees are native to both the eastern and western U.S. and are very important to commercial agriculture. These bees are more efficient at pollinating native crops than honeybees and are important for fruit orchards as they’re active in the early spring.

Blue Orchard and other mason bees are solitary species that use existing cavities to nest in like those in reeds and hollow plant stems. Unlike carpenter bees, they cannot drill into wood. These species benefit from manmade insect hotels. Like the Blueberry Bee, these bees bring masses of pollen into their nest and lay a single egg on top of each mass where they remain until the following spring.

Melissodes bimaculata (Two-Spotted Long-Horn Bee)

Another ground nester, the Two-Spotted Long-Horn Bee is a solitary species that will sometimes nest close together. Their name, “long-horn” is derived from the males’ long antennae.

They’re found throughout the eastern U.S. and are broad generalists. They’ve been seen foraging from clovers, asters, impatiens, monarda, rudbeckia, mints, asparagus, and dozens of other species.

Supporting Native Bees

There are many ways to help these incredible insects even if you don’t have a lot of land.

Stop Mowing Your Lawn

Letting your lawn get tall and flower can help native bees and native herbaceous plant species to thrive. Let it grow as tall as you can if you’re dealing with restrictions.

Talk to Your HOA or city council about pesticides.

Pesticides are a major factor in the decline of native bees. While big agriculture is obviously where a lot of pesticide use occurs some folks also use pesticides in their home gardens. Talking to your HOA or city council about banning pesticides in your area can help native bees in your area and keep your neighborhood healthy.

If you live in a more rural area just bring it up in conversations with friends and neighbors. Many folks don’t know about the harmful affects certain garden products have on bees.

Buy organic or pesticide-free produce.

Even if you don’t have a lot of land to create bee habitat you can vote with your dollar. Supporting farms that prioritize bee health is just as important as what you do at home. You can also look for farms with a BFF (Bee Friendly Farming) certification.

Plant native flowers, shrubs, and trees.

Planting flowers is great but it’ll have a much bigger impact if you select species that are native to your area. Native species are what native bees have adapted to over hundreds of years of evolution.

Also, try to select flowers that have a variety of bloom times. This helps different species of bees and ensures that those who are active for a long period like the Rusty Patched Bumblebee make it through the entire season.

Build an insect hotel.

There are many of mason bee species native to the southeastern U.S. that play an important role in pollination. You can give them a helping hand by providing them with nesting habitat in the form of a DIY insect hotel.

Leave places wild.

Especially if you have a large property try to leave a portion of it wild or as wild as possible. Don’t clear undergrowth from the forest, leave standing dead wood, avoid raking up fallen leaves and branches, and don’t mow.

Also, be smart about your garden clean up. Many dry plant stalks still standing in the fall may be filled with bee eggs and other beneficial insects. Let them overwinter so they’ll hatch in the spring!
