Grow Herbs for Bugs!

Even if you don’t cook with herbs there is another terrific reason for growing herbs in your garden and yard.

The flowers attract beneficial insects and butterflies. If you grow any of the plants in the Umbrilliferae family: dill, parsley, fennel- the butterflies come and lay their eggs on the plants so the hatching larva have something to eat. Those larva, the caterpillars, of course, can decimate a plant in no time. But, we get butterflies in exchange, and generally the plant recovers.

Other insects, many of them beneficial to our gardens, are attracted to herb flowers, too.

The following was posted by “Honey Gal” at Organic Consumers Association’s web forum years ago, but it’s relevant today: “I’m a beekeeper and teach classes in bee stewardship. One thing folks can do to help, even if you aren’t a beekeeper, is to make your yard bee friendly. Plant a flowering herb garden.

Bees use herbs medicinally and your plants can help make a difference. I suggest rosemary, sage, THYME (lots of it), marjoram, chives, basil, all the mints and other herbs with flowers. Bees will find them. To do more, plant native flowering bushes, too. In our area (WA) spirea and goldenrod are bee magnets. Try to have flowers in bloom through into fall.

Put out a big shallow dish of water with sticks or moss in it (so they don’t fall in) and keep it moist. If you can get seaweed, bees are particularly fond of the minerals so I keep a little pile of seaweed in the “bee pond.” All these small actions add up and make it a little easier on your local bees.”


Mint Flower- don’t be afraid to let your mints flower. The flowers bring beneficial insects to your garden. Use the flowers in teas and drinks, too!

 

 

Low growing plants such as mint and thyme act as cover for ground beetles which are good predators for lots of tiny pests. These low plants also provide shady, protected areas for laying eggs.

Tiny flowers, like plants from the Umbelliferae family: fennel, angelica, cilantro/coriander, dill, Queen Anne’s Lace, yarrow, and rue will attract tiny beneficial wasps.

 

 

Tiny flowers of Chamomile

Composite flowers (calendula and chamomile) and mints (spearmint, peppermint, lemon balm, catnip) will attract predatory wasps, hover flies, and robber flies.

 

 

Attract the above mentioned beneficial insects to combat the following:

  • Parasitoid wasps – feed on aphids, caterpillars and grubs
  • Lacewing larvae – feed on aphids
  • Ladybug larvae – feed on aphids
  • Ground beetles – feed on ground-dwelling pests.
  • Hover flies, and Robber flies – feed on many insects, including leafhoppers and caterpillars

Many common pests in gardens can be deterred by interplanting herbs among and along vegetables and in flower gardens. This practice eliminates the need for harsh pesticide use around your food crops and your family and pets.

The following list will give you some basic information regarding which herbs to plant to deter the pests that can plague your garden.

Aphids – Chives, Coriander, Nasturtium

Ants – Tansy- not useful for Fire Ants in the South

Asparagus Beetle – Pot Marigold (Calendula)

Bean Beetle – Marigold, Nasturtium, Rosemary

Cabbage Moth – Hyssop, Mint (also clothes moths), Oregano, Rosemary, Sage, Southernwood, Tansy, Thyme

Carrot Fly – Rosemary, Sage

Flea Beetle – Catmint (Contains nepetalactone, an insect repellent. Steep in water and spray on plants.), Mint

Flies – Basil, Rue

Fruit Tree Moths – Southernwood

Japanese Beetles – Garlic & Rue (When used near roses and raspberries), Tansy

Potato Bugs – Horseradish

Mosquitoes – Basil, Rosemary, Lemon Grass

Moths – Santolina

Nematodes – Marigold (Marigolds should be established for at least 1 year before their nematode deterring properties will take effect.)

Savory, Winter – Some insect repelling qualities Squash Bugs & Beetles – Nasturtium, Tansy

Ticks – Lavender (Also thought to repel mice and moths.)

Tomato Horn Worm – Borage, Pot Marigold

You can find seeds for many of the plants mentioned here at The Herb Cottage Seed Shop. Or, if you’re local, you’ll find me out and about at Markets and Garden events. Check the calendar to see where I’ll be. You can come see me at The Herb Cottage, too! Just give me a shout and let me know when you’ll be coming so I can be here to greet you! 

I hope you can use this information to better plan your next garden, whether it will be in the spring or next fall and winter, for those of you who live and garden in the South and West where mild winters allow for gardening. In mild winter areas pests are not killed off by the cold and freezing weather and can be a problem year round.

What’s Eating My Plants

Have you ever gone out to water your garden in the morning only to find holes in your plants’ leaves that weren’t there the day before?

As many of you know, I garden organically, using only safe products to combat pests and disease on my plants. I like to make my own products, but sometimes there are remedies that I cannot make that work so well. Safer brand makes some of the products I use. The following infographic and information was sent to me. I think it’s very useful and concise.

(I am not being compensated for posting this info.)


Most pest problems can be solved with four naturally-derived pest controls: neem oil, diatomaceous earth for bugs with an exoskeleton, B.T. for caterpillars, and insecticidal soap used on soft-bodied insects.

While the culprit in your garden may be pesky bugs, don’t rule out four-legged pests that can do large scale damage. If big chunks of leaves have been eaten, the vandal is most likely a deer. Keeping deer from eating your garden before you get a chance to is easily solved with a tall fence, six feet or higher, that puts some distance between them and your crops.  Damage on a smaller scale, and closer to the ground, can be caused by rabbits.

Rabbits can operate covertly, digging a crawlspace under any fencing or squeezing through gaps. Keeping them at bay may be done by knowing what their nose knows.  A rabbit’s sense of smell is what attracts them to your garden in the first place, so use it against them by planting onions on the edge of your garden, or sprinkle powdered red pepper. You can also consider making a hot cocktail to spray on your plants out of hot peppers, onions, and garlic.

Being proactive against a deer or rabbit invasion in your garden, however, may be the best method for keeping them out.  Plant deer-resistant plants along the inside and outside edges of your garden fences, or choose flowering perennials and annuals that will make your garden look beautiful and smell wonderful while still keeping rabbits away.

Some leaf-eating insects can cause so much damage in just a few days that your plants might be dead within the week!

Use this quick guide to identify the pest eating your plant and what solution would be best to keep that bug away from destroying your garden.

There are also a few additional insects, below the infographic, to keep an eye out for that could hurt your plant’s leaves.

12 Bugs That Eat Leaves

Since you rarely see the pest that is eating your plants, you often have to decide upon a treatment by observing the damage done. Here are the most common culprits who are eating your leaves and what you can do about it.

1. Leafminers are larvae of flies, sawflies, and beetles that feed on leaves and causes discolored blotches or wiggly lines. Leafminers particular like columbine, mums, citrus trees and tomatoes. The damage is usually relatively harmless to the plant but if it does get out of control spray neem oil on the top and bottom of leaves to protect them.

2. Box suckers are wingless nymphs of the box psyllids often found inside ball shaped shoot tips in spring. To control the damage, cut off the shoot tips you find suckers and discard. The damage caused by box suckers looks like tiny holes poked into leaves. Aphids, squash bugs and spider mites are all sucking insects that cause this type of damage. Red spider mite damage will show yellow mottling on leaves. Gall mites will often cause raised pimples or clumps of matted hairs on leaves. Sucking insects are mostly harmless but you can keep them away by using insecticidal soap.

3. Scale insects cause tiny blister or shell-like bumps on leaf backs, sticky excretions, and sooty mold on plant leaves. The damage caused by scale insects could stunt growth so be sure to wash leaves off and spray with horticultural oil or neem oil.

4. Thrips are tiny black flies that suck sap from leaves, which causes white patches to appear on leaves and petals of mostly indoor plants. Get rid of thrips with diatomaceous earth (DE) or insecticidal soap.

5. Vine weevil larvae are cream-colored grubs with brown heads that feed on plant roots which causes plants to suddenly collapse. Adult vine weevils are flightless nocturnal black beetles that can make notches in leaves. To kill the larvae, use nematodes and, to kill adult vine weevils, use diatomaceous earth.

6. Caterpillars are probably what comes to mind for most people when you first see holes in your plant’s leaves. For the majority of caterpillars, you can take the time to rub off the eggs you find on the plant and pick off caterpillars. It’s best to go inspect your plants early in the morning, which is when you will most likely find them chewing away. You can also apply sticky traps to capture adult moths before they can lay their eggs on your trees and plants. There are several different kinds of caterpillars that might be causing the damage. Cabbage white caterpillars love to eat brassicas and nasturtiums. Tomato hornworms are the caterpillars who often damage fruits. To get rid of caterpillars, dust your plants with B.T. Caterpillars will leave black excrement dots called “frass” on leaves. Since earwigs can cause similar looking bite patterns in leaves as caterpillars, finding frass is a good way to tell if it is caterpillars that are damaging your plants.

7. Earwigs are usually more beneficial than harmful since they eat insect eggs and adult aphids. However, they do like their fair share of soft fruits and new plant growth. Sometimes, older leaves tend to be chewed around the edges and look ragged when earwigs are involved. Use a pot filled with hay to attract earwigs and then release elsewhere. If you’re determined to kill the earwigs invading your home, sprinkle diatomaceous earth around and on plants with bite marks.

8. Sawfly larvae are caterpillar-like white larvae that eat leaves on plants like roses, gooseberries and Solomon’s seal. Leaf rolling is a sign of sawflies. They lay their eggs on plants and their larvae eat the leaves, they make holes that still have some plant tissue intact so the damage looks transparent. It may eventually break down and leave holes. Use insecticidal soap or horticultural oil to protect your plants from sawfly larvae. You can also pick caterpillars off plants or spray with pyrethrum.

9.Viburnum beetles, both the adult and larvae, eat leaves, which can slow your plant’s growth and looks ugly. To get rid of viburnum beetles and larvae, throw out twigs in late summer that have viburnum beetles’ eggs on them or release lady bugs in the spring to capture the larvae.

10. Japanese beetles feed on flowers and the tissue between leaf veins. Their larvae often causes brown patches in grass. To get rid of Japanese beetles, spray your plants and grass area with neem oil and set up these Japanese beetle traps to capture the adults.

11. Slugs and snails like areas that are moist and shady and eat irregular-shaped holes in the leaf (but not along the edges). To see of snails and slugs are your plant-eating culprits, come out at night with a flashlight and look under leaves. Pour beer in a used, open tuna tin or plate to attract slugs and snails away from plants and into the beer. Slugs and snails often leave shiny trail on leaves and the holes are larger than a pencil eraser but smaller than a quarter. Slugs will also eat ripening fruit touching the ground. If you have a bad infestation, use Dr. T’s Slug and Snail Killer for quick results that won’t harm other beneficial insects.

12. Cucumber beetles can destroy an ornamental overnight. Cucumber beetles will leave tiny transparent circles on plant leaves. Take immediate action to control these plant bugs with diatomaceous earth or use row covers to protect plants before cucumber beetles become a problem.

Don’t think your plants are being eaten by any of these bugs? Animals can often eat your plants too so watch out for possums, rats, deer and rabbits around your garden.

DIY Pest Control

There is lots of information in books, magazines and on the web for homemade pest and disease control for garden problems. If you read about these, you’ll soon recognize many of the same ingredients throughout. 

And, that’s good, because it means these practices have been tried many times in different situations and they work. 

Below is a link to yet another DIY garden pest control that I found very helpful and easy to follow:

The situation is dire: a multitude of destructive super-villains are attacking your precious garden. These creatures have no remorse and they won’t stop until they exterminate every last blade of grass in your precious, green utopia.

These criminals are each specialized in a specific method of destruction and are so powerful that your innocent plants don’t stand a chance against them, alone. They can level a healthy looking garden in as quickly as a week and can leave nothing standing.

Beetles, aphids, caterpillars and a whole host of baddies descend into your garden and they are not taking any prisoners today. They are set on plundering and looting everything they see till there is nothing more left to destroy.

Is there no way to defeat them? Must you stand by helplessly and watch as they wreak havoc?

Not really. Enter the Guardians Of The Garden.
