Red Spider Mites Worse in Hot Weather!


Ozarks Gardening
Jim Long, Copyright 2012

Have you noticed yellow-splotched leaves on your phlox and petunias? Or on the leaves of grapes, melons, potatoes, tomatoes or other garden plants? It’s likely red spider. They especially like those crops - they really, really like phlox - but they go after over 180 different species of plants.

These tiny creatures aren’t insects, they’re actually more closely related to spiders and ticks. They have eight legs, although you can’t count them unless you use a magnifying glass. An easy way to tell if you have red spiders is to hold a piece of white paper under a leaf and shake the leaf, if you can see what looks like dust, you have mites. Look on the underneath side of the leaf, if you see very tiny webbing, then spider mites are your culprit.

Spider mites feed by sucking out plant juices causing mottled, yellow foliage. Left unchecked they can suck the life out of plants rather quickly. Damage is worse during dry, hot weather when plants are already stressed and mite populations take off like rockets. The mites can be carried on the wind and can spread rapidly to other plants. What can you do?

The worst thing you can do is to use a pesticide! Pesticides kill all the bugs on the plant, including the beneficial insects which are feeding on the spider mites. With the beneficials gone, the unhatched red spider mite eggs hatch and the population explodes, making the problem worse. Some chemical pesticides actually stimulate mite reproduction - so avoid that can of spray.
Hort. Oil Spray is not the same as Dormant Oil.

These little critters thrive in dry conditions. Wash off under the leaves with a spray from a garden hose and they won’t be happy with the moisture. Mulching plants to hold moisture and reduce stress is helpful. So is regular watering the affected plants, with one or two waterings per week. If your infestation is particularly bad, use Horticultural Oil Spray or Insecticidal Soap. Both work. Some gardeners swear a by 1-to-1 solution of rubbing alcohol and water, sprayed under the leaves. The alcohol evaporates quickly and supposedly doesn’t damage plants, however I’m a fan of Insecticidal Soap which is always reliable.


(Note: I sell Horticultural Oil Spray. It's one of the best, organic controls for garden insects and indoor houseplants. $16.95 plus shipping for 1 quart, which makes gallons of spray. Contact me at jim@longcreekherbs.com).

Another option is to encourage natural predators (you can order these to increase your beneficial population). Big-eyed bugs, damsel bugs, lacewings, ladybugs and minute pirate bugs all are happy to devour spider mites.

I highly recommend the book, Good Bug, Bad Bug, by Jessica Walliser, from St. Lynn’s Press, which has photos and controls of many garden pests.

Drought Hardy Lilies

Lillies in full bloom this week in my garden.
A couple of years ago I received a box of lily bulbs from Brent and Becky's Bulbs in Virginia. I've known Brent and Becky for many years through Garden Writers Association and so I was excited to get to try out some of their bulb varieties.

I'm mostly ignorant about lilies since I focus primarily on plants for eating. As far as I know, most lilies aren't edible, and even if they are, why would you want to eat them when they produce such beautiful flowers?

Lilies up close.
I planted my bulbs, in mid-spring as I recall. I think they're in the family of "Asiatic" lilies, which are among the hardiest and easiest of lilies to grow. They'll thrive in a variety of soils and growing conditions. These you see here are about 5-6 ft. tall and have been in bloom for several weeks. Even in our 100 degree days, these tough lilies have stood tall. I give the soil around them a soaking every few days but otherwise I haven't done anything special for them.
Brent & Becky's Bulbs catalog.

While these lilies are beautiful and a real joy to have in the garden, the bigger thrill is their fragrance. Our days are hot and miserable and it's evening when I get to spend time in the garden. As I weed and move the garden hoses and sprinklers around, just as the air is getting still and cooling off, the lilies burst forth with the most enchanting fragrances! Some evenings I can smell them from 25 feet away - not a cloying, too-sweet fragrance, but a subtle, enticing smell that as relaxing as it is inspiring. Who knew lilies could be such a delicious plant to grow?



These yellow ones bloomed earlier.
The yellow ones, a bit shorter, finished blooming before the taller, two-colored ones at the top of the page started. Sorry, I don't know the names of either variety. Both have multiplied and spread nicely and require very little care. I'm going to give them some fertilizer and bone meal so they will bloom even better next year.
 
I checked Brent and Becky's Bulb catalog today and they're showcasing their next spring's bulbs, to be planted this fall. They have a selection of some fantastical new narcissus and tulips and even in this heat, it's time to think of next spring.

I hope wherever you are, you are having pleasant weather and rain, and if you have extra to share, these drought-ridden, brown hills could use some moisture.

Good News for Gardeners


Jim Long, Copyright 2012

It seems time for some good news for gardeners for a change. With everyone's tomato plants hung with sheets to block the sun to prevent sunburning on tomatoes and making gardens look like a backyard laundry, I decided to go looking for something to be glad for. (By the way, sheer curtain panels from the thrift shop are my favorite covering to keep birds away from tomatoes and preventing sun-scald on the fruits).
Sheer curtains covering tomatoes to keep from sunburning the fruit.


Here’s something to make this weeks garden chores just a little more pleasant. Every time you see a cluster of Japanese beetles eating your roses, squash blossoms or other garden plants, you can smile and know the bugs have some bad news in their futures.

Japanese beetles were accidentally introduced into the United States in 1916 near Trenton, NY. Japanese beetles have now spread into every state east of the Mississippi River. They’ve spread as far west as Denver - although the current forest fires in Colorado are certainly making the pests’ lives more miserable.

It’s been known since 1920 that Japanese beetles can be temporarily poisoned by geranium flowers - yes, those same geraniums that are probably in pots on your patio! But no one studied how or why geraniums effect the beetles until recently, when scientists at the Agricultural Research Service (ARS) in Ohio began working on the question.

Here’s what they know so far. When a Japanese beetle eats a couple of geranium flowers - any color will do - the bug is paralyzed for about 12 hours, belly up, legs twitching in the air. This leaves it exposed to predators like birds, dogs and the heel of your shoe.

Chris Ranger, an entomologist at AHS is working on a natural, botanical formula for controlling the beetles based on compounds isolated from geraniums. Once the formula is up and working, it will be patented as a spray and we’ll all have access to it. Progress is looking very good!

Other controls available already include the product, Milky Spore Bacteria, which you spread as a powder on your lawn and garden, the bacteria infects the grub stage of the beetles and kills them before they hatch. After 2 seasons of spreading this powder throughout my lawn and garden, I have fewer beetles this year.

Another control that works is the Spring Tiphia wasp, which is an effective biological control for the beetle. You can order the Tiphia larvae and release them into your garden where they go to work on the grub stage of the Japanese beetle. (The “wasps” are tiny, you’ll likely never see one and they have no interest in humans or pets, and don’t sting unless you’re a beetle).The Tiphia wasp is attracted to peonies, so planting those will help bring them naturally to your yard.


(Note: read this discussion on a gardening forum that isn't as encouraging as what I've heard recently. You'll see that the discussion was posted in '04, so opinions may have changed about Milky Spore Bacteria results. I think I have positive results, however it could also be weather conditions that have lessened my Japanese beetle population this year. Also, it's discouraging to hear the parasitic wasp larvae are so expensive, hopefully the link I gave above "order the Tiphia larvae" can be of some help).

Watering Garden Plants

Regular watering is at intervals is better for plants than daily watering.

How You Water Your Plants, Matters

We’re all watering our gardens, coaxing them to produce, worrying when the tomatoes and beans wilt in mid-afternoon. Did you know that the watering method you use, can make the difference in success or failure?

One of our friends who visited our Garden Open House this past weekend mentioned that he’d been measuring the amount of water a tomato plant in a 5 gallon bucket uses in a day’s time. He’s determined that a tomato plant with tomatoes on it, uses nearly a gallon of water a day, through growth of the plant and respiration through the leaves. That means tomatoes in the ground require regular watering, too.

But there are ways of watering that help plants - regardless of what plant we’re talking about, be it tomato, pepper or hydrangea - and there are watering methods that can do damage. For example, using one of those hose nozzles that work great for washing your car, to water plants, is a waste. Spray nozzles, aimed at the leaves of a plant, do little for the roots of the plant. I’ve seen gardeners who like to go out every evening with the hose and spray nozzle and “wash down” the plants. While it may make the gardener happy, it does little for the health of plants, and can actually do damage.

Plants (in the ground, rather than potted plants) do best when watered every 4-6 days and allowed to dry out in between. That forces the plant to send roots deeper, which helps protect the plant. When watering is done, there needs to be enough water at the base of the plant that the soil is wet for 6-8 inches deep. Heavy mulch helps hold the moisture in place, as well.

Tomatoes, peppers, roses, dogwoods, herbs such as bee-balm (Monarda sp.) can all develop any of several fungal diseases when spray-watered late in the day. Wilting diseases on tomatoes is made worse when the leaves are left wet before nightfall. Watering the foliage of roses helps insure you will have black spot on the leaves. Powdery mildew on many plants often starts with wet leaves in the evening.

How best to water? I recommend watering plants late in the day, using a water wand (Dramm Watering Wand - those colorful, long-handled watering tools with the shut-off handle, about $17- $20 at stores). Aim the water only at the base of the plant for about 2 minutes, move to the next plant for 2 minutes, then back to the first. You want the soil wet down to at least 6 inches. If in doubt, dig down and see how effective your watering is. Do this about every 4 or 6 days. If you prefer to water your garden with a lawn sprinkler, do it early in the day so the leaves have a chance to dry and don’t water every day.

Happy gardening!

What Makes a Successful Farmers Market?

A thriving, robust farmers market is an asset to any community.

Farmers markets date back to the beginnings of our nation. Often the market was informal, simply a gathering of farmers who drove their team and wagon to the town square and sold their excess produce. The historic Soulard Farmers Market in St. Louis is the oldest continually operating farmers market west of the Mississippi River, dating to 1779. East of the Mississippi, there were even older established markets in the East.


After World War 2, at the beginning of the Baby Boom, grocery stores sprang up in newly built communities and farmers markets slowly faded away. But in recent years there's been a remarkable resurgence of the farmers market model and many communities have embraced and encouraged these markets in their area. It's evident, though, as I travel around the country visiting markets, that not all farmers markets share the same benefits. I've visited farmers markets in many countries, as well, and all share most of the same elements of our best ones in the U.S. I decided to make a list of what elements appear to go into making the most successful farmers markets. My survey isn't precise, it's simply my own observations based on visiting a lot of markets in many states.

Water for vendors and visitors.

First and foremost, the most important element I found in a successful market, is how enthusiastically the city itself encourages the market. I visited several small town markets and the ones that struggled the most and had the fewest vendors, all voiced one opinion: the city where the market was located was barely tolerated by the city government. In some instances, the city had made finding space difficult, insisting the market take the worst spots in town and changing every year where vendors were allowed. Some small towns required expensive permits. However, cities that offered encouragement and welcomed the vendors, had the most thriving markets.

Here's my list of what it takes for a successful farmers market in a community:

1- Encouragement from the city in the way of space for the market. That includes simple things like giving vendors a predictable space, year after year, where shoppers can find them and that is cordoned off so that traffic doesn't present danger to shoppers. Having restrooms open and available for vendors and shoppers is important. Vendors having access to water, both drinking water and for watering their plants during the hours they are selling, is equally important. It was startling to see how many towns with struggling markets, closed their restrooms on weekends, and wouldn't allow access to water. Making vendor fees and applications simple and easy, is also important. When a city tries to price the vendors out of business in the hope the market will go away, is detrimental to all, including the city.

Market location and signs are important.

2- Help from the city with advertising the market, with city businesses taking advantage of the increased traffic flow to the market. Something as simple as letting the market organizers use the city photocopy machine for flyers, can be a big help. Groups such as Rotary, Lions, Elks and others, giving some encouragement can be vital, as well. When civic organizations were involved and told their members about the good things the market was doing for the community, it was always helpful.

Some civic groups get involved in the markets with selling their cookbooks, encouraging new members to join, such as art guilds and neighbor-to-neighbor groups like Welcome Wagon, and find that farmers markets are an excellent way to bring in new volunteers.

Wide assortments of produce entices customers, like these purple and yellow cauliflower heads.

3- Local businesses supporting the market, even in small ways. I participated in a market last year set up on a town square. There were about a dozen vendors with fresh produce 2 days a week. Within the square were 6 restaurants and not a one of the owners or chefs ever bought a single item. People who shopped there were seen by businesses as "blocking traffic" and an irritation to the store owners rather than seeing the increased traffic flow as an asset. (In one town I visited, businesses put up signs on their entry doors, "Restrooms open only for our customers" to prevent market shoppers from going inside).
A diverse population of races, age groups and education levels is a positive thing.
4- A diverse, multi-generational population. Retirement communities and tourist towns seems to struggle the most with having successful farmers markets. Farmers markets bring in younger, well-educated shoppers who see the importance of local, often organic food and want to support area growers. 

Resting places for shoppers to rest and visit are important.
Here are a few additional elements I found at recent markets that are also helpful. Drinking fountains in the area, operational and turned on. Seating areas for shoppers - this can be as simple as benches, walls, anything where shoppers can rest and visit. Space and encouragement for entertainers. The market in Fayetteville, AR (Tuesdays and Saturdays) gives space on all 4 sides of the square for budding entertainers to have an hour to play, sing, juggle, etc. Access to restrooms is important, too. Encouragement for shoppers to bring their dogs, with signs reminding people to clean up after their dogs gave opportunity for shoppers to spend some time with their pets in a social setting.

Encouragement for young musicians to try out their craft.

At one market I found the County Extension Office with a booth and table, with garden insect displays and someone on hand to answer questions about garden bug pests. I found the Humane Society with a booth, and dogs on leashes, looking for adoptive homes for their animals. Politicians, too, had booths to answer questions about their platforms and meet prospective voters.

Shoppers of all ages.
Humane Society introducing pets to prospective new owners.

Allowing beverage and food vendors is important, as well. The best markets I've seen, all had a coffee/beverage booth so shoppers could linger and visit over a cool drink. Food sampling at the bakery booth was allowed and the fruit vendors had little covered sampler displays where you could taste apples, peaches, etc. before deciding to buy the item.

Encouraging kids is just good business for any town. After all, they grow up to be your customers!
This enterprising young man had his own booth, selling his marshmallow guns.
Another important element was activities for kids. The best markets that I visited, in California, Michigan, Texas, Kansas, Oklahoma, Arkansas and Missouri, all had something that made it fun for kids to come. Games, demonstrations, crafters who showed kids how to make something, all made for a total family environment that made it fun for everyone.

Vendors make it fun for people to shop with them.
Farmers markets are here to stay. Some towns and cities struggle to have a market. Memphis, TN, for example, has a small market given its population, while Fayetteville and Bentonville, AR both have large and thriving markets. Branson, MO, with 7 million tourists a year, struggles to have more than 3 or 4 vendors and each year the market is in a new location so it's almost impossible to find (even for us locals). Springfield, MO has 3 thriving markets and is about to build a permanent location for a market. Small towns across the Ozarks attempt to have markets but the ones that succeed, all have the backing of the city, the community and local businesses. It's exciting to see these markets as they grow and become permanent parts of their communities.

Buy Local, Buy Fresh

Most states have buy fresh buy local programs to promote agriculture.


The local foods movement seemed like a fad just a few years ago. Mainstream media and the general public basically relegated local foods advocates to a few, “radical tree-hugging, barefoot hippies,” as I heard one person declare. Well, no more. What may have once been a fad is now a national cultural shift in thinking about food sources. Food recalls and food scares for items like spinach, lettuce, tomatoes and eggs in recent years, has awakened people to the need to know the safety of their food and who produced it.

Reeds Spring farmers market is an evening market with entertainment.

I became keenly aware of how big a change this movement had become when I was a delegate from the U.S. to the first Slow Foods Conference in Turin, Italy in 2005. Gardeners, growers, artisan cheese makers and lots more, came to the conference to share how they were making a living selling to local consumers. Five thousand delegates attended that year and the conference grows larger every year.

Fresh vegetables and herbs, picked the day you buy them.

The garden interns we host at Long Creek Herb Farm each year are mostly in their 20s, young people who are intensely interested in where their food comes from. They come to learn how to grow food without chemicals, they want to know how to grow food to feed themselves and their families. Many would rather go without a food item than to buy it from a big box store.


Fresh flowers are big sellers at farmers markets.

Farmers markets are the meeting place for local growers and local consumers. Most markets won’t allow imported produce - whether it’s imported from over seas or simply grown on big production farms two states away. Many farmers markets require organic certification to even sell at their market. The advantage for consumers is we know our supplier. If you buy from a chain store, you have no idea if the produce you buy comes from China or South America or what chemicals were used. You might learn a week after your purchase that the spinach you bought was recalled because of botulism. But if you bought your spinach from a vendor you know at a farmers market, you know how he grew your produce. You know he uses ethical means of growing and washing your produce because it’s in his interests to see you again the next week. The food you buy from him is the same food he feeds his own family.


There are more farmers markets across the Ozarks this year than ever before. Increasingly the big box stores are getting in on these changes. Wal-Mart and Sysco, the world’s largest retail store and the world’s largest food supplier to restaurants, have both started adding organic produce and locally-grown foods to their food lines. Consumers have demonstrated they will buy from local producers if it is available.

Every time you buy from a local producer, whether at a farmers market or through CSA (Community Supported Agriculture) you are helping keep local money in your community. You are also helping farmers continue to produce high quality, healthy food that is safe to eat. Support your local growers by shopping at area farmers markets!
