Brilliant Purple Long Bean, Vigna unguiculata sesquipedalis

Splendid Long Beans grown by Green Team Farm in Salt Lake City, Utah.

That title is just a bunch of names for a lot of fun! Vigna unguiculata subsp. sesquipedalis, is a subspecies of the cowpea, grown around the world. It is a pleasure to grow, every inch of the way!

Long beans have a distinct flavor all their own you may need to get used to. Since they are a heat loving bean, I wait to plant mine in June after my other beans are producing. The long beans come in later when the other beans are finishing and long beans don’t mind the last of summer heat. Just when I’m getting tired of the regular beans, there come my Long beans, tweaking my palate!

If you have a good hot summer, they grow that impossible 16 to 20″ fast and prolifically, great production per square foot! Grow them in full sun and overnight, you will get oodles of Noodles! Depending on your soil and how many you plant, you can harvest handfuls almost daily! You will be giving them away to people with an adventurous palate to delighted oohs and ahhs! Don’t neglect daily harvest when they are at peak season, or your plant will think it is done and stop producing.

Luscious Varieties!

Long beans are grown everywhere and there are a lot of kinds of them! They are grown extensively in Asia and India. Per ‘KnowYourVegetables’ Long beans are a traditional food plant in Africa, this little-known vegetable has potential to improve nutrition, boost food security, foster rural development and support sustainable land-care.

They come in pink and yellow. Green, red, purple, or all these three colors in one bean in the variety Mosaic! Mosaic seed can be purchased from Kitazawa Seed Company of Oakland CA.

The Spruce recommends these varieties for various reasons!

  • Liana: A day-neutral variety that starts producing early in the season. It is also recommended as a fall crop in warm climates. (70 days)
  • Purple podded: Good for hot seasons. Retains most of its color when stir-fried. (90 days)
  • Red noodle: Similar to purple podded, but more flavorful with a crunchier texture. (95 days)
  • Stickless wonder: An unusual dwarf variety [that means it can be a container variety!]. The vines only grow to about 30 inches tall and do not need trellising. Plants start flowering early (40 days) but, like many bush beans, they don’t have as long a season as taller vining varieties. (54 days)
  • Yard long (white seeded, black seeded, red seeded, extra long): Often you will only find seed packets labeled as Yard Long Beans, but there are subtle differences between varieties. Any of the green varieties would be a good place to start experimenting. (90 days)

If your planting area is a 6 hours of sun area or your weather is unseasonably cool, it will take longer for production to start and your season will likely be shorter, so plant earlier if possible. Do your research for early varieties and ones that don’t get or are mildew resistant.

PLANTING AND CARE

Companions Beans don’t mind sharing but not with onion family plants. Instead, put cucumbers at their feet, and trellis the cukes too. Keeps them clean and free of ground insects. Add some radishes to discourage Cucumber beetles – those cute little green with black dots insects. Remove them instantly. Squish, stomp, whatever it takes. Bad news, they carry bacterial diseases and viruses from plant to plant, such as bacterial wilt and mosaic virus. White potatoes repel Mexican Bean Beetles. Put potatoes on both sides of your trellis.

Soil The variety of soil needed is not strict, but well-drained soil is good. Organic matter is good, but not too much Nitrogen since as a legume, they make their own! Too much and you get leaf, no to few beans. Plant seeds about 1 inch deep about 6 inches apart. In warm zones, you can plant 2 to 3 times, at 2-week intervals, and is definitely a late summer or fall crop. Keep them moist. Fertilize as needed.

Believe me, a vertical support, trellis, wire, fence, are good for a clean harvest, otherwise your beans are on the ground, and they aren’t always easy to see among the foliage and you are stepping on them! Put your trellis up when you plant! The babies can grow quickly making it difficult to install your support system later.

Once your seedlings are up with 2 to 4 leaves, give them the royal treatment ASAP! One regular Aspirin, 1/2 teaspoon liquid dish soap (surfactant), per gallon of water. While you are at it, add a 1/4 C nonfat powdered milk and Tablespoon of Baking Soda as well. Aspirin, triggers a defense response and stimulates growth! Nonfat powdered milk is a natural germicide and boosts the immune system. Baking Soda makes the leaves alkaline and inhibits fungal spores – that’s MILDEW, the nemesis of beans that aren’t resistant! Use especially on your young bean plants, all your cucurbits – cukes, zukes, any mildew prone plant like zucchini. Use a watering can that has a rose (nozzle) that turns upward to get the undersides of leaves as well as their tops. Prevention is better than a remedy, believe me. So feel free to treat your babies after rains, once a week or as often as you can if you just can’t do once a week.

Beans are legumes, and legumes grab N, Nitrogen, right out of the air and deposit in little nodules on their roots! But. They are enthusiastic heavy producers, so a little light feeding of liquid fish/kelp mix is good at flowering time, maybe every couple of weeks. A Tablespoon in a full watering can, and later in the season too if you see the leaves yellowing. They are hungry. If you get lots of leaf and no flowers, lay off the N; rebalance your soil by adding some P, Phosphorous. P is for rapid growth, strong roots, more flower, fruit, and seed production.

Long Beans bloom in lovely pairs. Vigna unguiculata sesquipedalis

Once you get blooms, tiny beans will soon be forming. Sometimes they aren’t quite strong enough, for example when the weather is cooler, and aren’t able to push the bloom off. Give the flower a little tug and the bean will be free!

Keep your beans harvested or your plant will think it has done its job and stop producing. Harvest while they are more young for tender, crunchy juicy beans – snap! Be a little careful when harvesting so you don’t damage your plantie and open it to diseases.

Pests & Diseases

Bless aphids. Hose them off or use a spray mix that kills them and the ants but not your plant! Just test that mix on a leaf or two to know if your plant can tolerate it. I use a 1/2 and 1/2 water/alcohol mix with a dash to a 1/2 t liquid dish soap, preferably Dawn. I kill the aphids and the ants that support them. Spray sparingly.

The Mexican Bean Beetle is a species of lady beetle, looks like one too. It is a notorious agricultural pest, one of the few lady beetles that feed on plants rather than other insects. They are yellowish-brown, 1/4-inch beetles with 16 black spots on their wing covers. They bother green beans more than Long beans. Growing your rows of beans between rows of potatoes helps. See all about them at Mother Earth News!

The other bean pest is white flies. Ugh. Spray those little buggers away with your hose and invite them to not come back! Check daily until they are GONE. See IPM

Mildew is a common disease, but there are varieties that have NO mildew at all. This was proven to me when two kinds of green long beans were grown at our community garden at the same time, 16′ away from each other. We had a Chinese gardener and a Vietnamese gardener. At the time I had no particular interest in long beans, and didn’t know the significance of the difference. Oh, how I wish I had. I would have gotten the names of the varieties. One of them had no mildew whatsoever! I highly recommend you search for the mildewless varieties! See the prevention mix above!

Delicious Red Noodle Long Beans! Vigna unguiculata sesquipedalisHarvests! There are two kinds!

First are those tasty fresh handfuls you carry to the kitchen!

Second is at the end of the season when you save seeds from your healthiest monster producing plants! They are the most localized to your garden space and you. It’s as simple as waiting for the pods to dry on the vine, collecting the seeds, and completely drying them again, well before storing in jars in a cool place. Check on those jars a week or two later to be sure no insects have hatched.

Plentiful GOOD FOOD!

Nutritious! Beans are high in fiber, have diverse antioxidant carotenoids, give a quarter of your day’s requirements of vitamin K, a fat-soluble vitamin that’s important for healthy bones and blood clotting, and are a good source of absorbable silicon.

Long Beans are luscious and can be prepared variably to your happiness! They taste good right off the vine, young and slender or chop dropped in a cool summer salad with a special dressing! They are yummy lightly steamed, buttered or drizzled with olive oil, or a sauce of your choosing. Chop in very short sections, add to omelettes. Chop in 2″ diagonal sections for soups, stews! Pickle or go probiotic! Go Southern-style with ham or bacon and butter, roasted, chilled in salads, stir fried or sautéed with sauces and garlic! Hungry?! Mix ’em in your mashed potatoes or with fermented bean curd! Add them to breakfast omelets or a special quiche!

Super tasty International Options! You can use your long beans interchangeably with green beans, but they give dishes that different mysterious flavor that Long Beans have! Snake River Seed Cooperative says ‘Delicious, uniquely flavored beans add authenticity to Asian stir fries and curries. A staple in Thai curries, they’re also delicious lightly steamed on their own.’ Try in the popular Szechuan dish ‘Dryfried Beans.’ In Malaysia, they are stir fried with chillies and shrimp paste (sambal) or put in cooked salads (kerabu). In the Philippines yardlong beans are usually boiled, cooked in coconut milk with cubes of squash, or cooked adobo style with soy sauce and optionally a meat like pork. Try all these recipes! Freeze some for quick tasty winter meals!  

May your Long Beans be Many and Long!

The Green Bean Connection newsletter started as correspondence for the Santa Barbara CA USA, Pilgrim Terrace Community Garden. All three of Santa Barbara city community gardens are very coastal. During late spring/summer we are in a fog belt/marine layer area most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is.

What’s happening with my tomatoes?! 

Early BlightFusarium Wilt, Verticillium WiltLate Blight

Tomato – Healthy SunGold!

Tomato – Verticillium Wilt, Yellow Flag effect

This?!                                                 Or this?

This is bar none, the most common summer question I get asked! Potatoes, tomatoes, and the various forms of lettuce are the top three favorite vegetables in the US, so you can see why this is THE question! Since fungi spread as simply as by the wind, I will be campaigning for more tomato plant care, starting with what people can do now to keep the fungi from overwintering, then in the spring to lessen its chances. There are more things that can be done than I knew! Read on!

About Fungi  To emphasize the potency of these fungi: Late Blight of potatoes and tomatoes, the disease that was responsible for the Irish potato famine in the mid-nineteenth century, is caused by the fungus-like oomycete pathogen Phytophthora infestans. It can infect and destroy the leaves, stems, fruits, and tubers of potato and tomato plants. Before the disease appeared in Ireland it caused a devastating epidemic in the early 1840s in the northeastern United States. Not only do the fungi feed on your tomato plants, but take a look at your potatoes, peppers, eggplant, cucumbers and beans! See those yellowing leaves? Remove and dispose of them ASAP! That removes zillions of spores so they can’t spread. The wilts and blights also affect trees! Sadly, not only do your plants look depressing, production is zilch, they die an unnatural death. Remove, replace. Be happy.

How do fungi work?  Spores are spread by rain/watering splash, insects, and wind, and through our hands and tools (wash your hands and tools after handling infected plants) and through these mediums, can travel distances. That’s why it is so important, in our community garden, to tend our plants, so our neighbors’ plants won’t also be infected.  Educate your plot neighbors, better yet, send this to them! Spore spread is most rapid during conditions of high moisture, marine layer days, and moderate temperatures (60°-80°F). Once established, the fungi can over winter in your garden on debris and weeds.

What they look like on your plant: 

Tomato – Early Blight

15 Fungi Preventions!

Cultural control practices alone won’t prevent disease during seasons with wet, cool weather. However, the following measures will improve your chances of raising a successful crop.

Things you can still do this season!** Things you can do now to prepare for next season!**
  1. Buy toms that are tagged VFN, or just VF – that’s Verticillium Wilt and Fusarium resistant or tolerant. Varieties that set fruit early, at lower temps, are Early Girl Improved, Fourth of July, Enchantment. Excellent resistant varieties are Champion, Husky Red, Better Boy, Ace Hybrid, Celebrity.  
  2. Plant only healthy-appearing tomato transplants. Check to make sure plants are free of dark lesions on leaves or stems. If starting transplants from seed, air-dry freshly harvested seed at least 3 days.
  3. Plant cukes and toms on a special raised mound/basin with the bottom of the basin above the regular soil level. See more on this page in the section, Special Planting and Growing Tips!
  4. Remove volunteer tomatoes and potatoes.  If they are a not a resistant or tolerant variety, when they get sick, they increase the chances of your resistant varieties having to fight harder to live, and your good plants may not win the battle.  Do not let volunteers grow, even on compost piles, cute as they are. Infected tomato refuse should be put in the trash, NOT in green waste or your compost.  
  5. **Create a soil barrier, mulch! Newspaper/cardboard covered with mulch or grass clippings doesn’t let the soil dry out. Moist soil is fungi habitat – we want that soil to dry. Use no more than one inch of straw. It is easy to lay on and allows light to get through and air to flow and dry the soil, stops the splash factor. Above all, you don’t want wet soil to contact your plant’s leaves. When that straw gets tired and flattens, trash it and replace with new clean light fluffy straw.   
  6. **Avoid wetting foliage when watering, especially in late afternoon and evening. Water at ground level! Watering the leaves creates a humid micro climate; the fungus produces spores. Dry leaves. Dry leaves. Dry leaves. No moisture, no spores.  
  7. **Air circulation, plant staking and no touching. Air circulation allows the wind to blow through your plants. This allows the timely drying of leaves and it helps break up micro climates. If your plants are packed too tightly together, they themselves become barriers to drying. Staking your plants to poles and using cages helps them grow upright and it creates gaps between the tomato plants. You want wind and sun to reach through and around your plants. And getting more sun, your toms will ripen sooner! Moisture is needed for fungi to spread. Dry is good. Tomatoes should be planted with enough distance that only minor pruning is needed to keep them from touching each other. In the case of tomatoes, scattered interplanting, biodiversity, is always a better choice than row planting where disease easily spreads from plant to plant.  
  8. **Spray proactively. Wettable sulfur works. It is acceptable as an organic pesticide/fungicide, is a broad spectrum poison, follow the precautions. It creates an environment on the leaves the spores don’t like. The key to spraying with wettable sulfur is to do it weekly BEFORE signs of the disease shows. Other products also help stop the spread. Whatever you select, the key is to spray early and regularly.  
  9. **When your toms are about a foot tall, water neighboring plants, but not your toms. Plant water loving companion plants, like Basil or the Plant Dr Chamomile, next to your toms; water them all you want! Make a basin around your toms to keep water OUT! That keeps the soil drier near your plant, so the fungi can’t thrive there. Your tomatoes will get plenty of water by their deep roots.  
  10. **Remove bottom leaves, again, no touching (the ground), and prune your plants. Barbara Pleasant at Mother Earth News says, ‘When the lowest leaves are removed just as the first leaf spots appear, you also remove millions (zillions) of spores. And, because the bases of pruned plants dry quickly, the spread of the disease is slowed because early blight fungi need damp leaves in order to germinate and grow.’ Create an 18 to 24 inch barrier gap or safe space between your garden soil or mulch and the first leaves of the tomato plant. If the spores can’t splash upwards and reach the leaves, they can’t take hold. The stem usually isn’t a place for the spores, though it can be. Best is to remove the bottom leaves before the spores start!
    .
    If you have large plants, you might consider thinning some branches to let the sun and wind blow through the main body of your tomato plant. But, some gardeners don’t recommend pruning or snipping the suckers, the mini branches formed between the trunk and branches, because spores can enter through these cuts. If you decide to prune, the less cuts the better. Prune on hot, dry, unwindy days, mid morning to midday, after dew has dried, so cuts can dry and heal with less chance of airborne fungi getting into them. Try not to touch the cuts after they have been made. Use clippers for a clean cut. Wash your hands, in a rinse of water & alcohol, frequently so you don’t further infect healthy parts of your plant.  
  11. **Remove infected leaves immediately. A leaf should be completely green. Look for brown spots or yellow spots or distress. Remove leaves and prune when it is dry and sunny, not windy. Wash your tools and hands often.  
  12. After the tomatoes set, add some nitrogen. A healthy plant tends to fight off the spores. You don’t want to add too much nitrogen to your tomatoes before they set fruit. Too much nitrogen before fruiting leads to more leaves and less fruit. Add N only once.  
  13. **Rotate your crop if possible. Because fungi also affect other plants, rotation in small gardens isn’t practical or even possible. But if you have the room, move your tomatoes to areas that are fungi free.  
  14. ****At the end of the season remove & trash, don’t compost or put in green waste, all infected debris and surrounding debris. Pull all the weeds because spores can over winter on weed hosts. You want to reduce the number of spores laying in wait.  
  15. **The spores aren’t super spores. During our winter season, turn your soil about 10 inches, burying the spores helps remove them, and it also exposes snail eggs to die.

Preventive Foliar Mix that does wonders! 

Apply every 2 to 3 weeks, so new growth will be covered.  Wet under and over the leaves.  Per gallon add:

  • One crushed regular strength aspirin
  • 1/4 Cup nonfat powdered milk
  • Heaping tablespoon baking soda
  • 1/2 Teaspoon mild liquid dish soap

Water your plants with an aspirin?!  Salicylic acid, in aspirin, triggers a defense response in tomatoes and other plants as well! Adapted from eHow:  The main benefit of aspirin in planting involves aspirin’s ability to fend off potential plant diseases.

  1. Purchase regular strength aspirin. The brand does not matter; purchase the cheapest brand that is available.
  2. Mix together one aspirin with one gallon of water. Combine the ingredients well, so that the aspirin is distributed evenly throughout the liquid.
  3. Add a half teaspoon of mild liquid soap to the mixture. This is used as a way to help the aspirin water stick better to the tomato plants. Once the soap is added, attach a spray nozzle to the gallon jug and it is ready to use.
  4. Spray the tomatoes when you first set them in the ground. Aspirin sprayed directly on seeds improves germination, on plants it stimulates the growing process. There is no need to soak the area. A light and gentle spray will suffice.
  5. Continue to spray the aspirin mixture on the tomato plants every 2 to 3 weeks. You are going to notice that the plants stay healthier and attract fewer insects.

Per a comment by Leroy Cheuvront at Heavy Petal blog:  I have had the blight and have stopped it from destroying my tomato plants. All you have to do is mix 1/4 cup of bleach to a gallon of water and drown the plant from top to bottom, it will not kill the plant. I do it every seven days and the blight has not returned.  — June 18, 2010. It sounds scary, but I bet it works! I would test this principle on ONE plant to be sure it is safe to use.

The summer of 2019 I finally got up the courage to try Leroy’s Bleach mix! IT WORKED! I started after my plants were showing wilts signs, figured I had nothing to lose ~ totally scared it would kill my tom I tried it on first. Just like Leroy says, it will not kill the plant! Whew! I wasn’t religious with the weekly treatment but my plants vastly improved and lasted months longer than usual.

Solarization  In the past ten years, some enterprising Israelis came up with solarizing. Moist soil is covered with transparent plastic film for four to six/eight weeks in the summer. It takes that long to heat the soil to a temperature and depth that will kill harmful fungi, bacteria, nematodes, weeds, and certain insects in the soil. Some gardeners won’t use solarizing because it kills beneficial soil organisms too… Solarization can be a useful soil disinfestation method in regions with full sun and high temperatures, but it is not effective where lower temperatures, clouds, or fog limit soil heating. Solarization stimulates the release of nutrients from organic matter present in the soil.

Solarization

Solarization also kills grass by heating up the soil when daily temperatures exceed 80°F. Weed eat or mow the area as short as possible. Moisten the soil and cover the area in clear plastic for 10-14 days, until the grass is dead. Although cloudy weather will slow things down by cooling the soil under the film, a few weeks of sunshine will improve your soil dramatically, easily, and inexpensively. If you live in an area with cool or cloudy summers, or if you just don’t want to wait all season, you can speed up the process by adding a second sheet of plastic. Using the hoops commonly used to elevate row covers or bird netting, raise the second sheet of plastic over the ground-level sheet. The airspace between acts as a temperature buffer zone during cloudy weather and the combination of the two sheets of plastic serves to raise the soil temperature an additional 6 degrees. The goal is to raise and maintain temperatures in the top 6 inches of soil to a level between 110 to 125 degrees F. After several days of sunshine, soil temperatures rise to as high as 140 degrees at the surface and well over 100 degrees as far down as 18 inches. Do not mix untreated soil into the solarized bed!

And please, do NOT compost diseased tomatoes, infected trimmings or removed leaves, or any other diseased plant. That’s how you spread soil borne fungi, let alone that they are also spread by wind, are airborne. Put them in the trash, not green waste. If your neighbor has a diseased plant, don’t be shy to respectfully and gently ask them to remove it. Remember, they raised that child. How hard was it for you to give up your plant? Especially the first time. See? They may not even know about wilts. Educate them if possible. Tell them how you learned about it. Offer to send them the link to this page.

Biofumigation  Biofumigation is a sustainable strategy to manage soil-borne pathogens, nematodes, insects, and weeds. Initially it was defined as the pest suppressive action of decomposing Brassica tissues, but it was later expanded to include animal and plant residues. 

Other Tomato Questions & Cures – Holes, spots, brown areas?  Here is an IPM (Integrated Pest Management) image page from UC Davis that is likely to answer your question! It includes diseases and pests. Do take a good look at it!
