OGQ
Southern Peas
(field peas, crowder peas, cream peas, black-eyed peas) Legume. Fixes their own nitrogen. Because of this they are high in protein. Easy to grow. Dry/hot - *draught tolerant*. 70-75 days to mature. Harvest: pod to be filled. Dry peas become seeds for next crop. support own weight
Squash - winter
(pumpkin, cinderella, butternut) - take long time to grow.
Greens (brassica)
*Cool season crops* - planted in september, harvest with frost on them. Makes them LESS bitter. Cooked generally. Collard greens, kale, mustard greens, turnip greens. (regional favorites) Collard Greens: Get a bad rap because added animal fat. "pot liquor" Caldo Verde "green broth" Kale: nutritional powerhouse Mustard: more pungent than other greens LOUISIANNA Turnip: similar to Mustards in flavor. (human & livestock consumption)
Organic Potting Mix
- 2 parts shredded sphagnun peat moss - 2 parts aged pine bark - 1 part compost - to 1 cubic yard (27 feet) add pulverized dolomitic limestone 3lbs, bonemeal 10 lbs, blood meal 5lbs, wood ash 2 lbs
Tomato Nutritional Value
- Believed to benefit the Heart - Lycopene (red) - other red fruit KETCHUP - Vitamin C - Vitamin A - Variety dependent Fruit but used as a vegetable.
Seeds and Transplants
- Buy current season's seeds. - May have to order unusual varieties. - Look for disease resistant varieties. Ex: VFM tomatoes -Buy good quality plants - look for new shipments, avoid yellow or wilted plants.
Tomato varieties
- Choose for taste - Resistant varieties - Heirloom: open-pollinated (non-hybrid) not resistant to anything Beefsteak: - Largest group, some weight 1 pound -- *Beefmaster VFN (Verticillium, Fusarium, Nematodes)* *Resistant to these diseases and pest!* -- Brandywine (pink heirloom), ugly but tasty (not resistant) -- Arkansas Traveler Salsa/Sause tomatoes (Roma): hold up to heat - Roma - Cherry/Grape: good choice for beginning tomato gardeners (start with these) - San Marzano
Early Garden Planning: Spring/Summer garden
- Develop plans January-February or earlier 1. Select a site: avoid shade, poor soil, wet and low areas, walnut trees 2. List veggies species and varieties: consider season 3. Decide how much to grow - how will produce be used 4. make a planting map
Tomato Horn Worm
- Eats leaves off tomato plants - blend in with leaves Control: - beneficial insects (97%) - Bt (Bacillus thuringiensis): bacterium that kills catapillers - Pyrethrum - Physical removal
Disadvantages of a Raised Bed Garden
- Elevated raised beds tend to dry out more quickly in the hot summer months, increasing watering needs. - Frame and soil materials for establishing a raised bed are an added expense. *Increased plant density may increase some pest concerns, especially foliar diseases.* May not be well suited for vining veggies such as watermelons and sweet potatoes.
Container Garden Care
- Fertilizer: your plants are totally dependent upon you for their food. - Container grown plants are going to require more frequent fertilizing than garden-grown. - less root volume/leaching of nutrients. - Apply soluble fertilizer every week or two. - Foliar feed with seaweed or fish emulsion for a quick pick up if plants look stressed.
Not all vegetables transplant well
- Root Crops (carrots, beets) can change shape - Leafy biennial herbs (dill) - Cucurbits (cucumbers, pumpkins, squash) Do not like root systems to be disturbed. - Vegetables growing quickly when seeded in the garden. (radish, leaf lettuce, spinach) Transplanting is not worth the effort with these.
Preparing the soil for organic gardening
- break up the soil (till,plow) prior to planting. 5 important factors to consider: 1. break up the ground 2. test soil pH and quality (send to lab) 3. add needed nutrients and organic matter 4. Add needed nutrients and organic matter 5. mulch your garden (helps with weeds long-term, conserve moisture, prevents erosion) 6. compost WEEDS #1 concern for organic farmer at first. Est. plant spacing - straight line, gentle slope Small seeds: barely cover. Thinning: don't forget to think seedlings that were sown thick such as carrots.
Common reasons for lack of germination
- improper soil temperature - soil too dry - seeds planted too deep - seeds washing away - soil crusting (rain water) - damping off disease (fungus) mulching can prevent these. add organic matter, mulching
Pest Management
- indicators of how far a production system has strayed from the natural ecosystem it should imitate - insect pests are attracted to plant that is weak or inferior - well balanced system: massive pest outbreaks are rare due to presence of natural predators, parasites, and disease agents
Transplant Planting
- plant seeds at depth of 3 times their diameter - broadcast very small seeds such as broccoli or lettuce and cover with a light sifting of soil. Does not have to be deep. LIGHT: can be most limiting. (producing warm season plants in cool season) - directly related to temp and moisture. - Need a lot of light.
Spinach
- popular - high vitamin a & b2 - not an easy crop to grow. Comes up vigorously. Grow spinach mainly in COOL weather. needs 6.5pH, use like herb.
Container Garden Tips
- slightly pre-moisten substrate before putting it in the pots. Sphagnum peat works best with warm water. - if possible, drainage holes should be on the sides of containers rather than on the bottom so excess water can drain out.
Beneficial insects
1. predators - many prey 2. parasitoids - one prey
Parasitic Flies
16,000 species of flies - Tachinid Fly

855k-1M
Baby Carrots
A true baby carrot is a carrot grown to the "baby stage" long before the root reaches its mature size. "manufactured" baby carrots: Mike Yurosek: CA farmer who used industrial green bean & potato peelers - The baby-peeled carrot was born!! Baby carrot facts: - 190Million tons of carrots are processed into baby peeled carrots. - US sales $400M annually. Sales increased 33% - 80% of all retail carrot sales are baby carrots!
Producing OWN transplants
Advantages - can ensure disease-free transplants - transplants available when needed - best use of expensive seed - produces a transplant you desire - gives you a good feeling (FUN!) Factors to consider for success: - Growing media: NOT SOIL - Light, temp, moisture are essential. Need: - seed, media, containers
Commercially grown transplants
Advantages: They are easy. Inexpensive if you only need a few plants. They do not require that you commit time and money. Better (ideal?) growing conditions. Disadvantages - hard to find Certified organic transplants - you may not be able to find exactly what you want - transplants may introduce diseases, insects, and weeds into your garden. (want to be there when the truck arrives)
Planting a garden
Advantages: exercise, satisfaction, save money, fun for all ages
Container Garden
Allows you to garden in almost any location. What do you need? Plant, place, pots, potting media, Plants/seed, provide water & nutrients. * Soilless substrates contain negligible amounts of nutrients. Must have drainage. - If not already existing need several holes 1/4-1/3 in diameter on the *sides* about 1" from *bottom*.
Beans
Annual. Easy to grow. Trouble free. Pole beans vs. Bush Beans. - PB: Don't support own weight. BB do. - replant every few weeks.

Dimensions for a raised bed
Can vary. 1. Height: minimum 8"-12" is needed for proper root development. - need room for adequate drainage. 2. Width- 4 feet is ideal to allow one to reach into the bed from both sides. 3. Length: 12 feet is ideal to minimize walking.
What makes peppers pungent (spicy)?
Capsaicin: discovered in 1816 can be isolated to use for different things. Colorless, odorless. HYDROPHOBIC: Fat soluble, not water soluble. MILK takes away burn from hot peppers than water. Active ingredient in pepper spray. Unpleasant to most mammals, whereas BIRDS are unaffected; seeds are spread. - highest concentration in placental tissue (not seeds) - inside lining. Bell pepper has a recessive gene resulting in a lack of capsasin.

Grafting Tomatoes
Grafting has been used on woody plants for centuries. More recently used for herbaceous plants like tomato. Why? Combination of desired characteristics. Disease resistance/toelrance and desirable fruit quality. Use a disease-resistant rootstock on which to graft a scion that possesses desirable fruit quality. *Rootstalk: below ground portion of plant.* *Scion: top of plant to be grafted onto rootstock.* Once the graft union is healed, the grafted tomatoes can be planted in the garden. We get the flavor characteristics we desire (scion) combined with disease resistance (rootstock).
Which of the following is an important factor to consider when growing vegetable transplants
Growing media, light, temperature (all of the above)
Hardening-off Transplants causes and ways
Hardening-off causes: - A slowing of growth - Greater cuticle thickness and waxes on leaves - build up of sugars Ways to harden off transplants - only water the transplants when they start wilting. (cycle water) - Stop fertilizing - exposure to cool temps and/or higher levels of sunlight

What is the term that Thomas Jefferson used to describe tomatoes
Love Apples
The compound present in tomatoes (and some other red fruits) that has been linked to cardiovascular benefits is:
Lycopene
Corn
Maize. Grass. WARM SEASON PLANT Eating the seeds. 332 million tons in the US. 42% of worlds population gets corn for US. - grown in mid-west. Field corn - Iowa & Nebraska Sweet corn- we eat Cultural requirements: - Tip to plant corn early is not a good tip. ( can help business wise) - plant hairy vetch to get nitrogen bc its a grass -direct seed,, not transplants white corn: silver queen, sweet corn
Raised bed Garden advantages
Maximize all available space in areas with limited space. Good for areas with poor, rocky, or sloped terrain. Filled with high quality of soil mixes that have large amounts of organic matter which improves drainage and may increase yields. Drain better and warms up fast; better seed germination and transplant growth. Dense planting techniques results in higher production per sqft of garden and helps reduce weed seed germination. Can be tended soon after rains or irrigation without compacting soils. No expensive power cultivation equipment is needed.
Celery
Negative caloric content. Blood pressure benefits - anti inflammatory. - LONG season crop. - Heavy feeder. Needs constant moisture.
Sweet Potato (Ipomoea batatas)
Not closely related to irish potatoes. ROOTS vs idaho potatoes are STEMS - more starchy - can eat foliage Morning Glory family. plant april 15th (cuttings or transplants) Fall crop plant June 15th high pH 4.5-7.0 Can grow in adaptable conditions. 90-120 days to mature
Container Garden Watering
Often, early. Throughly and deeply. never let media dry out completely. too much can kill plants. Drip; 7:00am
Leeks
Onion family. - White base, green stem Edible: Stalk Cold weather plant. Transplants. Want to plant deeply to develope white stem under the ground. - sweeter when bottoms are white. Harvest in winter through spring. COLD HARDY. need frost to become sweeter. Hill them up as they grow.
Pest Management approach
Organic approach: enhance habitat for beneficial insects. increase pop of 97% good insects. holistic approach - total system approach not just remedial (not just treating systems) prior planning helps. choose resistant varieties, use crop rotation (soil born pests, botanical family), companion planting, timing of planting ( keep notes, avoid peak pressure, experiment with different plants, plant crops susceptible to nematodes), sanitation ( select healthy plants, rogue (remove) and prune, remove crop debris promptly to reduce overwintering sites for pests, soil management. Can do these things through: Mulches, composting, tillage, flaming, and trap crops. Pest problem usual indicates sub-optimal growing conditions and imbalance. Emphasis on biodiversity and optimal cultural practices. normal resort: *Spray insecticide* - remedial approach, organic grower cannot think this way.
Tomato History - culturally and historically important
Originated in South America? - China #1, India #2, US #3 Cali. & Mexico are big producers. Thomas Jefferson called tomatoes "love apples"
Parasitic wasps
Parasitoid. lay eggs in and on host insects. egg hatches and kills bugs. Braconid Wasp - parasitize tomato horn worm,
Asparagus
Perennial Edible spears (flower stalk) Little harvest until 3rd year. Prepare beds with compost. Separate Male & female asparagus (only want males, females have red berries) diecious - Larger plant. - Likes high pH 7.0
Artichokes
Perennial in warm climate Edible flower Harvest: Unopened flower heads Tall plant: 3 foot tall, 6-8 flower heads per plant Cultural requirements: - Transplants - Keep roots cool (mulch)
The two primary categories of beneficial insects are
Predators and parasitoids
Planting Map suggestions
Put vine crops on edge. (watermelon & cantaloupe) Plant 3 rows of corn for pollination. (wind) Put tall plants (corn, tomatoes) on north side to avoid shade. Plant small amount several times to extend the harvest season. 1,000 sq ft. takes about 1 hr per week of care. - plant in rows - easier to care for. - consider equipment size for row spacing. - Double crop to use space efficiently - harvest radishes, sugar snap peas, lettuce early then plant, later-season crop in same space (peppers, beans, summer squash) - Start small
Scoville Units
Rating of Capsaicin. Bell Peppers: 0 Anaheim peppers: 500-1,000 Tabasco Sauce: 2,500-5,000 Cayenne Pepper: 30,000-50,000 Habanero Chile: 100,000-350,000
Container Garden- Selecting containers
Recycled containers: scrub well. Rinse with 10% bleach before you use them. Container dictates the environment. - Temperature extremes. - Overheating can mean death. - Thick wood insulates best. - Colors: Dark absorbs heat. Light reflects heat. Choose the right size container for the plants that you want to grow. - Bigger is better... small containers dry out faster.
Chard
Salads, steamed, sauteed. - vitamins/fiber "Bright Lights" Direct seed because they germinate fast. - Thin to one seedling (aggregate seed. 4 crops can come from 1 seed). Sow a crop every two weeks. Kinda heat tolerant.
The rating scale used to determine the pungency of pepper is comprised of:
Scoville Units
physical barrier
Small scale: bagging fruit, crawling pests, row covers, mulches (commercially), trenches, trunk bands, bates, traps, and lures
Vegetables traditionally transplanted
Small seed vegetables (tomatoes, peppers, head lettuce, broccoli) Sweet potato, irish potato - transplanted because on their own, they do not produce seed or the seed lacks vigor
Container Media
Small volume is needed to support plant growth. Desirable traits: - Water and nutrient retention - high porosity to ensure good aeration and root growth. - low bulk density (fluffy and light) easy to move. - Free from weeds, diseases and human pathogens. Low soluble salts.
Peas
Snap peas, sugar snap Eat in pod, COOL Season plant Need to be trellised. Like long, narrow things to wrap around. Sugar snap peas can produce in low sunlight.

Which of the following is NOT a cultural method commonly used for pest management in organic production systems?
Soil sterilization
Radishes
Spring's tangy farewell to winter Cool weather plant! - Quick plant to grow - Direct seed (not radishes - root crop, high germination) 3-4 weeks maturity. - Rich in vitamin C
A good way to maximize your space using a raised bed is to plant according to the ____ method.
Square foot
Melons
Summer's reward for hot, humid weather. - taste will beat anything you can find in the store. Muskemelon: cantaloupe Watermelons: 6% sugar, 92% water - *red: lycopene* (also in ketchup) healthy for you. take long time to grow. *Harvest muskmelons at full slip*: Stem almost falls off fruit. Harvest watermelons, when curled up *tendril (pigtail)*, turns brown and dies. - seedless watermelon, you need a pollinator Yubari melons: 6,000-15,000 yen. Pair auctioned in 2008 for 2 million yen
The best way to tell if your garden needs to be watered is:
Testing soil moisture with your finger
Tomatoes

Tomato Cultural Requirements
Warm season plant, grow through summer. Good soil, organic matter pH 6.0-6.8 Mulch & irrigation needed Grow as transplants, almost always! Like a lot of nutrients and water. need stakes to support plant. Crop rotation: VERY IMPORTANT to break disease cycles > nightshade family: Solanaceae - potatoes, eggplant, peppers. > Rotate with non-solanaceae (cucurbits are best) crop every 3+ years Growth Habit - Determinate (bush) - Indeterminate (vining) Both cannot support itself. Staking/caging: - individual - multiple Florida weave - twin around plant- all leaning on the same post - Topsy, turvy
Tomato Cracking
Warm, rainy weather after a dry spell. (same as cabbage head splitting) there are crack resistant varieties.
Growing media
Why not use garden soil? - tends to be poorly drained and subject to water logging. - Contains insect pests, diseases, and weed seed. GOOD: - Free of pests - Good water-holding capacity - Well aerated and drained - Low in soluble salts Examples:- Vermiculite: mica-like material that has been heated to high temps, helps water drain. - Perlite: An inert lightweight volcanic material - adds air space. Coconut Coir (husks) - peat substitute also called coco peat Peat Moss: #1 for small plants. #1 component: Aged Pine Bark: used in S.E. majority of what is in the pot. - Rice Hulls: a perlite substitute. Cannot grow in compost: salt concentration is too high and will burn plants. Containers: - plastic trays, containers, peat pots (disintegrates), jiffy plugs, used, creative
Transplants
a plant grown in one place (usually a container) to a certain stage before planted in another place. Goal: to produce vigorous plants ready to be planted in the garden. -Can avoid problems of seed emerging. -You can more closely control depth of planting. - Seeds will germinate under ideal conditions. - Extends growing season (early start, later finish)
assassin big

animals, insects, microorganisms Augmentation: increase pop. through purchase and release ladybugs Conservation: increase existing pop through conservation and other means
Red vs. Far Red Light
avoid spinly plants. (made in dark light, sick) PAR 400-700nm - controlling the red to far red light ratio is a means of controlling seedling height. - incandescent lamps, low R:FR ratio, frequently lead to stem elongation. - fluorescent light sources, high R:FR ratio, produce short and compact plants. - use fluorescent lights: on for 12-16 hr/day No farther than 4inches above plants. - one cool-white and one warm-white tube. OR full spectrum grow lights. Bottom heating with cool lights is the way to go. Avoid: cool temps, dark conditions, too much water. (cover with humidity dome to maintain 1st water level) - if seedlings/young plants dry out, they die.
Cabbage
bigger isn't better. - Cancer fighting compounds -Cardiovascular benefits Red foods are good for your heart - french paradox. - Protects against Alzheimer's disease (red cabbage)

Resistant varities
some varieties may be less attractive to pest species or tolerate more damage than others. Plant size, shape, coloration, hair, cuticle thickness, and natural chemicals
When to water
the difference between knowing and thinking you know is checking. - Your finger- the best water made sensor made It may be okay for the first 1-2" inches of soil to be dry if below is wet. Timing: Water in the morning! - Deeply and infrequently. Big root systems. Water application: no over head irrigate. BEST: DRIP IRRIGATION. or hand water.
Hardening off Transplants
the process whereby transplants stop growth and develop greater tolerance to the weather so they can survive being planted into the garden. - critical for both commercially grown transplants and transplants that you grow on your own.
A disadvantage to raised bed gardening: Increased plant density may increase some pest concerns, especially foliar diseases.
