N Sun Exposure Understand Your Site • Where is North? • Are there trees around your garden site? • What will their impact be? • Are you on a slope? Assessing Garden Placement • Determine what your plants will experience • Face the sun at noon • Fall backwards • Stretch arms to side – E/W Sunrise at equinox E W S Sun Exposure We’ll Look at arc and sun angle for: • June 21 – longest day of the year • April 21/Aug 21 – 2 months earlier/later • Feb 21/Oct 21 – 2 months earlier/later • Dec 21 – 2 months earlier/late – shortest day of the year N Sun Exposure June & July • Sun swings a large arc • 15 hours of sun, 5:15am-8:30pm • Sun is almost directly overhead (72o) at midday • Trees East & West will have the greatest impact on your planting E W S 90 80 70 60 50 40 30 20 10 0 270 West 180 90 South East Altitude (deg) Growing Info • Most crops love June, but some crops won’t like the heat of July June 21st Summer Solstice N April→May & Aug→Sept • Sun swings a large arc • 13.5 hours of sun • Sun is relatively high (61o) in the sky at noon • Again, trees East & West will likely have the greatest impact on your planting Apr 21st / Aug 21st E W Growing Info • Excellent time of year to grow • Be careful of frosts 270 through mid-May West S 90 80 70 60 50 40 30 20 10 0 180 90 South East Altitude (deg) Sun Exposure N Sun Exposure Feb→Mar & Oct-Nov • 11 hours of sun • Trees in the arc from SE to SW will have the greatest impact on your growing • Sun low in the sky (38o) E W S 90 80 70 60 50 40 30 20 10 0 270 180 90 Altitude (deg) Growing Info • Slow growth, but can get a jump in the spring, and crops in the fall will hold on • Spring and fall will require plastic Feb 21st / Oct 21st N December → January • Only a small arc around due South is critical • 9 hours of sun • The sun is very low (25o) in the sky and trees to the South must be far away from the planting area Growing Info • Only a few plants will grow at this time of year; minimal growth occurs 270 • Plastic covers required December 21st Winter Solstice E W S 90 80 70 60 50 40 30 20 10 0 180 90 Altitude (deg) Sun Exposure Sun Exposure Hours of Sunlight at different times of the year and different distances from a tree line Distance (in feet) from 60 feet Tall Trees X feet 50 100 150 200 300 400 2000 max 21-Feb / 21-Apr / 21-Dec 21-Oct 21-Aug 21-Jun Hours of Sunlight Received when X feet from 60' Tall Trees 0 0 4.5 5.5 0 4 8 9 3 6.5 9.5 10.5 5 7.5 10.5 11.5 6.5 8.5 11.5 12.5 7 9 12 13.5 8.5 10.5 13.5 14.5 9 11 13.5 15 Solar Radiation Sun Exposure • Day length & angle of incidence impact • ⅓ to ½ energy available cold months relative to summer • Note that March & April are better than October Average Daily Radiation on Horizontal Surface (kWh/m2/day) High Growth Months 7 6 Slow Growth Months 5 4 3 2 1 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Sun Exposure Take home messages • If trees surround your garden and are 50 feet away or less – hot weather crops will not thrive • For late spring / summer season, focus on cutting trees East and West of garden • If you want to extend season into the fall, cut trees to the south • March and especially April get plenty of sun – plant early! • If shade is a fact of life: – check out Mother Earth News – Best Shade-Tolerant Vegetables By Colleen Vanderlinden http://www.motherearthnews.com/organic-gardening/shade-tolerant-vegetables-zm0z11zsto.aspx Sun Exposure Questions? SOIL FERTILITY • What good soil looks like: –granulation (crumbly, stable), aeration (porous), water infiltration –Organic Matter, soil cover, soil biology are key • Soil tests: why, when, how to take? –Why: mineral levels, humus, indicative of biological activity –Soil contamination – Lead, Arsenic, other heavy metals? Test if suspected. SOIL FERTILITY • Soil tests: why, when, how to take? –When: fall, before ground is frozen • Consistency is very important –How: Soil probe and follow instructions –Where we go: Crop Services International (CSI) –How often: yearly for first 3 years, then every other year SOIL FERTILITY • Interpreting soil test results –Sample soil test report – Recommendations & consultation with CSI • Follow-up: –Order soil amendments from Fedco –Plan and follow a basic fertility program SOIL FERTILITY Basic fertility program: what to apply, when 1. Broadcast rock powders to balance minerals 2. Compost for organic matter and to sustain biological activity 3. Liquid fertilizers: fish and seaweed to sustain biology SOIL FERTILITY • Compost: important for organic matter and to stimulate biology –On new ground, start with ~1in. –Decrease in future years as humus level increases –Too little or too much compost can be problematic – Blue Slope 860 642 7084 – pick up with your own vehicle or small deliveries possible (delivery ~ $50 for 4yard truck) – Beltane Farm 860 208 2887 / Kato Corner 860 537 3884 SAMPLE SOIL TEST REPORT SAMPLE SOIL TEST REPORT SAMPLE SOIL TEST REPORT SAMPLE SOIL TEST RECOMMENDATIONS SAMPLE SOIL TEST RECOMMENDATIONS SAMPLE SOIL TEST RECOMMENDATIONS SOIL FERTILITY Questions? Animal Management Fencing needed for… • • • • Deer Woodchucks Rabbits Raccoons Other furry pests… • Rodents: mice, moles, voles, shrews Animal Management Deer – What you need – 8 feet fence recommended – 6-7 feet may work for small garden – Posts • Cedar • or Metal – Fencing • Plastic • or Metal – Gate Animal Management Cedar Posts • buried 2½-3ft – (need 11ft pole) • Space 25ft apart • Posthole digger & metal bar best for digging hole • Time: ½ hour per hole • Cost: $15-25 per post • Where: Lou Chilly, Chaplin 377-0066, or craigslist Animal Management Metal Posts • likely need two poles bolted together – bolt together after pounding in the ground • Support is needed, rope or cable to the ground to a metal bar – These supports are annoying (trip over, mow around) Animal Management Metal Posts (continued) • Post pounder needed – sledge hammer destroys the post for bolting together • • • • Space 10-15ft part Time: 5 minutes per post Cost: $8 per section (two metal posts) Where: Mansfield Supply, Willard's, Thompsons, Mackeys, John’s scrap metal Animal Management Fencing • Plastic (available from Mansfield Supply, Thompsons) – Advantages: • very inexpensive ($30 for 100ft X 7ft) • Fairly easy to install – Disadvantages: • deer may rip through it, can’t see it at night • Buttons of shirts always getting hung up on it Animal Management Fencing (continued) • Metal – chicken wire or other metal fence (available from Thompsons) – Advantages: • Deer won’t get through • Keeps out woodchucks (if buried) – Disadvantages: • More expensive and harder to install Animal Management Gate – Options • Make out of wood – Use chicken wire or finer mesh – Wood available from Willards, Mansfield Supply – Chicken wire or mesh from Mansfield Supply, Willards • or Chain link – Buy used from John’s scrap metal, off of Rt. 6 (Columbia) • No gaps at bottom, keep out woodchucks – Sill to prevent from going under Animal Management Woodchucks, Rabbits, Raccoons • Woodchucks – Can be devastating to a garden • Rabbits – moderate pest, much less than woodchuck • Raccoons – known for eating corn (and killing chickens) Animal Management Woodchucks, Rabbits, Raccoons • Keeping them out – Woodchucks will dig under fences • Need to bury chicken wire 1 ft deep around garden – Woodchucks and Raccoons will climb over • Wire should extend at least a few feet above ground and “sewn” with upper fence – Chicken wire from Mansfield Supply or Thompsons – Other Options for Woodchucks • Flush them out of their hole, deluge of water • Have-a-Heart traps • Easy to shoot with a .22 rifle Animal Management Rodents: Mice, Moles, Voles, Shrews • Can be devastating to roots, tubers and even spinach • Solutions – Cats - we have little to no damage since getting cats • They must have access to the garden – Snap traps at rodent hole entrances • Dig a small trench at entrance holes • Use wooden traps with yellow “cheese” • Bait with peanut butter, re-bait every few days Animal Management Questions? Soil Preparation From Sod to Garden Soil • Goals – Kill sod, including quackgrass – Eliminate thick fibrous roots – Loosen subsoil • Different Methods – Double-digging – Mulch Coverage – Clear Plastic Burn – Mechanical Tillage – Raised Beds Soil Preparation Double-digging • Process – Dig a trench the width of the garden, one foot deep, placing soil on surface or in wheelbarrow – Loosen soil at bottom of trench using spading fork – Expand the 1 foot deep trench, putting the new soil from the top 1 foot into the previous trench • Flop over sod, putting at bottom of 1 foot trench • Mix in compost at the same time – Continue for the entire garden area Soil Preparation Double-digging (cont) • Pros – Best method for the long-term success of your garden – Can plant soon after • Con – A lot of work • Sources: John Jeavons: How to Grow More Vegetables Soil Preparation Mulch Coverage • Process – – – – – Put 1 inch layer of manure or compost over garden area Put 12 inches of mulch: leaves, hay or straw over garden area Weed whenever something starts growing through mulch Wait one year Remove mulch and plant (do not incorporate mulch!) • Pros: – Very healthy for the soil – Minimal effort • Cons: – Takes one year – Sub-soil not loosened Soil Preparation Clear Plastic Burn • Process – – – – Lay clear plastic over garden area Weigh down edges, tighter the better Wait months Loosen using a shovel, till lightly or mulch over winter • Pros: – Easy – Kills quackgrass • Cons: – Need to do at the hottest time of the year – Sub-soil not loosened Soil Preparation Mechanical Tillage • Process – Put 1 inch layer of manure or compost over garden area – Till garden with roto-tiller – Wait 4 weeks, depending on soil structure, till again – Loosen soil with rake and Plant • Pros – Its fast and easy – Good growth first year – Breaks up sod • Cons – Causes soil compaction and damages soil structure – Sub-soil not loosened – Need to rent or buy tiller, or hire someone Soil Preparation Raised Beds • Process – Build raised bed structure to desired height (8 to 12 inches) – Width of 3’ reasonable, length as much as desired – Bring in quality soil: mix of fill, topsoil and compost/manure • Pros – Excellent for wet soils, raised beds will stay drier – Can plant immediately – Weeds won’t encroach – Slightly less bending • Cons – A lot of work – Need to find uncontaminated soil – Bed barriers will rot, or you’ll need to use pressure treated wood Soil Preparation Questions? PLANT AND SEED SELECTION • How many plants and of what type? –consider growing area –yields –planting & harvest schedules –crop needs (trellising, picking, covering) –pests & disease • Make a week-by-week planting schedule • Plan to feed your family year-round from your garden 7/15(10/22) squash, winter S21 S20 S19 S18 S17 S16 S15 S14 S13 S12 S11 S10 S09 S08 S07 S06 S05 S04 S03 S02 S01 C22 C21 C20 C19 C18 C17 C16 C15 C14 C13 C12 C11 C10 C09 C08 C07 C06 C05 C04 C03 C02 C01 Week-by-week planting schedule (field and soil blocks) 4/16(6/17) lettu 10-Mar 17-Mar 24-Mar 7-Apr 9/23(1/0) covercrop 4/9(7/20) 9/23(1/0) 7/7(10/9) covercrop 4/9(7/20)31-Mar squa carrots carrots 1-lettuces(E06,E06) 2-spinach(E04-05) 1.5-carrots(E10-11) 1.5-beets(C04,J06) 5-kale(C01-03,S01-02) 2-carrots(E07-08) 3-beets(E09,W05,W09) 0.67-arugula(N04,N04) 2-carrots(C21,S21) 9/23(1/0) covercrop 9/6(1/0) covercrop 4/16(6/17) lettu 5/7(8/14) 7/30(9/20) cucumbers,1.5-radishes(E11,W10) slicers 7/30(9/18) cucumbers, picklercarrots 4/4(7/16) carrots 1.4-lettuces(W06-07) 2-claytonia(W04,W11) 5-peas, snap(Y01-03,Z01-02 1.33-spicy mix(N04,S04) 2-cabbage(Y04-05) 2-carrots(W08,X03) ) 2-carrots(S20,X22) 4-broccoli(Y06,Z04-06) 9/6(1/0) covercrop 4/22(7/31) carrots 9/6(1/0) covercrop 7/7(10/9) squa 4/22(7/31) carrots 2-spinach(J01,Z03) 1-lettuces(Y06) 10-onions(Y07-11,Y11,Z07-1 26 Total Beds 7/30(10/12) squash, summer & z. 7/30(10/12) squash, summer & z. 9/6(1/0) covercrop 5/7(1/0) carrots 9/6(1/0) covercrop 5/7(8/14) carrots 5/7(11/1) parsley 9/6(1/0) covercrop 5/7(8/14) carrots 7 Total Beds 10 Total Beds 5/17(9/19) eggplant 12-Maycrop, dates) Field Map (bed ID, 5/17(9/19) eggplant 1.25352112676056X2-lettuce 2-eggplant(C14-15) 5-May 3-carrots(C16-17,C20) 2-arugula(N07,S16) 5/18(9/20) eggplant 2-carrots(S17,Z24) 5/17(9/19) eggplant 1-bok choy(W29,W29) 5/18(9/20) eggplant 5/18(9/20) eggplant 5/18(9/20) eggplant 7/5(10/4) cabbage 2-Jun 9-Jun 1.8-arugula(Y29,S03) 2-basil(E11,W11) 7/5(9/12) broccoli 1.17307692307692X2-brussel 2.5-sweet potatoes(Z07-11) s sprouts(S03,X25) 7/5(9/12) broccoli 5/22(6/30) arugula 2-basil(B01-02) 5-okra(C32-36) 7/17(9/23) broccoli 4/4(7/14) beets 3-beets(Y27-28,Z27) 1-spicy mix(Z28) #N/A 4/8(11/29) kale 4/8(11/29) kale4.5 Total Beds 30.25 Total Beds s(N06,X05) 6-lettuces(N08,N10,N12,N14 5/18(9/20) eggplant 1.6056338028169X2-cucumber ,N16,N18) s, slicers(X05,X07,X07,X07) 2-eggplant(S14-15) 5/18(9/20) eggplant 1.39171259440702X2-cucumbe 1-quinoa(Y35-36) rs, 5/18(9/20) pickler(X09,X09,X11) 8-eggplant(C10,C10-13,S10eggplant 2.01449275362319X2-squash, 13) 5/18(9/20) eggplant 5/18(9/20) eggplant summer & z.(X13,X15,X15) 7-sweet potatoes(Y12-14,Y1 7/5(10/4) cabbage 4,Z12-14,Z14) 38.5307205552154 Total Beds C 7/5(10/4) cabbage S 7 Total Beds 7/5(10/4) cabbage 6.5 Total Beds 5/17(9/19) eggplant 7/5(10/4) cabbage 7/5(10/4) cabbage 7/5(10/4) cabbage 5/17(7/12) lettu 7/7(10/9) squa 5/17(7/12) lettu 23 Total Beds 7/7(10/9) squa 19-May #REF! 1.5X2-tomato, field(E24,E2 10/29(1/0) gar 1.5X2-tomato, heirloom(E26 10/29(1/0) ,W2 gar 2X2-tomato, cherry(W26,W28 10/29(1/0) ,W2 gar 1X2-tomato, heirloom(W30,W 10/28(1/0) gar3 1X2-tomato, paste(W32,W32) 10/28(1/0) gar 2-beans, bush(Y15-16) 10/28(1/0) gar 10/28(1/0) gar 16-Jun 23-Jun 2-potatoes(Y21,Z21) 3-beans, dry(K01,K01-02) , summer & z.(N07,N0 7/5(9/12) broccoli 10/28(1/0) gar 3-lettuces(B03-05) ∞ 3-corn, grain(K02-03-03) 2X2-cucumbers, pickler(N09 5-carrots(C26-30) 3-beans, dry(K04,K04-05) ,N1 7/5(9/12) broccoli 5/22(6/30) 10/28(1/0) garli arugula 2-arugula(E04,F10) 4-corn, grain(K05-06-07) 1X2-cucumbers, slicers(N13 2-lettuces(F11,F14) ∞ broccoli2X2-celeriac(K11,N01) 7/17(9/23) 10/24(1/0) garli 4/4(7/14) beets 2-spicy mix(X33-34) 2X2-squash, summer & z.(N0 3-beans, bush(K08-10) 3,N05,N05) 4/8(11/29) kale 10/24(1/0) garli 2-beets(X35-36) 1X2-cucumbers, pickler(N07 4/8(11/29) kale 10/24(1/0) gar ,N07) 0.478260869565217X2-squash 10/23(1/0) 4/8(11/29) kale 21 Total Beds 29.9565217391304 Total garlic Beds PLANT AND SEED SELECTION • Sequential plantings for continual harvest • Hybrid vs. Heirloom: taste, productivity, vigor, seed saving • Seed Suppliers (none of these carry GM) –Johnny’s Selected Seeds (johnnyseeds.com) –Fedco (fedcoseeds.com) –High Mowing Organic Seeds (highmowingseeds.com) PLANT AND SEED SELECTION • Seed Storage/Life – Cool, dry place (freezer) – Onions, parsley, parsnip – 1 year;

WATER • How much do plants need • When do plants need it • How to calculate watering times WATER • Our rule of thumb: 1 inch water/week (rain + irrigation) • Soil observation is important • Lack of water or too much water both cause serious problems • Rain gage strongly recommended (Johnny’s or Fedco) – proper placement is important – What a weather station in Windham receives can be much different WATER • Keep track of rain fall and watering amounts • Critical watering times: –At seeding and transplanting –During germination and until plants develop a mature root system (2+ weeks) –Other growth stages: plant dependent (ex: potatoes, beets, cucumbers) WATER • Straw or hay mulch prevents soil from drying • Irrigation: –overhead (watering can, wand or sprinklers) –drip tape –buried soaker hose • Watering should be done with a gentle shower! • Water in early morning – watering during hotsunny part of day wastes water and crusts soil WATER • Watering in the evening can cause problems with leaves being wet overnight • Keep water in the root region. Wet leaves for long periods can lead to disease • Optimize frequency and amount of watering – Not too much, not too little, not too often… • Know the flow rate of your watering device: fill a 5gal bucket and time how long it takes. • Record how much water you’re putting down each time you water. WATER Example of Watering Records • Keep track of rain • Plant date • When it needs to be watered • crop • Target 1” per week • bed Crop carrots beets tomatoes D F O Bed(s) Rain E12 X01 GH O O F S July S M T W H F S S M T W H F S S M T W 29 30 1 .35 2 3 4 5 P √ 6 7 8 .5 P 9 10 11 12 13 14 15 16 17 WATER Watering • ¼ inch of “rain” at one time is reasonable – More than this can be too much – less than this is watering too often • Using a Watering Can (calculations) – For a ¼ inch equivalent of rain: • Water Required (gallons) = Area (ft2) X (0.16) – Example • Area: 10 ft2 • Water Required = 10 X (0.16) ≈ 1½ gallons gallons required = 𝐴𝑟𝑒𝑎 𝑓𝑡 2 × 1 4 1 𝑓𝑡 𝑖𝑛𝑐ℎ 𝑟𝑎𝑖𝑛 × 12 𝑖𝑛𝑐ℎ𝑒𝑠 × 1 𝑔𝑎 0.134 𝑓𝑡 3 WATER Watering - Using a Wand • For a ¼ inch equivalent of rain: – Time Required (minutes) = Area (ft2) X 0.16 / wand flowrate (gpm) – Need to calculate wand flowrate • Fill a 5 gallon bucket with wand, calculate gallons per minute (gpm) • Example – – – – Area: 100 ft2 Wand Flowrate: 6 gpm Time required = 100 X 0.16 / 6 ≈ 2½ minutes Note: using a wand on less than 100 ft2 is likely to much water in to short a time.

WEEDS • Weed regularly • Don’t let the weeds go to seed • Do not use herbicides • Pull weeds out by the root or cut below the soil line WEEDS MULCH • Helps control weeds • Straw is better than hay because it won’t drop seeds • Hay is better than bare soil • For heat loving crops (tomatoes, peppers, eggplant, cucumbers, squash), wait until soil has warmed up (70F, early summer) before mulching WEEDS HOEING • We use wheel hoe, hand hoes, standup hoes, grub hoes, cobra weeder • Works well when weeds are small, and with proper technique (practice!) • Helps soil aeration especially if you have crusty soil or soil compaction • Too much leads to oxidation of organic matter WEEDS HAND WEEDING • Takes longer than hoeing but can be more effective and longer-lasting • When we direct seed a bed, we hoe it once or twice when the plants first come up and weeds are small, and any weeding after that is by hand WEEDS • Keeping the garden weed free pays back in future – weeds will gradually become less of a problem • Certain periods are more challenging / critical than others • Plan to be on top of weeds during growth spurt in early summer, and when plants are small WEEDS Questions? INSECTS Beneficials • Pollinators - needed by many plants • Control pests by eating or parasitizing them • Need water and source of nectar Pests • Pests are outnumbered by beneficials and other insects INSECTS BENEFICIALS • Plant herbs and flowers to attract them (dill, carrot, queen anne’s lace, cosmos, mustard family, cilantro, basil, clovers, etc.) • Let them go to flower! • Some beneficials we see: different kinds of wasps, tachinid flies, praying mantids, lady beetles, assassin bugs, spiders, lace wings, ground beetles, etc. INSECTS Common Pests Colorado Potato Beetle Flea Beetles Imported Cabbage Butterfly Tomato Horn Worm Cross Striped Cabbage Worm Tomato Horn Worms with and without parasitic wasps Beneficial Insects on dill: Honeybee and wasps INSECTS PESTS: • Flea beetles on brassicas – cause problems in spring; – can be significant problem on eggplant – use row covers – hand pick when wet/cool (tedious) • Colorado Potato Beetle: – regular inspection and hand picking – recognize and kill adults and larvae INSECTS PESTS: • Tomato horn worm – regular inspection – hand pick except for parasitized ones • Cucumber beetles, squash bugs, bean beetles – regular inspection, hand pick, destroy eggs • Root Maggots – Radishes, turnips – Worse in spring – shift planting to fall INSECTS PESTS: • Squash borer –find location and hand remove • Imported cabbage worm, cross striped cabbage moth –use row covers; –hand remove; –soak broccoli, cabbage, cauliflower heads in salt water after harvest INSECTS Pests • Leaf miners: –chard, beet leaves, less on spinach; –squish larva borrowed in leaves • Cutworms: –active in spring until June; –dig around plant with damage and kill the worm INSECTS Pests • Aphids: –may signal too much N –hand remove and/or wash off at harvest –Lady Beetles will eat them • Slugs –like moisture - maximize ventilation –hand remove INSECTS General Recommendations • Healthy plants are less susceptible to pests – make soil health a priority • Do not use pesticides (harmful to nontarget insects) • Identify pests and their different stages (eggs, larvae, adult) • Make sure you’re not killing beneficials or other insects INSECTS General Recommendations (cont.) • Schedule planting to avoid pest cycles • Mulch may harbor pests like slugs but overall we believe benefits outweigh drawbacks • Inspect plants regularly and keep garden tidy INSECTS Questions? COMMON DISEASES General Recommendations: • Crop rotation, soil fertility / health, and basic field hygiene minimize disease • Avoid disease prone times when designing planting schedule • Do not use fungicides or anything that harms soil life • Purchase plants from trusted sources COMMON DISEASES • Do not touch plants leaves when wet • Do not touch healthy plants after diseased ones. • Remove diseased plant parts from the garden. • Avoid fungal diseases with good air circulation. • Look into disease resistant varieties when purchasing seed. COMMON DISEASES Diseases We Experienced: • Cercospora: –beets, chard, carrot leaves –prolonged high humidity and heat are problematic (August) • Early blight & septoria on tomatoes: –avoid wet leaves –mulch –trellis to encourage good air circulation COMMON DISEASES Late Blight on tomatoes and potatoes: • Very serious - rapidly kills plants • Know where your plants come from • Avoid wet leaves, esp. overnight and during cooler periods (70F and lower) • Trellis tomatoes for good air circulation • Do not touch plants when wet/dewy • Remove diseased plants from field COMMON DISEASES • Mildews on cucumbers and squashes for plantings July and later. Plant early (June) • Mildews on Basil: plant no later than 1st week of June • Fungal diseases on lettuces: plant early and use disease resistant varieties Septoria / Early Blight on tomato leaves Cercospora on beet leaves Trellised tomato plants: support, air circulation, ease of harvest COMMON DISEASES Questions? THE HARVEST • Some vegetables need to be harvested promptly and regularly (ex: broccoli, tomatoes, cucumbers, okra). • Others are more flexible (ex: chard, kale, carrots, beets). • Lettuces, spinach, greens such as arugula, mustard, mizuna, bok choi and other brassicas will bolt in the spring if not harvested on time THE HARVEST • Some vegetables produce all season (kale, chard), others produce heaviest in a smaller window of time (cucumbers, broccoli, etc.) • Some veggies store for months under the right conditions (ex: root veggies), others only days. • Be prepared to do something with your vegetables (plan your harvest) THE HARVEST • Prepare meals around what’s in the garden (in-season cooking) • Use long-term storage techniques –freezing (blanching or not) –canning (hot water bath vs. pressure canning) –dehydrating (dehydrator or oven) –fermentation Short Term Storage Short and Long Term Storage Information Location fridge counter fridge fridge fridge fridge fridge fridge fridge fridge fridge fridge fridge fridge counter fridge pantry fridge fridge fridge pantry fridge fridge fridge pantry fridge fridge fridge fridge fridge pantry fridge pantry counter fridge fridge fridge Storage Method in plastic bag, loosely closed roots in water (NOT IN FRIDGE) in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, partly open in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, loosely closed in plastic bag, loosely closed store in jar, stems in water, loosely covered in plastic bag, loosely closed out of sun in plastic bag, loosely closed drain water from bag periodically in plastic bag, loosely closed out of sun store in jar, stems in water, loosely covered in plastic bag, closed in plastic bag, loosely closed in paper bag (need darkness) in plastic bag, loosely closed loosely covered (eat within 1 day) in plastic bag, loosely closed drain water from bag periodically in plastic bag, loosely closed out of sun lightly covered out of sun in plastic bag, loosely closed in plastic bag, loosely closed * For long-term storage there are other options, such as canning and freezing.
