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:

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)

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

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

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; 3 years for
most other crops
– When in doubt, use new seed
• Inoculate seeds for improved plant
health & yields:
– Myco Seed Treatment (mychorrhizal fungi-covers
for veggies and legumes; Fedco $50)
– Garden Combination Legume Inoculant $5
(Rhizobium bacteria - Johnny’s and Fedco)
PLANTING TIMES
• Plant crops considering frost dates
• Frost dates in CT (2001-2010 data):
– Last frost date: 3rd week of May
– First frost date: 1st week of October
• Plant crops at their most favorable time
of the season:
–Weather
–Insect & disease cycles
• ex: radishes – insects
• ex: cucumbers – disease
PLANTING TIMES
● Highs for that day
● Lows for that day
▬ Rolling Average High

PLANT SPACING AND METHODS
Direct seeding vs. transplanting
• Benefits of Transplanting:
–better care of seedlings
–jump start over weeds
–can handle rougher ground
–no thinning
–can transplant into mulch
PLANT SPACING AND METHODS
Direct seeding vs. transplanting
• Drawbacks of Transplanting :
– possible transplanting shock/setback
– some plants do not transplant (carrots, beets)
– need supplies (potting soil, pots or soil block
maker)
– have to plan ahead (schedule)
• Buy seedlings from reputable, disease free
source
Seeding soil blocks
Seedlings coming up
PLANT SPACING AND METHODS
Direct Seeding
• Start with well prepared seed bed
• Use correct seeding rate (ref: our chart)
• Weed & water regularly, especially when
plants are small
• Thin if necessary (beets, carrots particularly
important)

Questions?
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
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 ×

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. We normally do a minimum of 300 ft2 when using
a wand at 6 gpm flowrate

Questions?
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

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

–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
