Class Introduction

Please keep your talking to a minimum, allowing you and your neighbors to get the full value of the class. Please raise your hand if you have any questions, but try to hold them for later - have faith in my agenda. Too many questions get us

• ff track and delays the class.

steps

Start from the Ground Up

Soil pH

X

• Rainfall increases soil acidity
• Add lime to raise pH
• Add sulfur to lower pH

Importance of N-P-K: Macronutrients

• Nitrogen (N): Green growth
• Phosphorus (P): Root growth and flower/fruit

production

• Potassium (K): Overall plant health

Micronutrients

• Calcium (Ca), Magnesium (Mg), Molybdenum

(Mo), Boron (B), Copper (Cu), Manganese (Mn), Zinc (Zn), Chlorine (Cl), Iron (Fe), Nickel (Ni)

• Needed in trace quantities, too much can hurt

plants more than it can help

• Regular additions of
• rganic matter, such as

compost, usually meets micronutrient needs

Purchase Good Top Soil If you Need to Fill New Beds

50/50 BLEND OF THESE TWO

Mulch on Paths for Weed Suppression

Organic Amendments

• Feed your soil like you feed your body
• Cannot "Miracle Gro" soil into good health
• Vegetables are fast-growing plants
• Need more fertilizer than perennials because you

are harvesting (taking away nutrients)

• Always amend beds before planting
• Soil test will reveal deficiencies and

make amendment recommendations X

Every Garden Should Have a Compost Pile and Worm Bin

Bed Amending Recipe

For a 50 square foot bed:

• 1 wheel barrow homemade compost OR

1 bag Gardner & Bloome Harvest Supreme

• 2 quarts G&B 4-6-3 Tomato, Veg, & Herb Fertilizer
• 1 quart pure Worm Castings

Note: Double up if your soil is poor (very sandy or heavy clay)

Bed Amending Step by Step

• Sprinkle all amendments evenly on

top

• Turn over soil using a spade fork
• Rake smooth

Our new favorite "Magic Bullet"

Mykos Mycorrhizal Fungi

• Sprinkle on root ball as you plant
• Beneficial "live" fungus that attaches and

spreads with rootzone

• Keeps plant from being infected by soil borne

diseases

• Helps plants "communicate" to each other when

under insect attack and produce enzymes to ward off attackers

• Helps plants use water more efficiently

Sowing Requirements for Summer Veg

Must Direct Sow Either Must Transplant Carrot Greens: Lettuce, Mustards, Arugula, Chard, Kale Tomato Beet Squash, Zucchini, Melon, Cucumber, Pumpkin Pepper Radish Onion Eggplant Turnip Corn, Bean

Direct Sowing Root Vegetables

• Sow seeds 1 per square inch
• Cover with 1/4 inch of soil
• Don't let surface dry out
• Use floating row cover
• Use thinnings as flavorful,

unusual garnish

STRETCH BREAK!

Solanaceae Family: Nightshades

Tomato

• Start from seed in Feb or

March or buy transplants instead

• Plant outside April/May
• 2' - 3' spacing
• Lots of fertilizer
• Trellis with tomato cage

Pepper & Eggplant

• Start from seed in Jan or Feb or buy

transplants instead.

• Plant outside late April or May
• 18" spacing

bamboo, or trellis netting

Growing Potatoes In Pots

• Buy certified
• rganic seed

potatoes

• Link to potato seed

supplier in email

• "Chitting" seed

potatoes: Lay out seed potatoes by sunny window until they sprout (if they aren’t already)

Growing Potatoes In Pots

• Use new 15 gallon pots, or sterilize used 15 gallon pots

with bleach solution

• Use sterile (new) potting soil
• Fill pots with 2" soil, add 4 - 5 potato pieces, cover with 2"

soil

Growing Potatoes in Pots

• Once shoots reach 8 - 10",

cover up to top leaves with soil

• Continue until they grow out
• f the pot
• Keep watered
• Once potato flowers and dies,

potatoes are ready to harvest

• Potatoes require full sun

• Many different

varieties and colors

• Requires tall trellis

○7' tomato cages ○String trellis

• 6" spacing
• Edible flowers
• Longer season

than bush beans

Pole Beans

Bush Bean

• 1' - 2' tall
• Green or Purple
• 8" - 10" spacing
• Small tomato cage, trellis netting, or

bamboo

• Edible flower
• Shorter season

Fava Bean

• 4' - 5' tall
• Cover crop
• Edible leaves - harvest tops

to encourage branching

• Edible flower
• 1 foot spacing
• Individual bean must be

shelled too

Let’s talk about Cucerbits

Melons & Summer Squash Cucumbers & Winter Squash

Melons

• Vining plant
• 1' spacing

Issues:

• Wet soil contacting

skin makes it susceptible to pests

• Don't like cold

soil/low nighttime temps Solution...

• Wait to plant until May
• Lay clear or black UV plastic over amended bed
• Cut "X"s in plastic to plant through
• Must have drip irrigation under plastic

'Hearts of Gold' Cantaloupe 'Eden's Gem' Muskmelon

Sugar Baby Red Watermelon Italian Honeydew

Cucumber

• Use trellis to grow cukes on or

let sprawl on ground (best to use plastic on bed to prevent fruit contacting ground)

• Lemon (Yellow), American

Slicing (Green), and Pickling

• 8" spacing
• Careful when transplanting -

don’t disturb roots or tear rootball.

Summer Squash vs. Winter Squash

• Large, bushy plants
• 2' spacing
• Grow very quickly - harvest
• ften during

season's peak

• Soft, edible skin
• Eaten fresh
• Large, long vining plants
• 1' spacing
• Harvest entire crop at end of

season, when tendril closest to fruit has dried up

• Hard skin
• Usually stored, eaten in

fall/winter

Irrigation

• Drip irrigation is more efficient than hand watering, soaker

hoses, or sprinklers

• Easy to install from your spigot
• Water early in morning if you can
• Don't rely on a timer - check each bed daily
• Take our Irrigation class next week

Gopher Trapping - Not Wire!

Deer Fencing

• Necessary to keep

them out

• Sprays don’t work

and take up too much time.

• 8' tall
• Attach to T-posts
• Deer will eat

everything!

Organic Pest Control

• Be an observant gardener - inspect leaves on regular basis
• Act on an issue immediately with appropriate controls before the

population gets out of control

• Organic controls must be reapplied
• Remove overpopulated plants and dispose of responsibly
• Use preventative methods

○ Proper spacing in between plants for airflow ○ Biodiversity ○ Proper watering with irrigation ○ Weed control

Aphids

• Green, Black, Red, Grey
• Watch for curling leaves
• Organic pesticide: Pyrethrin, Safer Soap,

Neem Oil

• Organic preventative: Garlic spray
• Beneficial bugs: Lacewing, Ladybug
• Give infested leaves to chickens

Squash Bug

• Attack all cucerbits, not

just squash

• Smell like bananas when

squished

• Hand pick early in season

before population explodes

Cucumber Beetle

• Striped or spotted
• Carry diseases
• Pyrethrins
• Hand pick
• Attracted to yellow flowers

Slugs, Snails, Earwigs, and Pillbugs

• Sluggo Plus is organic and

effective

• Hand pick late at night with

flashlight

Beneficial Bugs

Lacewing Soldier Beetle Lacewing larva and aphid Soldier beetle larva

Beneficial Bugs

Ladybird beetle Honeybee & Bumblebee Ladybird beetle Larvae

Flat Sowing Instructions

• Sow 3 cells of each type of vegetable/fruit = 16 per flat
• Don't poke seeds into soil or make a divot
• Only use as many seeds as what is written on seed

canister/packet

• Space seeds apart evenly
• Half labels, pencil only, push label in so it contacts

bottom of flat

• Pass in circle, clockwise
• Seeds will go around several times
• Only have 1 container open at a time
• Put lids back on tight after selecting

Seedling Tray Care

• Flat care instructions will be in links list email
• Water flat 3 times and cover with plastic
• Optimal temperature: 75 degrees
• Remove plastic cover once 1 seed sprouts
• Regulate heat mat with instant-read meat thermometer or soil probe

with thermostat

• Heat mat might not need to be on during day

Seedling Tray Care

• Bring sprouted 6-packs outside in morning and inside at night
• Once sprouted, do not overwater to avoid rot
• Transplant into small containers once seedlings show several sets
• f leaves, and outside in light all day and night.
• Transplant deeper than they were before once you put out in a bed.
• Use G&B Potting Soil for potting up
• Fertilize seedlings with worm casting tea

Supplemental Fertilizing

• Plants will need additional fertilizer, particularly if yellowing
• Best fertilizer: Worm Casting Tea
• Recipe: Big handful of castings in a 5 gallon bucket of water
• Let sit for two days
• Stir and dilute X2
• Strain through cheesecloth or FRC or strainer and apply to plants

with a watering can or garden sprayer

• Do twice a month during growing season
• WCT has been shown to: increase fertility, reduce incidence of

disease and reduce bug stress
