Seeds Myself
 You can save money
 For a $2 packet of seeds there is a possible of getting 10-1000
 Swapping with fellow gardeners
 Saving your own seeds
 You have control.
 You know that you won’t be bringing something unwanted home
 You get more variety
 The enjoyment of seeing your seedlings emerge from
the soil
Before You Start
 Determine how much to grow
 What you want to grow
 Varieties should be selected by:
 Size
 Color
 Growth Habit
 What zone you are in
 Determine if you want:
 Heirlooms
 These are old, open-pollinated cultivars
 Hybrids
 This is a cross between two different plant varieties to get the
attributes of each variety
 If you see F1 it means it is a hybrid
Acquiring & Storing Seeds
 Acquiring
 Buy from a reputable seed company/catalog
 Storing
 Keep any left over seed in the packet it come in
 Store in a tightly closed jar or container

How to Help the
Seed to Germinate
 Scarification
 Stratification
 Soaking
 Light
 Dark
Tools Needed
Small Sharp Paring Knife
What is it?
 To remember what scarification means just think of the
word “scar”, which is what you are doing to the seed
 Happens naturally when a bird swallows the seed and
then passes it through the digestive system
 Not all seeds need scarification. The following website
is a good reference
How To
 Nick the seed with the paring knife or scratch the
surface of the seed with the sandpaper
 All seeds don’t need this method and you may kill them.
Refer to for a list of flowers and
vegetables and how to treat them
Flowers That Need Scarification
 Hollyhock
 Angels Trumpet
 Moon Flower
 False Indigos
 Canna
 Morning Glories
What is Stratification?
 Stratification is when a gardener purposely chills the
 Certain seeds have a way of protecting themselves from
germinating too early or too late.
 The only things you will need for this method is a Ziploc
bag a marker, and your seeds.
 Make sure to label the bag with what type of seed and
the date that it is to be removed from the refrigerator
 Seal the bag and place it in the refrigerator.
 Make sure it the bag is sealed or the seeds will dry out and
will not germinate

 Snapdragon 4-6 wk
 Columbine 2-8 wk
 Coneflowers 3-6 wk

 Cardinal Flwr 10 days
 Pansies 4 wks
 Salvia 1 wk
 Mainly the smaller seeds need light to germinate
 Do not plant seeds deep
 Place seeds on surface of soil and mist with spray bottle
 Cover with plastic and place in sunny spot
 Check seeds daily
 Once white roots or leaves are seen remove the plastic

 Statice
 Seeds that require soaking usually have a tough seed coat
 You can also soak seeds to check on germination rate
 Place the seeds you want to soak in a small bowl
 Let the seeds soak for the appropriate time
 If seeds need to be soaked for more than 12 hrs.
change water every 12 hrs.
 When done soaking pour off water. Coffee filters
work great for this
 Plant immediately

Seedlings Have Germinated
Now What??
Seeds Germinated
Now What?
 When sprouts appear move the seedlings into bright
 They need 14-16 hrs of natural or fluorescent light to keep from
becoming leggy
 Keep away from drafty windowsills
 Once the true leaves appear, water with a half-strength
solution of fertilizer
 You can use a water-soluble, all purpose plant food
 Gradually increase strength over time
 Seedlings should be thinned to at least 1” apart or
transplanted into individual pots
 Soil borne disease that attacks the seedlings as they
germinate causing them to collapse
 Stem turns brown, but leaves stay green
 Prevalent in warm, moist, muggy conditions or when
seedlings are sown too thickly.
 To prevent
 Use only clean pots and seed trays
 Use a soil-less mix that is moist but not over wet
Transplanting to Garden
 Plants will need one to two weeks hardening off
 This is to acclimate the plants to the outdoors
 Start by setting them out for a few hours at a time in a
protected, semi shady location
 Outdoor temperatures should be 45 degrees or warmer
 Gradually increase the time and exposure to direct sunlight
 Transplant seedlings to the garden in the late afternoon
or on a cloudy day and water
