2 - Cold Stratification
The next step is the cold stratification period. This step is where all the magic of nature occurs. In nature, most of the tree seeds fall from the trees in autumn.

Stratification can be artificially created with the help of a refrigerator. This can be necessary when trying to germinate seeds out of season, seeds that have been stored inside over winter or seeds of species that will not germinate naturally in your local climate.

Heat Stratification
For some species, the cold stratification process should be interrupted by a period of time called "heat stratification" - simply place the seeds in a bowl in your room, exposed to room temperature, for a period of time, ...

Cold Stratification will be used if...
you want to plant your seeds out of season
the seeds have been stored inside and out of the soil over the winter
you are using seeds that will not germinate in your local climate ...

Stratification is the process by which a seed breaks it dormancy and gets a cue to start germinating. Climate plays a major role in seed stratification.

~ - The process of preparing a tree seed for sowing by dispersing the seeds in sand and subjecting them to cold conditions, outdoors or artificially in a freezer or - refridgerator. This encourages germination.

Seed - you can grow trees from seed like other plants, however most tree seeds need ~ prior to planting. This is accomplished by keeping the seeds in a cold environment for a period of time.
Air Layering - Is a method of propagating a new tree from an existing tree.

For example, certain temperate species of tree like maples must undergo cold ~ before they are ready to germinate. Cold ~ simply means a cold and moist period, usually the winter months. In nature, these seeds fall off of the mother plant in fall.

If you choose an outdoor tree, then you need to consider '~ time.' If the species you pick requires a winter period to be dormant, then the seed will need this in order to sprout.

This phenomenon is also true of planting in the earth, but only when ~ of the soil is present to cause an impermeable layer, such as when you are planting on a layer of clay or hardpan, or you create a boundary between two dissimilar soil types.

collect seeds from trees growing in your local area planting the seeds in autumn will do just fine, however, if you want to plant seeds out of the season (during springtime for example) or if you like to grow seedlings from trees not growing in your local climate, a process called "~" ...

15 to start the ~ process. To stratify the seeds using this technique simply place them in a plastic bag with some moist (not wet!) peat moss, or a mixture of moist peat and sand. Poke some holes in the bag, you don't want it air tight.

If you live in a temperate part of the world the chances are that your seeds will need to be chilled to start them growing, this is called '~'. Put half of the seeds in a container (a plastic bag) and place them in the refrigerator (not the freezer) for a few weeks.

If you do decide to buy from Sandeman I have some good guides on growing trees from seed. ~ information etc.
If you need help, just let me know.
Cheers ...

Conifers Cones may be dried and shaken but dismantling using bonsai tools is often necessary. Many Pinus and some other conifers have small pointed seeds with a papery wing. ~ is not usually necessary.

Seed maturation is usually in a few weeks to six months after flowering, with seed dispersal shortly after maturity. Most species require ~ in order to germinate, and some seeds can remain dormant in the soil for several years before germinating.[1] ...

Use a toothbrush or similar to carefully brush of moss and lichens from trunks and surface roots
Tidy up, weed and dispose of fallen leaves
Take hardwood cuttings
Collect seeds from trees and store safely. Sow those that need ~ during the winter ...
