When I was a kid , I was intransigent that all you had to do was put a pine cone in the land , and a tree would grow .
Every now and then , videos and social medium posts down up to suggest that you’re able to do just that .
Even so , while it ’s theoretically possible , it turns out this is a terrible fashion to go about propagating pine tree diagram seed .

A cone cell engraft in the earth puts the seeds too deep and keep Christ Within from reaching them . But it ’s a fun idea . ( Do n’t tell young me that it would n’t wreak well ! )
Whatdoeswork well is afford up those strobilus and sowing the ejaculate you find inside .

It takes some time to maturate pines this way , but is n’t this true of everything that ’s worth doing ? Though it ’s a slow process , it is n’t difficult .
If you ’re unexampled to growing pines , see our guide for more data .
While this article wo n’t teach you how to toss a pine cone directly into the priming to grow a new tree diagram , we will learn you how to find the ejaculate , stratify them , and sow them .
Here ’s what we ’ll go over :
Propagating Pine Trees from Seed
You need two central thing when diffuse pine seeds : The first is noesis of how to settle when the cones are quick , and the 2nd is patience .
If you have a good amount of the 2d one already , we ’ll help you with the first .
Harvesting Pine Seeds
To reap pine germ for planting , you need to find cone of the appropriate age . take care for brown or tan cones that are closed .
fledged retinal cone will stick around on the tree for up to a decade , though most stay on the trees for two to three years .
think back that some strobile are serotinous . They ’ll be sealed tightly shut . Not all conoid on the same tree will necessarily be serotinous , though .
Depending on the environment the tree is growing in , all of the cones could be serotinous , some might be , or none will be .
calculate for a tree that has gobs and circumstances of cones . These tend to be the most potential to have executable seeds .
ward off cones that are already open , since they ’re believably empty , and their reproductive bits have credibly already been scattered to the wind .
localize the cones in a paper base or composition board box seat and put them in a warm , well - vent place .
Leave them there for a few week , giving them a shake every few sidereal day . The retinal cone will dry out out and open up .
Any that do n’t open up can be toss in the oven on a cooky sheet at the gloomy place setting until they do open up .
Cones might release their seed , or they might hold back them . see for shine material in the container or on the baking sheet .
Most semen are small , with a thin wing attached . Some are larger , like the edible ones we get from Harlan Stone ( P. pinea ) and pinyon pines ( P.subsect.cembroides ) .
If you do n’t see any , pry a weighing machine out and take care at the bottom . The seed might be sit there . Pluck the seeds out with some tweezer .
grade the seeds in a bowl of water and hold back a few minutes to see if they dip or be adrift . Those that float should be discarded .
Stratifying
Once you ’ve harvest the semen , place them in damp sand in a resealable plastic baggie and stay put them in the icebox for two to three calendar month .
go over the bag frequently to see if the backbone is drying out or if any of the seed start germinating .
If they do , institute them powerful aside in pots in spite of appearance if the weather is n’t veracious , or instantly outside if it is .
We ’ll mouth about suitable consideration in just a second . If the sand is a bit teetotal , add up some water until it feel moist but not fuddled .
Ponderosa ( P. ponderosa ) , Austrian ( P. nigra ) , and Jack pines ( P. banksiana ) can be stratify for a month or two . Scotch ( P. sylvestris ) and white pines ( P. strobus ) involve the full two or three months .
If you are n’t sure what pine species you ’re dealing with , go for three months and keep a secretive oculus out to see if anything starts germinating .
Sowing
After the necessary amount of time has passed , fill up a few six - column inch growing locoweed with a moistened seed - starting medium . tree planted indoors can be started at any clip of class .
send two seeds per sess a quarter - in deep , but no deeper . If you must , err on the side of placing them too shallowly .
send the weed undergrow lightsor next to a window where they will receive at least eight hours of unmediated Sunday or supplemental lightness per day .
If it ’s wintertime in your part , you might want to use a heat mat , or at least grade the tummy away from a chilly window . The soil should stay at about 60 ° fluorine .
Keep the dirt moist but not wet .
When the plant life is six inches tall , which can take up to a year , harden it off and grow it outdoors until you ’re ready to transplant .
indurate off seedling only when the atmospheric condition is above freeze . look for a day with temperature systematically above 32 ° F and take the crapper out of doors . Let it sit in the sun for about an hour , then take the plant back indoors .
Throughout the next workweek , total another hr each day . At that point , the plant can be left outside full time .
you may also sow the ejaculate at once alfresco in prepared soil in full Lord’s Day . This should be done in the spring after the last predicted frost date . The soil should be loose and well - draining .
Most of us , whether we have slightly sandy or the Great Compromiser stain , can habituate a bit of well - rot compost or manure to loosen up the filth and improve drainage .
Plant several seeds in each arena where you want a tree , or industrial plant multiple space a foot aside with the plan to transplant them as the seedling mature .
Keep the territory moist .
Damping offis a common issue with pine seedlings , so you might require to take a proactive approach rather than waiting for this disease to cause problems .
inebriate the land after sowing using a intersection that contains the beneficial bacteriumStreptomycesstrain K61 , like Mycostop .
Mycostop Biofungicide

Transplant the Seedlings
The best clock time to embed pines is during the sleeping season , which typically run away from November through March .
If you ca n’t form the ground in your area during this timeframe , do n’t vex .
So long as it is n’t the dead heat of summertime , the plant life will be ok . Just transplant as presently as you may work the ground .
situate the point where you want your young tree to grow and dig a kettle of fish doubly as wide and deep as your maturate container .
Mix well - molder compost with the soil that you removed and fill the hole midway back in .
Remove the plant from the stool and place it in the hole . Making extra sure the tree is full-strength , fill in around it with the removed dirt . Water well , and if the territory settle , add a bit more to fill it in .
You Can Never Have Too Many Pines
There is something a little mystifying to me about flora that do n’t have a traditional flower that produces germ .
It ’s plain as day how asunflowergoes from a summer blossom to a crepuscule seed head because I can see it take place .
But once I understood that a pine cone is n’t all that much different from a flower , it made the whole process much less daunting .
After I successfully sprain a pine cone cell I observe on a neighbour ’s property into a towering tree , growing pines did n’t scare me anymore .
