- Scaffolding for vines – Pines make great natural scaffolding to vining plants that can grow in the unique soil conditions created by the pine needles. The Pine tree does not bear every year, and the cones are often harvested by hand from the tree, so undergrowth should be tolerated well. Also, since many Pines take a number of years to start producing, a short lived vine can grow on the maturing Pine tree for a few years as needed.
- Tea Plant – young needles can be steeped in hot water. This tea is high in vitamins A and C.
- Wildlife shelter – mainly birds and small mammals
- Wildlife food source – many animals will eat the seeds and fruit, especially birds and small mammals
- Drought plant – Pines are tolerant of drought once established, due in part to their large taproot
- Tan/green dye from the needles
- Source of tar, pitch, rosin, turpentine, etc. I plan on writing an article detailing the production and uses of these products soon.

The female cones (strobili) bear the tasty nuts/seed, but both male and female cones are both needed for their production.
Harvesting:
The cones will ripen at various times according to the species (P. pinea ripens in April, P. koraiensis ripens in September, P. edulis and P. cembroides ripen in October). However, ripening times will vary greatly on species and local climate/enviroment.
Pine nuts are ready for harvest about 10 days before the green cones begin to open. The cones are harvested with either long poles (often bamboo), long-handled pruners, or long-handled saws which knock the cones down or by a person who climbs the tree and harvests each cone by hand (the “piñero”). The harvested cones are placed in a bag (burlap is most common) and then exposed to heat (sunlight is most common). In about 20 days, the drying process causes the cone to fully open and the nuts can be extracted, usually by swinging the bag into a hard surface causing the cones to shatter and release the seed. It is possible, but difficult to harvest the seed from the ground after the cone opens on its own. Conversely, animals are very good at harvesting fallen nuts as a food source.
The nuts will need to be shelled after collected from the cone. This can be time consuming if done by hand with a hammer. There are commercial shellers available which are rather expensive. There are also a number of plans for do-it-yourself shellers available online. I have not attempted making or using these, so I cannot speak to their efficacy; however, I hope to do some experiments with them in the future. I will share that information as I get it.
Yield: 10-20 lbs (5-10 kg) is a large crop from an average tree.
Storage: Pine nuts can be stored for many years after dried.
DESIGNING WITH THIS PLANT
- Mexican Pinyon (Pinus cembroides): Zone 5-8
- Colorado Pinyon (Pinus edulis): Zone 5-8
- Korean Nut Pine (Pinus koraiensis): Zone 3-7
- Italian Stone Pine (Pinus pinea): Zone 7-11
- Mexican Pinyon (Pinus cembroides): Zone 9-1
- Colorado Pinyon (Pinus edulis): Zone 8-5
- Korean Nut Pine (Pinus koraiensis): Zone 7-1
- Italian Stone Pine (Pinus pinea): Zone 12-9
Chill Requirement: Likely considering where this plant originates, but no reliable information is available.
Plant Type: Medium to Large Tree
Leaf Type: Evergreen
Forest Garden Use: Canopy Layer
Cultivars/Varieties: There are a many species and cultivars available
Pollination: Most species are not self-fertile (they need to be fertilized from another tree), and most are monoecious. Pines typically have male and female flowers on the same tree. Pollinated by the wind.
Flowering: Typically in the Summer months
Life Span:
- Years to Begin Bearing: 15-40 years (Korean Pine); 25-75 years (Colorado Pine). However, this really applies to the wild varieties. There are varieties of nut pines that start producing in 5-10 years (precocious varieties) that are starting to become more widely available.
- Years Between Major Crops: 2-7 years. Many trees have “bumper” years when the conditions are perfect for nut production, and there can be a number of low production years in between large harvests.
- Years of Useful Life: In general, Pine trees are long-lived trees. An Italian Stone Pine tree lives to be about 100 years old. A Mexican Pine Nut tree is just reaching maturity at 250-350 years. Many pines can live to well over 1,000 years of age.
PHYSICAL CHARACTERISTICS OF THIS PLANT
Size:
- Mexican Pinyon (Pinus cembroides): 26-66 feet (8-20 meters) tall and 15-25 feet (4.5-7.5 meters) wide with a 20 inch (50 centimeter) trunk diameter
- Colorado Pinyon (Pinus edulis): 33-66 feet (10-20 meters) tall with a 31 inch (80 centimeter) trunk diameter
- Korean Nut Pine (Pinus koraiensis): 130-160 feet (40-50 meters) tall with a 4.9-6.6 feet (1.5-2 meter) trunk diameter
- Italian Stone Pine (Pinus pinea): 39-82 feet (12-25 meters) tall and 26 feet (8 meters) wide
Roots: Most species have taproots. Some are more fibrous than others.
Growth Rate: Very slow to medium growth rate
GROWING CONDITIONS FOR THIS PLANT
Light: Prefers full sun
Shade: Does not tolerate shade
Moisture:
- Mexican Pinyon (Pinus cembroides) – Prefers dry to moist soils
- Colorado Pinyon (Pinus edulis) – Prefers rather dry soils, but tolerates moist soils
- Korean Nut Pine (Pinus koraiensis) – Prefers dry to moist soils
- Italian Stone Pine (Pinus pinea) – Prefers moist soils, but tolerates very dry soils once established
pH:
- Mexican Pinyon (Pinus cembroides): 5.1-7.0
- Colorado Pinyon (Pinus edulis): 6.1-7.0
- Korean Nut Pine (Pinus koraiensis): 5.1-7.0
- Italian Stone Pine (Pinus pinea): 5.1-7.5
Special Considerations for Growing:
- Pine roots really need to establish a symbiotic relationship with mycorrhizal fungi to grow well. Innoculation is stronly recommended. This can be as simple as obtaining some soil from an established pine forest and mixing this into the compost in the hole the seedling is placed. There are places that sell specific innoculant for specific species of pines.
- High elevation is considered a benefit for pine nut production as most Pine Nut trees are found between an elevation of 6,000-8,500 feet (1,800-2,600 meters) above sea level. It is thought that the higher elevation moderates ambient air moisture and maintains stable humidity. It appears that nut production can still be high at lower elevations if the tree has reatively constant through the Spring and Summer.
Propagation:
Typically from seed – 4-12 weeks of cold stratification improves germination rates. Due to their taproots, most pines are best planted into their permanent position as soon as possible (no more than 3 feet/90 centimeters). Some species can be propagate through cuttings.
Maintenance: Minimal.
Concerns:
- Terpene is a chemical released from the needles during rain. This has an allelopathic effect; it inhibits the growth of some other plants.
- “Pine Nut Syndrome” or “Pine Mouth” is a phenomenon where a person who eats pine nuts will develop a metallic taste in their mouth for a few days to a few weeks. This goes away on its own and has no lasting or harmful effects. No one is sure why this occurs, but it has been seem almost exclusively in Asian pine nuts. Some researchers believe it is due to only Asian pine nuts. Some believe it only occurs with nuts from a certain species, Pinus armandii. Others believe it has to do with the chemicals used in the shelling process in Asia. No one is really sure right now.

Good timing.. I ordered Korean Nut Pines a few weeks ago for spring delivery. The Siberian Dwarf might be a choice for the north edge of my main crop garden.
Where did you get the Korean Nutines. Are they good producers? Are there scarf nut pines that are good producers?
I would just like to say that I find these pages extremely informative and useful. Having just finished Geoff Lawton’s on-line permaculture course I’m really excited about applying the concepts I have learned. Next year I shall be leaving Hong Kong and returning to Dunedin in the South Island of New Zealand and the one thing I found frustrating about Geoff’s course is that the examples given were from the Permaculture Institute in the sub tropics of Australia. Hardly applicable to the southern regions of NZ. So thank you, John, for the abundance of temperate climate information you are providing. It is really appreciated.
Great post. I’ve considered buying from the Texas nursery – https://tfsapps.tamu.edu/wtn/StoreFront/Store_Prod59_Pinyon-Pine-Plastic.aspx for central Texas. Would need to put in places where it gets enough sun.
The other interest would be finding edible plants that would grow well underneath pinyon pine or serve as beneficial in some way.
Great stuff. I am keen to know about the difference in the kernels themselves, between varieties though. I have seen them vary quite widely in shape, and they seem to vary in flavour too. It’s a fuzzy recollection now, but I thought I remember gathering some as a kid that didn’t have husks?
Would be great to find what varieties people are having success with around the UK..
Nuts tastedbest when mixed with cereal flours.
[…] open the hard shells, Squirrels on the other hand have shown no interest in them. According to the Temperate Climate Permaculture website, it takes anywhere from 5 to 75 years for some Pine trees to begin producing […]
I am also interested in beneficials/ companion planting for pine nuts… the only thing i have found is that it is important to use the correct inoculant when planting. especially with very foreign types, like korean pine nuts in Vermont…
Any other advice?
I grew up in New Mexico, and I always got excited about going out to pick the pinons.
I am now living in Port St. Lucie, Fl. Where can I buy tree seedlings. I wanted to try and grow some here. I would appreciate your help.

We have 25-year old Swiss Stone pines. We live at about elevation 2,100 feet in western MD. Any idea as to when we can attempt to harvest the nuts?
Thanks.
What about harvesting the pine pollen?!
One thing I noticed where I lives is that very very often there is a pine tree, a conifer at the drip line, and a grape at the outer drip line of the conifer. Perhaps this could be used in a guid in some way?
Under “Special Considerations for growing”
“It appears that nut production can still be high at lower elevations if the tree has reatively constant through the Spring and Summer.”
Did you leave out a word? “constant humidity?”
Love the site, by the way, I can count on more comprehensive information about a plant here than most places.
[…] http://tcpermaculture.com/site/2013/11/13/permaculture-plants-pine-trees-for-pine-nuts/ […]
I’m noticing that on my laptop the last few letters (sometimes a whole word) are missing from every line of text on this site. Is the site monitored? If so is there a way to correct?
Besides all that I’m interested in collecting nuts from mature stone pines on public property next door to me. I will monitor these trees for their “good” years using your info. Thank you.
