Pine pollen harvesting comes down to a few days a year. Each spring a pine tree's male cones swell, turn from green to yellow, and then let go of their pollen in a cloud that the wind carries off within a day or two. Miss that window and the year's crop is gone. If you're a man thinking about gathering your own, or just want to know what went into the bottle you take every morning, this is how it's done and when.
What gets picked in pine pollen harvesting
Pines carry two kinds of cones. The woody ones you picture are female. The pollen comes from the male cones, small soft clusters (often called catkins or candles) that grow in bunches near the tips of the branches. Each pollen grain has two air sacs, which is why it floats so far. The New Zealand Forest Owners Association puts a mature radiata tree at about 0.5 to 0.75 kg of pollen a year, and notes that wind-carried pollen usually lands within 700 metres.
That small yield per tree, and a few days to get it, is the first thing anyone who tries it learns.
Pine pollen harvest time
Most pines shed in late winter to spring, and the timing shifts with the species and the weather. Pinus radiata, the species Mara uses, grows wild in three small coastal stands in California and on two Mexican islands, Guadalupe and Cedros. The US Forest Service's Fire Effects Information System records pollination there in January and February. In the big Southern Hemisphere plantations the season flips. DermNet, the New Zealand dermatology reference, lists the radiata pollen season as August to September, and says hot weather can stretch it.
Inside that season, the useful window is far shorter. Forager and chef Alan Bergo, who gathers pine pollen near his home in Minnesota, says it peaks for "about one day, maybe two if the wind is light." A windy afternoon can strip a stand bare.
Pine pollen time of year, by region
- Native radiata stands (California and Mexican islands): January to February
- Southern Hemisphere radiata plantations: August to September
- Minnesota, where Alan Bergo forages: usually late May
Total testosterone rose from 362.5 to 448.4 ng/dL in 8 weeks.
How is pine pollen harvested?
There are two ways, and both depend on catching the catkin at the right moment.
Forestry crews that breed pines collect pollen for seed orchards, and Rayonier, the US timber company, has described its method in detail. Crews ride hydraulic lifts into the treetops and give each catkin a squeeze test. If it snaps like a pea pod, it's too early. If yellow goo comes out, still too early. When the catkin bends without breaking and the liquid runs clear, it's ready. They clip whole clusters with pruning shears into 5 gallon buckets.
Wild foragers usually work by hand at head height. Bergo slips the flowering branch tips into a clear two gallon bag and shakes, so the pollen drops into the bag and he can see how much he's got. Catkins that fall in with it are fine.
After that, the steps look much the same:
- Dry the catkins. Rayonier spreads them on flat cardboard trays in a drying room and runs machines that pull moisture out until the pollen sits below 8% moisture.
- Sieve. As the catkins dry, the pollen falls away. A shaker or fine sieve lets the powder through and keeps back the husks. Bergo sifts twice, because the first pass turns up needles, debris and insects.
- Store cold. Rayonier bottles its pollen and keeps it in an industrial freezer until the next season. Bergo freezes his in glass with a vacuum sealed backup.
Rayonier's crews watch moisture closely for a reason. Pollen that goes into the freezer too wet can burst and is useless. Bergo, asked on his site whether pine pollen can spoil or mold, answered "Yes." The powder pulls water out of the air and clumps.
The wall around every grain
There's one more step that home harvesters skip. Each pollen grain sits inside a shell of sporopollenin, one of the toughest materials any plant makes. In 2018 a team at MIT and the Whitehead Institute, led by Jing-Ke Weng, published a study of its chemical structure in Nature Plants, working with pitch pine pollen. They described it as "extremely inert, resistant to reacting with other chemicals," held together by two kinds of chemical cross-links where most plant polymers have one.
That's why serious pine pollen is sold as "cracked cell." The wall is broken open mechanically after harvest, so what's inside isn't locked away behind a shell built to survive wind, sun and drought. A kitchen sieve can't do that.
Why most men skip the harvest and buy the extract
Put the steps together and the hard parts are clear. You get a day or two each year, from trees that may be hours away. You need dry weather on the day, a drying room after it, and a freezer to keep it. And at the end you still have whole grains in their shell.
Mara's Pine Pollen starts from wild-harvested Pinus radiata pollen that has already been cracked. It's then made as a spagyric tincture. The pollen is extracted, and the minerals left behind are returned to the liquid, so the whole plant ends up in the bottle. Simple ingredients: premium quality extract. It goes into dark Miron glass. Dark amber glass is a step in the right direction for anything plant based. Miron is the gold standard, and it keeps light off the extract for the life of the bottle.
In daily use that means a 50 ml dropper bottle in a drawer or a gym bag. One to two droppers a day, held under the tongue for 20 to 30 seconds, or stirred into water or a morning tea. The taste is soft and lightly earthy, with a faint sweetness. A bottle runs 30 to 50 days. No freezer, no clumping, no spring weekend spent up a ladder.

Add to bagWhat men have measured
Pine pollen has been gathered for a long time. Chinese herbal texts have recorded song hua fen since the Tang dynasty, and it sits in the Chinese Pharmacopoeia today. In 1971 Šaden-Krehula and colleagues isolated testosterone, epitestosterone and androstenedione from Scots pine pollen, the first time those were found in any plant.
More recently, Wolkodoff and colleagues ran a pilot with 10 men aged 47 to 78. Over 8 weeks their average total testosterone rose from 362.5 to 448.4 ng/dL, and qADAM scores (a questionnaire on energy, drive and mood) went from 23.9 to 31.7. A 2025 pilot with 11 men recorded free testosterone going from 10.48 to 11.72 ng/dL, with SHBG falling. Men who take pine pollen daily often report stronger morning wood and more drive.

Questions people ask
When is pine pollen harvested?
In late winter to spring, over a window of one or two days per stand once the male cones ripen. Radiata pine sheds in January and February in its native range and in August and September in Southern Hemisphere plantations.
Which part of the pine tree does the pollen come from?
The male cones, small soft clusters near the branch tips. The woody cones are female and don't make pollen.
Why does pine pollen need to be dried?
Wet pollen clumps and can mold. Forestry crews dry it below 8% moisture before freezing it.
What does cracked cell pine pollen mean?
Each grain has a hard sporopollenin wall. Cracked cell pollen has had that wall broken open after harvest.
