Hi Osprey,

Best is to first give them a month or two of cold moust pre-treatment: put the seeds in some damp (not dripping wet!) sterilised sand, and refrigerate at 1° to 2°C. Then sow in a well-drained potting mix.

should read: cold moist pre-treatment

Resin,

Ok, let me see if I am getting this straight. I place the seeds in a container with wet sand in the refrigerator for an entire month. Does a regular refrigerator work for that? When is the best time for sowing and depth. Is this the best time to start the procedure.

Hi Osprey,

Yes, except 'wet sand' sounds a bit too wet! Only damp, not dripping. A regular refrigerator will work, though they are (usually) a degree or two warmer than is ideal - maybe set the thermostat a little lower (but obviously not so cold that your milk freezes!)

Best time for sowing - indoors, as soon as the cold treatment is over, by the end of February. Outdoors, wait until all risk of frost is over (keep the seeds in the 'fridge until then); they will also need protection from mice, birds, etc., if sowing outdoors. Bury the seeds under their own thickness of soil (for Pseudotsuga macrocarpa, that'll be about 8-10mm deep). An acidic soil mix will reduce fungal disease risks slightly. Keep the seeds well spaced, ideally one seed per pot, both to reduce the risks of disease spreading, and also so you don't have to disentangle root systems when planting out.

Im told young pseudotsuga macrocarpa are like p menziesii
here in UK ive seen two mature ones at Bedgebury pinetum
nice trees.

So, did you call these guys? They uded to sell them...

look up www.sheffields.com they have seed

Colvo Creek Nursery has 4 inch liners of Pseudotsuga Macrocarpa for $9.00 and shipping isn't that much either on liners. They have alot of interesting plants that would be good for New Mexico, it's the only nursery I've found that is selling Picea Morrisonicola which I really want. So will Big Cone Douglas Fir grow in the southeast or is it too wet here or do they need good drainage?

Osprey,

Regarding the plants, call forestfarm.com and see if they have some plants. They sometimes have plants that are not in the catalog. This is usually due to the fact they have some plants in very small quantities.

Regarding the seeds, cold treatment may not be necessary. I would set some seeds aside and germinate them in a moist (not wet, wring out the paper towel after you have rinsed it in water) paper towel in a plastic bag at room temperature. Give it a shot, and let us know!

I have some pseudotsuga macrocarpa seeds and will
plant them in a small flower pot with peat and grit
and wait for them to germinate can take a few weeks.

Frank, I did emailed them last year, but they didn't have it in stock. I checked their webpage and seems like they don't have any still. I will try to call them.
Thank you everyone, I think I will go ahead and try to obtain my own trees from seed, hopefully I will have some trees in a couple of years

Forrest, I was thinking in getting one from Colvo's but they are too small, with that I can buy some seeds and grow them my own.

Dennis, I did called Ray from Forestfarm, but they do not have any.

It is a very nice tree and nobody seems to have it....
